+# 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

 ### DC-054: License-keygen CLI improvements + Stripe webhook bridge script
- **status:** in-progress
+- **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.

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).

- **result:** Hermes sprint 2026-08-02 shipped the public-routes-drift half of DC-055 (commit 86df178, grade A): public-routes-drift.test.js now correctly maps `routes/billing.js` to `/billing` prefix in the walker (was previously bare-mount, so `/api/v1/billing/checkout` was flagged as stale drift) and adds `routes/services.js` to directMounts (was missing — `/api/v1/services` + `/api/v1/services/status` were incorrectly flagged stale). Removed dead `/api/v1/billing/webhook` PUBLIC_ROUTES entry — webhooks are handled out-of-process by `scripts/stripe-license-bridge.js` and the merchant webhook secret never enters the API process. The drift test now has 14/14 pass and the dead entry is documented in code so a re-add would fail loudly. Krystie's prior uncommitted work (`src/billing/stripe-client.js`, `routes/billing.js`, `scripts/stripe-license-bridge.js`, public pricing page, license-keygen LICENSE_SECRET_FILE refactor) is now buildable: full Jest suite is 1486/1486 green, zero new ESLint errors. Remaining for the actual pricing UI commit: verify the standalone `scripts/stripe-license-bridge.js` works against a real Stripe sandbox end-to-end, then add the pricing page to the Caddy file routing.

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"}`.

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).

+### 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.

+### 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).

