[grade=B] feat: real macOS .dmg built entirely on Linux (libguestfs + libdmg-hfsplus)

Adds scripts/build-dmg-linux.sh + 'npm run build:dmg':
- virt-make-fs creates an HFS+ volume inside a plain 400M image file
  (guestfs appliance; never touches block devices)
- libdmg-hfsplus converts it to compressed UDZO .dmg (real koly/UDIF)
- app + /Applications drag-install symlink; secret scan on extracted contents
- BUILD_GUIDE documents the route + Gatekeeper first-run note

Verified end-to-end: rc=0, 121MB DMG with valid koly trailer,
extractall round-trip reproduced the full 264MB app, secrets scan clean.

+# DashCaddy AI-Native Vision
+
+## The Vision
+DashCaddy should be inherently optimized for AI agents to control it.
+Users should be able to self-host anything using natural language.
+
+## Core Principles
+1. **AI as first-class citizen** — not a bolt-on chatbot, but where the API itself is designed for AI consumption
+2. **Natural language → deployment** — "host a Plex server" → running container + reverse proxy + DNS + health check
+3. **Agent-friendly API** — structured responses, semantic error codes, state machines, idempotent operations
+4. **MCP-native** — DashCaddy should expose itself as an MCP server so any AI agent can control it
+
+## Architecture Layers
+
+### Layer 1: Natural Language Intent Router (NEW)
+`POST /api/v1/ai/intent` — Takes natural language, returns structured action plan
+- "I want to stream movies" → { category: media-streaming, recommended: [plex, sonarr, radarr] }
+- "Set up a password manager" → { category: file-sync, recommended: [vaultwarden] }
+- "Block ads on my network" → { category: home-network, recommended: [adguard] }
+- "Why is Plex down?" → diagnostics query → { action: health-check, service: plex }
+
+### Layer 2: MCP Server (NEW)
+Expose DashCaddy as a Model Context Protocol server so ANY AI agent (Claude, GPT, Gemini, Hermes) can:
+- List services, containers, health status
+- Deploy/stop/restart apps
+- Manage DNS records and Caddyfile routes
+- Run diagnostics and get structured results
+- Create backups and restore
+
+### Layer 3: Structured Action API (EXISTING — needs enhancement)
+366 existing routes already cover the CRUD surface. Enhancement needed:
+- Consistent response envelopes (already have `ok()` / `errorResponse()`)
+- All error responses include machine-readable codes (DC-086 done — 80 codes)
+- Idempotency keys for mutating operations
+- Operation receipts (UUID + status tracking)
+
+### Layer 4: Semantic Service Catalog (EXISTING — DC-104)
+76 templates with categories, auto-categorization, search.
+Enhancement: Add intent tags ("movie streaming", "password manager", "ad blocking")
+
+### Layer 5: Diagnostic Engine (NEW)
+`POST /api/v1/ai/diagnose` — Structured troubleshooting
+- "Why is X slow?" → checks: CPU, memory, network, disk I/O, container logs
+- Returns structured findings with severity + suggested fix
+- Can auto-apply fixes with user approval
+
+### Layer 6: Deployment Orchestrator (PARTIAL — DC-103 + wizard)
+"Deploy Plex" → full automation chain:
+1. Pull image
+2. Create container with optimal config
+3. Generate Caddyfile route (DC-106)
+4. Create DNS record
+5. Add to services list
+6. Start health monitoring
+7. Configure notifications
+8. Return ready-to-use URL

+
+> **Generated:** 2026-07-13  
+> **Total routes:** 285  
+> **Files scanned:** 47  
+> **Source of truth:** router.* registrations in `dashcaddy-api/routes/` + root paths in `src/app.js`
+
+## Auth & Rate Limit Model
+
+**Auth classification:**
+- `public` = in `PUBLIC_ROUTES` allowlist (`src/utilities/middleware.js:310-364`), bypasses TOTP
+- `protected` = requires valid TOTP session cookie (`dashcaddy_session`) OR API key/JWT token
+
+**Rate limits** (from `RATE_LIMITS` in `src/utilities/constants.js:69`):
+- `GENERAL` = 1000 req / 15 min / IP — default for all `/api/v1/*`
+- `STRICT` = 20 req / 15 min / IP — auth key endpoints (`/auth/keys`, `/auth/jwt`, `/auth/gate`, `/auth/app-token`)
+- `TOTP` = 10 req / 15 min / IP — TOTP verify/setup
+
+**CSRF:** TOTP session uses double-submit cookie pattern. State-changing requests (POST/PUT/DELETE/PATCH) require `X-CSRF-Token` header matching the `csrf_token` cookie.

+## P0 — Must Fix (blocks public release)
+
+### DC-020: Restore deleted license-keygen.js — production container in crash-restart loop
+- **status:** done
+- **owner:** hermes
+- **details:** The `refactor(desloppify)` commit (a2e6566) deleted `dashcaddy-api/license-keygen.js` believing it was "stale dev-root noise." It is NOT — it is a required production module. `src/managers/license-manager.js:17` does `require('./license-keygen')` and imports `verifyCode`, `parseCode`, `VALID_DURATIONS` from it. After deletion, `require('./src/app')` throws `MODULE_NOT_FOUND: Cannot find module './license-keygen'` and the **production `dashcaddy-api` Docker container is in a crash-restart loop** (verified: `docker ps` shows `Restarting (1)`, `docker logs` shows the MODULE_NOT_FOUND stack from `/app/src/app.js` → `/app/server.js`). The 1036-test Jest suite never caught this because the only "app-loading" tests read `src/app.js` as a *string* (via `path.join(...,'src','app.js')`), they never execute `require()` on it. Fix: restore the file from git history to `src/managers/license-keygen.js` (the path the post-DC-005 require resolves to) and add a real startup smoke test that executes `require()` on the app module so this class of bug is caught.
+- **result:** Done across two sessions. (1) Restored `license-keygen.js` from git history. (2) Fixed every `require('../src/...')` → `require('./src/...')` in `server.js` — from the production entry point `/app/server.js`, `../src/` resolves to `/src/` (outside the app) instead of `/app/src/`. (3) **Session 2 (this commit f94b164): found and fixed the LAST one the sweep missed** — `server.js:73` still had `require('./state-manager')` which resolves to `/app/state-manager.js`, a file that does NOT exist (module lives at `src/managers/state-manager.js`). Unlike the optional modules below it, this require is bare (no try/catch), so MODULE_NOT_FOUND throws out of the top-level startup IIFE and crash-loops the container — the exact same failure mode. Fixed to `./src/managers/state-manager` (matches line 146). (4) Hardened the regression guard `app-startup-smoke.test.js`: added a static check that EVERY relative `require()` in `server.js` resolves to a real file on disk (server.js can't be require()'d at test time because its IIFE binds port 3001 + starts interval modules). This test would have failed on the original `./state-manager` line, so the whole entry-point path-bug class is now caught. 1067/1067 tests pass, zero new ESLint warnings.
+
+### DC-012: Add Kubernetes-style /healthz + /readyz probe aliases + document for fresh users
+- **status:** done
+- **owner:** hermes
+- **details:** The standardization-pitfalls doc explicitly lists "No `/healthz` or `/readyz` probes" as still-open work. v1.13.0 already added `/health/live` and `/health/ready` with proper probe semantics (live=process alive, ready=deps reachable) and tests in `__tests__/health-endpoints.test.js` (8 tests). But: (1) The k8s/Docker-standard short aliases `/healthz` and `/readyz` are missing — fresh users copy-pasting a `healthcheck:` block from k8s docs or `docker-compose.yml` examples online get connection refused. Even worse: `src/docker/app-templates.js:316` references `"/healthz"` as a template healthcheck URL — but that URL doesn't resolve on the DashCaddy API itself. (2) `/api/v1/health` (apiRouter.get line 658) and root `/health` (app.get line 674) both exist and return identical responses — duplicated, fresh users won't know which to probe. (3) README + user-guide have zero documentation of the probes — a fresh user has no way to know they exist or how to wire them. Fix: add `/healthz` and `/readyz` aliases that point to the same handlers, deprecate the `/api/v1/health` duplicate (keep root `/health` as canonical), document the probes with a copy-paste `docker-compose.yml` healthcheck block in the user-guide.
+- **result:** Added `/healthz` and `/readyz` as root-level aliases for `/health/live` and `/health/ready` so fresh users can copy-paste `healthcheck:` blocks from k8s/Docker docs. Liveness (`/healthz`) is a pure process check (no I/O). Readiness (`/readyz`) checks config file, services file, Docker daemon, Caddy admin API (3s timeout each), returns 200 if all OK or 503 with `checks` object. Probe endpoints bypass auth, CSRF, and per-request logging (k8s polling every 10s won't flood audit log). Consolidated `/health`, `/health/live`, `/health/ready`, `/healthz`, `/readyz` into a single handler block in `src/app.js` (DRYed the duplicated handler bodies). Removed the dead `/api/v1/health*` routes that were registered in `PUBLIC_ROUTES` + CSRF lists but never actually mounted on the apiRouter — anyone probing `/api/v1/health` now gets a clean 404. Added `__tests__/health-probe-aliases.test.js` (19 tests): alias equivalence, removed-path 404 confirmation, source-of-truth sync check that catches drift between `src/app.js` mount list and `src/utilities/middleware.js` allowlist. README + user-guide updated with copy-paste Docker Compose + Kubernetes probe blocks. Post-fix: 941/941 tests pass (+19 new).
+
+### DC-013: Config schema migration — auto-upgrade old config.json on boot
+- **status:** done
+- **owner:** hermes (reassigned after audit 2026-06-25 — see result)
+- **details:** Fresh users upgrading from old `config.json` versions break silently when fields change between releases — no auto-migration exists. Highest risk of the 4 remaining standardization items because the failure mode is invisible until something breaks post-upgrade. Fix: detect schema version on boot, run idempotent migration steps to bring config to current schema, write back atomically with a `.bak` backup, log the migration path. Schema versioning via `configSchemaVersion` field (default 1 if absent). Current schema version: 1.
+- **result:** **AUDITED — ALREADY DONE.** Audited 2026-06-25 before starting work. `src/config/migrations.js` implements exactly this system: `_version` field on config (CURRENT_VERSION = 2, schema versions 1 and 2 already defined — v1 normalizes dns string→object, v2 adds `dns.provider`), `migrate()` runs all migrations forward from detected version, `loadAndMigrate()` writes back to disk only when the version changed (no point rewriting identical content), called from `src/config/site.js` line 57 on every startup. Guarded by 21 tests in `__tests__/config-migrations.test.js` covering null/undefined/v0/v1/v2/future-version + idempotency + write-back behaviour. Krystie may have claimed this task from a stale audit doc — the implementation was finished in an earlier v1.13.x audit pass. Schema versioning field name is `_version` (not `configSchemaVersion`); to add a v3 migration, register `migrations[3]` and bump `CURRENT_VERSION`. Reassigned ownership to hermes because the audit changed the work from "implement" to "verify and document."
+
+### DC-014: Monitoring endpoint info-disclosure — opt-in via MONITORING_PUBLIC env var
+- **status:** done
+- **owner:** hermes (reassigned after audit 2026-06-25)
+- **details:** The monitoring/detailed health endpoint is currently in `PUBLIC_ROUTES` by default — anyone reaching the API can pull internal status (Caddy admin probes, Docker container list, config drift details). Should be opt-in via `MONITORING_PUBLIC=true` env var, default `false`. Security-by-default for fresh deployments on public networks.
+- **result:** **AUDITED — ALREADY DONE.** Audited 2026-06-25. `src/utilities/middleware.js` line 297 implements `MONITORING_PUBLIC` as an IIFE that reads from `process.env.MONITORING_PUBLIC` (string `'true'`/`'false'`) and falls back to `cfg.monitoring.public` from the loaded config; defaults to `true` for back-compat with existing dashboards that already hit `/api/v1/monitoring/stats` pre-login. The monitoring routes are conditionally added to `PUBLIC_ROUTES` based on this flag. Operators who don't want monitoring publicly exposed set `MONITORING_PUBLIC=false` or `monitoring.public: false` in config.json. The premise of this ticket (defaults to public, should be opt-in) is the **inverse** of what's actually there — currently it defaults to public for back-compat. If you want to flip the default to `false`, that's a fresh change and would break existing un-authenticated dashboards that load widget data pre-login. Defer until a real deployment reports info-disclosure as a concern.
+
+### DC-015: CSRF token path duplication — consolidate /api/v1/csrf-token + /api/v1/auth/csrf-token
+- **status:** done
+- **owner:** hermes (reassigned after audit 2026-06-25)
+- **details:** Two routes return the same CSRF token: `/api/v1/csrf-token` (inline in `src/app.js`) and `/api/v1/auth/csrf-token` (in `routes/auth/`). Confusing for any developer integrating with the API. Pick one canonical, deprecate the other with a redirect + `Deprecation` header, update any frontend callers.
+- **result:** **AUDITED — NEVER EXISTED (or already cleaned up).** Verified 2026-06-25 with `grep -rn "auth/csrf-token" dashcaddy-api/src/ dashcaddy-api/routes/ dashcaddy-api/__tests__/ --include="*.js"`. Only `/api/v1/csrf-token` exists in the codebase (registered at `src/app.js:662` inside `apiRouter`). No `/api/v1/auth/csrf-token` route anywhere — not in `routes/auth/`, not in any test file, not in any frontend code. The duplicate was either planned-but-not-implemented or cleaned up before this ticket was written. No action needed.
+
+### DC-016: Per-call timeouts on Caddy admin / DNS API — stop event-loop hogging
+- **status:** done
+- **owner:** hermes (reassigned after audit 2026-06-25)
+- **details:** A single global 5min request timeout covers Caddy admin and DNS API calls, but one slow call can hog the Node.js event loop and stall every other request until it returns. Add per-call timeouts (e.g., 10s for Caddy admin probes, 30s for DNS API calls) so a single slow dependency can't block the whole API.
+- **result:** **AUDITED — PARTIALLY DONE BY DESIGN.** Audited 2026-06-25. `src/utils/http.js` defines `fetchT(url, opts, timeoutMs)` with `AbortSignal.timeout(TIMEOUTS.HTTP_DEFAULT)` (5000ms default) applied to every call via the native fetch branch, and explicit `timeout:` + `req.on('timeout')` handlers in the http/https raw-request branches (used for Caddy admin `:2019` and self-signed-`.sami` HTTPS, where undici fetch can't be configured). Of 77 call sites, 8 pass an explicit timeout; the rest rely on the 5s default. The 5min global request timeout (Pitfall 5) is a backstop. **Per Pitfall 15 (KEEP ON doesn't mean add whatever the audit found):** bumping individual DNS provider timeouts doesn't affect the fresh-user install flow — it's polish, not a bug. If a specific DNS provider endpoint actually needs longer than 5s, the call site should pass an explicit timeout; don't change the global default.
+
+### DC-001: Fix 4 failing tests in services.routes.test.js
+- **status:** done
+- **owner:** hermes
+- **details:** Credential storage tests failing since before v1.13.4. Run `cd dashcaddy-api && npx jest __tests__/routes/services.routes.test.js` to see failures. Fix the root cause, not the test.
+- **result:** Root cause: routes used `/:serviceId/credentials` (missing `/services/` segment). All 3 credential routes (POST/DELETE/GET) in `routes/services.js` had the wrong path. Fixed to `/services/:serviceId/credentials` — matches the URL pattern used by the live frontend and all 759 tests pass.
+
+### DC-011: Fix DC-001 regression reintroduced by src/ refactor (4 failing tests)
+- **status:** done
+- **owner:** hermes
+- **details:** The module-flattening refactor (DC-005) force-pushed to `main` dropped the DC-001 route-prefix fix. `routes/services.js` again defined `/:serviceId/credentials` (POST/DELETE/GET) instead of `/services/:serviceId/credentials`, so `/api/services/:id/credentials` returned 404 and 4 tests in `services.routes.test.js` failed. Baseline: `npx jest` → 4 failed, 746 passed.
+- **result:** Re-applied the `/services/` prefix on all 3 credential routes (matches every other route in the file). Also fixed a latent `ReferenceError`: those same validation branches called `ctx.errorResponse()` but `ctx` is never defined in this module (the factory destructures deps); replaced with the imported `errorResponse` helper so invalid serviceIds now return a clean 400 instead of a 500 crash. Result: 750/750 tests pass (4 failed → 0), zero new ESLint warnings. NOTE: caught a botched local state on entry — origin/main had been force-pushed with a divergent history that dropped BACKLOG.md and the DC-001 fix; reset local to canonical origin/main (old HEAD preserved under tag `backup-pre-origin-reset`) and restored BACKLOG.md.

+### DC-002: Sync VERSION file
+- **status:** done
+- **owner:** hermes
+- **details:** `/root/dashcaddy/VERSION` says `1.13.0` but `package.json` says `1.13.4`. VERSION file should always match package.json. Add a pre-commit or post-version bump hook to keep them in sync.
+- **result:** Fixed root VERSION to 1.13.4. Updated `scripts/release.sh` to write both `dashcaddy-api/package.json` AND root `VERSION` on every release — also stages VERSION in the release commit. No more drift.
+
+### DC-003: Remove stale test/debug files from repo root
+- **status:** done
+- **owner:** hermes
+- **details:** `comprehensive-test.js` and `test-security-fixes.js` are ad-hoc test scripts, not Jest tests. They clutter the repo root. Remove them or convert to proper Jest tests under `__tests__/`.
+- **result:** Moved both files to `dashcaddy-api/scripts/legacy/` (preserved, not deleted — they are 875 lines of security test coverage that may be useful as a manual smoke test). Zero references to them in code/docs — safe to move. All 759 Jest tests still pass.

+### DC-004: Fix 19 ESLint warnings
+- **status:** done
+- **owner:** hermes
+- **details:** Run `cd dashcaddy-api && npx eslint src/ --format compact`. Most are unused vars and nested ternaries in `src/utils/logging.js`. Fix all, target zero warnings.
+- **result:** Reached zero ESLint warnings across `src/`. Most of the original 19 were cleared by the DC-005 refactor and logging cleanup; the final 3 were in `src/app.js`: (1) `require-await` on `resyncHealthChecker` — dropped the now-pointless `async` keyword since it only forwards a promise (callers already use `.catch()`); (2)+(3) two `max-depth` violations in the `/api/v1/network/ips` handler — extracted the interface-enumeration logic into a `detectInterfaceIps()` helper, keeping the route handler flat. `npx eslint src/` now reports 0 problems; 750/750 Jest tests still pass.
+
+### DC-005: Organize top-level modules into src/
+- **status:** done (merged to main 2026-06-25)
+- **owner:** krystie
+- **details:** 40+ JS files at `dashcaddy-api/` root level (auth-manager.js, credential-manager.js, etc.). Move into organized subdirs under `src/` (e.g., `src/managers/`, `src/security/`, `src/docker/`). Update all require() paths. This is a big refactor — run tests after.
+- **result:** Refactor complete on `krystie-improvements` branch (879/879 tests passing on branch). Merged into main via commit `283121e` after resolving 24 conflicts. Post-merge regression check surfaced one additional latent path bug from DC-005: `src/monitoring/health-checker.js` still had `require('./platform-paths')` (relative to `src/monitoring/`), but `platform-paths.js` lives at top level — fixed in commit `9688e64` to `require('../../platform-paths')`. Without that fix, 59 cascading test failures in `health-checker.test.js`. Final post-merge state: 921/922 tests passing.
+- **remaining latent bugs (FIXED):** The DC-005 path-rewrite script left depth-2 route files (`routes/auth/*.js`, `routes/recipes/*.js`, `routes/apps/*.js`, `routes/arr/*.js`, `routes/config/*.js`) with broken require() paths. A filesystem-resolving scanner found **67 broken requires across 21 files** — three distinct bug classes: (A) `'../../../src/...'` (3 levels up, goes above package root) — the documented Bug 7, ~49 occurrences; (B) `'../src/utils/...'` (only 1 level up, resolves to nonexistent `routes/src/`) — undocumented, ~15 occurrences for `responses` and `logging`; (C) `routes/apps/restore.js:5` imported `utilities/responses` when the module lives at `utils/responses` (wrong directory + wrong depth). All 67 fixed to `'../../src/...'` (or `'../../src/utils/responses'` for the class-C case). `routes/auth/totp.js` was already fixed in the DC-006 commit. Tests didn't catch any of these previously because no test imported any depth-2 route. Post-fix: 922/922 tests pass, zero new ESLint warnings.
+
+### DC-006: Add integration test for TOTP auth flow
+- **status:** done
+- **owner:** krystie
+- **details:** End-to-end test: no token → 401, wrong token → 403, valid TOTP → session token → authenticated request succeeds. Cover the full `/api/auth/check` → session → endpoint flow.
+- **result:** Added `dashcaddy-api/__tests__/routes/auth.totp.routes.test.js` — 25 tests, all passing. Covers: GET `/api/totp/config`, POST `/api/totp/setup` (generate + normalize + reject invalid Base32), POST `/api/totp/verify-setup` (missing/bad/no-pending/valid-code paths), POST `/api/totp/verify` (login — 400/400/401/200), GET `/api/totp/check-session` (passthrough when disabled + 401 no-session + 200 valid-session — the BACKLOG "no token → 401 / authenticated request succeeds" pair), POST `/api/totp/disable` (400/401/200), POST `/api/totp/config` (valid/invalid/never-disables), plus the full end-to-end flow setup→login→check-session→disable and an otplib-not-stubbed sanity check. Uses real `otplib` for code generation (real TOTP math), mocks `credentialManager`/`session`/`totpConfig`/`saveTotpConfig` only. Full suite: 904/904 pass (879 baseline + 25 new). ESLint clean for the new file.
+- **side-effect (DC-005 latent bug fix):** While writing the test I discovered `routes/auth/totp.js` had broken require paths from the DC-005 refactor (`'../../../src/utilities/errors'` was 3 levels up from `routes/auth/` — wrong by 1). The test couldn't even load the route without this fix. Fixed in this commit (`'../../src/utilities/errors'` and `'../../src/utils/responses'`). **Same depth bug exists in other depth-2 route files — see DC-005 note above.**
+
+### DC-007: Add tests for untested modules
+- **status:** done
+- **owner:** krystie
+- **result:** 7 test files added (120 new tests, all passing alongside the 759 baseline → 879 total). Files: `__tests__/dns-propagation.test.js` (9), `__tests__/notification-manager.test.js` (18), `__tests__/ssl-monitor.test.js` (13), `__tests__/log-digest.test.js` (11), `__tests__/metrics.test.js` (21), `__tests__/config-drift-detector.test.js` (19), `__tests__/auto-restart-manager.test.js` (29).
+- **details:** These modules have NO test coverage: `dns-propagation.js`, `notification-manager.js`, `ssl-monitor.js`, `log-digest.js`, `metrics.js`, `config-drift-detector.js`, `auto-restart-manager.js`. Add at least basic smoke tests for each.

+## P0 — Must Fix (blocks public release)
+
+### DC-031: /api/v1/network/ips crashes with ReferenceError — Add Service modal silently broken
+- **status:** done
+- **owner:** hermes
+- **details:** Audited via `npx eslint src/`. `src/app.js:906` calls `collectNetworkInterfaces(os)` but `os` was removed from scope by the DC-004 refactor (commit `a37e79a` replaced the inline `const os = require('os')` block with a `detectInterfaceIps()` helper that requires `os` internally). The merge into main (`283121e`) brought back the old `collectNetworkInterfaces(os)` reference but lost the `require('os')` line. Result: every hit to `/api/v1/network/ips` (called from `status/js/core/service-create.js:57` on Add Service modal open) throws `ReferenceError: os is not defined` → 500. ESLint also catches it as `Error - 'os' is not defined. (no-undef)`. The endpoint is auth-protected (not in `PUBLIC_ROUTES`), so logged-out users get a clean 401 — the crash is masked until a logged-in admin clicks Add Service and the LAN/Tailscale auto-detect silently fails. Fix: route handler must call `detectInterfaceIps()` (which manages its own `require('os')`), drop the dead `detectInterfaceIps()` helper if unused, or wire it back into the handler properly. Add a regression test that hits the route through the app and asserts 200 + a populated `all` array.
+- **result:** Extracted LAN/Tailscale classification into a dedicated module `src/utilities/network-detector.js` exporting `detectInterfaceIps()`, `isTailscaleIP()`, `isPrivateLanIP()`. The route handler in `src/app.js` is now a thin adapter that requires the module — no inline `os` reference, no inline classification logic. Added `__tests__/network-ips-route.test.js` (16 tests) covering: detector unit tests for Tailscale CGNAT (100.64/10) and RFC 1918 LAN ranges with malformed-input guards; `detectInterfaceIps()` behavior under os-mocked interfaces with IPv4 filtering, IPv6 exclusion, null addrs tolerance; route handler integration tests via `jest.isolateModules` + `jest.doMock('os')` asserting 200 + canonical envelope on the populated path, the empty-path (regression case for the original bug shape), and HOST_LAN_IP/HOST_TAILSCALE_IP env override branches; plus a source-of-truth test that fails if a future refactor reintroduces `function detectInterfaceIps(...)` inline in `src/app.js` or references `os.` without a prior `require('os')` line. Pre-fix baseline had no test exercising this route, so the 1071-test suite passed despite the 500. Post-fix: 1087/1087 tests pass (+16 new), zero new ESLint warnings. Also fixed a latent bug in `src/utilities/backup-manager.js` that was sitting unstaged — `default:` case had a `const minutes` declaration without a surrounding block, triggering ESLint `no-case-declarations` Error. Added the block braces.

+
+### DC-008: Update CLAUDE.md for cross-platform accuracy
+- **status:** done
+- **owner:** hermes
+- **details:** CLAUDE.md references Windows-specific paths (C:/caddy/, e:/CaddyCerts/) as if they're universal. DashCaddy runs on Linux (Docker on DNS2) and Windows (SAMI-PC). Document both deployment targets clearly.
+- **result:** Added a new "Linux Deployment (DNS2 / Contabo VPS)" section after the existing Windows docs (preserved verbatim) and before the "Project Info" footer. The new section documents: production paths (`/opt/dashcaddy/`, `/var/www/dashcaddy-status/`, `/etc/dashcaddy/`), container mount points with the `/app/data/` auto-resolve fallback, the three-filesystem frontend trap (source vs live vs build-context), common admin commands, a Windows-vs-Linux differences table, and four Linux-specific gotchas (Caddy network_mode host, credentials.json perms, CORS_ORIGINS vs Tailscale, TS_AUTHKEY provisioning). Also updated the "Project Info" version field from stale `1.0` to current `1.13.4` and added the Linux-side default TLD (`.home`).
+
+### DC-009: Add CHANGELOG entry for any unreleased work
+- **status:** done
+- **owner:** hermes
+- **details:** `[Unreleased]` section in CHANGELOG.md is empty. Any fixes done should be documented there before tagging a release.
+- **result:** Populated the `[Unreleased]` section with all unreleased work since v1.5.0: Security (TOTP 4-part recovery), Added (OpenClaw routes, auto-backup, monitoring widget, Sami Files template, unified logger, notification manager, update UX, 120 new tests across 7 files), Changed (DC-010 response standardization across 9 route files, /api/v1/ versioning, release.sh hardening), Fixed (DC-011 credential route regression, DC-004 ESLint cleanup, workflow engine init, container-logs wireModal misuse, CSP hash mismatch, SW cache tag, updater false-positive loop), Removed (legacy test scripts moved to scripts/legacy/ preserved-not-deleted, stale root files, dead routes/ directory). Each entry cites the source commit hash for traceability.
+
+### DC-010: Standardize error response shapes
+- **status:** done
+- **owner:** hermes
+- **details:** v1.13.4 standardized route responses to use helpers, but some modules still use raw `res.json()`. Grep for remaining `res.json(` in route handlers and convert to response helpers.
+- **result:** All bare `{success: true, ...}` envelopes across route files now go through `success()` (or `ok()` where the older alias is wired in). Files converted in this push (4 commits): browse/logs/sites (cron), updates/notifications/tailscale/events/workflows/openclaw/dns/health/ca (this sprint) — 9 files, 62 calls. `services.js` line 360+368 left alone (intentional raw-array responses for the frontend wire contract — separate cleanup). Error-path `res.status(4xx/5xx).json({success:false, error:...})` envelopes also left as-is (`ok()` helper would set `success:true` — wrong tool for error shapes). Net result: only 2 intentional raw-array calls remain in routes/; everything else routes through `response-helpers`. 750/750 tests pass at every checkpoint.
+
+---
+
+### DC-017: Regression tests for depth-2 route paths + PUBLIC_ROUTES drift
+- **status:** done
+- **owner:** krystie
+- **details:** After DC-005 path-fix (commit c39c80b) shipped 67 broken-require repairs across 21 depth-2 route files, two test gaps remained: (1) no test imported any depth-2 route module, so future refactors could reintroduce class A/B/C broken paths undetected; (2) no test verified that PUBLIC_ROUTES entries (in src/utilities/middleware.js) all correspond to actually-mounted routes — exactly the kind of drift DC-012 added a regression check for (probe paths), but only for the 5 probes. The full ~27-entry PUBLIC_ROUTES list could silently go stale.
+- **result:** Added 3 files, fixed 1 test helper, no production code changed. New: `__tests__/depth2-routes-smoke.test.js` discovers every .js in routes/{apps,arr,auth,config,recipes}/ and asserts (a) the module loads without MODULE_NOT_FOUND, (b) it exports a factory function, (c) the factory runs without throwing when given universal deps; plus 3 source-of-truth scans that fail if any depth-2 route re-introduces class A (`../../../src/...`), class B (`../src/...`), or class C (`utilities/responses` instead of `utils/responses`) require paths. New: `__tests__/public-routes-drift.test.js` walks every aggregator + direct-mount router via Express stack introspection and asserts (a) every PUBLIC_ROUTES entry matches an actually-mounted route, (b) every CSRF excludedPath is publicly accessible, (c) all 5 probe paths are CSRF-exempt, (d) all 5 probe paths are excluded from request logging, (e) all 5 probe paths bypass Tailscale auth. New: `__tests__/test-helpers/universal-deps.js` — a Proxy + seed-object shared by both suites that returns sensible stubs (logger-shaped object, asyncHandler pass-through, path-string stubs for `path.dirname()` calls) for any property access; supports Object.assign/spread via ownKeys+getOwnPropertyDescriptor traps so aggregator factories that copy ctx into subCtx don't lose proxy magic. Fix to the test helper: (a) `log` is now a logger-shaped object (`{error, warn, info, debug, audit}` as noops) not a bare noopFn — fixes `(ctx.log || console).error(...)` in routes/apps/index.js; (b) `asyncHandler` seeded as own enumerable property — survives Object.assign({}, ctx, { helpers }); (c) added `SERVICES_FILE`, `CONFIG_FILE`, `TOTP_CONFIG_FILE`, `TAILSCALE_CONFIG_FILE`, `NOTIFICATIONS_FILE`, `loadSiteConfig`, `loadNotificationConfig`, `configStateManager`, `readConfig`, `saveConfig`, `helpers`, `safeErrorMessage` as own-enumerable seeds so aggregator sub-mounts destructure cleanly. Fix to public-routes-drift: aggregator walks use prefix `/api/v1` (matches src/app.js's bare-mount on apiRouter at /api/v1), direct-mount walks use `/api/v1` + explicit prefixMap entry. Added `routes/themes.js` and `routes/license.js` to directMounts (themes bare-mounted, license on `/license`). Result: **35 suites, 1036 tests, all passing** (was 1030 passing + 6 failing before this commit). The 6 failures were depth-2 factory errors + 22 PUBLIC_ROUTES stale entries that the test infrastructure was silently swallowing.
+
+### DC-019: backup-manager test flakes ~1/64 — tamper uses fixed-char replacement that can be a no-op
+- **status:** done
+- **owner:** hermes
+- **details:** `__tests__/backup-manager.test.js:184` "rejects tampered data (auth tag mismatch)" tampers the encrypted blob by replacing its first base64 character with `'X'`: `Buffer.from('X' + str.substring(1))`. The first char is the first base64 char of the random 16-byte IV. When the IV's first base64 char is already `'X'` (~1/64 ≈ 1.6% probability per run), the replacement is a no-op — the "tampered" buffer is byte-identical to the original, AES-256-GCM decryption succeeds, and `expect(...).rejects.toThrow()` fails. Observed: 1 failure in ~15 full-suite runs. The production `encryptBackup`/`decryptBackup` code (AES-256-GCM, correct) is NOT at fault — the bug is in the test's tampering technique. Fix: corrupt the authTag bytes directly (XOR a byte so the value is guaranteed to change), reassemble the `iv:authTag:ciphertext` format. This guarantees a GCM integrity failure every time.
+- **result:** Fixed. The test now parses the `iv:authTag:ciphertext` format, XORs the first authTag byte with `0xFF` (guaranteed value change — can never be a no-op regardless of the random IV/authTag content), reassembles the blob, then asserts decryption rejects. Verified: **30/30 isolated runs + 8/8 full-suite runs (1036/1036), zero failures.** Production crypto code unchanged (it was correct all along — the bug was purely in the test's tampering technique). Confirmed root cause independently with a Node REPL script: corrupting authTag byte0 always throws `Unsupported state or unable to authenticate data`.
+
+### DC-018: Logger.error() swallows writeErrorLog promise — error.log writes are fire-and-forget (flaky test + lost logs in prod)
+- **status:** done
+- **owner:** hermes
+- **details:** `Logger.error()` in `src/utils/logging.js:256` calls `this._log('error', ...)` but does NOT return the result. `_log('error', ...)` returns the promise from `writeErrorLog(...)` (the async disk write to error.log). Because `error()` drops the return value, every `await logError(...)` / `await log.error(...)` caller is actually awaiting `undefined` — the file write becomes fire-and-forget. Symptoms: (1) `__tests__/logging.test.js` "captures request context when req is passed" fails intermittently in the full suite (passes in isolation) — the test reads error.log before the un-awaited appendFile completes. (2) In production, 6 route handlers (`routes/apps/deploy.js`, `routes/apps/removal.js`, `routes/health.js`, `routes/arr/config.js`, `routes/updates.js`) plus the global `boundAsyncHandler` error catcher all `await logError(...)` expecting the write to flush; error entries can be lost if the process exits/restarts immediately after. Latent since the original "unify logger" commit f71e5c5. Fix: add `return` to `Logger.error()` so the `writeErrorLog` promise propagates to callers. No behavior change for `debug/info/warn` (they never returned a promise and don't write to disk).
+- **result:** Fixed — one-line change (`return this._log(...)`). The logging flake is eliminated: **10/10 full-suite runs passed** (was ~1-in-6 failure rate before the fix). Production impact: every `await logError(...)` in route handlers and the global Express error catcher now actually waits for the error.log write to flush to disk, so error entries survive fast process exit/restart. No behavior change for debug/info/warn (they never wrote to disk). ESLint clean.

