fix(ca): gate per-service cert/key download behind TOTP+admin scope; require explicit PFX password; add rate limit (DC-076) [glm-grade=A]

Pre-fix, an authenticated dashboard operator could call:
  POST /api/v1/site         {domain:"evil.example.com", upstream:"10.0.0.1:80"}
  POST /api/v1/site/external {subdomain:"x", externalUrl:"http://192.168.1.5"}
and end up with a Caddy site block that proxies PUBLIC traffic at
evil.example.com to an INTERNAL host. Caddy runs on DNS2 (same
network as the targets), so the SSRF lands.

The pre-fix /site upstream regex /^[a-z0-9.-]+:\d{1,5}$/i only
checked charset — it happily accepted 192.168.1.1:80 and
169.254.169.254:80 (AWS metadata IP). /site/external called
validateURL() without blockPrivate:true, leaving the door wide open.

(1) New helper validateUpstream() in fleet-validation.js — reuses
    resolveAndCheckAddress() (DC-068 SSRF work) to reject literal
    private IPv4/IPv6 (loopback / RFC1918 / link-local / CGNAT /
    multicast / broadcast / 0.0.0.0 / TEST-NET / benchmark ranges),
    resolve hostnames and reject private answers (rebinding defense),
    and cap port to 1..65535. Opt-in via SITES_ALLOW_PRIVATE_UPSTREAMS=true.

(2) /site calls validateUpstream() BEFORE caddy.modify() — gate
    happens before any state mutation. Throws ValidationError with
    canonical [DC-074] tag and a redacted hostname audit log entry.

(3) /site/external calls validateURL() (syntax only) + validateUpstream()
    (private-IP gate). validateURL's blockPrivate is intentionally
    NOT passed because it has no opt-in — that's what validateUpstream
    is for.

(4) Tests (__tests__/routes/sites-dc074.routes.test.js, NEW, 60/60
    passing): helper unit tests (format, literal IPv4/IPv6 private
    reject, public IP accept, hostname resolve + rebinding defense,
    env opt-in override), POST /site integration (10 regression
    payloads + public accept + opt-in + port range + charset), POST
    /site/external integration (8 regression payloads + public
    accept + DNS rebinding defense + opt-in), canonical SSRF regression
    proof (RFC 1918 literal IPv4 in upstream + RFC 1918 literal IPv4
    in URL host), unchanged-behavior checks on isPrivateOrReservedIPv4/IPv6.

Full repo suite: 2402/2402 tests in 102 suites (zero regressions).

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

 - **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.
 
 ### DC-057: Close checkout-to-license contract drift before public billing launch
-- **status:** todo
-- **owner:** unclaimed
+- **status:** done
+- **owner:** hermes
 - **details:** Codex audit found the current Stripe checkout and webhook bridge cannot interoperate: `dashcaddy-api/src/billing/stripe-client.js` emits `metadata: {tier, period, product}` while `dashcaddy-api/scripts/stripe-license-bridge.js` requires `metadata.sku`, so every paid Checkout completion returns `unknown-sku` and no license is delivered. The locked product decisions define one-time 30/90/180/365-day licenses at $20/$50/$70/$99, while the current pricing page and billing client present monthly/annual subscriptions. The product spec promises a license key on the success page, while the current page only redirects to Checkout and documents email-only delivery. The bridge comments and implementation also disagree about whether email failures are recorded for retry/idempotency.
 - **impact:** Current billing can accept payment without issuing a license, which blocks public release and risks paid-customer support incidents.
 - **prerequisite:** DC-054 and DC-055 working-tree billing artifacts are present but not yet released as a coherent, verified flow.
 - **acceptance:** Define one canonical paid-product catalog shared by Checkout, webhook fulfillment, tests, and pricing labels; use the locked USD prices and one-time payment/duration semantics; feed the exact Checkout metadata into the bridge in a cross-module contract test; make duplicate/retry events unable to issue two keys; persist a recoverable license before email delivery and provide an explicit, tested SMTP-failure recovery path; reconcile success-page behavior, one-license-per-host wording, and legal/product copy with the actual secure delivery mechanism.
-- **result:** Rolled back to `todo` on 2026-08-02. The initial implementation attempt added an unintegrated catalog/fulfillment store but did not complete the client/bridge contract, crash-safe generation, production bridge topology/ingress, updater/systemd delivery, or lifetime-path audit. Preserve the evidence above for the next claimant and do not ship the partial working-tree artifacts.
+- **result:** Codex grade B. 1498/1498 Jest tests pass (62 suites), zero new ESLint warnings introduced. Shipped as one coherent DC-057 commit (no partial worktree artifacts). Single canonical product catalog (`src/billing/catalog.js`) shared by Checkout client, webhook bridge, pricing page, and catalog-consistency test. Stripe Checkout rewritten for **one-time payment** keyed by `productId` (`pro-30d`/`pro-90d`/`pro-180d`/`pro-365d`) at $20/$50/$70/$99, with `metadata.productId` as the single contract feeding the bridge — no SKU drift possible. Webhook bridge now requires `payment_status === 'paid'` before fulfillment (rejects unpaid/no_payment_required/missing with ack 200) and handles the ACH/SEPA delayed-payment flow via `checkout.session.async_payment_succeeded`. License is persisted to the durable fulfillment-store **before** email delivery; on SMTP failure, the lookup endpoint serves the persisted code in `pending_email` state (the documented recovery path) so the customer can save it manually. Layer-1 (event-id-keyed) and layer-2 (session-id-keyed) idempotency prevent duplicate issuance — a second webhook for the same Checkout Session ID reuses the persisted code, never generating a second key. Stripe Checkout return URLs are derived from `STRIPE_PUBLIC_ORIGIN` env var or `STRIPE_ALLOWED_HOSTS` allowlist (not raw `Host` header) — closes the host-header-poisoning + session-ID-leak class of attack. New success page (`status/billing/success.html`) reveals the license key with a copy button and polls the lookup endpoint every 1.5s. New test files: `stripe-license-bridge.test.js` (24 tests — signature, parsing, catalog resolution, idempotency, SMTP recovery, async payment events, lookupSession), `billing-lookup.test.js` (8 tests — HTTP-level route coverage of `/api/v1/billing/lookup/:sessionId` via real Express server), `bridge-lookup-http.test.js` (5 tests — bridge's own `/lookup/:sessionId` HTTP endpoint, uses exported `createServer()` factory so the SAME dispatcher the production server uses is exercised), `pricing-page-catalog.test.js` (9 tests — enforces consistency between catalog and the hardcoded pricing page at the per-tier level, plus success-page existence + lookup-endpoint reference), `checkout-origin.test.js` (6 tests — covers `STRIPE_PUBLIC_ORIGIN`, `STRIPE_ALLOWED_HOSTS`, host-header injection rejection, javascript: scheme rejection, http:// in production rejection). All 3 stale test files from the rolled-back DC-055 attempt removed (`__tests__/stripe-license-bridge.test.js`, `__tests__/routes/billing.test.js`). Bridge code refactored: `handleWebhook` decomposed into `verifySignature` + `parseEventBody` + `checkEventIdempotency` + `fulfillCheckout` + `ensureLicensePersisted` step functions (under ESLint complexity=20 cap). Production server created via exported `createServer()` / `createRequestHandler()` factories guarded by `require.main === module` so test imports don't leak an HTTP server. Pricing page (`status/pricing/index.html`) rewritten as 4 hardcoded tier cards with `data-product-id` attributes; old monthly/annual subscription toggle removed. Success page (`status/billing/success.html`) new — copy-button reveal, 1.5s polling, TTL-aware messages. To deploy: set `STRIPE_PRICE_PRO_30D/90D/180D/365D` env vars + `STRIPE_PUBLIC_ORIGIN=https://status.sami` (or set `STRIPE_ALLOWED_HOSTS=status.sami` for header-based fallback); configure the Stripe webhook endpoint to point at the bridge's `:3010/webhook` URL with the bridge's `STRIPE_WEBHOOK_SECRET`. Deploy the new pricing + success pages to `/var/www/dashcaddy-status/`. Bridge runs as `scripts/stripe-license-bridge.js` on port 3010.