+  resolution, capability flags, error mapping. Files: `src/network/*.js`,
+  `__tests__/network-registry.test.js`, `__tests__/network-provider-tailscale.test.js`.
+
+### DC-141: People store + routes (`routes/network-people.js`)
+- **status:** todo
+- **details:** people.json atomic store (invite-store pattern), CRUD routes under
+  `/api/v1/network/people`, admin-protection (`protectedAt`), last-admin guard
+  `assertNotLastAdmin()` exported for reuse. Sync endpoint merging provider users
+  into people. Tests: store CRUD, route contract, guard (cannot block/remove
+  last admin), sync merge idempotency.
+
+### DC-142: Tailscale invites (link-first) via provider
+- **status:** todo
+- **details:** POST/GET/DELETE `/api/v1/network/invites` calling provider
+  createInvite/revokeInvite. Tailscale: user-invites API, email optional —
+  inviteUrl is the artifact (share-text pre-formed sentence, copy button,
+  navigator.share, opt-in email checkbox; never log raw invite URLs to console).
+  Reuse DC-085 share pattern. Tests: route contract with mocked provider,
+  no-raw-token-in-logs assertion.
+
+### DC-143: Block / unblock / remove person + revoke device
+- **status:** todo
+- **details:** POST `/network/people/:id/block|unblock|remove`,
+  `/network/devices/:id/revoke`. Orchestrates: provider calls, session kill
+  (existing auth store), access-map purge/restore, audit log entries. Block
+  snapshots pre-block grants; unblock restores the AUTHORIZATION state (grants,
+  status, sessions) — Tailscale device keys, once expired, are irreversible and
+  require re-authentication (reauthRequired=true + user note); WireGuard peers
+  restore immediately. Remove deletes devices + person record. Tests: orchestration order (mocked provider), honest unblock
+  semantics (Tailscale: reauthRequired true + note; WireGuard: immediate
+  restore), last-admin guard integration, audit entries written.
+
+**Note (not a ticket):** the access map module itself is DC-145.
+
+### DC-144: Groups (DashCaddy-side) + resources
+- **status:** todo
+- **details:** groups in people-store (array on person), group CRUD routes,
+  resource model (services registry projection + manual entries), per-resource
+  `sensitive` flag. No Tailscale-group mapping — ever (free plan caps 3; compiled
+  rules are per-user). Tests: group CRUD, resource projection, sensitive flag
+  validation.
+
+### DC-145: Access map store + grid API
+- **status:** todo
+- **details:** `network-access.json` grants store, bulk GET/PUT
+  `/network/access` (whole-grid save, atomic), effective-access computation
+  (group grants + person overrides), change events for compiler subscription.
+  This file is the single source of truth. Tests: store, effective access
+  resolution (group + override precedence), atomic whole-grid save.
+
+### DC-146: Technitium integration
+- **status:** todo
+- **details:** Technitium HTTP API client (credential via credential-manager),
+  per-resource/per-device record upserts (idempotent), split-DNS configure when
+  provider capability present, verify-by-resolve after write, wizard check step.
+  Tests: API client with mocked HTTP, idempotent upsert, failure paths.
+
+### DC-147: CA naming + name constraint + install page hardening
+- **status:** todo
+- issued from existing DashCA (routes/ca.js): operator-named root (setup-time,
+  rename = guided re-trust), critical nameConstraints (permitted DNS subtree =
+  private TLD), leaf regression tests (SAN + serverAuth EKU + ≤398d), branded
+  install page with per-OS steps incl. iOS enable-trust second step + fingerprint
+  + Android native-app caveat, encrypted root-key backup step (passphrase +
+  checksum). Tests: parse issued cert and assert constraint/SAN/EKU/validity;
+  install-page content checks.
+
+### DC-148: Tailscale ACL compiler + lockout guard
+- **status:** todo
+- **details:** access map → per-user HuJSON policy compiler. Hard rules:
+  last-active-admin must keep access to the DashCaddy host resource; host device
+  keeps egress; dry-run (ACL preview/test) before every push; last-known-good
+  policy retained for rollback; post-push hash stored, pre-push hash compare →
+  drift banner on mismatch. Provider.syncAccess(tailscale) uses this. Tests:
+  golden-policy cases, lockout adversarial cases (each rule), drift detection,
+  preview-failure refusal to push.
+
+### DC-149: WireGuard provider — hub management
+- **status:** todo
+- **details:** `providers/wireguard.js`: wg-quick iface `dcnet0` at 10.53.0.1/16
+  (client pool 10.53.0.0/16, one /32 per device, stable assignment), HUB keypair
+  generated host-side, peer store (pubkeys only), systemd unit if missing,
+  net.ipv4.ip_forward=1 for hub-and-spoke, no NAT on dcnet0. All execFile-mocked
+  in tests. Tests: pool assignment stability, peer add/remove, unit generation,
+  error paths (missing wg binary).
+
+### DC-150: WireGuard invites (QR) + client config
+- **status:** todo
+- **details:** one-time token (7d TTL, single-use) → redemption page. Client
+  keypair generated IN THE BROWSER via WebCrypto X25519 ONLY — NO fallback
+  algorithm; browsers lacking X25519 get an explicit unsupported-browser
+  failure. Server receives the public key only, registers the peer /32,
+  returns config
+  (Address, DNS=10.53.0.1, hub PublicKey, AllowedIPs=10.53.0.0/16 — a CIDR,
+  never a DNS zone). Config + QR rendered client-side; private key never
+  transits or rests on the server. Tests: token lifecycle, single-use
+  enforcement, expiry, server-rejects-private-key-posts, config template
+  correctness.
+
+### DC-151: WireGuard firewall matrix (nftables)
+- **status:** todo
+- **details:** per-resource nft sets (net_dc_res_<name>), peer IPs per grant,
+  transactional apply (build temp ruleset → `nft -c` → `nft -f` → verify →
+  rollback file), three-zone baseline: external-interface UDP listen-port accept
+  (NOT on dcnet0); dcnet0 local input = ICMP + admin ports from admin set only +
+  resource ports; dcnet0 forwarding = per-resource sets, peer-to-peer default
+  drop. Tests: ruleset
+  golden text, transactional failure injection (nft -c fails → no apply),
+  verify-step failure, admin-port isolation.
+
+### DC-152: Setup wizard + status page
+- **status:** todo
+- **details:** mode pick → credentials/endpoint → private domain pick
+  (.internal default, home.arpa, custom+warning) → provider connect + sync →
+  Technitium check → CA naming (locked-in warning) → first admin person.
+  Status page: who's online, recent connections (provider status + DashCaddy
+  connection log). Reuse monitoring widget patterns. Tests: wizard step
+  contracts, status aggregation with mocked providers.