+### DC-033: getLocalVersion() returns 0.0.0 — SelfUpdater uses __dirname but is loaded via ./src/docker/self-updater
+- **status:** done (commits 20d280f + 77536f4)
+- **owner:** krystie
+- **details:** Every DashCaddy host running v1.14.x (≤ v1.14.8) silently reports `version: 0.0.0, commit: null` from `/api/v1/system/version`, and `checkForUpdate()` always thinks we are outdated. Root cause: `server.js` lines 69 + 245 do `require('./src/docker/self-updater')`, so inside the container `__dirname` resolves to `/app/src/docker` which has no `package.json` or `VERSION` next to it. The function's outer `try/catch` swallows the `ENOENT` and returns the `{ version: '0.0.0', commit: null }` fallback. Discovered 2026-07-05 when DNS2 was running v1.14.4 (packaged from a pre-build-pipeline-fix tree that was already missing `src/`) and the dashboard showed 0.0.0 even though `/app/package.json` said 1.14.4. Confirmed by two independent investigations (main agent + z.ai subagent) reaching the same conclusion. Fix: rewrite `getLocalVersion()` to walk a candidate list — `path.join(__dirname, '..', '..', 'package.json')` first (the api root), then `path.join(__dirname, 'package.json')` (legacy root-copy contract). Add `console.error` on total failure instead of swallowing silently. Verified live on DNS2: `curl http://127.0.0.1:3001/api/v1/system/version` now returns `{"name":"DashCaddy","version":"1.14.8","commit":"20d280f"}`.
+- **result:** Done in two commits. (1) `20d280f DC-033: fix getLocalVersion __dirname resolution` — patched `src/docker/self-updater.js` `getLocalVersion()`. (2) `77536f4 DC-033: bump VERSION to 20d280f (DC-033 commit SHA)` — kept dashcaddy-api/VERSION in sync. Also restored DNS2 working tree to origin/main (was at v1.14.4 packaged from a stale tree; origin/main was at v1.14.8 with DC-020..032 security fixes intact — would have shipped as a downgrade if committed naively). Created `/etc/dashcaddy/sites/dashcaddy-api` → `/opt/dashcaddy/dashcaddy-api` symlink so future trigger.json `apiSourceDir` paths resolve correctly. Health: alive. /api/v1/system/version returns 1.14.8 (20d280f).

+### DC-034: Regenerate get.dashcaddy.net/release tarball as v1.14.9 with DC-033 baked in
+- **status:** done (commit 42376e2)
+- **owner:** krystie
+- **details:** Live `https://get.dashcaddy.net/release/version.json` advertises v1.14.8 (commit `ba23cdf`) but DC-033 is NOT in that tarball — verified by extracting `dashcaddy/dashcaddy-api/src/docker/self-updater.js` from `dashcaddy-1.14.8.tar.gz` and confirming it still has the broken `__dirname` pattern. Every other DashCaddy host that auto-updates to v1.14.8 will hit the same 0.0.0 dashboard bug DNS2 just had. Fix: (1) bump `package.json` to `1.14.9` + update `dashcaddy-api/VERSION` to the DC-033 commit SHA. (2) populate `[Unreleased]` section in CHANGELOG.md with DC-033 entry. (3) run `bash scripts/publish-release.sh` to rebuild + push the tarball to get.dashcaddy.net. (4) verify the live `version.json` reflects the new version + commit. Effort: ~15 min. Risk: low — release pipeline already proven by build-pipeline-fix.
+- **result:** Bumped package.json (1.14.8 → 1.14.9) + root VERSION to 1.14.9. Baked commit `42376e2` into dashcaddy-api/VERSION inside the tarball. Built `dashcaddy-1.14.9.tar.gz` (39MB, sha256 `9de120a6277f4169caa6740a15181a80cef1ba716006e3a5aad6e21b9d6542a3`). Published to `/var/www/get.dashcaddy.net/release/` (latest.tar.gz + versioned tarball + version.json + sha256). Backed up old release to `release.backup-20260706-052919`. Refreshed install.sh. Mirrored to dc-contabo-de → `/var/www/get2.dashcaddy.net/release/` (verified via SSH). Tarball verified to contain the DC-033 fix (extracted + grep'd self-updater.js — comment "Resolve package.json/VERSION relative to the api root, not __dirname" present). Live `get.dashcaddy.net/release/version.json` serves v1.14.9. SHA256 matches between local + served tarball. Local notify to localhost:3001 returned HTTP 403 (expected — DASHCADDY_UPDATE_ENABLED=false, intentional). Auto-update now ships the 0.0.0 fix to every host that updates from v1.14.8 → v1.14.9.
+
+### DC-035: Add regression test for getLocalVersion() — prevent DC-033 class from regressing
+- **status:** done
+- **owner:** krystie
+- **details:** DC-033 fixed the bug but nothing in the test suite would have caught it originally. The existing coverage on `self-updater.js` is sparse — no test exercises `getLocalVersion()` directly. Add `__tests__/self-updater-version.test.js` that: (1) `require('./src/docker/self-updater')` (matching what server.js does, NOT `require('./self-updater')` which resolves from cwd and loads the wrong file — that's a separate footgun, see DC-036). (2) instantiate SelfUpdater with minimal config. (3) call `getLocalVersion()`. (4) assert `version` is NOT `'0.0.0'` and is in semver shape (`/^\d+\.\d+\.\d+/`). (5) assert `commit` matches `/^[0-9a-f]{7,40}$/`. Optionally: parameterize to also exercise `require('./self-updater')` from `/app` cwd to verify the legacy root-copy contract still works. Effort: ~20 min. Pattern: matches DC-017's depth-2-routes-smoke.test.js (loads every module via the real path).
+- **impact:** Catches the exact class of bug DC-033 fixed, plus any future refactor that re-introduces the __dirname antipattern.
+- **result:** Added `dashcaddy-api/__tests__/self-updater-version.test.js` (6 tests, all passing). Validates: (1) module loads + exports SelfUpdater class; (2) getLocalVersion returns an object with version+commit (not null); (3) version is NOT `'0.0.0'` (the DC-033 bug sentinel); (4) version matches `/^\d+\.\d+\.\d+/` semver; (5) commit is a 7-40 char hex SHA; (6) works regardless of how the module is required. **Verified the test actually catches the bug** by temporarily reverting self-updater.js to the pre-DC-033 code (`git show 20d280f^`) — 4 of 6 tests failed with the expected `expect.toBe('0.0.0')` and `not.toBeNull` assertion errors. After restoring the fix, full suite passes: **40 suites, 1081 tests** (was 39/1075, +6 new).
+
+### DC-036: Delete dead `dashcaddy-api/self-updater.js` (root copy) — 0 runtime callers
+- **status:** done
+- **owner:** krystie
+- **details:** After DC-005 refactor (commit 283121e), there are TWO SelfUpdater implementations on disk: `/opt/dashcaddy/dashcaddy-api/self-updater.js` (md5 `79d566cc...`) and `/opt/dashcaddy/dashcaddy-api/src/docker/self-updater.js` (md5 `b3b61557...`). Both have drifted. **Zero runtime callers of the root copy** — verified by `grep -rn "require.*self-updater" dashcaddy-api/ --include="*.js"` which shows only `./src/docker/self-updater` (in server.js + src/app.js). The root copy is dead code from a prior refactor and a footgun for future contributors who edit the wrong file. Subagent flagged this independently. Fix: `git rm dashcaddy-api/self-updater.js` + verify `npx jest --passWithNoTests` still passes. Risk: very low. If a test does import it, the test itself is wrong and should be deleted or pointed at `./src/docker/self-updater`.
+- **impact:** Removes the wrong-file-edit footgun. Makes DC-035's test cleaner (only one SelfUpdater implementation to test).
+- **result:** Verified zero callers (grep + 38 test files scanned — no references to `./self-updater`). Discovered the file was actually gitignored, never committed — so `git rm` was unnecessary; plain `rm` did it. Tests: 1075/1075 still passing post-delete. Also synced `dashcaddy-api/VERSION` to `42376e2` (the DC-033 + release-bump commit) so the rebuilt container reports the right SHA. Live: `curl http://127.0.0.1:3001/api/v1/system/version` returns `{"name":"DashCaddy","version":"1.14.9","commit":"42376e2"}`.

+### DC-037: Move `/etc/dashcaddy/sites/dashcaddy-api` symlink creation into the install script
+- **status:** done
+- **owner:** krystie
+- **details:** DNS2 has the symlink manually created during this session (2026-07-05), but every other fresh DashCaddy install will hit the same `cp: cannot create directory '/etc/dashcaddy/sites/dashcaddy-api/routes': No such file or directory` failure when the first auto-update lands, because `dashcaddy-update.sh` defaults `apiSourceDir` to `${CADDY_BASE}/sites/dashcaddy-api` (= `/etc/dashcaddy/sites/dashcaddy-api`) while the actual install lives at `/opt/dashcaddy/dashcaddy-api`. Fix: add `mkdir -p /etc/dashcaddy/sites && ln -sfn /opt/dashcaddy/dashcaddy-api /etc/dashcaddy/sites/dashcaddy-api` to the install script (whichever of `dashcaddy-installer/install.sh` or `scripts/dashcaddy-install.sh` is canonical — verify which exists on a clean install). Make it idempotent (`ln -sfn`, not `ln -s`, so re-runs don't fail). Effort: ~10 min. Risk: very low.
+- **impact:** Prevents every future DashCaddy host from hitting the v1.14.4-class update failure on first auto-update.
+- **result:** Added `install_api_symlink()` to `dashcaddy-installer/install.sh`, called from `main()` right after `start_caddy` at end of Step 7. The function does `mkdir -p /opt/dashcaddy && ln -sfn "${API_DIR}" /opt/dashcaddy/dashcaddy-api` (idempotent: `-sfn` replaces stale links and does not fail on re-runs; `${API_DIR}` resolves to `/etc/dashcaddy/sites/dashcaddy-api` per the existing readonly constants at lines 23-26). The `mkdir -p /opt/dashcaddy` ensures the symlink's parent directory exists on a fresh host before `ln -sfn` runs. `bash -n install.sh` returns SYNTAX OK. The auto-updater's `DATA_SOURCE_DIR=/opt/dashcaddy/dashcaddy-api/data` and other `/opt/dashcaddy/...` defaults now resolve cleanly through the symlink on fresh installs. Existing DNS2 host is unaffected (the symlink already exists there from the manual session 2026-07-05; `ln -sfn` would replace it with the same target if re-run).

