BACKLOG: document DC-033 (done) + add DC-034..041 from v1.14.8/0.0.0 incident

Captures the work done in this session (DC-033) and surfaces 9 follow-up
items that came out of the cross-check investigation:

P1: DC-034 (regenerate release tarball as 1.14.9), DC-035 (regression test
for getLocalVersion), DC-036 (delete dead root self-updater.js), DC-037
(move symlink creation into install script so fresh hosts don't repeat
the v1.14.4 failure mode).

P2: DC-038 (backup trigger.json/result.json), DC-039 (audit for other
__dirname antipatterns), DC-040 (audit whether post-deploy-patches.sh is
still needed), DC-041 (integration test for the auto-update pipeline).

Each ticket cites the specific files, commit SHAs, and evidence from
this session so future agents can pick up where this left off.

+
+### 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.
+
+---
+
+## P1 — Code Quality
+
+### 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:** in-progress
+- **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.
+
+## P2 — Polish & DX
+
+### 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:** todo
+- **owner:** unclaimed
+- **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.
+- **impact:** Every host auto-updating gets the 0.0.0 fix for free without needing a manual symlink or git pull.
+
+### DC-035: Add regression test for getLocalVersion() — prevent DC-033 class from regressing
+- **status:** todo
+- **owner:** unclaimed
+- **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}$/`. Optionally: parameterize to also exercise `require('./self-updater')` from `/app` cwd to verify the legacy root-copy contract still works. Effort: ~20 min. Pattern: matches DC-017's depth-2-routes-smoke.test.js (loads every module via the real path).
+- **impact:** Catches the exact class of bug DC-033 fixed, plus any future refactor that re-introduces the __dirname antipattern.
+
+### DC-036: Delete dead `dashcaddy-api/self-updater.js` (root copy) — 0 runtime callers
+- **status:** todo
+- **owner:** unclaimed
+- **details:** After DC-005 refactor (commit 283121e), there are TWO SelfUpdater implementations on disk: `/opt/dashcaddy/dashcaddy-api/self-updater.js` (md5 `79d566cc...`) and `/opt/dashcaddy/dashcaddy-api/src/docker/self-updater.js` (md5 `b3b61557...`). Both have drifted. **Zero runtime callers of the root copy** — verified by `grep -rn "require.*self-updater" dashcaddy-api/ --include="*.js"` which shows only `./src/docker/self-updater` (in server.js + src/app.js). The root copy is dead code from a prior refactor and a footgun for future contributors who edit the wrong file. Subagent flagged this independently. Fix: `git rm dashcaddy-api/self-updater.js` + verify `npx jest --passWithNoTests` still passes. Risk: very low. If a test does import it, the test itself is wrong and should be deleted or pointed at `./src/docker/self-updater`.
+- **impact:** Removes the wrong-file-edit footgun. Makes DC-035's test cleaner (only one SelfUpdater implementation to test).
+
+### DC-037: Move `/etc/dashcaddy/sites/dashcaddy-api` symlink creation into the install script
+- **status:** todo
+- **owner:** unclaimed
+- **details:** DNS2 has the symlink manually created during this session (2026-07-05), but every other fresh DashCaddy install will hit the same `cp: cannot create directory '/etc/dashcaddy/sites/dashcaddy-api/routes': No such file or directory` failure when the first auto-update lands, because `dashcaddy-update.sh` defaults `apiSourceDir` to `${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.

+### DC-038: Backup trigger.json + result.json in dashcaddy-update.sh — enable one-command rollback
+- **status:** todo
+- **owner:** unclaimed
+- **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.
+
+### DC-039: Audit repo for other `__dirname + sibling-file` patterns — DC-033 class of bug
+- **status:** todo
+- **owner:** unclaimed
+- **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.
+
+### DC-040: Investigate whether dashcaddy-post-deploy-patches.sh is still needed at all
+- **status:** todo
+- **owner:** unclaimed
+- **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.
+
+### DC-041: Add integration test for the auto-update pipeline (trigger.json → bash → docker rebuild → health check → result.json)
+- **status:** todo
+- **owner:** unclaimed
+- **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.
+- **impact:** Closes the biggest untested surface in DashCaddy. Would have caught the v1.14.4 packaging bug immediately on the next release.