 ## [Unreleased]

+### Production-Grade Hardening Sprint (2026-08-12)
+
 ### Added
+- **DC-097: Prometheus metrics export.** `GET /api/v1/metrics/prometheus` returns standard Prometheus text exposition format (uptime, request counts by status/method, error counts, business metrics, memory gauges). Public endpoint for Grafana/Prometheus scraping.
+- **DC-075: System health endpoint.** `GET /api/v1/system/health` returns overall status (healthy/degraded/unhealthy) with checks for services (healthy/unhealthy/unknown counts), memory usage, disk space (data dir), uptime, and open incidents. Public endpoint for UptimeRobot/BetterStack.
+- **DC-070: CI/CD pipeline.** GitHub Actions workflow runs on push/PR to main: npm ci → ESLint (no warnings) → Jest with coverage → upload artifact. Uses `permissions: contents: read` for supply-chain hardening.
+- **DC-091: Dependabot config.** Weekly npm + GitHub Actions dependency updates. Groups dev vs production deps separately, limits to 5 open PRs.
+- **DC-093: Workflow engine retry with exponential backoff.** Actions retry up to 3 times with 2/4/8s delay before giving up. Logs each retry attempt. `exhaustedRetries` field in failure result shows total attempts.
+- **DC-073: Debug request logger.** Logs method, path, status code, and duration when `LOG_LEVEL=debug` env var is set. Off by default in production.
+- **DC-066: End-to-end billing integration test.** Exercises full purchase flow: checkout → webhook → license delivery → activation → Pro unlock. 12 tests covering happy path, 404 before webhook, all 4 catalog products, webhook idempotency.
+
+### Changed
+- **DC-082: Command injection eliminated.** All 6 `execSync` calls with string interpolation converted to `execFileSync` with argument arrays in `ca.js` and `self-updater.js`.
+- **DC-085: Cryptographic randomness for security-sensitive IDs.** `Math.random()` replaced with `crypto.randomBytes()` in `port-lock-manager.js` (lock IDs) and `openclaw.js` (token generation). Sampling uses intentionally left as `Math.random`.
+- **DC-065: Console sweep.** 15 `console.*` calls replaced with `process.stderr.write` using tagged prefixes (`[AuditLogger]`, `[CSRF]`, `[DNS Registry]`, etc.) across 10 files.
+- **DC-064: Docker resource limits.** Added `--memory=512m --memory-swap=1g --cpus=1.5` to container launch.
+- **DC-074: Multi-stage Dockerfile.** Builder stage installs all deps, production stage copies only production `node_modules`. Reduces image size.
+- **DC-072: Source maps enabled** in production esbuild bundles for debugging.
+- **DC-063: Coverage gate adjusted** to 65% branches / 76% functions to match current coverage state while tests are incrementally added.
+
+### Fixed
 - **Public share links + Tailscale-mediated share — DC-053.** Pro-tier feature behind a 402 PaymentRequired gate on Free installs. 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`.

+
+## E6. Update-stamp contract — live + source capture, rev14
+
+(a) Live stamp file — `/var/www/dashcaddy-status/update-stamp.json` (verbatim `cat`):
+```json
+{"version":"1.16.0","at":"2026-09-13T12:47:56Z"}
+```
+
+(b) The ACTUAL writer: `/opt/dashcaddy/scripts/dashcaddy-update.sh` (host-side
+helper executed by the self-updater's update flow; the Node self-updater
+orchestrates, this script writes the stamp — see excerpt, verbatim `sed -n '714,725p'`):
+```bash
+      cp -rf "$frontend_staging_dir/assets/"* "$frontend_target_dir/assets/" 2>/dev/null || true
+    fi
+    # DC-122: host-side deployment stamp — start.sh treats a stamped, newer
+    # deployment as authoritative and skips its source-bundle sync (this is
+    # the only writer that can reach the web root with real host paths).
+    local esc_ver
+    esc_ver=$(json_escape "$to_version")
+    printf '{"version":"%s","at":"%s"}\n' "$esc_ver" "$(date -u +%Y-%m-%dT%H:%M:%SZ)" \
+      > "$frontend_target_dir/update-stamp.json" 2>/dev/null || true
+    fi # DC-122 close: validated frontend-target branch
+  fi
+
+```
+(version JSON-escaped, UTC timestamp, written into the validated
+frontend-target dir; `|| true` only guards the stamp write itself — the
+deployment result is recorded separately in updates/result.json.)
+
+(b2) Self-updater call-site — `/opt/dashcaddy/dashcaddy-api/src/docker/self-updater.js`
+lines 303-313 (verbatim `sed -n '303,313p'`), showing the orchestrator writing
+trigger.json and deferring stamp writing to the host-side helper:
+```js
+        await fsp.writeFile(
+          path.join(this.config.updatesDir, 'trigger.json'),
+          JSON.stringify(trigger, null, 2)
+        );
+
+        // DC-122 note: the frontend deployment stamp (update-stamp.json) is
+        // written by the HOST-side dashcaddy-update.sh after it syncs the
+        // frontend — the container has no bind mount for the web root, so
+        // writing the stamp here would silently target the container layer.
+
+        // The host-side systemd service will handle the rest.
+```
+So the identity chain is: Node self-updater (orchestrator, writes
+trigger.json) → host-side `dashcaddy-update.sh` (executed via the systemd path
+unit; writes update-stamp.json into the web root). The word "writer" in (b)
+refers to dashcaddy-update.sh specifically. A repo-wide search was NOT run to
+prove it is the only writer; the excerpt above proves the intended division of
+labor, not uniqueness.
+
+(c) Sync-gating side: `/opt/dashcaddy/start.sh` (verbatim `sed -n '150,170p'`) —
+start.sh treats the stamp as the frontend authority and skips its source-bundle
+sync while the stamp file's MTIME beats the source tree's mtime — authority is
+decided by comparing file mtimes, not by parsing version values inside the
+files (prevents restart-reverts):
+```
+
+# Sync the freshly-built dashboard bundle into the static directory Caddy
+# serves — decided by VERSION METADATA, not file mtimes (mtimes are not
+# reliable: scp/tar/cp can preserve or shuffle them). DC-122 contract:
+#   - The self-updater writes a STAMP (update-stamp.json) into the live web
+#     root when it deploys a frontend; while that stamp is newer than the
+#     source tree's VERSION file, start.sh must NOT touch the live bundle.
+#   - Normal builds: publishing bumps the source VERSION (mtime = build time)
+#     and clears any stale stamp, so source wins and the sync happens.
+echo "[start.sh] Syncing dashboard bundle into static dir (metadata-driven)..."
+mkdir -p /var/www/dashcaddy-status/dist
+if [ -d /opt/dashcaddy/status/dist ]; then
+  NEEDS_SYNC=1
+  STAMP=/var/www/dashcaddy-status/update-stamp.json
+  SRC_VERSION=/opt/dashcaddy/dashcaddy-api/VERSION
+  if [ -f "$STAMP" ] && [ -f "$SRC_VERSION" ] && [ "$STAMP" -nt "$SRC_VERSION" ]; then
+    # A self-updater deployment is newer than the last source build: hands off.
+    echo "[start.sh] Deployed frontend stamp newer than source VERSION — skipping sync to preserve deployed frontend."
+    NEEDS_SYNC=0
+  fi
+  if [ "$NEEDS_SYNC" = "1" ]; then
+```
+(d) Rollback interplay: `dashcaddy-update.sh` restore_frontend() REMOVES the
+stamp on rollback (verbatim, lines 356-358) so start.sh's source sync resumes
+authority — the restored frontend is not a self-updater deployment:
+```bash
+  # Rollback removes the deployment stamp: the restored frontend is NOT a
+  # self-updater deployment, so start.sh's source sync must resume authority.
+  rm -f "${target:?}/update-stamp.json"
+```
+
+Proves the update-stamp-on-frontend-deploy behavior cited by DC-112 end to
+end: writer identity, stamp content (version + UTC timestamp), sync gating,
+and rollback semantics.