+### DC-038: Backup trigger.json + result.json in dashcaddy-update.sh — enable one-command rollback
+- **status:** done
+- **owner:** hermes
+- **details:** During the DC-033 fix, recovering from the failed v1.14.4 update required manually mv'ing `trigger.json.processing` back to `trigger.json`, manually running `start.sh`, etc. — because the backup mechanism in `dashcaddy-update.sh` (lines 318-327) only backs up code + data, not the trigger/result state. Fix: in the `backup_data_dir` function (or new `backup_update_state` function), also copy `${UPDATES_DIR}/trigger.json` and `${UPDATES_DIR}/result.json` into the versioned backup directory so rollback tooling can restore them. Effort: ~15 min.
+- **impact:** Faster incident recovery. Currently takes 5-10 manual steps to roll back a failed update; would take 1.
+- **result:** Added \`backup_update_state()\` function in \`dashcaddy-update.sh\` (idempotent, tolerates absent files + chattr +i, cleans up empty subdir). Wired into \`main()\` immediately after \`backup_data_dir()\`. Backs up \`trigger.json.processing\` + \`result.json\` into a \`update-state/\` subdir of the versioned backup. Deliberately does NOT auto-restore on rollback — the rollback handler reads a fresh trigger.json written by the operator/container; restoring the previous attempt's trigger would clobber the active rollback request. New regression test \`dashcaddy-api/scripts/test-dashcaddy-update-backup.sh\` (14 assertions across 5 groups: both-files-present, partial-present, no-files-present, idempotency, main() flow ordering) — all pass. Tests: 1214/1214. Lint: 150 warnings, all pre-existing in untouched files, zero new warnings introduced.
+
+### DC-039: Audit repo for other `__dirname + sibling-file` patterns — DC-033 class of bug
+- **status:** done
+- **owner:** hermes
+- **details:** DC-033 was caused by `path.join(__dirname, 'package.json')` in a module loaded from a subdirectory. There may be other instances of the same pattern elsewhere in `src/`. Quick grep: `grep -rn "path.join(__dirname" dashcaddy-api/src/ --include="*.js"` and review each hit. Any that join `'package.json'`, `'VERSION'`, `'.env'`, `'openapi.yaml'`, `'Dockerfile'`, or `'.license-secret'` is suspect (these all live at the api root, not in subdirectories). For each suspect match, either: (a) verify the file does exist at the expected `__dirname` location, or (b) fix it to use the api-root path. Effort: ~30 min. Risk: low. Just an audit + targeted fixes.
+- **impact:** Catches latent bugs before users do. The fact that DC-033 shipped undiscovered through multiple releases suggests this antipattern might exist elsewhere.
+- **result:** Found **and fixed** the antipattern across 10 modules in `src/`. 13 distinct `path.join(__dirname, 'foo.json')` defaults (plus the `__dirname` based `LOG_DIR`/`ERROR_LOG_FILE`) all wrote runtime state into the source tree, surviving in dev but landing in the image layer in production. Centralised resolution in `platformPaths.dataDir` (derived from `SERVICES_FILE` env when set, else `path.dirname(servicesFile)`); the 10 modules now route their `*-config.json` / `*-history.json` / `.port-locks` / `audit-log.json` / `error.log` / `.license-secret` / `.license-counter` defaults through it, preserving per-file env-var overrides. `crypto-utils.js` and `credential-manager.js` already had a multi-candidate resolver; collapsed them to a single `platformPaths.dataDir` lookup. The `host-registry` / `event-store` / `event-workers` `dataDir || path.join(__dirname, '../../data')` pattern simplified — the legacy fallback is unreachable now that `services.json` lives at `dataDir`. Also fixed a **real production bug found mid-audit**: `audit-logger.js` defaulted `AUDIT_LOG_FILE` to `/app/src/security/audit-log.json` and `logging.js` defaulted `LOG_DIR` to `__dirname` (i.e. `/app/src/utils/`), so every error-log/audit-log write was landing in the image layer — a fresh container recreate would have wiped the entire audit log. Now both flow through `dataDir` which the start.sh bind mount already points at `/app/data`. Drive-by: removed unused `readline` import in `event-workers.js`. Also fixed a **test gap** in `__tests__/public-routes-drift.test.js`: `routes/security.js` was missing from the direct-mounts list, so the `/api/v1/security/events/ingest` and `/api/v1/security/events/batch` PUBLIC_ROUTES entries (added by DC-044) were flagged as stale. Added it with `/security` prefix mapping. **Pre-existing files on the running container (`audit-log.json` 319KB, `container-stats*.json` 186MB, `workflow-history.json` 269KB, `audit-log.json` etc.) are still in the image layer** — those are lost on next recreate unless a one-time migration step runs; out of scope for this fix but flagged for a follow-up. **Tests: 1214/1214 pass, +0 failures. ESLint: 146 warnings + 4 errors — identical to baseline (no new warnings/errors introduced).** Docker container does NOT need rebuilding: the affected code paths are evaluated at boot, and `dashcaddy-api/data/` is the existing bind mount — the new defaults resolve to the same path the container already uses via env vars (`CREDENTIALS_FILE=/app/data/credentials.json`, `ENCRYPTION_KEY_FILE=/app/data/.encryption-key`, etc.), and the env vars take precedence. Self-updater picks it up on the next release bump.
+
+### DC-040: Investigate whether dashcaddy-post-deploy-patches.sh is still needed at all
+- **status:** done
+- **owner:** hermes
+- **details:** The script applies 23+ `require()` path fixes on every update (audit from `BUILD-PIPELINE-FIX.md` shows it was created to paper over `dashcaddy-api/src/` being missing from tarballs). After the build-pipeline-fix (which now ships `src/` in every tarball), most of those patches should be no-ops. If any are still applying real changes, that means the source tree has a latent bug that DC-005-era refactors missed. Run `bash scripts/dashcaddy-post-deploy-patches.sh` against a fresh checkout of origin/main (or extract the v1.14.8 tarball to a clean dir) and count how many patches actually change anything vs are no-ops. If most are no-ops, the script can either be deleted entirely (cleanest) or kept as a defensive backstop with a comment explaining its purpose has shifted to "verify src/ shipped correctly." Effort: ~45 min. Risk: medium — safer to keep as backstop with reduced scope.
+- **impact:** Clarity. The current state — "script applies 23 fixes every update but only 3-4 actually do anything" — is opaque and brittle.
+- **result:** Empirically measured against **all 4 release versions** + origin/main: v1.14.4 (broken — no src/ in tarball), v1.14.8, v1.14.9, and origin/main all produce **0 require-fixes applied** under the old script. Every patch is a no-op against every current release. Decision: **KEEP the script but repurpose it as a VERIFIER, not a patcher.** The script now performs 5 explicit checks (server.js requires correct, license-manager.js path correct, src/ directory present + non-empty + contains app.js, license-keygen.js at API root) + an informational scan of all src/ require paths. **Exits 1 if any check fails** — fails the build loudly instead of silently letting a crash-looping container reach production. Behaviour change: the OLD script would silently no-op on v1.14.4 (couldn't find src/ to patch); the NEW script reports `=== FAILED CHECKS ===` with the specific failures (e.g. `src/: directory missing — v1.14.4-class bug`). Verified against v1.14.4 tarball: old script 0 patches + exit 0, new script 2 failures + exit 1 + clear error names the v1.14.4-class bug. New regression test `dashcaddy-api/scripts/test-dashcaddy-post-deploy-verifier.sh` (17 assertions across 10 test groups including clean tree, missing server.js, broken server.js requires, missing src/, missing license-keygen.js, broken license-manager path, empty src/, missing src/app.js, absolute path resolution, non-existent API_DIR) — all pass. Tests: 1214/1214 Jest + 31 shell assertions. Lint: 150 warnings, all pre-existing in untouched files.
+
+### DC-041: Add integration test for the auto-update pipeline (trigger.json → bash → docker rebuild → health check → result.json)
+- **status:** done (commit 0b85caa, 5 scenarios / 37 assertions all green)
+- **owner:** hermes
+- **details:** The host-side updater has zero integration coverage. The recent DC-033 incident showed this whole chain is one big untested path. Build a test harness that: (1) creates a temporary directory mimicking `/opt/dashcaddy/updates/staging/dashcaddy-api` with a known-good tarball. (2) writes a `trigger.json` to a test `UPDATES_DIR`. (3) runs `bash /opt/dashcaddy/scripts/dashcaddy-update.sh` with paths overridden via env vars. (4) asserts `result.json` has `success: true` and the version matches. (5) cleans up. Effort: ~2 hours. Risk: medium — the script uses `docker build` so the test needs either Docker-in-Docker (DinD) or mocking the docker calls.
+- **result:** `dashcaddy-api/scripts/test-dashcaddy-update-integration.sh` (552 lines) commits and exits 0. Strategy: sandbox at `/tmp/dashcaddy-test-XXXXXX/opt/dashcaddy/` with `/opt/dashcaddy` path-rewritten via `sed`, mocked `docker` binary prepended to PATH, real `dashcaddy-post-deploy-patches.sh` verifier copied in, and a Python one-shot HTTP responder on port 33001 driving the health check (33001 chosen to avoid clashing with the live DashCaddy API on 3001). 5 scenarios: (1) happy-path update v1.14.8→v1.14.9 with mocked docker build/rm/run, backups, result.json; (2) v1.14.4-class broken tarball (no src/) — asserts the verifier IS invoked and DOES detect the bug ("Build should be ABORTED" in log); current `dashcaddy-update.sh` warns-and-continues on verifier failure, so this scenario asserts that observed behavior with a TODO note about closing that gap in a follow-up; (3) rollback to a pre-populated backup; (4) no trigger.json → no-op exit 0; (5) prerelease channel rejection when `ALLOW_PRERELEASE` is not set.
+- **impact:** Closes the biggest untested surface in DashCaddy. Would have caught the v1.14.4 packaging bug immediately on the next release.
+
+### DC-042: Replace null stubs in src/app.js getTailscaleStatus() with real Tailscale manager
+- **status:** done (commit d042386, deployed to DNS2, pushed to origin 2026-07-07)
+- **owner:** krystie
+- **details:** The long-standing `return null` stub at src/app.js:189 (plus 8 null fn stubs on `ctx.tailscale`) made `/api/v1/tailscale/*` and the `tailscaleAuthMiddleware` dead code. New module `src/managers/tailscale-manager.js` shells out to the host's `tailscale status --json`, parses, caches for 5 min, gracefully handles missing-CLI / tailscaled-down / malformed-JSON. Re-exports `isTailscaleIP` from network-detector.js. Wired into `src/context/index.js`. start.sh on DNS2 gets two new bind mounts: `/usr/bin/tailscale` (statically-linked Go binary) and `/var/run/tailscale/`. Tests: 41 unit tests covering installed/missing/daemon-down/cache/malformed/IPv4-vs-IPv6/all 8 peer fields/timer stubs. Suite went 1097 → 1138 tests passing.
+- **impact:** Dashboard's Tailscale card now shows real device list (8/9 online). `tailscaleAuthMiddleware`'s allowedTailnet check no longer dead code. Foundation for DC-043 share-invite flow.
+
+### DC-043: Tailscale coordination API client + admin/settings routes
+- **status:** done (committed, deployed to DNS2, verified end-to-end with real token 2026-07-07)
+- **owner:** krystie
+- **details:** Companion to DC-042. New module `src/managers/tailscale-coord.js` is the *write-side* REST client for `https://api.tailscale.com/api/v2/`. Wraps: list/get/delete devices, create/list/delete pre-auth keys, list users, get/update ACL. New `ctx.tailscaleCoord` namespace with `getClient`/`loadMetadata`/`saveMetadata`/`setApiToken`/`hasApiToken` helpers. API token is stored encrypted via existing `credentialManager` (key: `tailscale.coord.apiToken`); metadata in plaintext `tailscale-config.json`. New routes in `routes/tailscale-admin.js`:
+  - `GET    /api/v1/tailscale/settings` — returns `{configured, tailnetName, deviceCount, keyValidatedAt}`, NEVER the token
+  - `PUT    /api/v1/tailscale/settings` — validates token by pinging /devices, stores encrypted, returns sanitized
+  - `DELETE /api/v1/tailscale/settings` — wipes token + metadata
+  - `POST   /api/v1/tailscale/settings/test` — ping without saving, returns `{valid, tailnetName?, error?}`
+  - `GET    /api/v1/tailscale/admin/devices` — full device list via coord API
+  - `DELETE /api/v1/tailscale/admin/devices/:id` — revoke device
+  - `GET    /api/v1/tailscale/admin/users` — tailnet users
+  - `GET    /api/v1/tailscale/admin/keys` — pre-auth key metadata
+  - `POST   /api/v1/tailscale/admin/keys` — create pre-auth key (returns secret ONCE)
+  - `DELETE /api/v1/tailscale/admin/keys/:id` — revoke pre-auth key
+- 74 unit + route tests (45 client + 29 route integration). Suite: 1214/1214 passing.
+- **deployed to DNS2, verified:** `docker exec dashcaddy-api node ...` against the real token returned `ping: {domain: "tail3e209.ts.net", deviceCount: 9}`, `devices: 9`, `keys: 3`, `users: 3` — full field set per device (id, addresses, hostname, OS, lastSeen, nodeId, etc.).
+- **API quirk discovered mid-build:** The `/api/v2/tailnet/-/preferences` endpoint that early doc references suggested for token-validity pings was **retired by Tailscale in 2026** (returns 404 with no fallback). ping() now hits `/tailnet/-/devices` and derives the tailnet name by extracting the `*.ts.net` suffix from the first device's `name` field. Also discovered `core.worktree` confusion mid-session — git thought `/opt/dashcaddy`'s repo lived at `/root/dashcaddy`, which caused the first commit to appear "lost" until I recovered via `git reset --hard <sha>` from the reflog.
+- **intentionally NOT built:** token auto-rotation / auto-renewal. Tailscale API keys don't auto-renew, and silently re-issuing admin credentials would erode the audit-trail checkpoint that token expiry provides. If a user needs rotation, they re-paste via the UI — explicit and intentional.
+- **impact:** Foundation for DC-044 (Plex/whatever share-invite flow). With this, every DashCaddy install can manage its own tailnet from a single paste-the-key-once UI flow.
+
+---
+
+## Backlog note (2026-07-05)
+
+Tickets DC-033 through DC-041 were added after the DNS2 v1.14.4 / v1.14.8 / 0.0.0 incident. They are grounded in real evidence from that session — see DC-033's details for the full chain of reasoning (cross-checked by main agent + z.ai subagent).
+
+### DC-044: Fix WorkflowEngine healthCheckService — servicesStateManager.getState bug (silent every-5min error spam)
+- **status:** done
+- **owner:** hermes
+- **details:** `src/recipes/bundled-workflows.js:310` calls `servicesStateManager.getState()` which doesn't exist (StateManager exposes `read()`, not `getState()`). Combined with a missing `await`, the call returned a Promise (truthy), short-circuited via `|| []` to an empty array, then `for (const service of services)` silently iterated over zero services. Net effect: every `health-check-on-interval` workflow ran every 5 min, reported `Action health-check failed: servicesStateManager.getState is not a function`, sent a "Health check failed for {{serviceId}}" notification (with the unresolved template!), and produced `checked: 0, healthy: 0` results. Visible on BOTH DNS2 (production, 4 days) and test server dc-contabo-de (9 days). Fix: call `await servicesStateManager.read().catch(() => [])` — proper async + corruption-tolerant.
+- **impact:** Workflow health checks now actually check container health, instead of silently reporting 0/0 every cycle. Stops the "Health check failed" notification spam.
+- **result:** Fixed in src/recipes/bundled-workflows.js. New regression test `__tests__/bundled-workflows-health-check.test.js` — 5 cases (uses .read() not .getState(), correct counts, graceful degrade on read() throw, no servicesStateManager on ctx, single-service path). Full suite: 1219/1219 pass (+5 new).
+
+### DC-046: Pluggable AuthProvider interface — refactor TOTP into one of N providers
+- **status:** done
+- **owner:** hermes
+- **details:** Today DashCaddy has only one login method (TOTP). For a public-release product we need at least a second (email magic link), and the TOTP-only design doesn't scale — every new user needs a TOTP secret provisioned manually, no self-service recovery, no per-user audit trail. Refactor: define a `AuthProvider` interface in `src/auth/providers/` with methods `{ name, enabled, loginMethods, initiate(req) -> {redirect, challenge?}, verify(req) -> {user} }`. Move the existing TOTP code into `src/auth/providers/totp.js` as one implementation of that interface. `createApp` composes all enabled providers and exposes them via `/api/v1/auth/login` and `/api/v1/auth/login/:method` routes. Login page lists all enabled providers with their own button. Zero behavior change for existing TOTP users — the route shape becomes `/api/v1/auth/login/totp` instead of `/api/v1/auth/login`, but the existing UI is rewritten to match. Effort: ~1 hr. Risk: medium (touches the auth path that is the most security-sensitive area of the codebase).
+- **impact:** Unlocks every other auth provider (DC-047 email magic link, DC-048+ OIDC, SAML, etc.) without further refactors of the auth path.
+- **result:** Shipped. 6 new modules under `src/auth/providers/` (~1100 LOC): `base.js` (AuthProvider contract), `totp.js` (TOTP impl), `email.js` + `email-tokens-store.js` + `email-sender.js` (DC-047 email impl, included here because the registry requires both), `index.js` (createAuthProviderRegistry). New `routes/auth/login.js` (109 LOC) mounts under `/auth`. Existing `routes/auth/index.js` wires the registry + mount. `src/utilities/middleware.js` + `src/security/csrf-protection.js` PUBLIC_ROUTES + CSRF entries updated to `/api/v1/auth/login/:provider/{initiate,verify}` and `/api/v1/auth/disable/:provider` (parameterized, future-proof for OIDC/SAML). `__tests__/auth-provider-registry.test.js` (9 new tests) covers registry composition, no-secrets-leak guarantee, enabled-flag respect, dev-console fallback for the email provider. `__tests__/public-routes-drift.test.js` fixed for Express 4.22.x compat (the previous regex extraction broke on the new `^\/path\/?(?=\/|$)` source format). Tests: **1241/1241 passing across 46 suites** (was 1232; +9 new).
+
+### DC-047: EmailMagicLinkProvider — email-only login via nodemailer
+- **status:** done
+- **owner:** hermes
+- **details:** Second AuthProvider implementation, sitting alongside TOTP. **Email IS the identity — no separate username field at any point.** Flow: user enters email at `/login`, server generates a single-use token (32 random bytes, base64url), stores it in `data/email-tokens.json` with 15-min TTL, sends an email via the existing nodemailer connection in `src/managers/notification-manager.js:290` (reuse the same SMTP config — `providers.email.host/port/username/password/from`). Email body contains a link like `https://dashcaddy.example.com/auth/verify?token=abc123`. Click → server validates token (exists, not expired, not already used) → marks used → creates session cookie → redirect to dashboard. On subsequent visits, session cookie is the credential. Rate-limit the request-link endpoint to 5 per email per hour to prevent email-bombing. Tokens stored as SHA-256 hashes in the JSON store so a read-only compromise can't be used to forge links. Effort: ~3 hrs. Risk: medium (depends on SMTP creds being configured; if not, fall back to console-logging the link in dev mode).
+- **impact:** Public product readiness. Zero-password login. No username/email split — one field, one identifier. Reuses existing nodemailer config — no new dependency, no new credential surface. Works with any SMTP server Sami already uses (he mentioned using the SMTP server his website runs).
+- **prerequisite:** DC-046 (the interface to implement against).
+- **result:** Shipped as part of DC-046 commit. `src/auth/providers/email.js` (388 LOC): registers `magic-link` (initiate) + `verify-token` (verify) methods, generates 32-byte base64url tokens, stores SHA-256 hashes via `email-tokens-store.js`. `email-tokens-store.js` (260 LOC): atomic lockfile-based mutation, automatic cleanup of expired tokens, audit log on every issue/use. `email-sender.js` (67 LOC): wraps nodemailer if `providers.email` config is set, else falls back to `log.info('auth', 'email magic link issued', ...)` so dev installs work without SMTP config. Verified with stub deps: `initiate()` writes a token + logs `deliveredVia: 'dev-console'` + returns masked email; `verify('verify-token', { token: 'garbage' })` throws AuthenticationError (route handler converts to 401). Real SMTP wiring takes effect as soon as `providers.email.host/port/username/password` are set in config.json.
+
+### DC-048: Multi-user bootstrap + admin invites
+- **status:** done
+- **owner:** hermes
+- **details:** The user model shifts from "one implicit operator" to "many users with explicit roles". Bootstrap rule: the FIRST email to ever successfully log in via email magic link becomes the admin. Subsequent emails are denied with a `not authorized` error UNLESS the email appears in `data/authorized-users.json`. Admin UI: a `/users` page that lists authorized users, lets admin add emails (manual entry) or generate single-use invite links (which work like magic links but pre-add the email to the allowlist on first use). Audit log gets `userEmail` attribution on every entry. License model is unchanged (still per-host) but note in the ticket that this may need revisiting. Effort: ~2 hrs. Risk: low (mostly UI + JSON-store CRUD).
+- **impact:** First real multi-user DashCaddy. Per-user audit attribution. Self-service invites. Foundation for any future "team" features.
+- **prerequisite:** DC-047 (needs email auth working first).
+- **result:** Shipped as opt-in. Email auth must be explicitly enabled via `siteConfig.authProviders.email.enabled = true`; single-user TOTP-only installs see zero behavior change. New modules: `src/security/user-store.js` (users + allowlist + bootstrap sentinel, atomic writes, last-admin protection, 380 LOC), `src/security/invite-store.js` (single-use tokens, SHA-256 hashed on disk, TTL, 230 LOC). New routes: `routes/auth/admin.js` (`/me`, `/admin/users` GET/POST/PATCH/DELETE, `/admin/allowlist`, `/admin/invites` GET/POST/DELETE, public `/invites/:token` peek + `/invites/:token/accept` redeem, 360 LOC). EmailMagicLinkProvider `verify()` calls `userStore.isEmailAuthorized()` then `userStore.login()` then tags `req.user` for audit attribution; TOTP `verify()` bootstraps a `system@totp.local` admin record on first login so the current operator shows up in `/admin/users` without a re-login. Audit logger middleware reads `req.user` and adds `userId`/`userEmail`/`userRole`/`viaProvider` to log details. New admin UI: `status/js/admin.js` (modal overlay, users list with role-edit + delete, invite form with copy-link button, outstanding-invites list with revoke). Wired into `core/init.js` so the "Admin" trigger button appears in the top bar only when `/me` returns `isAdmin: true`. 35 new tests across 3 files. Full suite: 1298/1298. Update PUBLIC_ROUTES + CSRF allowlists for the new invite redemption paths (same exemption rationale as login verify).
+
+### Backlog note (2026-07-20, hermes)
+
+DC-046 + DC-047 landed together in one commit because the registry requires both implementations to be loaded at startup — splitting them would mean a half-broken registry at the intermediate commit. The commit message documents both IDs.
+
+DNS2 deploy: code change + `scripts/publish-release.sh` + `docker build` + `bash start.sh` + live verify. After this lands, `/api/v1/auth/login/methods` returns both `totp` and `email` providers for any host with email-magic-link enabled. Hosts without SMTP configured fall back to the dev-console path so end-to-end testing works before production SMTP is provisioned.
+
+Sami explicitly stated he wants email auth as an OPTION alongside TOTP, not a replacement — TOTP remains his primary method for personal/network-only access, email magic link is for public-product readiness. Architecture choice: `AuthProvider` interface in `src/auth/providers/` so future methods (OIDC, SAML, passkeys) plug in without further refactors. SMTP delivery reuses the existing `nodemailer` integration in `src/managers/notification-manager.js:290` — no new dependency. Sami plans to use the SMTP server his website runs (sami-ahmed.net) so the host field will be configurable.
+- **details:** The user model shifts from "one implicit operator" to "many users with explicit roles". Bootstrap rule: the FIRST email to ever successfully log in via email magic link becomes the admin. Subsequent emails are denied with a `not authorized` error UNLESS the email appears in `data/authorized-users.json`. Admin UI: a `/users` page that lists authorized users, lets admin add emails (manual entry) or generate single-use invite links (which work like magic links but pre-add the email to the allowlist on first use). Audit log gets `userEmail` attribution on every entry. License model is unchanged (still per-host) but note in the ticket that this may need revisiting. Effort: ~2 hrs. Risk: low (mostly UI + JSON-store CRUD).
+- **impact:** First real multi-user DashCaddy. Per-user audit attribution. Self-service invites. Foundation for any future "team" features.
+- **prerequisite:** DC-047 (needs email auth working first).
+
+### DC-049: Update login UI to show multiple providers
+- **status:** done
+- **owner:** hermes
+- **details:** Currently the login page is TOTP-only. Once DC-046/047/048 ship, login needs to render ALL enabled providers as a list of buttons, each routing to its provider-specific initiate flow (`/api/v1/auth/login/totp`, `/api/v1/auth/login/email`). Frontend work — `status/js/core/login.js` and the login modal markup. Add a small "Choose how to sign in" header. Effort: ~1 hr. Risk: low (pure UI, no backend changes).
+- **impact:** Makes the pluggable auth provider pattern visible to users. Without this, providers other than TOTP are unreachable.
+- **prerequisite:** DC-046 + DC-047 (needs at least two providers to be meaningful).
+- **result:** Shipped. New module `status/js/auth-gate.js` (~290 LOC) owns the `?auth=required` flow: queries `GET /api/v1/auth/login/methods`, renders one of three UIs — provider selector (2+ enabled), TOTP overlay + email fallback link (only TOTP enabled, email available), or pure legacy TOTP (truly single-provider). `email` provider renders inline: text input + "Send sign-in link" button that POSTs to `/api/v1/auth/login/email/initiate`; on success shows the masked recipient + deliveredVia ('dev-console' vs 'inbox'). Coordination with `totp-auth.js`: `auth-gate.js` sets `window.__dc_049_handled = true` at IIFE entry so the legacy TOTP module skips its own UI when auth-gate is in charge, eliminating flicker on multi-provider installs. Bundle order in `build.js`: auth-gate BEFORE totp-auth (flag must be set first). Verified live: `https://status.sami/dist/core.js` contains all 4 expected markers (`_showAuthGate`, `provider-btn`, `auth-gate-email-input`, `__dc_049_handled`). SW cache hash `dashcaddy-shell-c550d0b371` (was `dashcaddy-shell-310b97d25a` before this work). User instruction: hard-refresh `status.sami` to pick up the new bundle.
+
+### DC-050: Harden platform-paths.dataDir — structural guard against image-layer data loss
+- **status:** done
+- **owner:** hermes
+- **details:** DC-039 audited and fixed every module that defaulted `path.join(__dirname, 'foo.json')` — the audit-logger, license-keygen, credential-manager, port-lock-manager, resource-monitor, log-digest, update-manager, and crypto-utils all now route through `platformPaths.dataDir`. Verified live on DNS2: the live audit log at `/app/data/audit-log.json` is 315 KB and being actively written; the vestigial `/app/src/security/audit-log.json` is 2 bytes (Jul 6) and never written to post-fix.
+- **What was left undone (now fixed):** the structural guard. `platformPaths.dataDir` resolved via `path.dirname(SERVICES_FILE)`. If `SERVICES_FILE` env was unset (e.g. operator deletes the -e flag from start.sh), the fallback chain went `path.join(CADDY_BASE, 'services.json')` → `/etc/dashcaddy/services.json` → dataDir = `/etc/dashcaddy`. That's the IMAGE LAYER on Docker. **Audit-log + license-secret + error.log would silently land there and vanish on every container recreate.** Same failure shape as DC-039, but a different code path.
+- **Fix (three parts):** (1) `platform-paths.assertSafe({ mode })` — throws a clear FATAL in production mode if dataDir resolves into any of 11 forbidden zones (`/app/src`, `/app/routes`, `/app/scripts`, `/app/utils`, `/app/managers`, `/app/security`, `/etc`, `/etc/caddy`, `/etc/dashcaddy`, `/usr`, `/usr/local`, `/var`, `/var/lib/caddy`). Calls a second predicate `isMountedCheck(dir)` that returns false for non-writable or non-existent dirs (Windows warning, not throw). Bypassed with `SKIP_DATA_DIR_GUARD=1`. (2) `server.js:35` — calls `assertSafe` before any other startup work. Refuses to boot loudly instead of running with a path that loses data silently. (3) `start.sh:13-66` — one-time migration step runs before `docker run`. Scans 6 known image-layer zombie paths (`/opt/dashcaddy/dashcaddy-api/src/{security,utils,managers}/*`), copies any non-empty content to `${DATA_DIR}/migrated-*`, gates one-shot with a sentinel file `.migrated-from-image-layer`. Idempotent. Survives `set -e` per-file failures. Per-file `cp -a` guarded so a single unreadable zombie can't take the container down. Will recover the 140 KB `error.log` that the live DNS2 container has in its image layer (timestamp Jul 6 — pre-DC-039 era).
+- **result:** 19/19 platform-paths tests pass (8 new for assertSafe + 3 new for isMountedCheck). 5/5 start.sh migration tests pass (sentinel-skips, file-copies, idempotent-no-clobber, empty-file-skip, set-e-survives-failure). DNS2 deploys unchanged except for the new migration step running once on next recreate. Suite overall: 1066/1067 (one pre-existing public-routes-drift failure from in-flight Track A code, untouched).
+
+### DC-052: License-tier enforcement — Free caps user count at 3, gates share features on Pro
+- **status:** done
+- **owner:** hermes
+- **details:** Per `/root/dashcaddy/PRODUCT-SPEC-DECISIONS.md` (locked 2026-07-20): Free = up to 3 users, Pro = unlimited. The DC-048 user-store needs a `countUsers()` helper. The `/api/v1/auth/admin/invites` POST handler must check `if (users.count() >= 3 && !licenseManager.isPro()) throw new ValidationError('upgrade required', 'tier')`. Same check on `POST /admin/users` (pre-authorize). Share-link creation routes (DC-053) gate on `licenseManager.isPro()`. **Free has NO trial path** — there is no automatic Pro trial, no time-limited upsell. The user picks Free or Pro deliberately. **LIFETIME keys are creator-only**: the API rejects any LIFETIME code at `verifyCode` time in production. The `license-keygen.js --lifetime` path stays on Sami's dev machine only; it's never wired to Stripe Checkout.
+- **impact:** First pricing enforcement. Without this, Pro is just a label. With this, every upgrade path has a clear moment to upsell.
+- **prerequisite:** DC-048 (shipped).
+- **result:** Audited the implementation already present in commit `273f6b8` (the backlog status was stale). `user-store.js` exposes atomic `countUsers()`. Auth admin routes enforce the 3-user Free cap on both `POST /admin/users` and `POST /admin/invites`, returning `PaymentRequiredError` (402) before creation; invite acceptance also enforces the cap. Share creation is Pro-gated in DC-053. `LicenseManager.activate()` rejects lifetime codes unless `ALLOW_LIFETIME_LICENSE=true`, preserving creator-only lifetime keys. Existing regression suite `license-tier-enforcement.test.js` covers the cap, Pro bypass, invite gate, lifetime behavior, and count/delete semantics. Full Jest baseline and post-audit: **52 suites, 1372 tests passed**. ESLint reported 180 existing problems (including 4 existing errors); no source files were changed in this audit, so no new lint issues were introduced.
+
+### DC-053: Public share links + Tailscale-mediated share — Pro-gated
+- **status:** done
+- **owner:** hermes
+- **result:** Shipped as `PROD` commit (this session). Share-store (`src/security/share-store.js`) + share-routes (`routes/share.js`) + 53 tests (24 store + 29 routes, full suite 1372/1372). Public endpoints CSRF-exempt (token IS proof); admin POSTs gated on `licenseManager.isPro()` → 402 PaymentRequired on Free. Tailscale path mints single-use ephemeral pre-auth key, emails join link, rolls back the share record if `tailscaleCoord.createAuthKey()` throws so no orphans leak. Email-delivery failure path exposes raw `urlPath` so admins can manually deliver when SMTP is down. Drift-test parser hardened against quoted-word comments. Public-route drift test registers `routes/share.js` with a real-shape shareStore stub so the router walker enumerates the share paths. **UI side still pending** — no "Share" button on service cards yet, modal not built (admin can still exercise via curl).
+- **details:** Two new feature surfaces behind a Pro license check. (1) **Public share links** — `POST /api/v1/share` creates a signed URL (e.g. `https://status.sami/share/<token>`) for a specific service + a TTL (1h/24h/7d). The share page renders a read-only preview: service metadata + a `subscribe` button that hits `/api/v1/share/:token/subscribe` to register the visitor's email for updates. (2) **Tailscale-mediated share** — `POST /api/v1/share/tailscale` generates a Tailscale pre-auth key (one-shot, single-use, 24h) scoped to a specific device tag, emails the link to the invitee; clicking it joins them to the host's tailnet and proxies them to the service. Both surfaces gated on `licenseManager.isPro()` (DC-052). UI: a "Share" button on each service card, modal with the two tabs.
+- **impact:** The killer Pro feature. "Share your services with anyone, they don't even need a Tailscale account" — that's the pitch. Without this, Pro has no upgrade pull.
+- **prerequisite:** DC-042 + DC-043 (Tailscale manager + coord API shipped); DC-052 (license check); DC-048 (invite flow model).
+
+### DC-054: License-keygen CLI improvements + Stripe webhook bridge script
+- **status:** done
+- **owner:** hermes
+- **result:** Shipped (verified 2026-08-23 autonomous-fixer audit). All three deliverables exist on main: (1) `--tier` flag in `license-keygen.js` (cosmetic pro label + forward-compatible hook for a future tier that alters generation); (2) `scripts/stripe-license-bridge.js` (webhook listener reading `STRIPE_WEBHOOK_SECRET`, exported `createServer()` factory for tests); (3) validation path body unchanged since the 2026-07-25 keygen refactor — the only keygen change since is the documented `LICENSE_SECRET_FILE` env-var override for secret-file location, which does not touch `verifyCode()` (git diff 592a9fd..HEAD confirms verifyCode absent from the diff). Test coverage: `__tests__/billing/` — `stripe-license-bridge.test.js`, `bridge-lookup-http.test.js`, `e2e-billing-flow.test.js`, `invoice.test.js`. **Fresh rerun 2026-08-23: 8/8 billing suites, 131/131 tests green; focused signature-verification tests 3/3 (rejects missing sig / wrong sig / out-of-tolerance timestamp); evidence captured at main HEAD `09d56fd`.** Later extended by DC-058 (commit `e8ab0e0`, mm-grade=A: Stripe license + invoice email automation). Note the SKU contract was subsequently superseded by DC-057's canonical `metadata.productId` catalog — bridge consumers should read DC-057's result, not this ticket's original SKU wording.
+- **details:** Existing `dashcaddy-api/license-keygen.js` already supports durations [30, 90, 180, 365]. Three additions: (1) `--tier pro` flag (currently `--duration 30/90/180/365` — duration alone implies Pro, so the flag is just for CLI clarity). (2) `dashcaddy-api/scripts/stripe-license-bridge.js` — listens on `STRIPE_WEBHOOK_SECRET`, validates `checkout.session.completed` events, looks up the duration by SKU ID, generates a license key, emails it to the customer, returns `{delivered: true}` to Stripe. (3) `dashcaddy-api/license-keygen.js` validation path — already exists, no change. Sami generates initial keys via CLI for the launch.
+- **impact:** Closes the loop between Stripe payment and license-key delivery. Without this, every sale requires manual key generation by Sami.
+- **prerequisite:** None. Stripe-side can be set up in parallel with DC-052.
+
+### DC-055: dashcaddy.net/pricing static page + Stripe Checkout integration
+- **status:** in-progress
+- **owner:** hermes
+- **details:** Static page at `/pricing` showing the 5-row tier table (Free / 1mo / 3mo / 6mo / 12mo). Stripe Checkout button per paid tier. On success, the page reveals the license key with copy-button + "Here's how to install it" link. Receipt email sent via Stripe's built-in. No account creation in this flow (Q10 decision — optional dashcaddy.net account is post-v1.0).
+- **impact:** The conversion surface. Without this, the product is real but unsellable.
+- **prerequisite:** DC-054 (Stripe webhook bridge so licenses auto-issue).
+- **result:** **Partially shipped — live surfaces verified, end-to-end payment flow NOT yet evidenced. Verified live 2026-08-23T07:18Z (autonomous-fixer audit):** the conversion surface now lives on the dedicated Next.js marketing site `dashcaddy.net` (source `/root/dashcaddy.net/`, static export deployed to Samihost `194.163.161.162:/home/dashcaddy.net/public_html/`, DNS confirmed via getaddrinfo → 194.163.161.162; DNS2's `/home/dashcaddy.net/public_html/` is empty — DNS2 does not serve it). `https://dashcaddy.net/pricing` → 308 → `/pricing/` 200 (39962B, 30/90/180/365-day pickers, one-time + subscription modes, "Secure checkout via Stripe"); `https://dashcaddy.net/success/` 200 (client-side poll of `licenses.dashcaddy.net/api/checkout/session/:id`, license-key reveal + pending_email fallback in `src/app/success/page.tsx`); `https://licenses.dashcaddy.net/health` → 200 `{"ok":true,"service":"dashcaddy-license-server"}`. Plan codes (license server `plans.js`): premium_30d $20 / premium_90d $50 / premium_180d $70 / premium_365d $99. Earlier work: public-routes-drift half (commit 86df178, grade A) + DC-057 checkout→license contract (9b9711b, grade B; billing suites fresh-rerun 2026-08-23 at main HEAD `09d56fd`: 8/8, 131/131 green). **NOT verified (blocks done):** an end-to-end Stripe test-mode transaction — checkout-session creation → redirect → signed webhook fulfillment → persisted license → session lookup → success-page reveal (or documented email fallback). Static page text + health endpoint do not substitute. Codex judge held the done-transition on exactly this (verdict urn:ump:tqw6pvgj576f73ubhzff77sccm7azjyyg67o4z346yk45swgjleq). Also open: the superseded in-repo `status/pricing/index.html` (served by the status.sami SPA catch-all, 0 stripe refs) is dead weight — cleanup candidate.
+
+### DC-057: Close checkout-to-license contract drift before public billing launch
+- **status:** done
+- **owner:** hermes
+- **details:** Codex audit found the current Stripe checkout and webhook bridge cannot interoperate: `dashcaddy-api/src/billing/stripe-client.js` emits `metadata: {tier, period, product}` while `dashcaddy-api/scripts/stripe-license-bridge.js` requires `metadata.sku`, so every paid Checkout completion returns `unknown-sku` and no license is delivered. The locked product decisions define one-time 30/90/180/365-day licenses at $20/$50/$70/$99, while the current pricing page and billing client present monthly/annual subscriptions. The product spec promises a license key on the success page, while the current page only redirects to Checkout and documents email-only delivery. The bridge comments and implementation also disagree about whether email failures are recorded for retry/idempotency.
+- **impact:** Current billing can accept payment without issuing a license, which blocks public release and risks paid-customer support incidents.
+- **prerequisite:** DC-054 and DC-055 working-tree billing artifacts are present but not yet released as a coherent, verified flow.
+- **acceptance:** Define one canonical paid-product catalog shared by Checkout, webhook fulfillment, tests, and pricing labels; use the locked USD prices and one-time payment/duration semantics; feed the exact Checkout metadata into the bridge in a cross-module contract test; make duplicate/retry events unable to issue two keys; persist a recoverable license before email delivery and provide an explicit, tested SMTP-failure recovery path; reconcile success-page behavior, one-license-per-host wording, and legal/product copy with the actual secure delivery mechanism.
+- **result:** Codex grade B. 1498/1498 Jest tests pass (62 suites), zero new ESLint warnings introduced. Shipped as one coherent DC-057 commit (no partial worktree artifacts). Single canonical product catalog (`src/billing/catalog.js`) shared by Checkout client, webhook bridge, pricing page, and catalog-consistency test. Stripe Checkout rewritten for **one-time payment** keyed by `productId` (`pro-30d`/`pro-90d`/`pro-180d`/`pro-365d`) at $20/$50/$70/$99, with `metadata.productId` as the single contract feeding the bridge — no SKU drift possible. Webhook bridge now requires `payment_status === 'paid'` before fulfillment (rejects unpaid/no_payment_required/missing with ack 200) and handles the ACH/SEPA delayed-payment flow via `checkout.session.async_payment_succeeded`. License is persisted to the durable fulfillment-store **before** email delivery; on SMTP failure, the lookup endpoint serves the persisted code in `pending_email` state (the documented recovery path) so the customer can save it manually. Layer-1 (event-id-keyed) and layer-2 (session-id-keyed) idempotency prevent duplicate issuance — a second webhook for the same Checkout Session ID reuses the persisted code, never generating a second key. Stripe Checkout return URLs are derived from `STRIPE_PUBLIC_ORIGIN` env var or `STRIPE_ALLOWED_HOSTS` allowlist (not raw `Host` header) — closes the host-header-poisoning + session-ID-leak class of attack. New success page (`status/billing/success.html`) reveals the license key with a copy button and polls the lookup endpoint every 1.5s. New test files: `stripe-license-bridge.test.js` (24 tests — signature, parsing, catalog resolution, idempotency, SMTP recovery, async payment events, lookupSession), `billing-lookup.test.js` (8 tests — HTTP-level route coverage of `/api/v1/billing/lookup/:sessionId` via real Express server), `bridge-lookup-http.test.js` (5 tests — bridge's own `/lookup/:sessionId` HTTP endpoint, uses exported `createServer()` factory so the SAME dispatcher the production server uses is exercised), `pricing-page-catalog.test.js` (9 tests — enforces consistency between catalog and the hardcoded pricing page at the per-tier level, plus success-page existence + lookup-endpoint reference), `checkout-origin.test.js` (6 tests — covers `STRIPE_PUBLIC_ORIGIN`, `STRIPE_ALLOWED_HOSTS`, host-header injection rejection, javascript: scheme rejection, http:// in production rejection). All 3 stale test files from the rolled-back DC-055 attempt removed (`__tests__/stripe-license-bridge.test.js`, `__tests__/routes/billing.test.js`). Bridge code refactored: `handleWebhook` decomposed into `verifySignature` + `parseEventBody` + `checkEventIdempotency` + `fulfillCheckout` + `ensureLicensePersisted` step functions (under ESLint complexity=20 cap). Production server created via exported `createServer()` / `createRequestHandler()` factories guarded by `require.main === module` so test imports don't leak an HTTP server. Pricing page (`status/pricing/index.html`) rewritten as 4 hardcoded tier cards with `data-product-id` attributes; old monthly/annual subscription toggle removed. Success page (`status/billing/success.html`) new — copy-button reveal, 1.5s polling, TTL-aware messages. To deploy: set `STRIPE_PRICE_PRO_30D/90D/180D/365D` env vars + `STRIPE_PUBLIC_ORIGIN=https://status.sami` (or set `STRIPE_ALLOWED_HOSTS=status.sami` for header-based fallback); configure the Stripe webhook endpoint to point at the bridge's `:3010/webhook` URL with the bridge's `STRIPE_WEBHOOK_SECRET`. Deploy the new pricing + success pages to `/var/www/dashcaddy-status/`. Bridge runs as `scripts/stripe-license-bridge.js` on port 3010.
+
+### DC-056: ToS + Privacy Policy pages — GDPR-aware, no SOC2/HIPAA for v1.0
+- **status:** done
+- **owner:** hermes
+
+### DC-061: Remove superseded status/pricing/index.html — dead weight since dashcaddy.net pricing page
+- **status:** done
+- **owner:** hermes
+- **details:** The in-repo `status/pricing/index.html` was served by the status.sami SPA catch-all but duplicated the canonical pricing page now living on the dedicated Next.js marketing site at `dashcaddy.net/pricing`. It had 0 Stripe refs in the current codebase (the marketing site handles checkout). Removed the file and its parent directory. Also deleted the obsolete test `__tests__/billing/pricing-page-catalog.test.js` that validated the now-removed page against the catalog — pricing-page/catalog consistency is now verified by the dashcaddy.net marketing site's own test suite. No Caddy config change needed — the SPA fallback serves index.html for /pricing, which is correct behavior (dashboard app handles unknown routes).
+- **result:** Removed `status/pricing/index.html` and `status/pricing/` directory. Deleted `__tests__/billing/pricing-page-catalog.test.js` (9 tests). All 2854 remaining tests pass, zero new ESLint warnings.
+- **details:** Two static pages at `/legal/tos` and `/legal/privacy`. ToS covers: license terms (per-host, non-transferable), prohibited use, refund policy (pro-rated refunds within 14 days of initial purchase), termination. Privacy Policy covers: data collected (license key, host metadata, optional email), data NOT collected, third parties (Stripe — payment, Tailscale — coord API calls only when operator configures it), GDPR rights (access, deletion, portability — even though we have no central account system, we'll respond to direct requests within 30 days). No SOC2/HIPAA — that's a v2 conversation.
+- **impact:** Legal compliance for taking money. Stripe can technically sell without these but payment processors flag accounts without them.
+- **prerequisite:** None.
+- **result:** Added responsive Terms and Privacy HTML at `status.sami/legal/{terms,privacy}`, a `tos` meta-refresh redirect to `terms`, dashboard footer links, and a DNS2 deploy script that rsyncs to `/var/www/dashcaddy-status/legal/` then validates each URL via curl. Terms apply the launch requirement of pro-rated refunds within 14 days. Single canonical host (status.sami) — the aspirational `legal.dashcaddy.net` is deferred to a v1.x deploy when DNS+Caddy vhost+LE cert infra is in place.
+
+### Backlog note (2026-07-14)
+
+Tickets DC-046 through DC-049 implement pluggable auth + email magic link. Sami explicitly stated he wants email auth as an OPTION alongside TOTP, not a replacement — TOTP remains his primary method for personal/network-only access, email magic link is for public-product readiness. Architecture choice: `AuthProvider` interface in `src/auth/providers/` so future methods (OIDC, SAML, passkeys) plug in without further refactors. SMTP delivery reuses the existing `nodemailer` integration in `src/managers/notification-manager.js:290` — no new dependency. Sami plans to use the SMTP server his website runs (sami-ahmed.net) so the host field will be configurable. Total estimated effort: ~7 hrs, can ship in any order DC-046 → DC-047 → DC-048 → DC-049, but DC-046 is the foundation.
+
+### DC-045: Fix WorkflowEngine init — `new (require(...))()` precedence bug on ES6 classes
+- **status:** done
+- **owner:** hermes
+- **details:** server.js:93 (v1.13.4) instantiated `new (require('./src/managers/notification-manager'))({...})`. V8 parses this as `(new (require('./x')))(opts)` — which invokes the module's exported class AS A FUNCTION (without `new`), triggering `Class constructor NotificationManager cannot be invoked without 'new'` at server startup. Result: workflow engine never initializes on the running test server (dc-contabo-de). Combined with DC-044 (the .getState bug), the workflow feature has been broken since at least v1.13.4 and visible on both DNS2 + test server.
+- **impact:** Workflow engine now starts cleanly. Health-check-on-interval workflow now actually runs against real services instead of silently 0/0.
+- **result:** Hoisted `const NotificationManager = require(...)` and used `new NotificationManager({...})` in the server.js init block. Verified live on dc-contabo-de: workflow engine now logs `Workflow engine initialized` on startup; 90s of post-restart logs show zero `getState is not a function` errors, zero `WorkflowEngine Action health-check failed` spam, zero error-priority entries. Health check: 200 OK with uptime reporting.
+
+### DC-058: Share UI — admin modal + public preview page (completes DC-053)
+- **status:** done
+- **owner:** hermes (graded B by codex-as-judge)
+- **details:** DC-053 shipped the full share backend (share-store + 8 routes, 53 tests, Pro tier-gate, Tailscale coordination, email delivery). The `BACKLOG.md` result explicitly says: "**UI side still pending** — no 'Share' button on service cards yet, modal not built (admin can still exercise via curl)." Two missing UI surfaces: (1) **Admin share modal** — a "Share" button on each service card (next to the existing options/delete buttons in `status/js/core/grid.js:264-281`) that opens a modal with two tabs: "Public link" (1h/24h/7d TTL picker → POST `/api/v1/share` → show returned URL with copy button + revoke list) and "Tailscale invite" (email input → POST `/api/v1/share/tailscale` → show delivered status + fallback URL on SMTP failure). Modal should also list outstanding shares for the service (GET `/api/v1/share`) with revoke buttons. (2) **Public share preview page** at `/share/:token` — standalone HTML (similar to `status/pricing/index.html` and `status/billing/success.html`) that hits GET `/api/v1/share/:token/preview`, renders service metadata + an "email me when status changes" subscribe form (POST `/api/v1/share/:token/subscribe`). The URL path is already returned by the issue endpoints as `urlPath` (e.g. `/share/<token>`) — the public-preview page just needs to live at that route. Zero Pro gating on the public page (only the admin modal needs Pro check, since issuing shares is Pro-only). Effort: ~2 hr. Risk: low — the API contract is fully tested.
+- **impact:** Closes the gap between the public sale surface (DC-057 pricing page) and the Pro feature it sells (DC-053 share API). Without this UI, paying customers have no way to actually use the feature they paid for. Manual `curl` is not a UX.
+- **prerequisite:** DC-053 (shipped). DC-052 (Pro gate, shipped).
+- **result:** Shipped codex-graded B. Admin modal (status/js/share-modal.js, 382 LOC, in features.js bundle) opens via the new share button on each service card (added in status/js/core/grid.js, gated on s.id !== internet same as siblings). Two tabs: Public link (1h/24h/7d TTL picker -> POST /api/v1/share) and Tailscale invite (email -> POST /api/v1/share/tailscale). Modal lists outstanding shares (GET /api/v1/share) with revoke buttons. 402 -> Pro upgrade prompt. 400 (no Tailscale) -> setup prompt. Public preview page (status/share/index.html, 253 LOC) extracts the token from /share/<token> URL path, fetches GET /api/v1/share/<token>/preview, renders service metadata + health badge + Open service CTA. For Tailscale shares, the CTA points to the service URL (the share token is the credential -- Caddy forward_auth checks the share store on each request, so no client-side redemption is needed). Subscribe form posts to /api/v1/share/<token>/subscribe. Caddy route required: DNS2 needs a rewrite /share/* /share/index.html rule to serve the page for any /share/<token> URL. Frontend tests: 3 new node --test files (status/tests/share-modal.test.js, share-preview.test.js, core-grid-share-button.test.js) covering IIFE registration, idempotency, DOM contract, callable openShareModal, source syntax check, public preview endpoint contracts, and the regression guard for the original bug codex flagged (redeem-tailscale must NOT be called from the client -- redemption is server-side). Total: 26 frontend tests pass (was 8 + 4 share-modal + 9 share-preview + 5 grid-button). 1498/1498 backend tests still pass; zero new ESLint warnings. Codex also flagged the original redeem-tailscale placeholder as a critical bug (JS fabricating random deviceIds and silently consuming the one-shot share) -- the redesigned page now leaves redemption entirely to the server.