+
+## 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).
+
+## Coordination Rules
+
+1. **Always `git pull` before starting work.**
+2. **Claim a task by editing BACKLOG.md:** set `status: in-progress` and `owner: hermes` or `owner: krystie`.
+3. **Commit BACKLOG.md claim first**, then start coding.
+4. **Run tests before pushing:** `cd dashcaddy-api && npx jest --passWithNoTests`
+5. **Push to `main`** — use `http://sami7777:<token>@100.98.123.59:3000/sami7777/dashcaddy.git`
+6. **Update BACKLOG.md** when done: set `status: done`, add brief result under the task.
+7. **Never work on a task another bot has claimed** (status: in-progress).
+8. **Quality bar:** this is a public-release product. No hacks, no env-var workarounds, no per-machine patches. Fixes go in the shared codebase.
+9. **VERSION bump:** when a batch of tasks is done, bump patch version in package.json + VERSION file, update CHANGELOG, tag.

+# 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' \
+    -C /opt/dashcaddy -cf - . | tar -C /tmp/verify/repo -xf -
+
+# 2. Replicate the assembly from build-release.sh against the snapshot
+cd /tmp/verify/repo
+mkdir -p /tmp/verify/dashcaddy/dashcaddy-api/routes /tmp/verify/dashcaddy/status /tmp/verify/dashcaddy/scripts
+STG=/tmp/verify/dashcaddy
+cp -f dashcaddy-api/*.js "$STG/dashcaddy-api/" 2>/dev/null || true
+cp -rf dashcaddy-api/routes "$STG/dashcaddy-api/"
+cp -f dashcaddy-api/package.json "$STG/dashcaddy-api/"
+cp -f dashcaddy-api/package-lock.json "$STG/dashcaddy-api/" 2>/dev/null || true
+cp -f dashcaddy-api/Dockerfile "$STG/dashcaddy-api/"
+cp -f dashcaddy-api/openapi.yaml "$STG/dashcaddy-api/" 2>/dev/null || true
+[ -d dashcaddy-api/src ] && cp -rf dashcaddy-api/src "$STG/dashcaddy-api/"
+[ -d dashcaddy-api/assets ] && cp -rf dashcaddy-api/assets "$STG/dashcaddy-api/"
+[ -d dashcaddy-api/scripts ] && cp -rf dashcaddy-api/scripts "$STG/dashcaddy-api/"
+# ... status/ + scripts/ as in build-release.sh ...
+
+# 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.

CHANGELOG.md

@@ -7,6 +7,82 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [Unreleased]
 
+### 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.
+
+### 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.
+
+### 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.
+
+## [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.

-### 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`)

+## 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)

+
+/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.

+## 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.
+

+/**
+ * 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.

+ * 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.

+/**
+ * Public-routes allowlist drift tests
+ *
+ * Three allowlists in the DashCaddy codebase grant "no auth" or "no CSRF"
+ * access to specific paths. They MUST stay in sync — if a path is in
+ * PUBLIC_ROUTES but NOT in csrf excludedPaths (for a POST), the request gets
+ * a 403. If a path is in csrf excludedPaths but NOT in PUBLIC_ROUTES, it gets
+ * a 401. Both bugs are silent and ship-blocking for fresh users.
+ *
+ * Three lists:
+ *   1. PUBLIC_ROUTES — in src/utilities/middleware.js, used by auth middleware
+ *   2. excludedPaths — in src/security/csrf-protection.js, used by CSRF middleware
+ *   3. Request-logging skip list — in src/utilities/middleware.js, used by request logger
+ *   4. Tailscale auth bypass — in src/utilities/middleware.js, used by Tailscale gate
+ *
+ * Tests assert:
+ *   A. No stale entries in any allowlist (path not in source-of-truth route mounts)
+ *   B. The CSRF excludedPaths list is a subset of PUBLIC_ROUTES (any CSRF-exempt
+ *      path must be publicly accessible)
+ *   C. Probe paths appear in all three lists (liveness/readiness probes must
+ *      bypass auth, CSRF, AND request logging)
+ *
+ * Source of truth for which paths are mounted:
+ *   - src/app.js (inline apiRouter.get/post routes)
+ *   - routes/[subdir]/[file].js (router.get/post/put/delete calls)
+ *
+ * The sync regex is conservative — matches quoted paths in mounted-route calls.
+ * False positives (e.g. comments containing route-like strings) are filtered
+ * by requiring the path to also be a real file in the routes/ tree OR appear
+ * inside an `apiRouter.` / `app.` call expression.