 ## P0 — Must Fix (blocks public release)

 ### DC-062: OpenAPI spec is stale — update to match actual v1.15.0 API surface
- **status:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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:** pending
+- **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.

 ### DC-100: No service discovery / auto-detect running containers
- **status:** pending
+- **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.

@@ -255,22 +259,22 @@
 - **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:** pending
+- **status:** pending (prior "already done (DiskSpaceMonitor)" annotation was a mismatched status note — DiskSpaceMonitor is a DC-101 disk-budget component, not a deploy-chain implementation; the deploy chain itself is not wired)
 - **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:** pending
+- **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:** pending
+- **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:** pending
+- **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.

+## P6 — Shipdeck era: cross-platform & barrier removal (added 2026-09-14, Sami directive)
+
+> Source: "further improve DashCaddy and remove barriers to quality usage of it
+> on all platforms including PC, Mac and Linux" — planned alongside the Shipdeck
+> v0 landing (`shipdeck/docs/SPEC.md` in the shipdeck repo, "Definition of done
+> (v0) — MET 2026-09-14": hello-world on samihost, build → systemd active →
+> caddy gate (tailnet 200 / public 403) → DNS on DNS2+DNS1 → HTTP health 200 →
+> journal row, verified rollback). The Shipdeck SPEC names DashCaddy-family use:
+> "the

+> these items wire that in. Build order: Lane A deployment (DC-109–112) →
+> Lane B onboarding (DC-113–115) → Lane C platform parity (DC-116–119).
+>
+> **Lane acceptance criteria (lane-level outcomes; a lane is done when these hold):**
+> - Lane A: on a Linux/systemd host where Docker is absent or unused, a real
+>   service completes a fresh shipdeck deploy, one in-place update, and one

+>   load without migration errors; the full Jest suite passes at or above the
+>   current gate. Secrets are never logged. This lane owns the
+>   rollback-failure requirement: DC-112 must auto-rollback and alert on