+### DC-059: Joi validation library — schema-based body validation middleware
+- **status:** done
+- **owner:** hermes
+- **details:** Backend uses ad-hoc `if (!field) throw new ValidationError(...)` checks at every route entry point — 49 such checks across the codebase. They drift from the field semantics, allow unknown keys to flow through, and have no way to express structured types (CIDR, enum, port range). Tracked in `DC-PRODUCTION-GRADE-BACKLOG.md` as P1-1. Fix: `npm install joi@^18`, add `src/utilities/validate.js` exporting `validateBody(schema)` middleware factory + `schemas` object with reusable schemas. Apply to destructive routes: backups (schedule/restore/config), apps (deploy/restore/revert), assets (upload/logo). Add `__tests__/unit/validate.test.js` covering each schema's accept/reject/strip-unknown behaviour. Effort: ~2 hr.
+- **impact:** Closes P0-3 / P0-4 class of bugs at the schema layer instead of per-route. Prevents future routes from accepting arbitrary body fields. New routes copy-paste from `schemas.*` and get free validation.
+- **prerequisite:** None.
+- **result:** Shipped codex-graded B. New module `src/utilities/validate.js` (170 LOC) with `validateBody(schema, opts)` middleware + 9 Joi schemas. Every exported schema has direct unit tests (41 tests total) covering middleware semantics (not just `schema.validate`). Applied to 8 destructive routes: backups (schedule/restore/config), apps (deploy/restore/revert), assets (upload/logo). Key fixes during codex review: (1) IPv6 CIDR regex was permissive (accepted `::::/64`) — replaced with Joi's authoritative `string().ip({cidr: 'required'})`. (2) appRestore empty-body semantics broke under middleware `stripUnknown` default — replaced `Joi.object({}).max(0)` with `Joi.any().custom()` that enforces non-empty rejection even after strip. (3) appDeploy.config now uses `.unknown(true)` to preserve template-specific fields (`sslType`, `dnsType`, `plexClaimToken`) that the live frontend posts — without this, deployments would silently break. Removed redundant manual `appId` check in /backups/schedule and unused `mime` destructure in /assets/favicon. Duplicate legacy `/backups/schedule` handler (pre-existing) marked LEGACY with TODO note (Express only matches first registration). 1539/1539 Jest tests pass (was 1498, +41 new). ESLint warnings unchanged (416 total, all pre-existing).
+
+### DC-060: Console→logger sweep for `src/managers/update-manager.js` (49 sites)
+- **status:** done
+- **owner:** hermes
+- **details:** Production code uses `console.log/warn/error` with `[UpdateManager]` prefixes in 49 places — these go to stdout/stderr directly, bypassing the unified logger (no structured JSON, no error.log file writes, no log-level filtering, no test capture). Tracked in `DC-PRODUCTION-GRADE-BACKLOG.md` as P1-2. Fix: import `log` from `../utils/logging`, replace every `console.log('[UpdateManager] X')` with `log.info('update', 'X')` (dropping the redundant `[UpdateManager]` tag), every `console.warn(...)` with `log.warn('update', ...)`, every `console.error('...', err.message)` with `log.error('update', err)` (passing the error object so it lands in error.log with stack + context). For mixed-content strings like `Stored old image digest: ${oldImageDigest.substring(0, 40)}...` extract the variable into the meta payload: `log.info('update', 'Stored old image digest', { digestPrefix })`. Effort: ~30 min. Risk: very low — pure logging refactor, no behavior change.
+- **impact:** Update manager events now flow through the same log pipeline as every other module: structured JSON in prod, pretty-printed in dev, error.log rotation for errors, log-level filtering, test capture via stderr spy. Operators get consistent log format and can grep across modules.
+- **prerequisite:** None.
+- **result:** Shipped codex-graded A. All 49 `console.*` sites in `src/managers/update-manager.js` now route through `log.info/log.warn/log.error` from `src/utils/logging` (tag = `'update'`). Mixed-content strings extracted into structured meta payloads (`containerName`, `schedule`, `imageName`, `error.message`, `digestPrefix`, `oldImageIdPrefix`, `httpStatus`, `maxAttempts`, `attempt`, `durationMs`, `scheduledTime`, etc.) so fields are queryable instead of inlined into the message. Errors now go through `log.error(ctx, errObj)` so they land in error.log with full stack trace + context, not just stderr. 1539/1539 Jest tests pass (78/78 update-manager tests still pass). ESLint: 14 pre-existing warnings in this file unchanged, zero new warnings introduced (verified with `git stash` baseline check).

+
+### DC-086: Service-status flicker fix — asymmetric hysteresis on the badge
+- **status:** done
+- **owner:** hermes
+- **details:** Dashboard service badges perpetually flip between green and red for "a few seconds at a time, never stable" (Sami's report, 2026-08-20). Root cause: `src/monitoring/health-checker.js` `recordStatus()` emits `'status-check'` on EVERY probe (every 30s), and `src/websocket/dashboard-ws.js` forwards every probe as `'status-change'` to the browser with no diff. The frontend `live-events.js` then unconditionally calls `setBadge()` — which resets the icon + pill text on every event. A single transient 5xx (Caddy reload, container CPU steal, mid-flight TLS handshake, container restart during probe) flips the badge red and the next green probe flips it back. Fix: add asymmetric hysteresis in `_computeDisplayedStatus(serviceId, rawStatus)` — going DOWN requires 2 consecutive "down" probes (default `HEALTH_DOWN_THRESHOLD=2`), going UP requires only 1 (default `HEALTH_UP_THRESHOLD=1`). History + `consecutiveFailures` still record raw probe results (operators want full fidelity for postmortems); only the dashboard broadcast is filtered. `getCurrentStatus()` now returns the displayed status so a page reload shows the same badge as the live SSE stream. Both thresholds are env-var configurable so operators can tune. New tests in `__tests__/health-checker-hysteresis.test.js` cover: first probe emits; second probe same-status does NOT re-emit; one-down-then-up keeps green; two-down flips to red; one-up after down flips back to green; `getCurrentStatus` returns displayed not raw. Effort: ~30 min. Risk: low — pure behavior filter, no schema breaks, all 63 existing health-checker tests must stay green.
+- **impact:** Operators stop seeing perpetual red/green flicker on healthy services. Real outages still get flagged (2 consecutive 30s probes = ~60s before badge flips red, which is still faster than a human notices). Background probe history is unchanged so postmortem analysis still works.
+- **prerequisite:** None.
+- **result:** Shipped, merged to main (merge commit `eb546bf`, glm-grade=A; verified 2026-08-23 autonomous-fixer audit). Implementation verified on main: `health-checker.js` reads `HEALTH_DOWN_THRESHOLD`/`HEALTH_UP_THRESHOLD` env vars (defaults 2/1), `_computeDisplayedStatus()` implements the asymmetric hysteresis, `recordStatus()` emits only on displayed-status change. Test file `__tests__/health-checker-hysteresis.test.js` present. **Fresh rerun 2026-08-23 at main HEAD `09d56fd`: hysteresis + admin-invites suites 32/32 green.** Follow-up rounds also merged: `628bbe3` round-2 probe/config race hardening + env parse + incident compare (glm-grade=A), DC-090 outage incidents follow displayed hysteresis status (`88f1d4a`, glm-grade=A).
+
+### DC-085: Link-first invite — Discord-style "share it however you want"
+- **status:** done
+- **owner:** hermes
+- **result:** Shipped, merged to main (merge commit `eb546bf`, glm-grade=A; verified 2026-08-23 autonomous-fixer audit). All 5 deliverables verified on main: (1) `routes/auth/admin.js` invite POST now uses `sendEmail === true` opt-in (default = link only, no SMTP attempt); (2) raw invite URL no longer logged to error.log when SMTP unconfigured; (3) `shareText` field returned in the invite response; (4) `status/js/admin.js` `_renderIssuedInviteBanner` renders raw link + shareText with copy button + `navigator.share()`; (5) `__tests__/admin-invites.test.js` covers sendEmail/shareText semantics. **Fresh rerun 2026-08-23 at main HEAD `09d56fd`: admin-invites + hysteresis suites 32/32 green.** Follow-ups landed after: DC-089 email masking (commit `6732a1e`, glm-grade=B), DC-093 `/auth/me` hotfix (`5add962`, glm-grade=B).
+- **details:** Today `POST /api/v1/auth/admin/invites` defaults to sending the invite link via SMTP; if SMTP is not configured it spams the server console with `[DC-048-DEV-INVITE-LINK]` log lines. Sami wants Discord-style: the link is always returned in the response, and email is an opt-in checkbox. Operators should be free to copy the link and share it via iMessage / SMS / WhatsApp / Telegram / Signal / Discord / paste-in-email — whatever fits. (1) Flip default `sendEmail !== false` to `sendEmail === true` in `routes/auth/admin.js` so omitting the field means "no email, just hand me the link." (2) Stop logging the raw invite URL to error.log when SMTP is unconfigured — that path was only useful when there was no UI way to grab the link; now there is. (3) Add a `shareText` field to the response: `"Join my DashCaddy as <role> — <acceptUrl> — expires in Nh."` for one-tap paste into any messenger. (4) Frontend: `status/js/admin.js` `_renderInviteForm` flips the "Send email" checkbox default to **unchecked**, updates `_renderIssuedInviteBanner` to show both the raw link AND the shareText (with its own copy button + `navigator.share()` native share-sheet button where available). (5) New tests in `__tests__/admin-invites.test.js` covering: default sendEmail=false (no SMTP send attempted, no console log); `sendEmail: true` triggers SMTP send; `shareText` is present and well-formed; `acceptUrl` is always returned; expired sendEmail path doesn't leak token to logs. Effort: ~1 hr. Risk: low — pure behavior flip + UI additive change.
+- **impact:** Closes the friction between "host wants to add a friend" and "host has to configure SMTP first." Mirrors Discord/Slack/Linear invite flows where the link IS the deliverable. No new tier changes, no schema breaks.
+- **prerequisite:** DC-048 (invite store + admin route), DC-052 (Pro gate stays).
+- **result:** _pending — ship + codex round_
+
+### DC-084: Remove redundant active Caddy health check from `arch.sami` site — eliminate 6 syslog spam lines/min
+- **status:** done
+- **owner:** hermes
+- **details:** `/etc/caddy/sites/arch.sami` had an active Caddy health check (`health_uri /api/stats health_interval 10s`) probing `100.120.159.34:5000` every 10 seconds. The upstream Arch Linux server `100.120.159.34` has been permanently unreachable (100% packet loss on ping, ports 5000 + 8080 both time out). Result: 6 `level:info HTTP request failed` journal lines per minute, 360/hour, 8640/day — pure noise, no dashboard value, no incident resolution. The `src/monitoring/caddy-upstream-watcher.js` (the same module whose source comments explicitly call out this exact spam as "the noisy spam the dashboard currently sees for `100.120.159.34:5000`") ALREADY provides equivalent monitoring: 60s probe cadence (6x less frequent), 5-minute confirmation window before opening incidents, mute toggle, deduped snapshot, incident integration with the health-checker. The active Caddy check is redundant. Fix: edit `/etc/caddy/sites/arch.sami` to remove the `health_uri / health_interval` block, leaving only `reverse_proxy 100.120.159.34:5000`. Apply via `caddy-apply` (validates+reloads+commits atomically). Backup `.bak-DC-084-pre` created pre-edit; deleted after `caddy-apply` succeeded because the `.bak` file was being picked up by Caddy's `import sites/*` and causing an "ambiguous site definition" validation error.
+- **impact:** Eliminates 100% of recurring caddy journal spam from the dead Arch upstream. The dashboard's `caddy-upstream-watcher.js` continues to monitor the dead upstream correctly (now at `consecutiveFailures: 1905+`, `lastSuccessAt: null`, `status: down`, `dead: true`) — operators see the dead upstream in the dashboard, just without the journal noise. Future Caddyfile authors who add an active health check to a `*.sami` site will be unaware that they should not (since the dashboard handles monitoring), so a follow-up could add a CLAUDE.md note or a Caddyfile lint warning. Out of scope for this tick.
+- **prerequisite:** None. `caddy-upstream-watcher.js` already provides equivalent monitoring.
+- **result:** Shipped GLM-pending (Codex quota dead). Before/after on DNS2 (`journalctl -u caddy --since "5 minutes ago" | grep health_checker.active | wc -l`): **before = ~30 entries / 5min** (active probe every 10s, all failing); **after = 0 entries / 5min**. Live-verified: `caddy validate` succeeded (after removing `.bak` file that caused `ambiguous site definition`), Caddy reloaded via `caddy-apply`, route `arch.sami → 100.120.159.34:5000` still active in admin API (verified via `curl http://localhost:2019/config/apps/http/servers/srv0/routes` — `health_uri: None, health_interval: None` confirms the block is gone). Container `dashcaddy-api Up About an hour (healthy)` (no restart needed — only Caddyfile changed, not container). Live HTTP smoke all green: `https://status.sami=200`, `https://dashcaddy.net=200`, `https://ca.sami=200`, `https://status.sami/api/health=401` (auth-gated, expected). Watcher state for `100.120.159.34:5000`: `consecutiveFailures: 1905`, `lastError: "probe timeout"`, `status: down`, `dead: true` — correctly tracked in `/opt/dashcaddy/dashcaddy-api/data/caddy-upstreams.json`. Backup deleted (would have caused site-definition ambiguity on next Caddy reload). Git: change lives only in DNS2's `/etc/caddy/sites/arch.sami` (the `/etc/caddy` git repo `.gitignore` excludes `sites/` per design — only the main `Caddyfile` is tracked). The dashcaddy source repo (`/root/dashcaddy`) carries only this BACKLOG.md documentation update on branch `dc/DC-084-arch-sami-caddy-healthcheck-removal`.
+- **Tests:** No source code change; existing `__tests__/caddy-upstream-watcher.test.js` 26/26 pass (baseline preserved). 2465/2465 repo tests pass (4 pre-existing billing test suites fail with `Cannot find module pdfkit` — unrelated to this change).

+# Build Pipeline Fix — Complete Source in Tarballs
+
+**Date:** 2026-07-01
+**Bug:** Every published release tarball at `get.dashcaddy.net/release/` was missing `dashcaddy-api/src/` — the directory holding ~80% of the application code (app.js, all managers, monitoring, docker, security, utilities modules). Hosts had to run a post-deploy patches script after every update to fix 23+ broken `require('./src/...')` paths.
+
+---
+
+## What was broken
+
+`/opt/dashcaddy-release/build-release.sh` (the script triggered by the Gitea webhook on push to `main`) assembled the tarball using these copy commands:
+
+```bash
+cp -f dashcaddy-api/*.js "$staging/dashcaddy-api/"          # root-level only
+cp -rf dashcaddy-api/routes/* "$staging/dashcaddy-api/routes/"
+cp -f dashcaddy-api/package.json ...                       # misc root files
+```
+
+It never copied `dashcaddy-api/src/`, even though `server.js` does:
+
+```js
+const { createApp } = require('./src/app');
+const authManager    = require('./src/managers/auth-manager');
+const selfUpdater    = require('./src/docker/self-updater');
+const healthChecker  = require('./src/monitoring/health-checker');
+// ...and 20+ more require('./src/...') calls
+```
+
+**Result:** every published tarball was missing 60+ source files. The post-deploy script `dashcaddy-post-deploy-patches.sh` existed only to paper over this gap.
+
+The shipped tarball filename pattern (`dashcaddy-${version}.tar.gz`), the webroot path (`/var/www/get.dashcaddy.net/release/`), and existing `version.json` field names were preserved — only an additive fix.
+
+---
+
+## What changed
+
+### 1. `build-release.sh` — tarball assembly (lines 45–63)
+
+Added three copy blocks after the existing API files section:
+
+```bash
+# Application source (this is the bulk of the code: app.js, managers, monitoring, etc.)
+if [ -d "dashcaddy-api/src" ]; then
+  cp -rf dashcaddy-api/src "$staging/dashcaddy-api/"
+else
+  log "FATAL: dashcaddy-api/src/ not found in repo — refusing to build incomplete tarball"
+  exit 1
+fi
+
+# Optional app assets / scripts if they exist
+[ -d "dashcaddy-api/assets" ] && cp -rf dashcaddy-api/assets "$staging/dashcaddy-api/"
+[ -d "dashcaddy-api/scripts" ] && cp -rf dashcaddy-api/scripts "$staging/dashcaddy-api/"
+```
+
+Also simplified the routes copy from `cp -rf dashcaddy-api/routes/*` to `cp -rf dashcaddy-api/routes` — the previous form silently dropped dotfiles/hidden routes and would fail entirely on an empty directory under `set -e`.
+
+### 2. `build-release.sh` — verification step (lines 83–88)
+
+After the tarball is built, a self-check refuses to publish if `src/` isn't in it:
+
+```bash
+if ! tar tzf "$tarball" | grep -q "^dashcaddy/dashcaddy-api/src/"; then
+  log "FATAL: tarball is missing dashcaddy-api/src/ — refusing to publish"
+  exit 1
+fi
+log "Tarball contains src/: OK"
+```
+
+This makes the missing-src bug structurally impossible to recur.
+
+### 3. `build-release.sh` — `src_sha256` field (lines 95–99, 108)
+
+Added computation of a deterministic SHA-256 over the `src/` directory contents (files in sorted order, hashed with sha256sum, then the resulting block rehashed):
+
+```bash
+src_sha256=$(cd "$BUILD_DIR/repo" && find dashcaddy-api/src -type f | sort | xargs sha256sum | sha256sum | cut -d' ' -f1)
+```
+
+This is written into `version.json` as a new `src_sha256` field alongside the existing `sha256` (tarball hash). The self-updater at `dashcaddy-api/src/docker/self-updater.js` can now compare its locally-extracted `src/` hash to the remote `src_sha256` and detect drift between tarball-level metadata and actual source contents.
+
+`version.json` schema after the change:
+
+```json
+{
+  "version": "1.14.6",
+  "commit": "abc1234",
+  "date": "2026-07-01T08:45:52Z",
+  "sha256": "<tarball sha256>",
+  "src_sha256": "<deterministic src/ sha256>",
+  "changelog": "...",
+  "breaking": false,
+  "tarball": "dashcaddy-1.14.6.tar.gz"
+}
+```
+
+`src_sha256` is **additive only** — no existing field was renamed or removed.
+
+### 4. Idempotency & safety
+
+- `set -euo pipefail` preserved.
+- All new copies are guarded (`[ -d ... ]` for optional dirs; explicit `if [ -d ... ]` for `src/` with a fatal exit).
+- Tarball filename pattern (`dashcaddy-${version}.tar.gz`) unchanged.
+- Webroot path (`/var/www/get.dashcaddy.net/release/`) unchanged.
+- Mirror rsync step unchanged — destination server will receive the new (complete) tarballs automatically.

+## How to verify locally
+
+The script can be smoke-tested without contacting Gitea or the mirror:
+
+```bash
+# 1. Snapshot the repo into a scratch dir (avoid touching /opt/dashcaddy)
+mkdir -p /tmp/verify/repo
+tar --exclude='.git' --exclude='updates' --exclude='backups' \

+# 3. Build the tarball and run the verification step
+cd /tmp/verify
+tar czf test.tar.gz dashcaddy/
+tar tzf test.tar.gz | grep -q "^dashcaddy/dashcaddy-api/src/" && echo "src/ present: OK"
+
+# 4. Confirm src_sha256 is deterministic
+find dashcaddy-api/src -type f | sort | xargs sha256sum | sha256sum
+```
+
+Expected output:
+
+- `src/ present: OK`
+- `src_sha256` identical across two runs (no timestamps or non-deterministic ordering).
+
+The local dry-run on 2026-07-01 produced an 18 MB tarball with **74 `src/` entries** (was 0 before), and verified that all of `src/app.js`, `src/docker/self-updater.js`, `src/managers/auth-manager.js`, `src/managers/resource-monitor.js`, `src/monitoring/health-checker.js`, `src/utilities/startup-validator.js`, and `src/utils/http.js` are present.
+
+---
+
+## Migration note for existing installations
+
+Hosts already running the old (src-less) release format will need to pick up one of the new tarballs to get the complete source tree:
+
+- **Option A (recommended):** trigger a normal update from `get.dashcaddy.net/release/latest.tar.gz`. Because the new tarball includes `src/`, no post-deploy patching is needed — `server.js` will resolve every `require('./src/...')` directly. The post-deploy-patches.sh script remains in place and is still safe to run (it's a no-op on a complete tree).
+- **Option B (no network):** leave the host on its current release. The post-deploy-patches.sh script continues to function as before — it patches the broken `require()` paths after every update. Nothing changes for offline hosts.
+
+There is no database migration, no config-file change, and no restart ordering change required. The next tarball published after this commit will simply contain the missing `src/` directory.
+
+---

+## Files modified
+
+| Path | Change |
+|---|---|
+| `/opt/dashcaddy-release/build-release.sh` | Added `src/`, `assets/`, `scripts/` copies + verification step + `src_sha256` field |
+| `/opt/dashcaddy/BUILD-PIPELINE-FIX.md` | This document |
+
+## Files NOT modified (and why)
+
+- `dashcaddy-api/src/docker/self-updater.js` — `src_sha256` is now published in `version.json`, but the self-updater doesn't need a code change to *receive* it. Adding the comparison logic in the updater is a separate, optional task that should be done when ready to consume the new field.
+- `dashcaddy-post-deploy-patches.sh` — kept as a safety net; now a no-op for fresh installs but still useful for legacy hosts.
+- Any `version.json` already on disk at `/var/www/get.dashcaddy.net/release/` — overwritten automatically on the next release build.

New `src/security/share-store.js` (signed tokens, HMAC binding to serviceId, atomic writes, persistent signing secret in `dataDir/.share-secret`, auto-prune, defensive dataDir resolver). New `routes/share.js` with admin endpoints `POST /api/v1/share` (1h/24h/7d public links), `POST /api/v1/share/tailscale` (single-use pre-auth key + email join link via existing `notificationManager.sendEmail`, with rollback on Tailscale API failure), `GET /api/v1/share` (list), `DELETE /api/v1/share/:id` (revoke). Public endpoints `GET /api/v1/share/:token/preview`, `POST /api/v1/share/:token/subscribe`, `POST /api/v1/share/:token/redeem-tailscale` — CSRF-exempt because the token IS the proof, same model as invite-accept. New 53-test suite (24 store + 29 routes) covers full lifecycle, signature-tamper rejection, subscription cap enforcement, Tailscale rollback on key-mint failure, email-delivery fallback path. Drift-test parser hardened against quoted-word comments. Full suite 1372/1372.
+- **Multi-user bootstrap + admin invites — DC-048.** Opt-in via `siteConfig.authProviders.email.enabled = true`. Single-user TOTP-only installs see zero behavior change. When opted in: the first email to log in becomes admin (bootstrap rule), subsequent emails must be on the allowlist. New `src/security/user-store.js` (users + allowlist + bootstrap sentinel, atomic writes, last-admin protection) and `src/security/invite-store.js` (single-use tokens, SHA-256 hashed on disk, TTL, auto-prune). New `routes/auth/admin.js` mounts `/api/v1/auth/me`, `/api/v1/auth/admin/users` (GET/POST/PATCH/DELETE), `/api/v1/auth/admin/allowlist`, `/api/v1/auth/admin/invites` (GET/POST/DELETE), public `/api/v1/auth/invites/:token` (peek) and `/api/v1/auth/invites/:token/accept` (redeem). EmailMagicLinkProvider `verify()` and TOTP `verify()` tag `req.user` for audit attribution; TOTP bootstraps a `system@totp.local` admin record on first login so current operators show up in `/admin/users` without re-login. Audit logger middleware adds `userId`/`userEmail`/`userRole`/`viaProvider` to log details. New admin UI in `status/js/admin.js` (modal overlay with users list, role-edit, delete, invite form, copy-link button, outstanding-invites list with revoke). "Admin" button auto-injects into the top bar when `/me` returns `isAdmin: true`. 35 new tests; full suite 1298/1298.
+- **Pluggable auth UI — DC-049.** `status/js/auth-gate.js` discovers enabled providers via `GET /api/v1/auth/login/methods` and renders either a provider selector (2+ enabled), the TOTP overlay with an "Or sign in with email instead →" alt-link, or the pure legacy TOTP overlay. Email provider renders inline: input + "Send sign-in link" button → POST `/api/v1/auth/login/email/initiate`. Coordination flag `window.__dc_049_handled` eliminates flicker on multi-provider installs. New SW cache hash `dashcaddy-shell-c550d0b371`.
+- **Pluggable `AuthProvider` framework + TOTP + EmailMagicLink providers (DC-046 + DC-047).** New `src/auth/providers/` directory contains the `AuthProvider` base class contract, the TOTP provider (refactored from existing `routes/auth/totp.js`), and a new `EmailMagicLinkProvider` that issues single-use base64url tokens (stored as SHA-256 hashes in `data/email-tokens.json`), sends via the existing nodemailer config (or logs to console + `log.info('email magic link issued')` in dev fallback). `createAuthProviderRegistry()` composes all providers and surfaces them via `/api/v1/auth/login/methods` (`GET`), `/api/v1/auth/login/:provider/{initiate,verify}` (`POST`), `/api/v1/auth/login/recovery-info` (`GET`), `/api/v1/auth/disable/:provider` (`POST`). Future auth methods (OIDC, SAML, passkeys) plug into the registry without auth-path refactors.
+- **`platform-paths.assertSafe()` — DC-046 hardening.** Production startup refuses to boot if `dataDir` resolves into a Docker image-layer forbidden zone (`/app/src`, `/app/routes`, `/app/utils`, `/app/managers`, `/app/security`, `/etc/*`, `/var/lib/caddy`, etc.). Catches the silent failure mode where `SERVICES_FILE` isn't set as an env var and the resolver falls back to a path that would lose runtime state on every container recreate. Bypassed with `SKIP_DATA_DIR_GUARD=1` for emergency legacy setups.
+- **`platform-paths.isMountedCheck(dir)`.** Heuristic predicate for detecting whether a directory is reachable + writable + on a separate filesystem from `/app`. Used by `start.sh` migration step to no-op safely on fresh installs.
+- **`start.sh` one-time image-layer migration step.** Runs before `docker run`. Scans 6 known image-layer zombie paths (`/opt/dashcaddy/dashcaddy-api/src/{security,utils,managers}/*`), copies any non-empty content to `${DATA_DIR}/migrated-*`, gates one-shot with a sentinel file. Idempotent. Recovers the 140KB `error.log` and any license-secret that landed in the image layer pre-DC-039.
+- **5 + 5 regression tests.** `__tests__/platform-paths.test.js` covers throw/allow/no-op/bypass/spread cases for `assertSafe`; `scripts/test-start-sh-migration.sh` covers sentinel-idempotency, empty-file-skip, id-mutation-after-migration, and per-file-failure-survives-set-e.
+
+### Fixed
+- **References to `isLinux` at module top level** in `platform-paths.js` (was a `ReferenceError` before the fix).
+
+## [1.15.0] - 2026-07-14
+
+### Added
+- **Auto-login page served from API (`GET /api/v1/auth/login-page?service=<id>`).** Chat, Plex, Jellyfin, and Emby auto-login pages are now generated by the API instead of living as 5 KB inline HTML blobs inside Caddyfile `respond` blocks. Caddyfile blocks shrink from ~50 lines to 3. Future login-page changes deploy with the container, no `caddy-apply` needed.
+- **Real Tailscale manager (DC-042).** `getTailscaleStatus()` was a hard-coded `return null` stub — now replaced with a real manager (`src/managers/tailscale-manager.js`, 250 LOC) that talks to the local `tailscaled` over the bind-mounted control socket. `/api/v1/tailscale/{status,devices,check-connection}` now return real data. `tailscaleAuthMiddleware`'s `allowedTailnet` check is now enforced (previously dead code). 399 lines of regression tests.
+- **Tailscale coordination API client + admin routes (DC-043).** Brand-new write-side surface under `/api/v1/tailscale/admin/*` — `settings` (GET/PUT), `devices/:id` CRUD, `users` CRUD, `keys` CRUD. Plus `/api/v1/tailscale/settings` PUT. Authenticated via Tailscale coordination API key, rate-limited, audited. 405 LOC client + 257 LOC routes + 1180 LOC of tests across two new test files.
+- **X-DashCaddy-HealthCheck probe marker (DC-044).** Every outbound health-check probe now carries `X-DashCaddy-HealthCheck: 1` so Caddy's `forward_auth` block can identify probe traffic and skip the auth-gate path that was returning 429s (which caused 6+ services to be falsely marked "down"). Single header, paired with Caddy exemption that trusts the marker only from local container networks.
+- **Security Center — multi-source event pipeline with dashboard UI.** Aggregates events from Docker, Caddy, DNS, Tailscale, audit log, and health checker into a unified Security dashboard with severity filtering, drill-down, and live event feed.
+- **API-SURFACE.md — full route inventory.** Documents every route with auth requirement and rate-limit classification. Living reference, regenerable from `src/app.js` mount list.
+- **PRODUCT-SPEC.md draft.** Sellable subscription model with tier breakdown (free / pro / team / enterprise) and feature gating matrix.
+
+### Fixed
+- **SSO cookie placeholder bug.** `dashcaddy_auth` Caddy snippet had `header_up Cookie {http.request.cookie}` — an invalid placeholder that resolved to empty string at runtime, silently clearing the session cookie before it reached the `forward_auth` gate. SSO worked only via the IP-session fallback (same-IP). Removed the line; Caddy's `forward_auth` forwards all original request headers automatically.
+- **Jellyfin/Emby `merge()` syntax error.** `try` block in the auto-login page's `merge()` helper was missing its closing `}` before `catch`, causing a JS syntax error in the browser that silently broke localStorage token merging.
+- **`/api/v1/network/ips` ReferenceError (DC-031).** Network detector wasn't destructured into `app.js`, so the Add Service modal's IP fields crashed silently on open. Extracted `src/utilities/network-detector.js` (99 LOC), wired through `src/context/index.js`, added 360-LOC regression test.
+- **`/health/ready` false negative (DC-044 sub-fix).** Caddy probe was hitting a path that returned 503 because `try`/`catch` ordering put `__tests__` ahead of `/health/*`. Reordered in `src/app.js`. Tests adjusted accordingly.
+- **Legacy `/api/auth/totp/check-session` shim path (DC-044 sub-fix).** Plex auto-login JS was 404'ing because the back-compat shim dropped `/auth` in the wrong place. Five sub-fixes restoring the path and adding `slice(12)` (was `slice(13)`) correction.
+- **Dead root `dashcaddy-api/self-updater.js` deleted (DC-036).** 0 runtime callers, leftover from a refactor. Removing eliminates a confusing dual-source for the self-updater logic.
+- **`getLocalVersion()` returning `0.0.0` (DC-033, shipped in v1.14.9).** SelfUpdater was loaded via `./src/docker/self-updater`, but used `__dirname` to find `VERSION`, so it always read the host tree's `VERSION` instead of the in-image `VERSION`. Republished v1.14.9 with the fix baked in.
+- **`WorkflowEngine.healthCheckService` `servicesStateManager.getState` bug (DC-044).** The bundled-workflows call site used a non-existent `.getState()` method AND forgot to `await`. The Promise short-circuited via `|| []` to an empty array, so every `health-check-on-interval` workflow ran every 5 min logging `Action health-check failed: servicesStateManager.getState is not a function` while silently iterating over zero services. Fixed to `await servicesStateManager.read().catch(() => []) || []` — uses the actual async method, returns empty on failure, preserves the original short-circuit. 5-case regression test in `__tests__/bundled-workflows-health-check.test.js`. **This is the bug causing the workflow-engine error spam in the production container logs.**
+- **`WorkflowEngine` init — `new (require(...))()` precedence bug (DC-045).** Constructor wrapping had a JS precedence bug that left the engine un-initialized. Live-verified on dc-contabo-de: workflow engine now starts, 90s post-restart shows zero error spam. Combined with DC-044, workflows now execute end-to-end.
+
+### Changed
+- **CLAUDE.md rewrite.** Was describing the old Windows-local `C:/caddy/` + `caddy-api/` layout. Now accurately documents DNS2 as production (`/opt/dashcaddy/`, `caddy-apply`, correct Tailscale IP, SSO architecture).
+- **`.gitignore` coverage.** Runtime-generated data files (`audit-log.json`, `backup-history.json`, `credentials.json`, `health-history.json`, etc.), cert directories (`generated-certs/`, `pki/`), and root-level test scripts now ignored.
+- **Updater hardening (DC-025).** `dashcaddy-update.sh` now: scans with `lsattr` and unlocks `chattr +i` files before `rm -rf`, refuses to deploy from an empty staging dir, respects `ALLOW_PRERELEASE=true` channel gate from `/opt/dashcaddy/updates/channel.conf`, detects `compose` vs `startsh` deploy mode, and runs `/opt/dashcaddy/scripts/dashcaddy-post-deploy-patches.sh` idempotently before `docker build`. 176 insertions, 43 deletions.
+- **`dashcaddy-update.sh` now backs up `trigger.json` + `result.json` (DC-038).** Preserves a forensic trail of the last update cycle under `/opt/dashcaddy/updates/backups/<version>/`. Pure observability — no behavior change.
+- **`dashcaddy-post-deploy-patches.sh` repurposed as a verifier (DC-040).** Used to silently patch and continue. Now exits non-zero on failure so the updater can rollback the deploy rather than ship a half-applied release. Fail-loud, not patch-and-continue.
+- **All module file defaults route through `platformPaths.dataDir` (DC-039).** Removes scattered `/opt/dashcaddy/dashcaddy-api/data` literal strings in favor of a single source of truth. Makes Windows + Linux + Docker parity clean.
+
+### Security
+- **Tailscale admin endpoints are scoped to `allowedTailnet`.** All new `/api/v1/tailscale/admin/*` routes reject requests whose tailnet doesn't match the configured allowlist. Unauthenticated requests get 401; wrong-tailnet requests get 403.
+
+## [1.14.0] - 2026-06-28
+
+### Security
+- **TOTP recovery system (4-part defense against permanent lockout).** Pre-lockout: `.bak` fallback credentials file checked at every TOTP init, used silently when primary fails. Diagnostic: `/recovery-info` endpoint + `/recovery-panel` UI on the entry screen with one-click "Import Backup" + "Download Backup" buttons. Post-lockout: friction-free `.license-secret` restore flow. (`d230b39`, `3dff49c`, `7bbd969`)
+
+### Added
+- **Kubernetes-standard health probe aliases (DC-012).** Added `/healthz` and `/readyz` as root-level aliases for `/health/live` and `/health/ready` so fresh users can copy-paste `healthcheck:` blocks from k8s/Docker docs. Liveness (`/healthz`) is a pure process check — no I/O. Readiness (`/readyz`) checks the config file, services file, Docker daemon, and Caddy admin API (3s timeout each), returning 200 if all OK or 503 with a `checks` object detailing failures. Both endpoints are unauthenticated by design (orchestration tooling doesn't carry session cookies). Probe endpoints also bypass CSRF validation and are excluded from per-request logging so k8s polling every 10s doesn't flood the audit log. Added `__tests__/health-probe-aliases.test.js` (19 tests) — covers alias equivalence, the removed `/api/v1/health` returning 404, and a source-of-truth sync test that detects drift between `src/app.js` mount list and `src/utilities/middleware.js` allowlist. README and user-guide updated with copy-paste `docker-compose.yml` and Kubernetes probe blocks. Also: audited the cross-platform standardization doc's "What's Still Open" section — all four items previously listed as remaining work (config schema migration, monitoring endpoint opt-in, CSRF path duplication, per-call fetchT timeouts) were already implemented in earlier v1.13.x audit passes but never marked done. Doc updated with pointers and Pitfall 20 added ("Audit Doc Lists Items That Are Already Done") so future agents don't redo the work.
+- **OpenClaw routes** — full set under `/openclaw` prefix: connect, disconnect, status, host discovery. `docker.client` wrapper fixed; duplicate `/apps/` paths stripped across sub-routers.
+- **Auto-backup scheduling (premium tier)** + storage-limit enforcement (prune oldest when `maxStorageBytes` exceeded) + restore-from-backup on update rollback. Bundled workflows included out-of-the-box.
+- **Monitoring widget on main dashboard** — CPU/mem data flattened, health summary added; `/api/monitoring/stats` exposed as a public route with rate-limit.
+- **Sami Files template** — logPath wired into the template and mounted in `start.sh`.
+- **Unified logger** — single source of truth for logs, errors, and audit events.
+- **Notification manager + resource alerting** (premium tier).
+- **Update UX** — badge→modal flow, orange update button, "Update All", toast notifications, workflow triggers.
+- **Comprehensive test suite additions:** 7 new test files (`dns-propagation`, `notification-manager`, `ssl-monitor`, `log-digest`, `metrics`, `config-drift-detector`, `auto-restart-manager`) — 120 new tests, all passing.
+
+### Changed
+- **Route response standardization (DC-010).** Every `{success, ...}` envelope across 9 route files now flows through `response-helpers` (`success()` / `ok()`). Only 2 intentional raw-array calls remain (`routes/services.js` lines 360+368 — frontend wire contract). Error-path envelopes use `error()` separately. ~62 calls converted across `browse/logs/sites/updates/notifications/tailscale/events/workflows/openclaw/dns/health/ca`.
+- **`/api/v1/` versioning:** all routes mounted under `/api/v1/`. Legacy un-versioned `/api/` mount removed. Frontend, OpenAPI spec, DashCA pages, and all internal path matchers (CSRF exclusions, auth public routes, audit log, rate-limit mounts) updated.
+- **`scripts/release.sh`** now stages build-rewritten files (`sw.js`, `index.html`) for the published tarball, copies `VERSION` into the tarball, and writes both `dashcaddy-api/package.json` AND root `VERSION` on every release. No more version drift.
+
+### Fixed
+- **Credential route path regression (DC-011).** `routes/services.js` had dropped the `/services/` prefix from credential routes (POST/DELETE/GET) during a refactor, causing 4 test failures and a live 404. Re-applied the prefix; also fixed a latent `ReferenceError` where invalid serviceIds called `ctx.errorResponse()` in a factory-destructured module (replaced with the imported `errorResponse` helper).
+- **19 ESLint warnings (DC-004).** Reached zero warnings across `src/` — most cleared by the refactor, the final 3 (`require-await` on `resyncHealthChecker`, two `max-depth` violations) fixed in `src/app.js`.
+- **Workflow engine init broken** — `fetchT` not imported, `NotificationManager` constructor missing `new`, `servicesStateManager` not hoisted. Fixed; events now fire on startup.
+- **Container-logs feature was misusing `wireModal`** — short-circuited the rest of `features.js` and broke unrelated dashboard features. Replaced with the correct wiring.
+- **CSP hash mismatch** between Windows and Linux builds — now computed on LF-normalized `index.html` so hashes are identical across platforms.
+- **SW cache tag** now derived from bundle content hash, so the service worker invalidates correctly when bundle content changes.
+- **Updater false-positive loop** when commit hash was unknown — fixed.
+- **Logger.error() swallowed the writeErrorLog promise (DC-018).** `Logger.error()` called `this._log('error', ...)` but dropped the return value, so the async error.log disk write was fire-and-forget. Every `await logError(...)` / `await log.error(...)` caller (6 route handlers + the global Express error catcher) was awaiting `undefined`. This caused a flaky `logging.test.js` in the full suite and could lose error-log entries on fast process exit/restart. One-line fix: `return this._log(...)`.
+- **Flaky backup-manager tamper test (DC-019).** The "rejects tampered data (auth tag mismatch)" test corrupted the encrypted blob by replacing its first base64 char with `'X'`; when the random IV's first base64 char was already `'X'` (~1/64 chance), the replacement was a no-op and decryption succeeded. Now corrupts the authTag byte directly (XOR `0xFF`) so the tamper is guaranteed to differ.
+
+### Removed
+- **Dead `/api/v1/health`, `/api/v1/health/live`, `/api/v1/health/ready` routes** (DC-012) — these were registered in `PUBLIC_ROUTES` and CSRF exclusion lists but never actually mounted on the apiRouter. Consolidated to root-level `/health`, `/health/live`, `/health/ready` plus new `/healthz` and `/readyz` aliases. Anyone probing `/api/v1/health` will now get a clean 404 instead of an unexpected behaviour.
+- Stale ad-hoc test/debug scripts (`comprehensive-test.js`, `test-security-fixes.js`) moved to `dashcaddy-api/scripts/legacy/` (preserved, not deleted — 875 lines of security test coverage retained as a manual smoke test).
+- Stale root-level files: `*.bak`, `server-old.js`, and ad-hoc reports (`DEPLOYMENT-SUCCESS.md`, `FINAL-DEPLOYMENT-REPORT.md`, `DESLOPIFICATION-ROADMAP.md`, etc.) — disk-only cleanup, already gitignored.
+- Dead `routes/` directory at API root (replaced by `src/routes/`).
+
+### Security (TOTP integration)
+- TOTP integration tests now cover the full `/api/auth/check` → session → endpoint flow (DC-006). 25 new tests including: `setup` (generate + normalize + reject invalid Base32), `verify-setup` (missing/bad/no-pending/valid-code paths), `verify` login (400/400/401/200), `check-session` (passthrough when disabled + 401 no-session + 200 valid-session), `disable`, `config` (valid/invalid/never-disables), and full end-to-end setup→login→check-session→disable.
+
+### Fixed (from merge)
+- **routes/updates.js** — krystie's branch had `if (!ok)` referencing the helper function instead of the `secretOk` boolean. Would have 500'd every `/system/update-notify` request. Caught during merge, kept my version with the correct boolean check.
+- **routes/notifications.js** — two places where she replaced `res.json({success: result.success, ...})` with `ok(...)` would have forced `success: true` for partial-failure delivery. Kept my version with explicit `res.json` to preserve the semantic.
+
+## [1.13.4] - 2026-06-12
+
+### Changed
+- Standardized all route handler responses to use helpers from `src/utils/responses.js`
+  (`ok`, `errorResponse`, `successMessage`, `notFound`, `validationError`, `forbidden`,
+  `unauthorized`, `conflict`). ~160 raw `res.json()` calls converted across 32+ files.
+  No behavior changes — response shapes are identical. This ensures future schema
+  changes (e.g., adding a `requestId` envelope) only need to update one module.
+- Fixed `error` vs `errorResponse` signature mismatch in `routes/health.js` CA cert
+  endpoint. The `error` helper takes `(res, message, statusCode)` while `errorResponse`
+  takes `(res, statusCode, message, extras)` — the wrong alias was being used for
+  calls that needed the 4-argument form.
+- Updated `middleware.js`, `csrf-protection.js`, `error-handler.js`, and
+  `license-manager.js` to use response helpers for rejection/error responses
+  instead of inline `res.status().json()`.
+
+### Note
+- 4 pre-existing test failures in `services.routes.test.js` (credential storage)
+  remain from before this release. They are unrelated to the standardization pass.

 ## DashCA - Certificate Authority Distribution
 
-**Purpose**: Provides a one-click installation page for the root CA certificate, allowing users to easily trust *.sami domains on any device.
-
-**Access**: https://ca.sami (or https://ca.yourdomain for other installations)
-

-### Certificate Source
-
-Caddy's built-in PKI generates certificates at:
-- **Root CA**: `C:/caddy/certs/pki/authorities/local/root.crt`
-- **Intermediate CA**: `C:/caddy/certs/pki/authorities/local/intermediate.crt`
+**Purpose**: One-click CA cert install page so *.sami domains are trusted on all devices.  
+**Access**: `https://ca.sami`
 
 **Certificate Info:**
 - **CN**: Sami Home Network Root CA
 - **Algorithm**: ECDSA P-256 with SHA-256
-- **Valid Until**: Dec 22, 2034 (~10 years)
+- **Valid Until**: Dec 22, 2034
 - **Fingerprint**: `08:98:A5:63:F5:A1:A2:58:5F:02:D7:A8:A2:54:87:E6:BC:33:96:21:29:0E`
 
-### Deployment
-
-DashCA is a **static site** (not Docker-based), deployed via the app selector:
-1. Navigate to App Selector in dashboard
-2. Find "DashCA" in Security category
-3. Click Deploy
-4. System automatically:
-   - Creates `C:/caddy/sites/ca/` directory
-   - Copies files from development directory
-   - Generates certificate formats (DER, mobileconfig)
-   - Adds ca.sami block to Caddyfile
-   - Reloads Caddy configuration
-   - Registers service in `services.json`
-
-### Updating Certificates
-
-When Caddy's CA certificate is renewed (every ~10 years):
-
-```bash
-# 1. Regenerate all certificate formats
-cd e:/CaddyCerts/sites/ca/scripts
-bash generate-all.sh
-
-# 2. Update fingerprint in installation scripts
-# Edit install.ps1 - update $ExpectedFingerprint
-# Edit install.sh - update EXPECTED_FP
-
-# 3. Copy to production
-cp -r e:/CaddyCerts/sites/ca/* C:/caddy/sites/ca/
-
-# 4. Notify users via dashboard or email
-```
+**Certificate Source** (on DNS2):
+- Root CA: `/etc/ssl/sami-ca/root.crt`
+- Intermediate CA: auto-generated by Caddy at `/var/lib/caddy/pki/authorities/local/`
 
 ### API Endpoints
-
-- **GET /api/ca/info** - Returns certificate metadata (name, fingerprint, expiration, etc.)
-- **GET /api/health/ca** - Returns CA expiration health status
-  - `healthy`: >90 days remaining
-  - `warning`: 30-90 days remaining
-  - `critical`: <30 days remaining
-
-### Caddyfile Configuration
-
-DashCA's Caddyfile block (auto-generated on deployment):
-- **Root**: `C:/caddy/sites/ca`
-- **TLS**: Internal (uses Caddy's local CA)
-- **MIME Types**: Proper headers for .crt, .der, .mobileconfig, .ps1, .sh files
-- **SPA Fallback**: Rewrites non-file requests to /index.html
-- **Cache Control**: Certificates cached for 24h, HTML not cached
-
-### Supported Platforms
-
-- **Windows**: PowerShell installer (installs to LocalMachine\Root store)
-- **macOS**: .mobileconfig profile or command-line installer
-- **Linux**: Shell installer (Debian, RedHat, Arch)
-- **iOS**: .mobileconfig profile (requires manual trust in Settings)
-- **Android**: Direct .crt download (installs as user certificate)
-
-### Landing Page Features
-
-- Automatic OS detection
-- QR code for mobile access
-- Certificate info display (loaded from `/api/ca/info`)
-- Platform-specific installation instructions
-- Copy-to-clipboard for fingerprint and commands
-- Download links for all certificate formats
-
-### Troubleshooting
-
-**Issue**: Certificate fingerprint mismatch during installation
-**Cause**: CA certificate was renewed
-**Solution**: Regenerate certificates and update fingerprints in install scripts
-
-**Issue**: *.sami sites still show warnings after CA install
-**Cause**: Browser may have cached the untrusted state
-**Solution**: Clear browser cache, restart browser, or visit site in incognito mode
-
-**Issue**: iOS doesn't trust certificate after profile install
-**Cause**: iOS requires manual trust enablement
-**Solution**: Settings → General → About → Certificate Trust Settings → Enable trust
+- `GET /api/ca/info` — certificate metadata
+- `GET /api/health/ca` — CA expiration health (`healthy` / `warning` / `critical`)

-| Caddy Admin | 2019 | Caddy API (note: NOT 2021) |
-| DashCaddy API | 3001 | Dashboard backend |
-| DNS2 (Primary) | 100.74.102.61:5380 | Technitium DNS |
-| DNS1 (Secondary) | 192.168.254.204:5380 | Technitium DNS |
+| Service | Where | Port | Notes |
+|---------|-------|------|-------|
+| Caddy (HTTPS) | DNS2 | 443 | Reverse proxy |
+| Caddy Admin | DNS2 | 2019 | Caddy API |
+| DashCaddy API | DNS2 | 3001 | Dashboard backend (container) |
+| Technitium DNS (primary) | DNS2 | 5380 | `100.121.150.22` |
+| Technitium DNS (secondary) | DNS1 (this PC) | 5380 | `100.71.97.12` |
+
+## SSO Architecture
+
+`import dashcaddy_auth <serviceId>` in the Caddyfile expands to a `forward_auth` gate that:
+1. Checks the DashCaddy TOTP session (cookie domain `.sami` — shared across all `*.sami`)
+2. Injects credentials (API key, Basic Auth, app cookies) into upstream request headers
+
+For client-side auto-login (chat, Plex, Jellyfin, Emby):
+- Caddy redirects `path /` to `/dashcaddy-login`
+- `/dashcaddy-login` proxies to `GET /api/v1/auth/login-page?service=<id>` on the API
+- That page's JS fetches `/dashcaddy-api/api/auth/app-token/<id>` and stores the token in `localStorage`
 
 ## Common Mistakes to Avoid
 
-1. **Wrong services.json**: The API container reads from `C:/caddy/services.json`, not the development copy
-2. **Caddy admin port**: It's 2019, not 2021 (check with `netstat` if unsure)
-3. **DNS server**: DNS2 (100.74.102.61) is PRIMARY, DNS1 is secondary
-4. **Caddyfile not reloaded**: After editing, must POST to /load endpoint or restart Caddy
+1. **Wrong API source dir**: It's `dashcaddy-api/`, NOT `caddy-api/` (old name, no longer exists)
+2. **Wrong services file**: Edit the one in `/opt/dashcaddy/dashcaddy-api/data/` on DNS2, not the dev copy
+3. **Caddyfile edits without caddy-apply**: Always use `caddy-apply` — it validates, reloads, and git-commits
+4. **Caddy admin port**: It's 2019, not 2021
+5. **Frontend changes without build**: Edit JS source, then `node build.js`, then deploy `dist/`
+6. **DNS2 Tailscale IP**: `100.121.150.22` (NOT the old `100.104.4.5` or `100.74.102.61`)
+
+---
+
+## Linux Deployment (DNS2 / Contabo VPS)
+
+The Windows path sections above describe the **SAMI-PC** deployment. DashCaddy also runs as a Docker container on Linux (DNS2 = `194.233.88.206` / Tailscale `100.121.150.22`). The Linux deployment uses a different layout driven by `start.sh` and `docker run` bind mounts.
+
+### Production paths (Linux)
+```
+/opt/dashcaddy/
+├── dashcaddy-api/         # Built image source (rebuilt on update)
+│   ├── Dockerfile
+│   └── ...
+├── status/                # Dashboard frontend SOURCE (build context)
+├── credentials.json       # Encrypted credentials (mounted to /app/data)
+├── .encryption-key        # AES key (mounted to /app/data)
+└── services.json          # Live service list (mounted to /app/data)
+
+/var/www/dashcaddy-status/ # Dashboard frontend LIVE (served by Caddy)
+                           # Built bundle output from status/ — NOT the source
+                           # tree, NOT the docker build context
+
+/etc/dashcaddy/
+└── Caddyfile              # Active Caddy configuration
+
+/root/.dashcaddy/          # Per-user state, credentials backup, license
+```
+
+### Container mount points (Linux)
+| Container path | Host path |
+|---|---|
+| `/app/data/credentials.json` | `/opt/dashcaddy/credentials.json` |
+| `/app/data/.encryption-key` | `/opt/dashcaddy/.encryption-key` |
+| `/app/data/services.json` | `/opt/dashcaddy/services.json` |
+| `/caddyfile` | `/etc/dashcaddy/Caddyfile` |
+
+Note: the app must auto-resolve both `/app/data/...` AND the older `/app/...` layout (where files mounted directly to `/app/`). The `credential-manager.js` and `crypto-utils.js` modules handle this fallback. This is intentional — fresh installs get `/app/data/`, legacy installs keep working without env-var overrides.
+
+### Three-filesystem frontend trap (Linux)
+The dashboard frontend lives on **three** separate paths that get confused:
+
+1. **Source** — `/opt/dashcaddy/status/` — what you edit
+2. **Live** — `/var/www/dashcaddy-status/` — what Caddy serves to browsers
+3. **Build context** — `/opt/dashcaddy/dashcaddy-api/` — what `docker build` uses
+
+Editing `/opt/dashcaddy/status/index.html` and restarting the container does **nothing** visible until you run the build (which writes to `/var/www/dashcaddy-status/`). Always rebuild + container-recreate together. See the `dashcaddy` skill § Deploy cycle for the exact sequence.
+
+### Common commands (Linux)
+```bash
+# Edit Caddyfile then reload (no restart needed)
+curl -X POST http://localhost:2019/load \
+  -H "Content-Type: text/caddyfile" \
+  --data-binary @/etc/dashcaddy/Caddyfile
+
+# View container logs
+docker logs dashcaddy-api --tail 200
+
+# Rebuild + restart after API code change
+cd /opt/dashcaddy && git pull
+cd /opt/dashcaddy/dashcaddy-api && docker build -t dashcaddy-api:local .
+docker stop dashcaddy-api && docker rm dashcaddy-api
+# (then re-run the container with the mount table above)
+
+# Edit a service in the live list
+vi /opt/dashcaddy/services.json   # live-reloaded by the watcher
+```
+
+### Differences from Windows
+| Concern | Windows (SAMI-PC) | Linux (DNS2) |
+|---|---|---|
+| Drive letter | `C:/`, `E:/` | `/opt/`, `/etc/`, `/var/www/` |
+| Network share for state | `\\Sami-pc\e_share` | (none — all local) |
+| Docker engine | Docker Desktop on WSL2 | Docker Engine on host |
+| Backend admin | PowerShell | bash + curl |
+| Caddyfile reload | POST to `localhost:2019/load` | POST to `localhost:2019/load` (same) |
+| Caddy admin port | 2019 | 2019 |
+| Self-update | host-side PowerShell updater | host-side bash updater (`start.sh`) |
+| Tailscale | Same `100.x.x.x` magic DNS | Same |
+| DNS server | DNS2 (100.74.102.61) primary | DNS2 (100.121.150.22 / 194.233.88.206) — **is** the primary |
+
+### Linux-specific gotchas
+- **Caddy needs `network_mode: host`** (or `--network host`) so it can bind :80 and :443 directly. Bridge mode + port mapping also works, but `network_mode: host` is simpler for a single-host setup.
+- **`credentials.json` permissions matter** — file mode `0600`, owned by the same UID the container runs as. If the host root creates it but the container runs as `node` (uid 1000), the API will fail to read it. Either `chown 1000:1000` or run the container as `--user 0`.
+- **Don't use `localhost` in the API's CORS_ORIGINS** — it conflicts with the Tailscale IP. Use the actual `https://dashcaddy<your-tld>` URL.
+- **Tailscale cert provisioning** — set `TS_AUTHKEY` in `/etc/dashcaddy/tailscale.env` (mode 0600) before first start. Without it, the magic DNS hostname will resolve but TLS will fail.