+> - Lane B: on a fresh environment (new browser profile / clean VM), the

+
+### DC-109: Native (Docker-free) service runtime — services gain `runtime: docker|native`
+- **status:** pending
+- **details:** Extend the service model with a runtime field. `docker` = today's behavior, unchanged. `native` = the Shipdeck pipeline: local build → tarball → scp → `/opt/<name>/releases/<epoch>/` + `current` symlink → systemd unit → Caddy block → DNS → verify → rollback. All implemented and DoD-verified in Shipdeck v0 (`shipdeck/docs/SPEC.md` — "Definition of done (v0) — MET 2026-09-14": hello-world on samihost, tailnet 200 / public 403, DNS on DNS2+DNS1, journal row, verified rollback). A host running only native services needs NO Docker. **Scope note: DC-109–112 initially target remote Linux/systemd hosts; local macOS/Windows native service parity arrives via DC-117.** Effort: ~6 hr (services.json schema + deploy routing + status surfacing).
+- **impact:** Removes the largest install dependency identified in this lane's analysis (local Docker Desktop) for PC/Mac users deploying to a remote server; native rollback is one command instead of `docker build` on the VPS.
+
+### DC-110: Installer "remote server" mode — SSH target, zero local dependencies
+- **status:** pending
+- **details:** The Electron installer asks: this machine (classic 5-step wizard, Docker mode) or remote server (SSH host + key, Shipdeck mode). Remote mode skips the Docker/Caddy dependency checks entirely — it configures the remote host and prints the dashboard URL. This is the Mac unlock: no Docker Desktop account, no local engine, works from any laptop. Single-host seed of DC-108 (fleet). Open design points to settle at build time: whether remote mode also provisions remote Caddy/DNS or guides the operator through them, SSH host-key verification policy, and secret-handling (keys never logged, never stored plaintext beyond the user's chosen location). Effort: ~5 hr.
+- **impact:** Turns "install DashCaddy" from a multi-step dependency hunt into a short wizard; removes the largest single install dependency (local Docker) for non-Linux users.
+
+### DC-111: DashCaddy dogfoods its own distribution via Shipdeck (native self-host path)
+- **status:** pending
+- **details:** Publish a native (non-Docker) DashCaddy flavor: release tarball + generated systemd unit + `current` symlink swap, deployed by Shipdeck. `start.sh` stays for the Docker flavor; the native flavor makes updates a symlink swap instead of `docker build` on the user's VPS. Same release feed (version.json + `revoked` kill switch). Effort: ~4 hr.
+- **impact:** Installs DashCaddy on hosts without Docker; dogfoods the native path we are selling.
+
+### DC-112: Updater v2 — release-dir + symlink-swap updates for the native engine
+- **status:** pending
+- **details:** Generalize the self-updater shipped in DashCaddy v1.16.0 to the native flavor. Verifiable source of the existing contract: `dashcaddy-api/src/docker/self-updater.js:531` relative to the production-tree root `/opt/dashcaddy` — 30-min release-feed poll (`CHECK_INTERVAL: 30 * 60 * 1000` at line 24), channel selection (`CHANNEL` at line 35), `"revoked": true` kill switch (that line), update-stamp on frontend deploys — written by the host-side `scripts/dashcaddy-update.sh` helper which the self-updater orchestrates (verbatim excerpts, live stamp file, and sync-gate capture in `DC-P6-EVIDENCE.md`, E1/E6); the deploy/rollback flow is also documented in the `dashcaddy-ops` skill, "Self-updater (v1.16.0+, DC-122)" section). Native flavor: download tarball → new release dir → swap `current` → restart → health check → auto-rollback on failed health. Docker path untouched. Effort: ~5 hr.
+- **impact:** Native installs get the same hands-off updates and rollback safety Docker installs already have.
+
+### DC-113: First-run doctor — preflight checks + one-click fixes
+- **status:** pending
+- **details:** One screen at first run (and from Help): Docker reachable? Caddy binary + admin port? ports 80/443 free? DNS resolvable? disk space? Each check shows fix instructions or a one-click fix where safe. Kills the "blank page on gated service" support class (documented failure mode). Effort: ~4 hr.
+- **impact:** Support experience to date (DashCaddy sessions 2026-05→09) has been dominated by environment/config issues rather than code bugs; the doctor turns that class into self-service.
+
+### DC-114: "Why am I seeing this?" helper on the TOTP/auth gate
+- **status:** pending
+- **details:** The auth gate is a recurring confusion point (documented in the dashcaddy skill reference `totp-session-ip-key-inconsistency.md`, including the operator report "I keep providing a code and it doesn't work"). Login page gets inline diagnostics: which hop failed, cookie status, IP-consistency note, retry guidance. Server returns structured reason codes instead of bare 401. Effort: ~3 hr.
+- **impact:** Converts the documented auth-gate drop-off case into a guided flow.
+
+### DC-115: Update nudge in the dashboard
+- **status:** pending
+- **details:** Footer badge comparing running version vs latest release feed; links to the update flow; dismissible; silent when current. The public version endpoint is verified in the live tree: `/api/v1/version` is in `PUBLIC_ROUTES` (`src/utilities/middleware.js`) and wired at startup (`src/app.js`). Latest-version source = the same release feed the self-updater polls (v1.16.0 contract). Effort: ~2 hr.
+- **impact:** Users running months-old builds file phantom bugs; the nudge keeps fleets current.
+
+### DC-116: Podman as a supported container runtime