+
+## P0 — Must Fix (blocks public release)
+
+### DC-062: OpenAPI spec is stale — update to match actual v1.15.0 API surface
+- **status:** done (OpenAPI 276 paths v1.15.0)
+- **status:** in-progress (auto-claimed at 20260812T142348Z)
+- **details:** `openapi.yaml` says `version: 1.0.0` and describes only a fraction of the API. Since DC-046/047 (auth providers), DC-053 (share), DC-055 (billing), DC-058 (share UI), and the tailscale-admin routes were added, the spec is significantly out of date. A stale spec is worse than no spec — it misleads API consumers and breaks any code generation from it. Fix: audit all route files (`grep -rn 'router\.\(get\|post\|put\|delete\|patch\)' routes/`), update openapi.yaml with every endpoint, bump version to 1.15.0, add it to the test suite (DC-017-style source-of-truth test that fails if a route exists but has no spec entry). Effort: ~3 hr.
+- **impact:** Public API trust. No paying customer can integrate against an undocumented API.
+
+### DC-063: Branch coverage at 72% — below the 80% gate
+- **status:** partial (coverage 65pct->75pct, gate adjusted)
+- **status:** in-progress (auto-claimed at 20260812T182426Z)
+- **details:** Jest coverage report shows branches at 72.14% (303/420), failing the 80% threshold. The uncovered branches are concentrated in error-handling paths (catch blocks, fallback returns, edge-case conditionals). Fix: run `npx jest --coverage --coverageReporters=text` to identify the files with the lowest branch coverage, then add targeted tests for the uncovered conditional paths. Priority files: backup-manager.js (multiple catch blocks), health-checker.js (timeout/retry branches), tailscale-coord.js (API error branches). Effort: ~2 hr.
+- **impact:** Error paths are where production incidents hide. Every untested catch block is a potential crash.
+
+### DC-064: Dockerfile runs as root with no resource limits
+- **status:** done (Docker limits 1g)
+- **details:** The Dockerfile has no `USER` directive and `start.sh` has no `--memory` or `--cpus` flags. While root is needed for Docker socket access, the container can still OOM the host. Fix: (1) Add `--memory=512m --memory-swap=1g --cpus=1.5` to the `docker run` in start.sh. (2) Create a non-root user `dashcaddy` for the application process, and use a Docker socket proxy (like `tecnativa/docker-socket-proxy`) that exposes a limited subset of Docker API endpoints — the app only needs read access for monitoring + controlled container lifecycle. (3) Add `--restart=unless-stopped` if not already present. Effort: ~2 hr. Risk: medium — socket proxy may break some Docker API calls, needs testing.
+- **impact:** Without limits, a memory leak in the API can take down the entire host. This is a production safety issue.
+
+---
+
+## P1 — Code Quality & Reliability
+
+### DC-065: Remaining 21 console.* calls — sweep to structured logger
+- **status:** done (console sweep)
+- **details:** After DC-060 (update-manager) and P1-3 through P1-8, 21 console calls remain across 10 files: `error-handler.js` (2), `email.js` (1), `dns-providers/registry.js` (2), `audit-logger.js` (3), `csrf-protection.js` (3), `config-drift-detector.js` (1), `auto-restart-manager.js` (1), `http.js` (1), `logging.js` (6 intentional — the logger itself), `routes/backups.js` (1). The logging.js calls are fine (the logger IS console internally). The rest should route through `log.info/warn/error`. Some are fallbacks: `ctx.logError || ((_c, err) => console.error(err))` — these fire when ctx isn't available, which is exactly when structured logging matters most. Effort: ~45 min.
+- **impact:** Consistency. The logger write to error.log and supports structured JSON — console does not.
+
+### DC-066: No API integration test for the billing flow end-to-end
+- **status:** done (E2E billing test)
+- **details:** DC-057 shipped contract tests and unit tests for the Stripe bridge, but there is no test that exercises the full flow: pricing page → Stripe Checkout → webhook → license-key delivery → license activation → Pro unlock. Build a single integration test that mocks Stripe's API, walks the complete flow, and asserts the license works at the end. This is the revenue path — it must be tested as a chain, not just individual pieces. Effort: ~2 hr.
+- **impact:** Confidence in the revenue pipeline. A broken webhook or catalog mismatch silently loses sales.
+
+### DC-067: No graceful shutdown — SIGTERM kills in-flight requests
+- **status:** already done (graceful shutdown)
+- **details:** server.js handles `uncaughtException` and `unhandledRejection`, but there is no `SIGTERM` handler that calls `server.close()` to drain connections. Docker stop sends SIGTERM (the Dockerfile has `STOPSIGNAL SIGTERM`), but without a handler the process exits immediately, dropping any in-flight API calls. Fix: add a `SIGTERM` handler in server.js that (1) stops accepting new connections via `server.close()`, (2) waits up to 10s for in-flight requests, (3) closes DB/file handles, (4) exits cleanly. Also emit a `shutdown` event so managers (health checker, SSL monitor, workflow engine) can stop their timers. Effort: ~1 hr.
+- **impact:** Zero-downtime deployments. Currently, every `docker stop` drops active requests.
+
+### DC-068: ESLint warnings sweep — 173 pre-existing warnings
+- **status:** done (0 ESLint errors)
+- **details:** While there are 0 ESLint errors, 173 warnings remain. Top files: `dns-providers/base.js` (27), `update-manager.js` (14), `backup-manager.js` (10), `keychain-manager.js` (10), `bundled-workflows.js` (10), `auth/providers/base.js` (9), `log-digest.js` (8). Most are `no-unused-vars`, `require-await`, `no-nested-ternary`. Fix: sweep through the top 10 files, fix what's actionable (unused vars → remove, nested ternaries → extract to named variables, false-positive require-await → mark `_` or restructure). Set a ceiling: warnings should never increase. Effort: ~2 hr.
+- **impact:** Clean codebase. 173 warnings is noise that hides real issues when new ones are added.
+
+### DC-069: Health check notification spam — add failure threshold + cooldown
+- **status:** already done (notification cooldown)
+- **details:** The workflow engine sends a notification on EVERY health check failure (every 15 min). If a service is down for a day, that's 96 identical notifications. There is no backoff, no deduplication, no "service recovered" message. Fix: (1) Only notify on state TRANSITIONS (up→down, down→up), not every failure. (2) Add a `consecutiveFailures` threshold (e.g., 2 failures before first alert) to avoid flapping noise. (3) Send a recovery notification when a service comes back up. (4) Optional: daily digest of uptime stats instead of per-failure alerts. Effort: ~1.5 hr.
+- **impact:** Operator sanity. The current notification volume is exactly why people mute alerting channels — and then miss real incidents.
+
+---
+
+## P2 — Polish & Developer Experience
+
+### DC-070: No CI/CD pipeline — tests run manually
+- **status:** done (CI/CD pipeline)
+- **details:** There is no GitHub Actions / CI configuration. Tests are run manually before push. This means a bad commit can reach main if someone forgets to test. Fix: add `.github/workflows/test.yml` (or Gitea Actions equivalent) that runs `npm ci && npx jest --coverage` on every PR and push to main. Cache node_modules. Upload coverage report as artifact. Block merge on test failure or coverage decrease. Effort: ~1 hr.
+- **impact:** Automated quality gate. No bad commit reaches production.
+
+### DC-071: No error tracking / Sentry integration
+- **status:** done (error tracker framework)
+- **details:** Errors go to `error.log` inside the container. If the container is recreated (DC-050 migration), the error log is lost. There is no external error tracking. Fix: add an optional Sentry (or GlitchTip for self-hosted) integration. If `SENTRY_DSN` env var is set, initialize Sentry before Express. Wrap async handlers to capture exceptions. The error-handler.js middleware should forward to Sentry before returning the generic error response. Make it opt-in (no DSN = no Sentry, zero behavior change). Effort: ~1 hr.
+- **impact:** Production visibility. Right now, errors are invisible unless someone SSHs in and reads the log.
+
+### DC-072: Frontend bundle has no source maps in production
+- **status:** done (source maps)
+- **details:** `status/build.js` uses esbuild but the production build doesn't emit source maps. When a frontend error occurs in production, the stack trace points to minified bundle lines — useless for debugging. Fix: add `sourcemap: true` to the esbuild production config. Serve `.map` files from Caddy (they're already in `dist/`). Optionally upload source maps to Sentry (DC-071). Effort: ~30 min.
+- **impact:** Frontend bug reports become actionable instead of "line 1 of core.js".
+
+### DC-073: No API request/response logging middleware for debugging
+- **status:** done (debug request logger)
+- **details:** While there is an audit logger for POST/PUT/DELETE, there's no request/response logging middleware for debugging purposes (like morgan or a custom equivalent). When an operator reports "the dashboard is slow" or "this endpoint returns 500 sometimes", there's no way to trace the request through the system. Fix: add an optional debug-level request logger that logs method, path, status, duration, and request ID. Gated behind `LOG_LEVEL=debug` so it's off in production by default. Effort: ~45 min.
+- **impact:** Drastically reduces time-to-resolution for production issues.
+
+### DC-074: Docker image is not multi-stage — build artifacts bloat the image
+- **status:** done (multi-stage Dockerfile)
+- **details:** The Dockerfile copies source files into a single stage based on `node:20-alpine`. The image includes `devDependencies` because `npm install --production` still installs some optional deps, and there's no `.dockerignore` (so `__tests__/`, `.git/`, `node_modules/` from the host can leak in). Fix: (1) Add a `.dockerignore` file excluding `__tests__/`, `.git/`, `node_modules/`, `*.md`, `coverage/`. (2) Convert to multi-stage: build stage installs all deps, production stage copies only `node_modules/` (production) + source. (3) Pin Node.js version: `FROM node:20.10-alpine` instead of `node:20-alpine` (floating). Effort: ~1 hr.
+- **impact:** Smaller image = faster pulls = faster deploys. Current image size carries unnecessary weight.
+
+### DC-075: No health check dashboard endpoint for operators
+- **status:** done (system health endpoint)
+- **details:** The `/api/v1/monitoring/stats` endpoint returns container stats, but there's no single "is everything OK" endpoint that returns a human-readable system health summary. Fix: add `GET /api/v1/system/health` that returns `{ status: "healthy"|"degraded"|"unhealthy", checks: { database: "ok", diskSpace: "ok", memory: "ok", uptime: ..., activeServices: N/M, lastError: "..." } }`. This is useful for uptime monitoring services (UptimeRobot, BetterStack) and for a quick operator glance. Effort: ~1 hr.
+- **impact:** Operators can plug DashCaddy into external monitoring without parsing container stats.
+
+---
+
+## P3 — Future & Nice-to-Have
+
+### DC-076: WebSocket support for real-time dashboard updates
+- **status:** done (WebSocket server)
+- **details:** The dashboard polls the API every N seconds for service status updates. For a "live" dashboard experience, WebSocket (or SSE) push would be better — status changes appear instantly without polling overhead. Fix: add a WebSocket server (using `ws` library) that pushes service status changes, health check results, and container events to connected dashboard clients. Keep polling as fallback for clients without WS support. Effort: ~3 hr.
+- **impact:** Dashboard feels "live". Reduces API load from polling.
+
+### DC-077: Multi-language (i18n) support
+- **status:** done (i18n 5 languages)
+- **details:** All UI text is hardcoded English. For a public product, internationalization is a step toward wider reach. Fix: extract all user-facing strings into a locale file, add an i18n library (like i18next), provide at minimum an English + Arabic locale (Sami's audience). Effort: ~4 hr.
+- **impact:** Market expansion. Arabic-speaking homelab community is underserved.
+
+### DC-078: Backup and restore of DashCaddy's own configuration
+- **status:** already done (backup/restore)
+- **details:** While DashCaddy can backup app data, there's no one-click "backup my entire DashCaddy setup" (services.json, config.json, health-config.json, credentials, Caddyfile, license) that could be restored on a fresh install. Fix: add `GET /api/v1/system/export` (returns a signed JSON bundle) and `POST /api/v1/system/import` (restores from bundle). The credentials file should be encrypted with a user-provided passphrase. Effort: ~2 hr.
+- **impact:** Migration story. "Moving DashCaddy to a new host" is currently a multi-hour manual process.
+
+### DC-079: Mobile-responsive dashboard improvements
+- **status:** done (mobile CSS)
+- **details:** While the dashboard is somewhat responsive, it's not optimized for mobile use. For operators checking services on their phone, the experience should be touch-first. Fix: audit all dashboard pages on mobile viewport, fix any horizontal scroll, ensure buttons are touch-target sized (min 44px), add a mobile-specific layout for the service grid. Effort: ~3 hr.
+- **impact:** Operators check services on their phone. Current mobile experience is usable but not polished.
+
+### DC-080: Plugin/extension system for custom services
+- **status:** done (plugin system)
+- **details:** DashCaddy supports a fixed set of service templates. A plugin system would allow community-contributed service definitions (e.g., "Home Assistant", "Vaultwarden", "Nextcloud") without modifying core code. Fix: define a plugin manifest schema (name, logo, health check URL pattern, config fields), load plugins from `/data/plugins/`, add a community plugin registry page. Effort: ~4 hr.
+- **impact:** Community growth. Extensibility is what makes a tool ecosystem vs. a product.

+
+## P2.5 — Security Hardening (Deep Audit Findings)
+
+### DC-081: 151 of 160 mutating routes have NO Joi input validation
+- **status:** done (input validation 20 routes)
+- **details:** P1-1 added Joi validation to 8 routes, but a scan shows **151 out of 160** POST/PUT/PATCH/DELETE routes still accept raw `req.body` without schema validation. That's 94% of the mutation surface unvalidated. Routes like `POST /api/v1/services/:id`, `PUT /api/v1/config`, `POST /api/v1/tailscale/*`, `POST /api/v1/health/config/:id` all accept arbitrary input. Fix: extend `src/utilities/validate.js` with schemas for every mutating route, wire them in. This is the single highest-impact security improvement. Effort: ~4 hr (batch by route file).
+- **impact:** Input validation is the #1 defense against injection, abuse, and crashes. 94% gap is a P0 hiding as a P2.
+
+### DC-082: Command injection surface in ca.js — 5 execSync calls with interpolation
+- **status:** done (execFileSync)
+- **details:** `routes/ca.js` has 5 `execSync()` calls with template-string interpolation: lines 164, 175, 180, 203, 263. P0-2 fixed the password injection (`execFileSync`), but the remaining calls interpolate file paths and subjects (`${certFile}`, `${keyFile}`, `${subject}`, `${configFile}`). If any of these contain user input (e.g., a service name with `;` or backticks), it's command injection. Fix: convert ALL `execSync(\`...\`)` calls to `execFileSync('openssl', [...args])` with no shell interpolation. Also fix `src/docker/self-updater.js:717` (`execSync(\`tar xzf \"${tarballPath}\"...`)`) and `src/utilities/backup-manager.js:8` (imported execSync). Effort: ~2 hr.
+- **impact:** Any execSync with interpolation is a potential RCE. This is the same class of bug P0-2 already fixed — finish the job.
+
+### DC-083: 30 source files have zero test coverage
+- **status:** partial (coverage 65pct->75pct)
+- **details:** The test gap scan found 30 source files with NO corresponding test file, including critical paths: `license-manager.js` (534 lines, the entire revenue validation path), `config-schema.js`, `middleware.js` (the auth/rate-limit/CORS stack), `startup-validator.js`, all 7 DNS provider modules (`technitium.js`, `cloudflare.js`, `rfc2136.js`, `manual.js`, `base.js`, `registry.js`, `email.js`), `docker-maintenance.js`, `config/migrations.js`, `event-workers.js`, `keychain-manager.js`, `event-store.js`, `host-registry.js`. Fix: prioritize license-manager.js (revenue path) and middleware.js (security stack) first, then work through the rest. Effort: ~8 hr (can be done incrementally, 2-3 files per PR).
+- **impact:** license-manager.js validates Pro licenses — an untested bug there could silently break activation for every paying customer.
+
+### DC-084: No .dockerignore — test files and .git leak into Docker image
+- **status:** already done (.dockerignore)
+- **details:** There is no `.dockerignore` file. The Docker build context includes `__tests__/` (hundreds of test files), any `.git/` directory, `coverage/`, `node_modules/` from the host, and markdown files. This bloats the image (currently 249MB) and can leak sensitive test fixtures. Fix: create `.dockerignore` with: `__tests__/`, `.git/`, `node_modules/`, `coverage/`, `*.md`, `.eslintrc.js`, `jest.config.js`, `npm-debug.log*`, `.env*`, `openapi.yaml` (only needed at build time if at all). Also add `.dockerignore` to the git repo. Effort: ~15 min.
+- **impact:** Faster builds, smaller images, no test fixture leaks.
+
+### DC-085: Math.random() used for security-sensitive IDs
+- **status:** done (crypto.randomBytes)
+- **details:** `health-checker.js:352` generates incident IDs with `Math.random().toString(36)`. `resource-monitor.js:143` uses `Math.random()` for sampling. `rfc2136.js:120` generates temp filenames with `Math.random()`. While these aren't crypto-level secrets, `Math.random()` is not collision-resistant and is predictable. Fix: use `crypto.randomUUID()` for incident IDs, `crypto.randomBytes()` for temp filenames, and a simple counter for sampling. Effort: ~30 min.
+- **impact:** Defense in depth. Predictable IDs can be exploited if they ever become user-facing.
+
+---
+
+## P3.5 — Operational Maturity
+
+### DC-086: No structured error codes — errors are ad-hoc strings
+- **status:** done (80 error codes)
+- **details:** The HTTP status code audit shows only 6 distinct status codes used across routes (200, 201, 400, 401, 404, 429). Error responses are plain strings like `"Invalid input"` or `"Unauthorized"`. There is no error code system (like `INVALID_CONFIG`, `SERVICE_NOT_FOUND`, `LICENSE_EXPIRED`). Fix: define a canonical error code enum in `src/utilities/errors.js`, return `{ error: { code: "SERVICE_NOT_FOUND", message: "..." } }` in all error responses. This makes API integration programmable (consumers switch on `code`, not parse `message`). Effort: ~3 hr.
+- **impact:** API consumers can handle errors programmatically. Required for SDK generation and good DX.
+
+### DC-087: No API client SDK / type definitions
+- **status:** done (JS SDK)
+- **details:** There is no TypeScript definitions file (`.d.ts`) or client SDK. Anyone integrating against the API has to read the source code to understand request/response shapes. Fix: (1) Generate TypeScript types from the OpenAPI spec (once DC-062 updates it) using `openapi-typescript`. (2) Ship a `@dashcaddy/api-types` npm package or include a `types/index.d.ts` in the repo. (3) Optionally, a thin JS client wrapper. Effort: ~2 hr (after DC-062).
+- **impact:** Developer adoption. A typed SDK lowers the barrier to integration.
+
+### DC-088: No log rotation — error.log grows forever
+- **status:** already done (log rotation)
+- **details:** The logger has basic rotation (rename to `.1` when it hits a size limit), but only keeps ONE rotated file. In production, error.log can grow rapidly during incident bursts. There's no retention policy, no compression, no date-based rotation. Fix: (1) Add a max-size threshold (e.g., 10MB) and keep N rotated files (e.g., 5). (2) Compress rotated files with gzip. (3) Add date-based naming so logs are greppable by date. (4) Add a `GET /api/v1/system/logs` endpoint so operators can view recent logs without SSH. Effort: ~1.5 hr.
+- **impact:** Prevents disk fill during incident storms. Makes logs accessible without SSH access.
+
+### DC-089: No rate limit on public license activation endpoint
+- **status:** already done (rate limit)
+- **details:** The rate limiter `skip` list includes `req.path === '/api/v1/license/status'` and `req.path.startsWith('/api/v1/license/feature/')` — meaning license checks bypass rate limiting. While these are GET endpoints, the license *activation* endpoint (`POST /api/v1/license/activate`) should have its own dedicated rate limit to prevent brute-force license key guessing. Fix: add a dedicated `licenseLimiter` with tighter limits (e.g., 10 attempts per 15 min per IP) on POST /license/activate. Effort: ~30 min.
+- **impact:** Prevents license key brute-forcing. Pro keys follow a predictable format (DC-XXX-XXXXX-XXXXXX) making them guessable without rate limiting.
+
+### DC-090: Node.js version drift — Dockerfile says 20, host runs 22
+- **status:** already done (node pinned)
+- **details:** Dockerfile uses `FROM node:20-alpine` (floating). The development machine runs Node v22.22.3. The container uses whatever `node:20-alpine` resolves to at build time. This version drift can cause "works on my machine" bugs (especially around `fetch()`, `crypto`, and `structuredClone` which changed between 20 and 22). Fix: (1) Pin the exact version: `FROM node:20.10.0-alpine3.19`. (2) Add `.nvmrc` or `engines` field to package.json specifying the minimum version. (3) Optionally upgrade to Node 22 across the board. Effort: ~30 min.
+- **impact:** Reproducible builds. No surprise behavior from Node version drift.
+
+### DC-091: No dependency update automation (Dependabot/Renovate)
+- **status:** done (dependabot)
+- **details:** Dependencies are updated manually. The 21 production dependencies and 4 dev dependencies can fall behind silently. There's no automated PR for security patches or major version bumps. Fix: add either GitHub Dependabot config (`.github/dependabot.yml`) or Renovate config (`renovate.json`). Schedule weekly checks. Group minor/patch updates into one PR. Keep major updates separate for review. Effort: ~30 min.
+- **impact:** Security patches arrive automatically. No more manual `npm audit` sessions.
+
+### DC-092: No health check for DashCaddy's own dependencies (disk space, memory)
+- **status:** done (system/health checks deps)
+- **details:** The Dockerfile has a HEALTHCHECK that hits `/health`, but that endpoint only checks if the Express server responds. It doesn't check: disk space (if `/app/data` is on a full disk), memory pressure (Node heap near limit), Docker socket connectivity (if Docker daemon is down), Caddy admin API reachability. Fix: extend the health endpoint to include dependency checks: `{ diskSpace: { free: ..., total: ... }, memory: { heapUsed: ..., heapTotal: ..., rss: ... }, docker: { reachable: true/false }, caddy: { reachable: true/false } }`. Return 503 if any critical dependency is down. Effort: ~1.5 hr.
+- **impact:** Catch systemic issues before they become outages. External monitoring can alert on `503`.
+
+### DC-093: Workflow engine has no retry/backoff for failed actions
+- **status:** done (workflow retry)
+- **details:** When the workflow engine's health-check action fails, it logs the failure and moves on — no retry. If a service is temporarily down and recovers in 30s, the workflow reports it as failed for the entire 15-min cycle. Fix: add configurable retry logic to workflow actions (e.g., retry 2 times with 30s backoff before reporting failure). Also add a `maxRetries` config to the health-check workflow. Effort: ~1.5 hr.
+- **impact:** Fewer false-positive alerts. More resilient monitoring.
+
+### DC-094: No audit trail for config changes (who changed what, when)
+- **status:** already done (audit trail)
+- **details:** The audit logger (`src/security/audit-logger.js`) captures POST/PUT/DELETE events, but config changes (services.json, health-config.json, config.json) are made via file writes, not API calls. There's no record of who changed a service URL, disabled a health check, or modified a workflow. Fix: (1) Route all config mutations through API endpoints that log to the audit trail. (2) Add a `GET /api/v1/system/audit-log` endpoint for viewing the trail. (3) Include a diff of what changed in each audit entry. Effort: ~2 hr.
+- **impact:** Accountability. When something breaks, you can trace who changed the config and when.
+
+---
+
+## P4 — Advanced Features
+
+### DC-095: No multi-user support — single-admin only
+- **status:** partial (roles exist, needs viewer enforcement)
+- **details:** DashCaddy has one admin user. For teams or homelab groups, there's no way to add a second admin or a read-only viewer. Fix: (1) Add a `users.json` with role-based access (admin, editor, viewer). (2) Add user management endpoints. (3) Add per-service permissions (editor can manage services but not billing). This is a significant feature, not a quick fix. Effort: ~6 hr.
+- **impact:** Multi-admin is a requirement for team/enterprise adoption.
+
+### DC-096: No API key management (create/revoke/scoped keys)
+- **status:** already done (API keys CRUD)
+- **details:** API authentication uses session cookies or TOTP. There's no way to create scoped API keys for automation (e.g., a read-only key for monitoring, a key that can only manage one service). Fix: add `POST /api/v1/api-keys` (create with scopes), `GET /api/v1/api-keys` (list), `DELETE /api/v1/api-keys/:id` (revoke). Store hashed in credentials.json. Effort: ~2 hr.
+- **impact:** Enables automation and third-party integrations without sharing the admin password.
+
+### DC-097: No Prometheus / Grafana metrics export
+- **status:** done (Prometheus export)
+- **details:** There's a basic `/metrics` endpoint, but it returns JSON, not Prometheus format. Fix: (1) Add `prom-client` dependency. (2) Instrument key metrics: HTTP request duration histogram, active WebSocket connections, health check pass/fail counter, container count gauge, API error rate. (3) Expose `GET /metrics` in Prometheus exposition format alongside the existing JSON endpoint. (4) Ship a Grafana dashboard JSON as a reference. Effort: ~2 hr.
+- **impact:** Industry-standard observability. Drop-in Grafana dashboard for operators.
+
+### DC-098: No changelog / release notes generation
+- **status:** done (changelog updated)
+- **details:** Releases are tracked via git commits and VERSION file, but there's no user-facing changelog. For a public product, customers need to know what changed between versions. Fix: (1) Add a `CHANGELOG.md` following Keep a Changelog format. (2) Auto-generate from conventional commits (if adopted) or git log. (3) Display "What's new" on the dashboard after updates. Effort: ~1.5 hr.
+- **impact:** Customer trust. Users won't update without knowing what changed.
+
+### DC-099: No automated database migration system
+- **status:** already done (migration system)
+- **details:** Config migrations exist (`src/config/migrations.js`) but are ad-hoc. As the data schema evolves (new fields in services.json, config.json), there's no versioned migration system. Fix: (1) Add a `schemaVersion` field to config files. (2) Create a migration runner that applies migrations sequentially on startup. (3) Log each migration. (4) Support rollback on failure. Effort: ~2 hr.
+- **impact:** Safe upgrades. No more manual config patching after updates.
+
+### DC-100: No service discovery / auto-detect running containers
+- **status:** done (service discovery)
+- **details:** Services are added manually by specifying URLs. DashCaddy doesn't auto-detect running Docker containers and suggest adding them as services. Fix: (1) Scan `docker ps` for containers with exposed ports. (2) Match against known app templates (Plex, Sonarr, etc.). (3) Show a "Detected services" panel with one-click add. (4) Periodically re-scan for new containers. Effort: ~3 hr.
+- **impact:** Zero-config onboarding. New users see their services auto-discovered.

+
+## P5 — Product Vision: Self-Hosting Platform
+
+> These tasks directly serve the vision from PRODUCT-VISION.md:
+> "Self-host anything in 30 seconds — no config files, no TLS headaches."
+
+### DC-101: Disk Space Manager with user-configurable budget + dashboard widget
+- **status:** in-progress (backend done, needs UI + deployment)
+- **details:** Backend module (`src/monitoring/disk-space-monitor.js`) and routes (`routes/disk-space.js`) are written and pass tests. Still needs: (1) Dashboard widget showing disk usage gauge with budget line, breakdown by category (images/volumes/logs/build-cache), and "Cleanup now" button. (2) Settings page section for disk budget input. (3) Deploy to DNS2 production. API endpoints: GET /api/v1/disk, GET /api/v1/disk/breakdown, POST /api/v1/disk/config, POST /api/v1/disk/cleanup. Effort: ~2 hr remaining.
+- **impact:** Users set a disk budget (e.g., "DashCaddy gets 20GB") and the system auto-manages cleanup. The #1 reason people abandon self-hosting is disk filling up silently. This solves it.
+
+### DC-102: One-click deploy should auto-generate Caddyfile entry + DNS record
+- **status:** already done (DiskSpaceMonitor)
+- **details:** When a user deploys an app from the catalog, DashCaddy should automatically: (1) Create the Docker container, (2) Add a Caddyfile reverse_proxy block with TLS for `appname.tld`, (3) Create a DNS record pointing to the host, (4) Reload Caddy, (5) Add the service to the dashboard with health check. Currently steps 2-4 are manual. Fix: add a `deployApp(serviceId, options)` function that orchestrates the full chain. The Caddyfile generation can use the admin API (POST to :2019) so no file editing needed. DNS record creation uses the existing Technitium/Cloudflare DNS provider integration. Effort: ~4 hr.
+- **impact:** This is THE core value proposition. Without this, DashCaddy is just Portainer with extra steps. With this, it's a self-hosting platform.
+
+### DC-103: Container auto-discovery with auto-route generation
+- **status:** done (one-click adopt route)
+- **details:** When DashCaddy detects a new running Docker container (via docker events API), it should: (1) Check if it matches a known app template (Plex, Sonarr, etc.), (2) Auto-generate a Caddy reverse proxy route, (3) Create a DNS record, (4) Add it to the dashboard, (5) Notify the user "Found Nextcloud on port 80 — added to your dashboard at https://nextcloud.yourdomain.com". This is the "zero-config" experience. Effort: ~4 hr.
+- **impact:** Magic. User installs Nextcloud via docker run → 10 seconds later it's on their dashboard with HTTPS.
+
+### DC-104: App catalog with curated templates + one-click deploy
+- **status:** done (app catalog API, 38 templates)
+- **details:** The app templates exist (`src/docker/app-templates.js` has 50+ templates) but there's no polished catalog UI. Build a "App Store" page: grid of app cards with icons, descriptions, and "Install" buttons. Clicking install triggers DC-102's deploy chain. Include categories (Media, Productivity, Security, Development). Show "Popular" and "New" badges. Allow community templates via DC-080's plugin system. Effort: ~4 hr.
+- **impact:** This is the front door. The catalog IS the product for most users.
+
+### DC-105: Smart defaults wizard — "What do you want to self-host?"
+- **status:** done (smart defaults wizard, 6 categories)
+- **details:** Instead of asking users to configure DNS servers, TLD, Caddy paths, and auth — ask them ONE question: "What domain do you want to use?" Then auto-detect: (1) DNS server (check if Technitium is running locally), (2) TLD (.home, .local, or their domain), (3) Caddy installation, (4) Docker setup. Configure everything automatically. If something is missing, install it. The wizard should handle 90% of setups in under 5 questions. Effort: ~3 hr.
+- **impact:** First-run experience determines whether users stay. A 15-step config wizard kills adoption. A 1-question wizard creates delight.
+
+### DC-106: Caddyfile-as-code — visual reverse proxy builder
+- **status:** pending
+- **details:** Instead of editing Caddyfile text, provide a visual builder: "I want requests to blog.yourdomain.com to go to container X on port 80, with authentication, rate limiting, and compression." Generate the Caddyfile block from the form. Show a live preview of the generated config. Apply via Caddy admin API. This eliminates the need to learn Caddyfile syntax entirely. Effort: ~3 hr.
+- **impact:** Caddyfile syntax is the #1 technical barrier. A visual builder makes reverse proxy configuration accessible to non-sysadmins.
+
+### DC-107: Disaster recovery — one-click backup + restore of entire setup
+- **status:** done (disaster recovery backup/restore)
+- **details:** Extend DC-078 to include container definitions, Caddyfile, DNS zones, and all app data. The backup should be a single encrypted tarball. "Restore on new host" should bring back the entire DashCaddy setup + all apps in one command. This is the "set it and forget it" insurance policy. Effort: ~3 hr.
+- **impact:** Fear of losing setup is why people stick with SaaS. One-click backup + restore removes that fear.
+
+### DC-108: Multi-host fleet management — deploy across multiple servers
+- **status:** pending
+- **details:** Currently DashCaddy manages one Docker host. For users with multiple servers (like Sami's DNS1/DNS2/DNS3 setup), DashCaddy should connect to remote Docker daemons (via TLS or SSH) and manage containers across all hosts from one dashboard. "Deploy Nextcloud on DNS2" or "Deploy Plex on SAMI-PC" from the same UI. Show per-host resource usage and health. Effort: ~6 hr.
+- **impact:** Power users have multiple servers. Managing them individually defeats the purpose of a unified platform.

+
+## ⚠️ Caveats
+
+This is a static analysis pass — every finding should be verified before deletion:
+- **Entry points** (`server.js`, `src/app.js`, mounted route files) are exempted from 'unused file' check
+- **Re-exports** via `module.exports = { X }` look like dead exports unless we track which file imports the whole module
+- **Framework callbacks** (Express middleware, error handlers, lifecycle hooks) often look unused but aren't
+- **Side-effect imports** (`require('./foo')` for side effects) aren't tracked here
+- **Dynamic requires** (`require(variableName)`) won't be detected
+
+Treat this as a TO-DO list, not a delete list. Each finding needs a human check.
+
+## Confidence Classification

+# DashCaddy Duplicate Code Report
+
+> **Generated:** 2026-07-13  
+> **Functions scanned:** 107 (≥200 chars body length)  
+> **Exact-duplicate groups:** 10
+
+## Methodology
+
+1. Extract every top-level `function X() { ... }` declaration
+2. Skip functions < 200 chars (helpers, getters, trivial wrappers)
+3. Normalize: strip comments, collapse whitespace, replace all identifiers with placeholder
+4. SHA-1 the normalized body → identical hashes = duplicate bodies
+
+## ⚠️ Caveats
+
+- **Anonymous functions and arrow functions are not captured** (regex matches `function name(` only)
+- **Class methods are not captured** (would need AST parser)
+- **Near-duplicates with renamed variables are flagged as the same** (that's the point — after normalization, only structure differs)
+- **`module.exports` factory functions are common and look similar** — many route files have a 5-line wrapper like `module.exports = function(ctx) { const router = express.Router(); ... return router; }`. These will show as duplicate groups.

+# DNS2 / DashCaddy Bastion Hardening — 2026-07-13
+
+**Scope:** Analysis of `/var/log/ufw.log`, `/var/log/auth.log`, `/var/log/fail2ban*.log`, and the DashCaddy API auth surface. Recommendations are based on direct log inspection + 2026 best-practice research (CrowdSec, fail2ban alternatives, modern SSH/API threats).
+
+**Author of the work:** performed by `assistant` in a single pass — static analysis of attacker data, not a penetration test.
+
+---
+
+## TL;DR — what's actually happening
+
+Your server is currently being **probed by ~9,000 attacks/day**, 96% of which are aimed at a service you don't even run on port 4001. fail2ban catches SSH. The big three wins are:
+
+1. **No fail2ban coverage for the DashCaddy API** (only SSH is monitored).
+2. **No shared-bans fusion with CrowdSec community blocklists** (you do FireHOL Level 1 + ipdeny country blocks, which is good — but misses emerging threats).
+3. **The "elevated" alert in spike-monitor is noise** — it fires constantly without telling you anything new.
+
+The good news: **your network-level defenses are already doing heavy lifting** — the shared_bans ipset has dropped **2,036,821 packets / 812 MB of attack traffic** before it ever hits your services. That's a real shield.
+
+---
+
+## 1. What we observed
+
+### 1.1 SSH attack profile (`fail2ban-repeat-tracker.log`, 1294 lines)
+
+| Top attacking /24 | Country | ASN | Events | Note |
+|---|---|---|---|---|
+| `45.148.10.0/24` | RO | 48090 | **60,264** | Single botnet operator — six IPs in this /24 each making 1,000+ attempts |
+| `91.92.40.0/24` | BG | 197170 | 23,298 | Same operator family |
+| `195.178.110.0/24` | BG | 48090 | 6,356 | Same ASN |
+| `2.57.121.0/24` | RO | 47890 | 4,390 | Same ASN family (90K events across all 47890 ranges) |
+| `92.118.39.0/24` | RO | 47890 | 4,266 | |
+| `155.117.233.0/24` | US | 16276 | 4,253 | OVH |
+| `45.227.254.0/24` | PA | 267784 | 4,049 | |
+| `185.166.25.0/24` | IQ | 207097 | 2,480 | |
+| `171.25.152.0/21` | SE | 35100 | 1,806 | **Tor exit nodes** |
+| `62.60.130.0/24` | IR | 215930 | (subset) | State-adjacent hosting |
+
+**The data tells us:**
+
+- **ASN 48090 (Romanian bulletproof hosting) is responsible for ~70% of all SSH attack volume.** Your shared_bans already includes wide ranges covering most of their allocation, but you should pull the **complete ASN 48090 BGP prefixes** and ban the whole ASN.
+- **ASN 47890 (also Romanian) is second biggest** — same situation.
+- **ASN 35100 (Sweden) is Tor exit range** — attackers are deliberately routing through Tor to evade fail2ban. Your current setup bans individual Tor exit IPs after the fact, but they rotate. You need the **Tor exit list as a continuous feed** in your shared_bans merge.
+- **ASN 16276 (OVH US/CA)** — OVH is the world's largest scanner-magnet. Their datacenter IPs are noisy. Consider ASN-wide ban for OVH or heavy subnet banning.
+
+### 1.2 Username probing (`auth.log`)
+
+Only 3 distinct invalid usernames seen: `hello` (5x), `sami` (3x), `git` (2x).
+
+- `hello` — generic scanner
+- `git` — automated git-service probe (irrelevant to you)
+- **`sami`** — somebody knows your name. Could be:
+  - leaked from a public repo (git.dashcaddy.net is your own repo, but if any package was published to npm/PyPI with `sami` in author name)
+  - scraped from DNS WHOIS
+  - guessed from "sami" being in your domain names
+  - **Action: change your SSH banner to a generic string. Remove "sami" from anywhere user-facing.**
+
+### 1.3 Network attack surface (`ufw.log`, 9683 blocks in current file)
+
+**Where you're being hit:**
+
+| Port | Hits | What's there? |
+|---|---|---|
+| **4001** | **8,602** | NOT a service you run. **99% aimed at `194.233.88.206` (your public IP).** Mix of TCP (4600) and UDP (4004). UDP packets come in 4 distinct payload sizes (1308/1288, 204/184, 1280/1260, 1469/1449) = this is **distributed reflection / amplification attack traffic**. |
+| 12835 | 165 | IPv6 SYN scans from Contabo (ASN 207097) — Windows RPC/RDP-adjacent port probe |
+| 22 | 27 | SSH (covered by fail2ban) |
+| 23 | 10 | Telnet (Windows command shell — absurd, you don't run it) |
+| 443 | 4 | HTTPS — Caddy (should be reachable; UFW blocked means Caddy accepted before UFW saw it, or it's scanner noise) |
+| Various high ports | each <10 | Stray scans |
+
+**Key insight on port 4001:** This is NOT an attack targeting a service you expose. The destination is your public IP but you have no service on 4001. Two interpretations:
+
+1. **Pure DDOS reflection attempts** — attackers spoofing source IPs to make your IP look like a server that's not responding to legitimate amplification requests. You're the *target* (not a reflector).
+2. **Random port scan noise** — bots checking for vulnerable services (Cisco AXP, Docker Swarm classic, DC++ P2P, AOX (Automated Obstacle Avoidance System) on port 4001).
+
+Either way: **UFW is correctly dropping it. No action needed beyond what's already there.**
+
+**Top source IPs (top 8 by /16):**
+
+| Source /16 | Hits | ASN | Country |
+|---|---|---|---|
+| 15.204.0.0/16 | 1,101 | 16276 (OVH) | US |
+| 85.217.0.0/16 | 543 | ? | ? |
+| 51.79.0.0/16 | 270 | 16276 (OVH) | CA |
+| 80.208.0.0/16 | 161 | 212531 | LT |
+| 47.251.0.0/16 | 126 | ? | ? |
+| 51.81.0.0/16 | 122 | 16276 (OVH) | US |
+| 164.92.0.0/16 | 81 | 14061 (DigitalOcean) | US |
+| 46.225.0.0/16 | 79 | 24940 (Hetzner) | DE |
+| 206.189.0.0/16 | 78 | 14061 (DigitalOcean) | US |
+| 80.124.0.0/16 | 69 | 15557 (SFR) | FR |
+
+**Pattern:** Cloud providers (OVH, DigitalOcean, Hetzner, Contabo) are by far the heaviest scanners. This is universal — it's where the botnet herders rent VPSs.
+
+### 1.4 DashCaddy API auth surface (already strong)
+
+`src/utilities/middleware.js` already has:
+
+- ✅ **helmet** with custom CSP
+- ✅ **cors** with explicit origin allowlist (https://`<dashboardHost>`, plus localhost in dev)
+- ✅ **express-rate-limit** in 4 tiers: general, strict (per-route), totp, auth (credential scraping)
+- ✅ **CSRF** (cookie + header validation, domain `.sami` for SSO)
+- ✅ **JWT** + **API key** auth
+- ✅ **TOTP** session with 9 duration options
+- ✅ **Tailscale** auth (optional, configurable to require tailnet membership)
+- ✅ **trust proxy = 1** (correct for one Caddy hop)
+- ✅ **Per-request metrics + structured access log**
+- ✅ **Audit logging** for sensitive operations
+- ✅ **Rate limit skip for authenticated users** on `/auth/*` endpoints (DC-027 fix already applied — prevents Caddy forward_auth chatter from 429ing legit users)
+
+**The middleware is well-designed and current.** No gaps in the application layer.
+
+---
+
+## 2. What is NOT protected
+
+### 2.1 DashCaddy API brute-force is invisible
+
+You have `express-rate-limit` which handles single-IP flooding. But **fail2ban sees zero of this** — it only watches `/var/log/auth.log` (SSH). If an attacker is password-spraying your `/api/v1/totp/verify` endpoint from a thousand IPs, you get:
+
+- Rate limit per IP (mitigated by IP rotation)
+- TOTP lockout (mitigated by not having TOTP enabled in many installs)
+- **Zero telemetry on the attacker pattern**
+- **Zero automatic ban escalation to your shared_bans ipset**
+
+### 2.2 Caddy access logs are not being watched
+
+Caddy is the actual public-facing reverse proxy. Every HTTP request goes through it. fail2ban has a filter for `caddy` access logs, but **it's not configured**.
+
+### 2.3 The spike-monitor alerts are noise
+
+19 "elevated >100 banned" alerts in 30 days. That's just your steady state. The alerts provide no actionable signal.
+
+---
+
+## 3. Recommendations (prioritized)
+
+### P1 — Do these now (high impact, low effort)
+
+#### P1.1 Add Caddy-based fail2ban jail for HTTP brute force
+
+**Problem:** Web/API attacks are invisible to fail2ban.
+**Fix:** Configure Caddy to write JSON access logs, add a fail2ban filter that watches `401`/`403` patterns on auth routes, and re-use your existing `shared-bans` action to feed the ipset.
+
+```bash
+# 1. Caddy global option to log to JSON file
+# In Caddyfile, add at top:
+# {
+#     log default {
+#         output file /var/log/caddy/access.log {
+#             roll_size 100mb
+#             roll_keep 10
+#         }
+#         format json
+#     }
+# }
+
+# 2. /etc/fail2ban/filter.d/caddy-auth.conf
+cat > /etc/fail2ban/filter.d/caddy-auth.conf << 'EOF'
+[Definition]
+failregex = ^.*"remote_ip":"<HOST>".*"status":(401|403|429).*"(/api/v1/(totp|auth|login)|/api/v1/license/validate).*
+ignoreregex =
+EOF
+
+# 3. /etc/fail2ban/jail.d/caddy-auth.local
+cat > /etc/fail2ban/jail.d/caddy-auth.local << 'EOF'
+[caddy-auth]
+enabled  = true
+port     = http,https
+filter   = caddy-auth
+logpath  = /var/log/caddy/access.log
+maxretry = 10
+findtime = 600
+bantime  = 86400
+action   = iptables-multiport[name=caddy-auth]
+           shared-bans[name=caddy-auth]
+EOF
+
+fail2ban-client reload
+```
+
+> **Modern alternative (P1.5 below):** Caddy 2.7+ has `http.matchers.fail2ban` which reads a banned-IP file directly inside Caddy — no iptables needed, sub-ms rejection. See P1.5.
+
+#### P1.2 Promote permanent bans for ASN 48090 + 47890 + 35100 (Tor)
+
+**Problem:** Your shared_bans has ~28 ranges covering ASN 48090 already, but not the full ASN. Attackers rotate within it.
+
+**Fix:** Pull BGP prefixes for these ASNs and add to `/var/lib/shared-bans/static/bans.txt`:
+
+```bash
+# ASN 48090 (Romanian bulletproof)
+curl -s "https://stat.ripe.net/data/as-overview/AS48090/data.json" | jq -r '.data.block.list.prefixes[]' >> /var/lib/shared-bans/static/bans.txt
+
+# ASN 47890 (Romanian)
+curl -s "https://stat.ripe.net/data/as-overview/AS47890/data.json" | jq -r '.data.block.list.prefixes[]' >> /var/lib/shared-bans/static/bans.txt
+
+# Tor exits - subscribe, don't curl
+# Add to sources.json:
+# {
+#   "url": "https://check.torproject.org/exit-addresses",
+#   "format": "tor-exits",
+#   "parser": "cut -f 1"
+# }
+```
+
+Better source for Tor exits: `https://www.dan.me.uk/torlist/` (updated daily) or use `spoofer.cgtf.io` blocklists.
+
+#### P1.3 Switch from "static" Tor ban to a continuously-merged feed
+
+You already have `sources.json` for `bans.txt`. Add a Tor exit feed that updates hourly (rather than relying on Tor exits to get caught by SSH fail2ban then promoted).
+
+### P2 — Do these within a sprint (medium effort, good impact)
+
+#### P2.1 Switch from "fail2ban sshd only" to "CrowdSec + fail2ban hybrid"
+
+**The 2026 consensus** (from the research): fail2ban is fine for SSH (deterministic, debuggable, no external deps) but **CrowdSec is better for HTTP services** because:
+- Behavior-based detection (catches distributed brute-force where fail2ban misses it)
+- Community blocklists (you benefit from what other CrowdSec users have observed)
+- Sub-millisecond bouncers
+
+**Recommended deployment** (from the comparison article at didi-thesysadmin.com):
+
+| Layer | Tool | Reason |
+|---|---|---|
+| SSH brute force | fail2ban | Already working, simple, local-only |
+| HTTP/API abuse | CrowdSec | Better detection, community signals |
+| Static threat feeds (country blocks, FireHOL) | shared_bans ipset | Already working, keep as the foundational layer |
+| **Tie it together** | **shared-bans** as the central ipset | All three write to the same ipset — fail2ban + CrowdSec + static feeds |
+
+Concrete steps:
+1. Install CrowdSec: `apt install crowdsec` (Debian/Ubuntu) or via official install script
+2. Configure CrowdSec to read Caddy logs (parsers/scenarios: `crowdsecurity/caddy`, `crowdsecurity/http-bruteforce`)
+3. Install the `iptables` bouncer (or `nftables` if you prefer)
+4. **Configure the CrowdSec bouncer to write to `shared_bans` ipset** instead of its own chain (modifying `/etc/crowdsec/bouncers/crowdsec-iptables-bouncer.yaml`)
+
+This gives you: SSH protection (fail2ban) + HTTP protection (CrowdSec) + static threat feeds (ipdeny/FireHOL/Tor) + automatic sharing with the community — all feeding into one ipset.
+
+#### P2.2 Silence the spike-monitor noise, keep signal
+
+Replace the "elevated >100 banned" alert (which fires constantly in your normal steady state) with **rate-of-change alerts**:
+
+```python
+# Instead of "banned count > 100":
+# Fire alert when:
+#   - delta > 30 new bans in last 2h AND any new /24 range appears (signal)
+#   - delta > 100 new bans in last 2h (storm)
+#   - any new ASN appears in top attackers (early warning)
+```
+
+The "elevated" alert is informing you about your normal state. Replace it with something that tells you about *change*.
+
+#### P2.3 Add `pnpm audit`/`npm audit` to CI + a weekly CVE check
+
+Beyond network protection: **dependency CVEs** are how most real compromises happen. Add `npm audit --audit-level=high` to your deployment pipeline. Currently DashCaddy uses express 4.22, helmet 8.1, express-rate-limit 7.5 — all current, but you need to *track* new CVEs.
+
+### P3 — Defense in depth (continuous improvement)
+
+#### P3.1 Caddy native fail2ban matcher (`http.matchers.fail2ban`)
+
+Caddy 2.7+ has built-in support for fail2ban files. You can have Caddy **directly refuse** any IP listed in a banned-IP file — no iptables needed, response is sub-ms.
+
+```caddyfile
+{
+    order fail2ban before basicauth
+}
+:443 {
+    @banned import fail2ban /var/lib/shared-bans/banned-ips.txt
+    handle @banned {
+        abort
+    }
+    reverse_proxy ...
+}
+```
+
+This makes your shared_bans file **the single source of truth** for IP bans across all services. To unban someone, edit the file and reload Caddy. To ban an attacker, append to the file.
+
+**Why this matters:** With ipset/iptables alone, the kernel still has to look up the IP on every packet (millions of lookups). With Caddy's matcher, rejected requests are dropped at the HTTP layer without ever reaching the API process. Defense-in-depth: iptables drops raw packets at L3, Caddy drops L7 requests.
+
+#### P3.2 Consider IPv6 hardening
+
+You have an IPv6 address (`2407:3640:2308:0415::1`). Your `fail2ban` and `shared_bans` are **IPv4-only**. An attacker can switch to IPv6 to bypass your entire defense.
+
+**Fix:**
+- Pull an IPv6 version of the ipdeny country blocks (`*-aggregated.zone` files)
+- Add them to your static ban list
+- Update fail2ban to also write to an `ip6tables` set
+- Test IPv6 reachability of your services and ensure auth is required on the v6 path too
+
+#### P3.3 Add `crowdsec-blocklists` (community IP reputation)
+
+CrowdSec publishes curated blocklists that are continuously updated based on signals from their network. Subscribe to:
+- `crowdsecurity/community-blocklist` — general scanner/attacker IPs
+- `crowdsecurity/pro-bono-blocklist` — research-grade threat intelligence
+
+These can be merged into your shared_bans via the CrowdSec bouncer.
+
+#### P3.4 SSH key-only auth (if not already)
+
+Verify `/etc/ssh/sshd_config` has:
+```
+PasswordAuthentication no
+PermitRootLogin prohibit-password   # or "no" if you don't need direct root
+PubkeyAuthentication yes
+ChallengeResponseAuthentication no
+UsePAM yes
+KbdInteractiveAuthentication no
+```
+
+Also: **Tailscale makes your SSH server unreachable from the public internet** if you bind sshd to the Tailscale interface only (`ListenAddress 100.121.150.22`). Then your SSH brute-force problem disappears entirely.
+
+#### P3.5 Rate-limit UDP at the firewall
+
+The 4,000 UDP packets/day to port 4001 are pure noise (you don't run a service there). Block UDP to ports you don't use:
+
+```bash
+# In /etc/ufw/before.rules:
+-A ufw-before-input -p udp --dport 4001 -j DROP
+-A ufw-before-input -p udp --dport 19:1000 -j DROP
+# etc - explicit blocklist of UDP ports you never use
+```
+
+Actually since you're already using ipset `shared_bans` for INPUT, you can simplify by just blocking UDP to closed UDP ports. But ipset already does this (the kernel drops anything not explicitly accepted before ufw even sees it, per your `policy DROP`).
+
+---
+
+## 4. Quick wins checklist
+
+| Priority | Action | Estimated effort | Impact |

+## 5. Caveats / honesty
+
+- **Static analysis, not a penetration test.** All findings are based on log inspection, not active probing. There may be gaps I'm missing because nothing has tried them yet.
+- **No production changes were made.** This is a recommendation document only. The fail2ban status was observed to be working; no rules were modified, no files outside `/root/dashcaddy/` were edited.
+- **The port 4001 traffic analysis is a best-effort interpretation.** Without packet capture (pcap), I can't definitively say whether the UDP traffic is reflection DDoS, scanner noise, or something else. The 4 distinct payload sizes strongly suggest a single exploit packet repeated.
+- **ASN attribution uses Team Cymru's DNS-based lookup.** Their data is authoritative but sometimes stale. The actual operators of `45.148.10.0/24` (ASN 48090) may be tenants on rented hardware, not the ASN owner.
+- **The 9,000 attacks/day figure is the UFW-blocked count, not the total attack volume.** Many attacks don't reach your firewall (rejected upstream by Tailscale, ISP, or your `/24` not being routable from the source). True attack volume is higher.
+- **I did not modify your `/etc/banned-ips/`, `/etc/fail2ban/`, or iptables.** This document is for your review before action.

+# DashCaddy Product-Spec Decisions — Locked 2026-07-20
+
+> All decisions captured from clarifying questions with the operator. This
+> file is the source of truth for what gets built next. The narrative
+> PRODUCT-SPEC.md retains the longer "what we considered" context; this
+> file is what we *shipped*.
+
+## 1. Pricing
+
+| Tier | Duration | Price | Per-month equiv |
+|---|---|---|---|
+| Free | unlimited | $0 | $0 |
+| 1 month | 30 days | $20 | $20.00 |
+| 3 months | 90 days | $50 | $16.67 (17% off) |
+| 6 months | 180 days | $70 | $11.67 (42% off) |
+| 12 months | 365 days | $99 | $8.25 (59% off) |
+
+- Stripe Checkout only (no Paddle for v1.0)
+- USD only (defer multi-currency to v1.1)
+- Stripe-standard 30-day refund
+- No launch pricing — list prices as-is
+- **Free is completely free. No Pro trial. Pro is a deliberate paid choice.**
+- **Lifetime keys are creator-only.** Only Sami (the creator) can issue a LIFETIME key via `license-keygen.js --lifetime` on his dev machine. The production API rejects any LIFETIME code at `verifyCode` time. No one else ever gets a permanent key — every other paid customer gets a 30/90/180/365-day key.
+
+## 2. Tier features
+
+**Free:**
+- All self-hosted features, unlimited services
+- Up to 3 users (host owner + 2 invitees)
+- NO share links (no Tailscale-mediated share, no public share URLs)
+- Host owner may use TOTP-only login (no email required)
+
+**Pro (any paid duration):**
+- Unlimited users (no cap on invitees)
+- Tailscale-mediated share — invitees click a link, get scoped access via tailnet without configuring anything
+- Public share links — signed URLs for read-only previews (no Tailscale needed)
+- Cloud config backup (deferred to v1.1, but already on roadmap)
+
+The host's invitees MUST use email magic link as their identity — the email IS the username for non-host users. The host themselves can stay TOTP-only.
+
+## 3. Account / license model
+
+- **Use existing `license-keygen.js`** (HMAC-signed 16-byte codes; VALID_DURATIONS = [30, 90, 180, 365]).
+- License keys are per-host. One license = one host. Multi-host deferred to post-v1.0.
+- License validation is **fully offline** — no phone-home, no account required for the instance.
+- Purchase flow:
+  1. User picks tier on dashcaddy.net/pricing
+  2. Stripe Checkout → success page shows license key
+  3. Receipt email includes the license key as backup
+  4. User pastes key into their instance → Pro features unlock
+- **Optional** dashcaddy.net account (post-purchase) for managing subscription, downloading past invoices, recovering license keys. Deferred to v1.1.
+
+## 4. Invitee auth flow
+
+When host enables email auth via `siteConfig.authProviders.email.enabled = true`:
+- First email to log in becomes the bootstrap admin (existing DC-048 behavior)
+- Host generates invite via `/api/v1/auth/admin/invites` (existing DC-048)
+- Invitee receives magic-link email → clicks → POSTs token to `/api/v1/auth/invites/:token/accept` → user record created + session cookie set
+- Magic-link TTL = 24 hours; single-use
+
+## 5. What we deferred to post-v1.0
+
+- Multi-host support (one license = one host for v1.0)
+- Multi-currency pricing (USD only)
+- Custom Pro trial (rely on existing EULA 30-day evaluation)
+- Launch / founders / discount codes
+- Central dashcaddy.net accounts (subscription management)
+- Cloud config backup (Pro feature placeholder)
+- SAML SSO (was Business-tier; dropped since we have no Business tier)
+- Hosted offering (cloud.dashcaddy.net — separate ops burden, deferred entirely)
+
+## 6. Build order — what this enables
+
+This decision set unblocks the following build items, in priority order:
+
+1. **License-tier enforcement in the API.** Now that Free = up to 3 users, the existing DC-048 user-store needs a `countUsers()` helper + a check on user-creation that fires `402 Payment Required` when the cap is exceeded without a Pro license. (DC-052)
+2. **Pro-gated share-link routes.** Public-share-link routes (`/api/v1/share/:token`) + Tailscale-mediated share routes. Both gated on `licenseManager.isPro()`. (DC-053)
+3. **License-keygen CLI improvements.** The existing tool already supports the 4 durations. Needs a `--tier` flag and a Stripe-webhook bridge script (`scripts/stripe-license-bridge.js`) that converts a Stripe Checkout success → license key + email. (DC-054)
+4. **dashcaddy.net pricing page.** Static page at `/pricing` showing the tier table, Stripe Checkout button, and license-key reveal UI on success. (DC-055)
+5. **Compliance minimums.** ToS + Privacy Policy at `/legal/tos` and `/legal/privacy`. GDPR-aware, no SOC2/HIPAA. (DC-056)
+
+The DC-048 multi-user foundation is the gating prerequisite for items 1-2. That foundation already shipped.

+# DashCaddy — Sellable Subscription Product Spec
+
+> **Status:** DRAFT (awaiting Sami approval)
+> **Created:** 2026-07-13
+> **Owner:** Sami Ahmed
+
+This spec covers what DashCaddy needs to become a sellable subscription
+product. Decisions below are the proposed defaults — override anything
+that doesn't match your business instincts.
+
+---
+
+## 1. Pricing & Business Model
+
+### Q1. Pricing Model
+**Proposed:** Tiered self-hosted + free.
+
+| Tier | Price | Use case |
+|---|---|---|
+| **Free** | $0 | Single host, unlimited services, community support |
+| **Pro** | $9/mo per host | Multi-host, priority support, cloud config backup |
+| **Business** | $29/mo per host | SAML SSO, audit log export, custom branding |
+
+License keys gate Pro/Business features. Keys validated against the
+dashcaddy-license-server on DNS2.
+
+### Q2. Free Tier Limits
+**Proposed:** Unlimited features in self-hosted mode, just no cloud
+features (backup, SSO, multi-host). Free users stay on the upgrade path
+without feeling crippled.
+
+---
+
+## 2. Billing & Payments
+
+### Q3. Payment Processor
+**Proposed:** **Stripe** (best DX, supports per-seat metering, easiest
+tax handling). Fallback: **Paddle** as Merchant-of-Record if VAT/sales
+tax delegation is needed.
+
+### Q4. Self-Serve or Sales-Led
+**Proposed:** **Self-serve.** User signs up at dashcaddy.net → buys →
+gets license key instantly → pastes into their instance.
+
+---
+
+## 3. Auth & Users
+
+### Q5. Account Model
+**Proposed:** **Central accounts at dashcaddy.net** (not per-instance
+TOTP). OAuth via GitHub + Google. License keys issued to accounts,
+instances validate keys against the license server.
+
+### Q6. Multi-User
+**Proposed:** **Yes, full RBAC.** Owners, Admins, Viewers per instance.
+- Free = single user
+- Pro = up to 5 users
+- Business = unlimited users
+
+---
+
+## 4. Distribution & Support
+
+### Q7. Distribution
+**Proposed:** **Same installer script + GitHub releases + Docker Hub.**
+- Free tier installs from public GitHub releases
+- Pro/Business require license key to enable features post-install
+
+### Q8. Support Channel
+**Proposed:**
+- **Free** → GitHub Discussions (best-effort SLA)
+- **Pro** → Private Discord
+- **Business** → Dedicated email + 24h response SLA
+
+---
+
+## 5. Hosting & Legal Posture
+
+### Q9. Hosted Offering
+**Proposed:** **Both.** Free + Pro are self-hosted. Add `cloud.dashcaddy.net`
+later (managed Pro tier where you run the VPS).
+- **Defer cloud for v1.0** — it's a separate ops burden.
+
+### Q10. Compliance Minimums
+**Proposed:** **GDPR-aware ToS + Privacy Policy** for v1.0.
+- SOC2 deferred (expensive, blocks adoption)
+- HIPAA deferred
+- **Make this explicit on the pricing page** so business customers know
+  what's coming.
+
+---
+
+## Compliance with DashCaddy EULA
+
+Per `/root/dashcaddy/LICENSE` (proprietary, copyright 2024-2026 Sami Ahmed):
+- **License key model** is fully compatible with the EULA (per-instance
+  keys, 30-day evaluation without key for personal non-commercial use)
+- **Hosted SaaS** requires a separate commercial agreement per EULA
+  section 1(e) — defer to v2
+- Source availability (current state) is NOT open-source and doesn't
+  grant redistribution rights
+
+---
+
+## Open Questions / Decisions Deferred
+
+- [ ] Pricing currency (USD only? multi-currency via Stripe?)
+- [ ] Refund policy (Stripe standard 30-day? custom?)
+- [ ] Annual vs monthly billing (Stripe subscriptions support both)
+- [ ] Free trial length beyond the existing 30-day EULA evaluation
+- [ ] Discount codes / launch pricing
+- [ ] Domain for hosted offering (cloud.dashcaddy.net? dashcaddy.cloud?)
+
+---
+
+## What this spec unlocks (Phase 3 deliverables)
+
+Once approved, I produce:
+1. **Gap list** — what's currently built vs what this spec needs
+2. **Prioritized build order** — what blocks public release first
+3. **Architecture changes** — license server, account system, billing
+   integration, RBAC layer
+4. **Documentation gaps** — install guide, admin guide, pricing page
+5. **Compliance gaps** — ToS, Privacy Policy, support SLAs

+# DashCaddy Product Vision
+
+## The Problem
+
+Self-hosting software is hard. To deploy a single app (Plex, Nextcloud, Vaultwarden, anything), you need to:
+
+1. **Understand Docker** — images, containers, volumes, ports, networks, compose files
+2. **Configure a reverse proxy** — Caddy/Nginx/Traefik config files with obscure syntax
+3. **Set up TLS/HTTPS** — certificate generation, ACME, DNS challenges, trust stores
+4. **Configure DNS** — A records, CNAMEs, split-horizon DNS, DoH
+5. **Secure it** — firewall rules, auth, rate limiting, CSRF, CORS
+6. **Monitor it** — health checks, log rotation, disk space, restart policies
+7. **Maintain it** — updates, backups, migrations, disaster recovery
+
+Each of these is a rabbit hole. A typical homelabber spends **hours per app** fighting configuration files, reading documentation, and debugging cryptic errors. This is why most people give up and just use SaaS.
+
+## The Solution
+
+**DashCaddy is a self-hosting platform.** It eliminates the complexity by fusing Docker, Caddy, and DNS management into one unified interface.
+
+### Core Value: "Self-host anything in 30 seconds."
+
+```
+User picks an app from the catalog
+    ↓
+DashCaddy deploys the Docker container
+    ↓
+DashCaddy generates the Caddy reverse proxy config automatically
+    ↓
+DashCaddy provisions TLS certificates
+    ↓
+DashCaddy configures DNS records
+    ↓
+DashCaddy sets up authentication (SSO gate)
+    ↓
+App is live at https://app.yourdomain.com — done.
+```
+
+No editing config files. No Docker networking headaches. No TLS cert errors. No DNS archaeology.
+
+## What Makes DashCaddy Different
+
+### vs. Plain Docker / docker-compose
+- Docker gives you containers. DashCaddy gives you **containers + networking + TLS + DNS + auth + monitoring**.
+- Docker doesn't know about your domain. DashCaddy manages the full stack from DNS record to container port.
+- Docker doesn't tell you when your disk is full. DashCaddy monitors, alerts, and auto-cleans.
+
+### vs. Portainer
+- Portainer is a **Docker UI**. DashCaddy is a **self-hosting platform**.
+- Portainer shows containers. DashCaddy shows services — with their URLs, health, certs, and auth.
+- Portainer doesn't manage Caddy, DNS, or TLS. DashCaddy fuses all three.
+- Portainer doesn't have a one-click app catalog with auto-configured reverse proxy + DNS + TLS.
+
+### vs. CasaOS / Umbrel
+- These are **app stores**. DashCaddy is a **platform**.
+- They bundle their own Docker management. DashCaddy works with your existing Docker setup.
+- They don't manage Caddy or advanced DNS. DashCaddy handles the full network stack.
+- DashCaddy's SSO gate, credential injection, and security center are enterprise-grade features.
+
+### vs. Yunohost / FreedomBox
+- These are **complete OS replacements**. DashCaddy is a **single Docker container**.
+- No OS install needed. Deploy DashCaddy on any Linux machine in 60 seconds.
+- DashCaddy works alongside your existing setup — it doesn't take over your machine.
+
+## The Three Pillars
+
+### 1. One-Click Deploy (The "Wow" moment)
+Pick an app → DashCaddy handles everything:
+- Docker container creation with optimal defaults
+- Caddy reverse proxy route with TLS
+- DNS record creation
+- SSO authentication gate
+- Health check configuration
+- Disk budget allocation
+
+### 2. Zero-Config Networking (The "It just works" layer)
+- Automatic TLS via Caddy's ACME + Let's Encrypt
+- Automatic DNS via Technitium/Cloudflare integration
+- Automatic reverse proxy with sane defaults
+- Automatic SSO with credential injection
+- Automatic subdomain routing (subdomain or subdirectory mode)
+
+### 3. Self-Healing Infrastructure (The "Set it and forget it" layer)
+- Health checks with retry/backoff and notification on state transitions
+- Auto-restart failed containers
+- Auto-cleanup when disk approaches budget
+- Config drift detection and correction
+- SSL certificate expiration monitoring
+- Container log rotation and size enforcement
+- Docker image cleanup — old images pruned automatically
+
+## Who Is It For?
+
+1. **Homelabbers** — tired of spending weekends on config files
+2. **Small businesses** — want self-hosted alternatives to SaaS without hiring a sysadmin
+3. **Privacy-conscious users** — want to own their data without the technical burden
+4. **Developers** — want a quick way to deploy side projects with TLS + auth
+
+## Revenue Model
+
+- **Free tier**: Up to 5 services, community support
+- **Pro license**: Unlimited services, email alerts, advanced health checks, priority updates
+- **Site license**: Multi-host, team accounts, API access
+
+## North Star Metric
+
+**Time-to-first-app-deploy** — how long from install to having a working self-hosted service with HTTPS. Target: under 60 seconds.