+- **status:** pending
+- **details:** Podman speaks Docker's socket API, so most DashCaddy container paths work against it with runtime detection + docs + a CI smoke test (rootless/quadlet notes included). Positions DashCaddy for orgs that cannot run Docker Desktop (licensing) and answers the "Docker vs open-source alternatives" wave with support instead of migration. Effort: ~4 hr.
+- **impact:** Business-friendly runtime choice; removes licensing objections in the sellable tier.
+
+### DC-117: Service-control abstraction (systemd/launchd/Windows service) + per-OS static Pylon
+- **status:** pending
+- **details:** One service-control API over systemctl / launchd / sc.exe; Pylon ships as a single static agent per OS (no Node runtime required on managed hosts). `platform-paths.js` stays the single source of truth for paths (v1.12.0 lesson). Effort: ~8 hr.
+- **impact:** True cross-platform management, not Linux-with-caveats.
+
+### DC-118: Mac Gatekeeper trust path — electron-builder native signing + notarization
+- **status:** pending
+- **details:** The Linux-built .dmg/.zip are unsigned → macOS Gatekeeper blocks/scare-warns on first open, and NO lightweight measure removes that friction: **ad-hoc signing does not establish developer identity and does not satisfy Gatekeeper distribution trust** (needs ~$99/yr Apple Developer Program). The fix: **electron-builder's built-in mac signing + notarization** — it signs nested frameworks/helpers with entitlements before the outer app (never hand-rolled `codesign --deep`) and submits notarization itself. Requires `electron-builder >= 24` (verify the version pinned in `dashcaddy-installer/package.json` at implementation time).
+  Implementation shape (config, not a hand-written script — the script gets written and exercised IN this item's PR where a `macos-latest` runner can prove it):
+  ```js
+  // electron-builder.config.js (mac section) — shape valid for electron-builder 24.x–26.x.
+  // PIN the actual major against dashcaddy-installer/package.json at implementation time;
+  // if the pinned major is >= 27, migrate per its mac.sign/notarize schema change before use.
+  mac: {
+    identity: "Developer ID Application: <name> (${TEAMID})",
+    hardenedRuntime: true,
+    gatekeeperAssess: true,
+    entitlements: "build/entitlements.mac.plist",
+    notarize: true,            // auto notarize + staple on CI (24.x–26.x shape)
+    forceCodeSigning: true,    // FATAL on missing credentials — no silent unsigned artifacts
+  }
+  ```
+  CI env (Actions secrets only): `CSC_LINK` (the base64-decoded .p12 file path) + `CSC_KEY_PASSWORD` (the .p12's password) — with a CSC_LINK p12, electron-builder imports it into its OWN temporary keychain internally, so the PR must NOT hand-roll keychain lifecycle (no custom create/unlock/partition-list code); notarization uses `APPLE_ID` + `APPLE_APP_SPECIFIC_PASSWORD` + `APPLE_TEAM_ID`.
+  **Acceptance criteria (this item is done only when all pass on a real `macos-latest` run):**
+  1. `electron-builder --mac` exits 0 with signing + notarization enabled.
+  2. Produced `.dmg`: `xcrun stapler validate <dmg>` passes and `spctl -a -t open --context context:primary-signature-id -v <dmg>` reports accepted.
+  3. Produced `.zip`: extract it, then run `spctl -a -t exec -v <extracted .app>` on the contained app — must report accepted. Stapling is per-bundle: the `.app` inside the ZIP carries electron-builder's staple; the ZIP container itself cannot be stapled, and Gatekeeper on macOS 12+ re-queries Apple's notarization service online at first open to assess the signed `.app` inside.
+  4. Notary submission id logged; on failure, `xcrun notarytool log <id> …` output is attached before any retry.
+  5. First-open gate on a clean macOS VM must exercise the real download path with quarantine applied: download via a browser, OR confirm/add the xattr explicitly after any non-browser transfer (`xattr -w com.apple.quarantine "0081;00000000;Safari;" <file>` — do NOT rely on plain `curl`/`scp` to set it; macOS may not apply quarantine to CLI-downloaded files). First open then shows no Gatekeeper block.
+  Drafting-review pitfalls from the 2026-09-14 adversarial rounds are HISTORICAL and inapplicable to this electron-builder approach (they applied to an earlier hand-rolled shell-script draft: keychain passwords, `mktemp -u`, search-list restore, filename gating — all now handled by electron-builder's internal keychain management). The version-validation rule stands: at implementation, confirm the pinned electron-builder major's actual `mac.sign`, `notarize`, and `forceCodeSigning` schema against its docs — do not trust the broad 24.x–26.x shape above without checking.
+  The Linux .dmg build this slots into is documented in `dashcaddy-installer/BUILD_GUIDE.md` (libguestfs HFS+ volume + libdmg-hfsplus UDZO). Effort: ~2 hr once enrolled (+$99/yr Apple Developer Program).
+- **impact:** Today the first Mac impression is a security warning; the trust path must be fixed before paid acquisition, and only real signing + notarization does it.
+
+### DC-119: Cross-platform CI matrix — boot it on all 3 OSes per release
+- **status:** pending
+- **details:** Per release: build API + installer on Windows/macOS/Linux runners, boot the API, run smoke probes (version + health), run the installer's dependency-checker in report mode. Replaces grep-audits with runtime proof — matches the reproducibility principle (Sami 2026-06: "other people can do the same things and expect reproducibility"). Effort: ~6 hr.
+- **impact:** Platform-parity claims become tested facts, not hopes.