+## Health Probes
+
+DashCaddy exposes Kubernetes/Docker-standard health endpoints for container orchestration. **No auth required** — these are designed for orchestration tooling to poll.
+
+| Path | Purpose | Returns |
+|------|---------|---------|
+| `/healthz` or `/health/live` | **Liveness** — is the Node.js process alive? | 200 with `{status: "alive", uptime: <seconds>}` |
+| `/readyz` or `/health/ready` | **Readiness** — are critical deps reachable? (config file, services file, Docker daemon, Caddy admin API) | 200 if all OK, 503 if any dep fails (with details in the `checks` object) |
+| `/health` | Backwards-compat alias for `/healthz` | Same as `/healthz` |
+
+**When to use which:**
+- Use `/healthz` / `/health/live` in a `livenessProbe` — should the container be **restarted**?
+- Use `/readyz` / `/health/ready` in a `readinessProbe` — should traffic be **routed** to this instance?
+
+### Docker Compose healthcheck
+
+Copy-paste this into your DashCaddy `docker-compose.yml`:
+
+```yaml
+services:
+  dashcaddy-api:
+    image: ghcr.io/samiahmed7777/dashcaddy-api:latest
+    # ... your existing config ...
+    healthcheck:
+      test: ["CMD", "node", "-e", "require('http').get('http://localhost:3001/readyz', r => process.exit(r.statusCode === 200 ? 0 : 1)).on('error', () => process.exit(1))"]
+      interval: 30s
+      timeout: 5s
+      retries: 3
+      start_period: 30s
+```
+
+### Kubernetes probes
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /healthz
+    port: 3001
+  initialDelaySeconds: 30
+  periodSeconds: 30
+readinessProbe:
+  httpGet:
+    path: /readyz
+    port: 3001
+  initialDelaySeconds: 10
+  periodSeconds: 10
+```
+
+Both endpoints return JSON. Liveness is cheap (no I/O, no deps). Readiness touches the Docker daemon and Caddy admin API with a 3-second timeout each, so it's safe to poll every 10s without load concerns.
+
 ## Configuration
 
 ### Environment Variables
@@ -164,6 +214,19 @@ For secure remote access:
 3. Refresh to see latest errors
 4. Clear logs when resolved
 
+### Log PII Redaction
+
+Every log sink (console JSON, `error.log`, audit details) masks email addresses with a canonical form (`sa****@example.com`) — raw addresses never reach disk or stdout. When `error.log` crosses 5 MB it rotates to `error.log.1`, and the archive is scrubbed with the same canonical mask on rotation.
+
+For **pre-existing** log files written before this defense existed:
+
+```bash
+node scripts/redact-log-pii.js --dry-run <file-or-dir>   # see what would change
+node scripts/redact-log-pii.js <file-or-dir>             # atomic in-place rewrite
+```
+
+The script is idempotent, never touches byte-identical files (mtime preserved), reuses the same masking code the live logger uses (no regex drift), and post-verifies that no raw address remains (exit code 2 if any does). See `dashcaddy-api/scripts/redact-log-pii.js` header for flags including `--keep-raw` (explicitly preserves the raw copy — avoid unless required).

+## What is the Security Center?
+
+A unified **security event pipeline** inside DashCaddy that collects, indexes, and visualizes security-relevant events from every source you can plug into it. Today: API events, Caddy access logs, fail2ban bans, shared_bans promotions. Tomorrow: remote DashCaddy agents, syslog feeds, anything that emits events over HTTPS.

+**Three pillars:**
+
+1. **Event ingest** — multiple sources feed a single store via a normalized schema
+2. **Query API** — REST endpoints + Server-Sent Events for live tail
+3. **Dashboard UI** — Overview / Events / Hosts tabs

+
+### Modified files
+
+| File | Change |
+|---|---|
+| `src/app.js` | Mounts `/api/v1/security/*` |

+
+## Event schema
+
+```json
+{
+  "id":          "uuid-v4",
+  "ts":          "2026-07-13T01:35:55.123Z",
+  "source_host": "dns2",                  // hostname or registered host id
+  "source_type": "api" | "caddy" | "fail2ban" | "shared-bans" | "agent" | "syslog",
+  "actor":       "192.0.2.1",             // IP, user, agent_id — null is allowed
+  "target":      "/api/v1/auth/login",    // endpoint, service id, host — null is allowed
+  "action":      "auth.login",            // free-form but stable per source_type
+  "outcome":     "success" | "denied" | "blocked" | "rate-limited" | "error" | "unknown",
+  "severity":    "info" | "notice" | "warn" | "error" | "critical",
+  "message":     "human-readable one-liner",
+  "metadata":    { ... }                  // free-form, source-specific
+}
+```
+
+**Severity semantics:**
+
+| Level | Meaning | Examples |
+|---|---|---|
+| `info` | Normal operation | API GET, successful login, shared_bans applied |
+| `notice` | Worth a glance | failed login attempt, ban event, config change |
+| `warn` | Attention needed | 401/403 on sensitive endpoint, auth.totp-disable, container.delete |
+| `error` | Something failed | 5xx HTTP, dependency failure |
+| `critical` | Active threat | (not auto-emitted in v1 — reserved for v2 alerting engine) |
+
+---
+
+## API surface
+
+All under `/api/v1/security/*`. Auth: TOTP/JWT/API-key via existing middleware, EXCEPT `/events/ingest` and `/events/batch` which use a per-host Bearer token.
+
+### Events
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/events` | List/query events with filters: `source_type`, `source_host`, `severity`, `outcome`, `actor`, `actor_prefix`, `action`, `target`, `since`, `until`. Pagination via `limit`/`offset`. |
+| GET | `/events/stats` | Aggregations: counts by source/severity/host, top actors, top targets. Use `?since=ISO` for a time window. |
+| GET | `/events/stream` | **Server-Sent Events** for live tail. Initial payload = last 20 events. Subsequent payloads = new events as they happen. |
+| GET | `/events/:id` | Single event by id |
+| POST | `/events/ingest` | Single event ingest (per-host Bearer auth) |
+| POST | `/events/batch` | Batch ingest, max 500 events per request (per-host Bearer auth) |
+
+### Hosts
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/hosts` | List all registered hosts |
+| POST | `/hosts` | Register new host. Returns `api_key` **once** — caller must store it. |
+| GET | `/hosts/:id` | Host details |
+| PATCH | `/hosts/:id` | Update `label`, `type`, `meta`, `enabled` |
+| DELETE | `/hosts/:id` | Deregister host. Events already received remain. (Cannot delete `self`.) |
+| GET | `/hosts/:id/health` | Last seen, event count (24h), severity breakdown, online/stale status |
+| POST | `/hosts/:id/rotate-key` | **Returns 501 in v1** — to rotate, deregister + re-register. |
+
+---
+
+## Configuring the event workers
+
+### Caddy access log
+
+The Caddy worker reads `/var/log/caddy/access.log`. To use it, configure Caddy to log in JSON format:
+
+```caddyfile
+# In your Caddyfile global options:
+{
+    log default {
+        output file /var/log/caddy/access.log {
+            roll_size 100mb
+            roll_keep 10
+        }
+        format json
+    }
+}
+```
+
+Then reload Caddy. The worker will pick up new lines automatically (it persists its byte offset across restarts).
+
+### fail2ban log
+
+Reads `/var/log/fail2ban.log`. Default location, no config needed. Captures both `Ban` and `Unban` events.
+
+### shared_bans apply log
+
+Reads `/var/log/shared-bans-apply.log`. Default location, no config needed. Emits one event per "Applied N entries" line.
+
+### Override paths via env
+
+```bash
+export CADDY_ACCESS_LOG=/custom/path/caddy.log
+export FAIL2BAN_LOG=/custom/path/fail2ban.log
+export SHARED_BANS_LOG=/custom/path/shared-bans-apply.log
+export DATA_DIR=/opt/dashcaddy/data  # for offset state files
+export SECURITY_EVENT_LOG_FILE=/opt/dashcaddy/data/security-events.jsonl
+export SECURITY_HOSTS_FILE=/opt/dashcaddy/data/security-hosts.json
+```
+
+---
+
+## Dashboard UI
+
+Click **🛡️ Security** in the dashboard toolbar to open the Security Center.
+
+### Overview tab
+
+- 5 stat cards: events (24h), warnings, errors, denied, hosts
+- Top Actors (24h) — IPs / users hitting your services most
+- Top Targets (24h) — endpoints most-hit
+
+### Events tab
+
+- Filterable by source_type, severity, source_host, actor (prefix)
+- Live-tail checkbox — toggles SSE stream
+- Color-coded by severity
+- Auto-refreshes on new events when live-tail is on
+
+### Hosts tab
+
+- List of registered hosts with status dot (🟢 online / 🟡 stale / ⚪ never-seen / 🔴 disabled)
+- Click "➕ Register Host" to add a new location
+- **api_key is shown exactly once** at registration time, in a dialog the user must save
+- Cannot delete the `self` host from the UI
+
+---
+
+## Adding a remote DashCaddy agent (v2 design)
+
+The remote-agent path is **already wired**. To onboard a new DashCaddy location:
+
+1. Open the Security Center on the central instance
+2. Hosts tab → Register Host → id=`nas1`, label="Synology NAS", type="dashcaddy"
+3. Save the displayed `api_key`
+4. On the remote host, run:
+   ```bash
+   curl -X POST https://central.sami/api/v1/security/events/ingest \
+     -H "Authorization: Bearer dca_xxx..." \
+     -H "Content-Type: application/json" \
+     -d '{
+       "source_type": "agent",
+       "actor": "1.2.3.4",
+       "target": "/volume1/web/login",
+       "action": "auth.login",
+       "outcome": "denied",
+       "severity": "warn",
+       "message": "Failed admin login"
+     }'
+   ```
+5. The remote host now appears in the Security Center's Hosts tab
+6. Events show up in the Events tab tagged with `source_host=nas1`
+
+A standalone DCA (DashCaddy Agent) binary that tails `/var/log/auth.log`, `/var/log/nginx/access.log`, etc. is **v2 work**.
+
+---
+
+## Performance & limits
+
+| Metric | v1 limit | Where it hurts at scale |
+|---|---|---|
+| Events in memory | 10,000 | Querying `?limit=10000` works; going beyond this hits only disk |
+| Events on disk | 100,000 (rotated) | Beyond this, oldest events get trimmed during `_maybeTrim()` |
+| Batch ingest size | 500 events/request | Adjustable in `routes/security.js` if needed |
+| SSE stream idle timeout | 30s heartbeat | Browser auto-reconnects |
+| Concurrent SSE clients | unbounded (each holds 1 HTTP connection) | For v2, add per-client cap |
+
+If you grow past 100k events on disk, **switch the store to SQLite**. The current JSONL design is intentionally simple for v1.
+
+---
+
+## What I deliberately did NOT build
+
+These are real features that you may want next, but I scoped them out to ship something working today:
+
+- ❌ **Alerting engine** — rules like "5+ failures from one IP in 60s → notify" — v2
+- ❌ **Active ban-from-UI** — `/api/v1/security/actions/ban` to push to shared_bans — v2
+- ❌ **GeoIP enrichment** — translate IPs to countries on ingest — v2
+- ❌ **DCA agent binary** — standalone Node.js process that tails arbitrary log files — v2
+- ❌ **Syslog UDP/TCP listener** — receive syslog directly on port 514 — v2
+- ❌ **Per-IP timeline view** — click an IP, see every event from them across all sources — v2
+- ❌ **Hot-archive / cold-archive tiering** — keep 30 days hot, compress older to monthly files — v2
+
+---
+
+## Testing performed (2026-07-13)
+
+| Test | Result |
+|---|---|
+| Event store append + query + stats | ✅ PASS — 5 events appended, queried by severity, stats aggregated correctly |
+| Persistence across "restart" | ✅ PASS — events survive reload from JSONL |
+| Host registry + auth | ✅ PASS — self-registered on first boot, Bearer-token auth round-trip works |
+| Caddy log worker (mock log) | ✅ PASS — 3 events emitted with correct severity (401→warn, 200→info) |
+| fail2ban log worker (mock log) | ✅ PASS — Ban/Unban events emitted |
+| shared_bans log worker (mock log) | ✅ PASS — "Applied N entries" event emitted |
+| All routes load without syntax error | ✅ PASS |
+| Routes factory returns Express Router | ✅ PASS |
+| audit-logger still loads after changes | ✅ PASS |
+
+---
+
+## Open questions / decisions to make
+
+1. **Where should the api_key for a remote host live in storage?** Currently it's returned once to the human operator, who must save it. A future "central-admin pulls from agent via reverse-channel" would be more secure but more complex.
+2. **Should the Caddy access log parser be on by default?** It requires Caddy to log JSON, which is a config change. The worker gracefully no-ops if the file doesn't exist.
+3. **Event retention policy.** Current default is 100k events on disk ≈ ~1 year at current volume, less under attack. Increase `SECURITY_EVENT_MAX_DISK` if needed.

+/**
+ * App startup require-graph smoke test (DC-020 regression guard)
+ *
+ * WHY THIS EXISTS:
+ *   The `refactor(desloppify)` commit deleted `license-keygen.js` thinking it was
+ *   stale dev-root noise. It is actually required by `src/managers/license-manager.js`
+ *   (`require('./license-keygen')`). The deletion put the production `dashcaddy-api`
+ *   container in a crash-restart loop (MODULE_NOT_FOUND from /app/src/app.js). A second,
+ *   masked bug had the same effect from the entry point: server.js used `require('./state-manager')`
+ *   which from /app/server.js resolves to /app/state-manager.js (does not exist) instead of
+ *   `./src/managers/state-manager`. The full Jest suite passed anyway because NO test ever
+ *   executed the real production require graph — every "app" test read src/app.js as a
+ *   string or rebuilt a minimal Express app with copied handlers, and server.js was never
+ *   loaded at all (requiring it starts the HTTP server + timers, which would leak workers).
+ *
+ *   This test closes that gap two ways:
+ *     1. Execute the real src/app.js require graph (catches deleted-module regressions).
+ *     2. Statically verify EVERY relative require in server.js resolves to a real file
+ *        (catches entry-point path bugs like the ./state-manager regression, without starting
+ *        the server). server.js cannot be require()'d directly because its top-level IIFE
+ *        binds port 3001 and starts interval-based feature modules.

+/**
+ * DC-111 regression pins — audit trail correctness for the SSO gate path.
+ *
+ * THREE live defects found 2026-08-23 by probing the production container
+ * (45,899 'unknown.get' entries in audit-log.json / security-events.jsonl
+ * spanning 2026-07-14 → 2026-08-23, plus failed actions dropped from the
+ * unified security event store):
+ *
+ * 1. audit-logger.middleware() computed action/resource from req.path
+ *    INSIDE the res.json override — i.e. AFTER the /api/v1 router had
+ *    rebased req.url to the router-relative path (/auth/gate/plex).
+ *    resolveAction fell through ACTION_MAP → 'unknown.get' for every
+ *    gate hit over HTTP. DC-028's unit tests passed because they call
+ *    resolveAction() directly with canonical paths and never exercise
+ *    the middleware over HTTP.
+ *
+ * 2. The DC-044 back-compat shim rewrote the ALREADY-canonical
+ *    /api/v1/auth/gate/<id> (and app-token) through '/api/v1' +
+ *    slice(4), producing /api/v1/v1/auth/gate/<id> → 401/404 for every
+ *    canonical-URI client — the exact drift case DC-044 meant to tolerate.
+ *
+ * 3. event-store VALID_OUTCOMES lacked 'failure' (the audit middleware's
+ *    vocabulary for data.success === false), so every failed API action's
+ *    security event was REJECTED and dropped from security-events.jsonl
+ *    ([AuditLogger] Security event emit failed: Invalid event: bad
+ *    outcome: failure — seen live in docker logs).
+ *
+ * These tests exercise a REAL Express app (not the module in isolation):
+ * the app-level DC-044 shim + audit middleware + a /api/v1 router that
+ * mounts the gate route the same way src/app.js does, so the router-rebase
+ * behavior that caused defect 1 is reproduced faithfully.

+ *     resource strings (URL paths like /invites/<email>/accept) and deep
+ *     details objects (req.body.email, DC-048 userEmail attribution).
+ *   - Masking happens at the single write-point log(), so middleware AND
+ *     direct route calls are both covered.
+ *   - Middleware's sensitive-key '***' redaction (password/token/…)
+ *     survives — masking runs on the already-sanitized object.
+ *   - The caller's `details` object is never mutated (maskEmails clones).
+ *
+ * Hermetic: AUDIT_LOG_FILE and SECURITY_EVENT_LOG_FILE are pointed at a
+ * tmp dir BEFORE the require — both modules resolve paths at load time.
+ *
+ * Read discipline: StateManager writes via fs.writeFile (truncate-then-
+ * write, NOT atomic) and middleware fires log() unawaited, so a fixed
+ * sleep can observe a 0-byte file mid-write. waitForEntries() polls for
+ * the expected entry COUNT — deterministic under lock retries.

+ * The checkout endpoint embeds the success_url (and cancel_url) into the
+ * Stripe Checkout Session. These URLs are what Stripe redirects the
+ * customer's browser to after payment. They MUST be derived only from
+ * trusted sources — otherwise a header-injection attacker could redirect
+ * customers to their own origin and capture the session_id, which is
+ * the bearer token for /api/v1/billing/lookup/:sessionId (and that
+ * endpoint serves the customer's license code on success).
+ *
+ * The origin is resolved in this priority order:
+ *   1. STRIPE_PUBLIC_ORIGIN env var (canonical deployment shape)
+ *   2. Request Host header, but ONLY when the host is in
+ *      STRIPE_ALLOWED_HOSTS (operator-declared allowlist)
+ *   3. undefined (Stripe falls back to its own defaults)

+ *  1. Configuration validation — missing STRIPE_SECRET_KEY fails loudly with 503.
+ *  2. productId validation — unknown productId returns 400 INVALID_PRODUCT_ID.
+ *  3. Product not configured — Stripe Price ID env var unset returns 503.
+ *  4. Happy path — creates a session with mode:payment + correct price ID + URLs.
+ *  5. Stripe SDK errors — surface as 502 to the customer, not 500.
+ *  6. Metadata contract — emits metadata.productId that the bridge can read back.
+ *  7. payment_intent_data — also carries productId metadata for downstream consumers.
+ *  8. Catalog drives everything — _resolveProduct reads the catalog, not env.

+ * `await`, this returned a Promise instead of an array, which then short-

+ * on-interval workflow ran successfully with 0 services checked, while
+ * the workflow engine still reported "Action health-check failed:
+ * servicesStateManager.getState is not a function" on the dashboard.
+ *
+ * Fix: call `await servicesStateManager.read()` with a .catch fallback to
+ * an empty array so a corrupt/missing state file doesn't break the

+/**
+ * DC-112 regression pins — caddy access-log worker event naming.
+ *
+ * Background (found 2026-08-23 while taking queue item (g)):
+ * the caddy tail worker named every event `http.<status>`, including
+ * forward_auth SSO gate hits — the same defect class as DC-111 defect 1
+ * (uniform action names make "who hit the gate?" unanswerable), in a
+ * different writer. Caddy gates call the API with the LEGACY pre-shim
+ * prefix (/api/auth/gate/<id>), dashboard JS with the canonical
+ * /api/v1/... prefix — both must map to the audit logger's ACTION_MAP
+ * vocabulary so both writers use the same names for the same request.
+ *
+ * Also pinned here:
+ *   - severity escalation for denied gate hits (warn, not notice)
+ *   - metadata fidelity: caddy logs headers as ARRAYS — the old
+ *     single-value read always produced user_agent: null
+ *   - metadata.host (which vhost served the request)
+ *   - the dead-path visibility warn: when the configured log path is
+ *     missing, the worker used to be fully silent — in the current DNS2
+ *     container there is no /var/log/caddy mount and no override, so ALL
+ *     caddy-source events were silently absent (store census: 45,912
+ *     events, 100% source_type 'api', zero 'caddy').
+ *
+ * The worker test exercises the REAL worker: a temp access log written
+ * like caddy writes it (JSON lines), a real tail with a short poll
+ * interval, and the real event store pointed at a temp jsonl. No mocks
+ * of the module under test.

+/**
+ * DC-113 regression pins — caddy security-event pipeline activation.
+ *
+ * Background (queue item h, 2026-08-23): the caddy tail worker was fully
+ * wired (DC-112 named the gate events) but 100% DEAD in production — no
+ * /var/log/caddy mount in the container, no CADDY_ACCESS_LOG env, and no
+ * global access log in the Caddyfile. Store census: 45,912 events, 100%
+ * source_type 'api', ZERO 'caddy'. DC-113 wires the pipeline:
+ *   - global Caddyfile logger `dashcaddy-access` (file /var/log/caddy/
+ *     access.log, roll 50MiB keep 5) + `log dashcaddy-access` in every
+ *     site block (via caddy-apply, host-side — NOT pinned here)
+ *   - start.sh: -v /var/log/caddy:/var/log/caddy:ro + CADDY_ACCESS_LOG env
+ *   - worker fixes pinned in THIS file:
+ *       1. real caddy JSON nests `host` inside `request` — the top-level
+ *          read (DC-112, fixture-shaped) always produced null on live lines
+ *       2. self-noise filter: the API's own probes (DashCaddy-Probe/1.0,
+ *          DashCaddy-HealthCheck/1.0) hit Caddy every 10-30s per service
+ *          and would bury real perimeter signal in the 100k-event store
+ *       3. recovered-log visibility (DC-112 judge polish fold): when the
+ *          access log appears after startup, one info line is logged
+ *
+ * All tests use the REAL worker: temp access log, real tail, real event
+ * store, hermetic sinks. No mocks of the module under test.

+/**
+ * Depth-2 route smoke-import tests
+ *
+ * Locks in the DC-005 path fix (commit c39c80b) so future refactors can't
+ * reintroduce broken require() paths in depth-2 route files.
+ *
+ * Background:
+ *   - The DC-005 src/ refactor moved route files into depth-2 subdirectories
+ *     (routes/auth/, routes/recipes/, routes/apps/, routes/arr/, routes/config/).
+ *   - The path-rewrite script left 67 broken require() paths across 21 files:
+ *     class A: '../../../src/...' (3 levels, goes above package root)
+ *     class B: '../src/utils/...' (1 level, resolves to nonexistent routes/src/)
+ *     class C: routes/apps/restore.js used 'utilities/responses' instead of 'utils/responses'
+ *   - The bug shipped because NO TEST imported any depth-2 route file. Only
+ *     depth-1 routes were tested.
+ *
+ * These tests do not exercise the routes' handler logic — that would require
+ * building full app contexts per route family. They only verify:
+ *   1. The module can be loaded without a MODULE_NOT_FOUND error.
+ *   2. It exports a callable factory function (module.exports = function(deps){...}).
+ *   3. The factory runs without throwing when given the minimum required deps.
+ *
+ * That alone catches ~80% of the DC-005 class: any require() with a wrong path
+ * blows up at module load time, before the factory is even called. Path bugs
+ * that only manifest at handler invocation time (e.g. require of a dep only
+ * used inside a handler body) won't be caught — but those are rare.

+/**
+ * DC-116 regression pins — security event store retention + query.total.
+ *
+ * Background (2026-08-23, one day after DC-113 activated the caddy source):
+ * live store had 46,494 events (16.5MB) growing ~2MB/day. Cold review of
+ * src/security/event-store.js found three defects:
+ *
+ *   1. query().total lied: the scan broke at offset+limit, so `total` was
+ *      capped at the page size (<=1000). LIVE user-facing impact — the
+ *      dashboard "N events (24h)" stat (status/js/security-center.js reads
+ *      data.total) and GET /hosts/:id/health events_24h showed 1000 when
+ *      the real 24h count was tens of thousands.
+ *   2. Trim trigger/curer mismatch: trigger was byte-based (>50MB) but the
+ *      curer was line-count-based (no-op unless >maxDisk=100k lines). If the
+ *      average line ever exceeded ~524B (50MB/100k — 0.5% of live lines were
+ *      already >524B, scanner bursts inflate metadata), trim fired on every
+ *      append and rewrote nothing — unbounded file + full-file re-read on
+ *      the write path.
+ *   3. Trim/append race: trim renamed over the file with appends in flight;
+ *      events appended after trim's readFile landed on the unlinked inode
+ *      and were silently lost.
+ *
+ * Tests use the REAL store with temp files. No mocks of the module under test.

+/**
+ * DC-096 regression tests: the `monitoring: { public: false }` config option
+ * actually gates the monitoring endpoints.
+ *
+ * WHY THIS EXISTS:
+ *   The middleware comment documented `monitoring: { public: false }` in
+ *   config.json as the way to require auth for /api/v1/monitoring/stats and
+ *   /api/v1/health-checks/status on internet-exposed deployments. But the
+ *   option was dead three ways:
+ *     1. applyConfigFields() never copied `monitoring` out of raw config —
+ *        siteConfig.monitoring stayed undefined forever.
+ *     2. `monitoring` was not in config-schema KNOWN_KEYS — saving it via
+ *        POST /api/v1/config produced "Unknown config key" warnings (save
+ *        still succeeded, so users saw a warning for a real feature).
+ *     3. MONITORING_PUBLIC was a const frozen at mount time AND re-required
+ *        the config/site singleton — POST /config changes never took effect
+ *        without a full process restart.
+ *
+ *   Net effect: an operator who set the documented hardening option on an
+ *   exposed box kept serving monitoring data unauthenticated, with only a
+ *   cosmetic warning. Classic "config option that never worked".
+ *
+ * These tests pin the fixed behavior:
+ *   - applyConfigFields copies monitoring through to siteConfig
+ *   - isPublicRoute honors the gate LIVE (no restart)
+ *   - env override still wins over config
+ *   - schema accepts `monitoring` and validates its shape
+ *   - typo keys setupCompleted/setupMode no longer silently allowlisted

+ * outer try/catch swallowed the resulting `TypeError [ERR_INVALID_ARG_TYPE]`

+ * falls back to platform-paths directly if `paths.dataDir` is missing.
+ *
+ * Tests use jest.isolateModules() for clean module-cache isolation.
+ * jest.doMock is intentionally avoided — it persists across tests in a

+/**
+ * Network IPs route + detector module tests — DC-031 regression guard
+ *
+ * WHY THIS EXISTS:
+ *   src/app.js:906 used to call `collectNetworkInterfaces(os)` after a DC-005
+ *   refactor dropped the `require('os')` line, leaving an `os is not defined`
+ *   ReferenceError on every hit to /api/v1/network/ips. The bug crashed the
+ *   Add Service modal (`status/js/core/service-create.js:57` calls this on open)
+ *   with a 500. ESLint also reports it as a hard error (`no-undef`), and no
+ *   test exercised the route handler — the 1067-test Jest suite passed anyway.
+ *
+ *   This test closes that gap two ways:
+ *     1. Unit-test the extracted detector module (`src/utilities/network-detector.js`):
+ *        covers the RFC 1918 LAN classifier, the Tailscale 100.64.0.0/10 classifier,
+ *        and the os-mocked `detectInterfaceIps()` returning `lan`, `tailscale`, and
+ *        the `all` array as expected.
+ *     2. Use `jest.isolateModules` to evaluate the route handler with a mocked
+ *        `os` and assert the handler returns 200 with the canonical envelope —
+ *        never the 500 that the missing-`require('os')` bug used to produce.
+ *
+ *   Both layers are necessary: the unit tests catch bugs in the classifier; the
+ *   route test catches regression of the wiring (e.g., a future refactor that
+ *   removes the require of `./utilities/network-detector` from src/app.js).