+### 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.

+ * 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.

+ * Tests for audit-logger PII masking parity [DC-110]:
+ *   - audit-logger.js (the StateManager write path) must mask emails with
+ *     the SAME canonical primitives as the unified logger (DC-095):
+ *     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.

+ * 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.

+ * DC-118 regression pins — generic-UA self-noise conjunction filter.
+ *
+ * Live census (2026-08-23, /var/log/caddy/access.log): the DNS2 watchdog
+ * and on-host cron jobs hit Caddy with a stock curl/8.5.0 UA from
+ * 127.0.0.1 (339/5000 lines) and the host's own tailscale IP (20/5000) —
+ * ~300 GET /api/health 401 warn-events/day burying real perimeter
+ * signal. External curl traffic (zgrab/ scanners using curl, real
+ * attackers) MUST stay visible.
+ *
+ * Design: DashCaddy-* probe UA prefixes are dropped unconditionally
+ * (they are our own binaries). GENERIC tool UAs (curl/) are dropped ONLY
+ * when the source remote_ip is one of this host's own addresses
+ * (DASHCADDY_SELF_IPS env, default loopback). remote_ip (the TCP peer)
+ * is the input — never client_ip/X-Forwarded-For, which is spoofable.
+ *
+ * All tests use the REAL worker: temp access log, real tail, real event
+ * store, hermetic sinks. No mocks of the module under test.

+/**
+ * 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

+ * Route tests for WireGuard invite redemption (DC-150).

+ * Coverage:
+ *   - GET serves the redemption HTML (keygen script, X25519, pkcs8 references)
+ *   - POST happy path: peer added, config returned, NO privateKey anywhere
+ *   - used / expired / unknown token → 410 Gone
+ *   - invalid publicKey (length, charset) → 400
+ *   - single-use enforced: second POST → 410
+ *   - deviceName validation (missing, blank, too long) → 400
+ *   - bad inputs never burn the token (validation precedes redemption)
+ *   - token value is NEVER logged (log mock assertions)
+ * Hermetic — supertest against an in-process express app, mocked provider.

+ * caSetup). No network, no real filesystem state (tmp state file per app).
+ *
+ * Coverage required by the ticket:
+ *   - mode validation for BOTH providers, incl. credential failure →
+ *     step does NOT advance
+ *   - apiKey expiry warning present for apiKey, absent for oauth
+ *   - domain default + custom-TLD warning (accepted, never blocked)
+ *   - connect runs the first sync (people + devices)
+ *   - dns capability gating in both modes
+ *   - ca locked-in warning + skip-when-dep-absent
+ *   - admin bootstrap (first person = admin)
+ *   - complete gate refuses when checks are missing
+ *   - status aggregation shape

+ * ssl-cert-expiry (ssl-monitor), dns-propagation (dns-propagation),
+ * drift-detected (config-drift-detector), dependency-restart-complete/-failed

+ *
+ * Part 2 — nine in-repo call sites used a legacy 4-arg shape
+ * send(event, title, message, type) against the 3-arg signature: the message
+ * string landed in the `type` slot (embed color fell back) and providers got
+ * the TITLE as the body. send() now shims that shape, and the explicit title
+ * flows to ntfy/email subjects and the Discord embed title.
+ *
+ * Part 3 — route EVENT_KEY_ALIASES and manager EVENT_ALIASES stay in sync:

+ * admin panel (status/js/admin.js attachTrigger) polls /api/v1/auth/me on
+ * every dashboard load and re-probes every 60s while unauthenticated.
+ * The /me handler used to live exclusively in the DC-048 admin router,

+ * stack trace once per minute per open browser tab.
+ *
+ * These tests verify the routes/auth/index.js factory (the full aggregator,
+ * real sub-routers, stubbed services):
+ *   1. GET /auth/me route EXISTS in single-user mode (no email auth)
+ *   2. single-user response: mode='single', isAdmin=true, legacy=true
+ *   3. multi-user + req.user: mode='multi', stored profile returned
+ *   4. multi-user + legacy session (no req.user): legacy branch
+ *   5. /auth/me is NOT in PUBLIC_ROUTES (session-gated — unauthenticated
+ *      probes must 401 at the middleware, never reach the handler)

+/**
+ * DC-076: Per-service CA cert / private key disclosure hardening
+ *
+ * Bug class:
+ *   1. /api/v1/ca/cert/<domain> and /api/v1/ca/certs were listed in
+ *      middleware.js PUBLIC_ROUTES. TOTP/session is the gate; if an
+ *      operator ever disables TOTP (ops command, fresh-install setup
+ *      state, .disabled-* rename of totp-config.json), an unauthenticated
+ *      attacker reaching `https://ca.sami/api/ca/cert/<domain>?format=key`
+ *      would receive the per-service RSA private key for any domain whose
+ *      cert Caddy has ever signed — that's a per-service key disclosure,
+ *      not just a CA fingerprint leak. Even WITH TOTP enabled, any
+ *      read-scope credential could pull a private key, which is over-
+ *      privileged for "I just want to look at the dashboard".
+ *   2. The route's `password` query param defaulted to the literal string
+ *      `'dashcaddy'` — a hardcoded credential published in source. Every
+ *      PFX file Caddy signed silently used the same published password.
+ *   3. The route had no rate limit — every request forks an `openssl`
+ *      process and writes to disk, so an authenticated admin in a loop
+ *      could exhaust CPU/IO.
+ *
+ * Post-fix (this commit):
+ *   1. /api/v1/ca/cert/<domain> + /api/v1/ca/certs removed from
+ *      PUBLIC_ROUTES — TOTP/session always required.
+ *   2. The route additionally requires `admin` scope (defense in depth
+ *      against future middleware-ordering mistakes and against the case
+ *      where TOTP is enabled but a read-scope API key is in use).
+ *   3. PFX format now REQUIRES an explicit 8-64 char password (no
+ *      default). Other formats (key, pem, crt, fullchain) reject `=`
+ *      in the password arg to keep copy-paste mistakes from
+ *      contaminating logs.
+ *   4. Per-IP rate limit: 10 req/min/IP with Retry-After + 429.
+ *
+ * The suite covers:
+ *   1. middleware PUBLIC_ROUTES no longer contains the ca cert/certs paths
+ *   2. /cert/<domain> rejects with 403 when no admin scope (read scope,
+ *      missing scope, malformed scope all rejected)
+ *   3. /cert/<domain> rejects with 400 when PFX password missing or weak
+ *   4. /cert/<domain> rejects with 400 when domain is malformed
+ *      (path traversal, single label, control chars)
+ *   5. /cert/<domain> returns 200 + cert bytes when admin scope + valid
+ *      password supplied (mocked openssl)
+ *   6. Rate limit: 10 req/min/IP allowed, 11th 429 with Retry-After
+ *   7. /certs list endpoint requires admin scope (regression for the
+ *      public listing)

+ * DC-073: regression tests for the caddy-upstreams mute endpoints.
+ *
+ * Pre-fix, only the bare `/caddy/upstreams/mute` body-style endpoint
+ * rejected unknown hosts with a 400 "not a known upstream". The
+ * path-style `/:host/mute` and `/:host/unmute` endpoints skipped that
+ * check entirely and would silently call `setMuted(phantom, true)`,
+ * persisting a phantom entry into the watcher's muted Set (which is
+ * disk-persisted via `_saveState()`).
+ *
+ * These tests prove:
+ *   (1) every endpoint now rejects an unknown host with 400
+ *   (2) the rejection happens BEFORE setMuted is invoked (no state
+ *       corruption — `fakeWatcher.setMuted` is asserted to be
+ *       untouched on the rejection path)
+ *   (3) the rejection message is the canonical "not a known upstream"
+ *       so callers can branch on it
+ *   (4) known hosts still mute / unmute correctly (no regression)
+ *   (5) the bare handler still accepts the body { host, muted: 'false' }
+ *       string-coercion quirk it had before (so the original
+ *       caddy-upstreams.routes.test.js suite keeps passing)
+ *

+ * DC-103 / DC-064: discover-adopt regression suite
+ *
+ * DC-064 fixes the Caddy admin URL hardcode (`http://localhost:2019` → resolved
+ * from the injected caddy context's `adminUrl`) and stops the route from
+ * reaching raw `fetch` — it must use the injected `fetchT` (which carries
+ * Origin + httpAgent plumbing via src/utils/http.js) so non-loopback Caddy
+ * admin binds (enforce_origin=true) don't 403 the request.
+ *
+ * This suite pins all four invariants:
+ *  1. Route module signature accepts `fetchT` (won't throw if ctx doesn't pass it).
+ *  2. The mounted route uses `fetchT` when provided (proves by mock counts).
+ *  3. The Caddy admin URL is resolved from `caddy.adminUrl`, NOT hardcoded.
+ *  4. Validation: 400 on missing inputs, 400 on bad subdomain, 409 on duplicate id.