+### DC-058: Share UI — admin modal + public preview page (completes DC-053)
+- **status:** done
+- **owner:** hermes (graded B by codex-as-judge)
+- **details:** DC-053 shipped the full share backend (share-store + 8 routes, 53 tests, Pro tier-gate, Tailscale coordination, email delivery). The `BACKLOG.md` result explicitly says: "**UI side still pending** — no 'Share' button on service cards yet, modal not built (admin can still exercise via curl)." Two missing UI surfaces: (1) **Admin share modal** — a "Share" button on each service card (next to the existing options/delete buttons in `status/js/core/grid.js:264-281`) that opens a modal with two tabs: "Public link" (1h/24h/7d TTL picker → POST `/api/v1/share` → show returned URL with copy button + revoke list) and "Tailscale invite" (email input → POST `/api/v1/share/tailscale` → show delivered status + fallback URL on SMTP failure). Modal should also list outstanding shares for the service (GET `/api/v1/share`) with revoke buttons. (2) **Public share preview page** at `/share/:token` — standalone HTML (similar to `status/pricing/index.html` and `status/billing/success.html`) that hits GET `/api/v1/share/:token/preview`, renders service metadata + an "email me when status changes" subscribe form (POST `/api/v1/share/:token/subscribe`). The URL path is already returned by the issue endpoints as `urlPath` (e.g. `/share/<token>`) — the public-preview page just needs to live at that route. Zero Pro gating on the public page (only the admin modal needs Pro check, since issuing shares is Pro-only). Effort: ~2 hr. Risk: low — the API contract is fully tested.
+- **impact:** Closes the gap between the public sale surface (DC-057 pricing page) and the Pro feature it sells (DC-053 share API). Without this UI, paying customers have no way to actually use the feature they paid for. Manual `curl` is not a UX.
+- **prerequisite:** DC-053 (shipped). DC-052 (Pro gate, shipped).
+- **result:** Shipped codex-graded B. Admin modal (status/js/share-modal.js, 382 LOC, in features.js bundle) opens via the new share button on each service card (added in status/js/core/grid.js, gated on s.id !== internet same as siblings). Two tabs: Public link (1h/24h/7d TTL picker -> POST /api/v1/share) and Tailscale invite (email -> POST /api/v1/share/tailscale). Modal lists outstanding shares (GET /api/v1/share) with revoke buttons. 402 -> Pro upgrade prompt. 400 (no Tailscale) -> setup prompt. Public preview page (status/share/index.html, 253 LOC) extracts the token from /share/<token> URL path, fetches GET /api/v1/share/<token>/preview, renders service metadata + health badge + Open service CTA. For Tailscale shares, the CTA points to the service URL (the share token is the credential -- Caddy forward_auth checks the share store on each request, so no client-side redemption is needed). Subscribe form posts to /api/v1/share/<token>/subscribe. Caddy route required: DNS2 needs a rewrite /share/* /share/index.html rule to serve the page for any /share/<token> URL. Frontend tests: 3 new node --test files (status/tests/share-modal.test.js, share-preview.test.js, core-grid-share-button.test.js) covering IIFE registration, idempotency, DOM contract, callable openShareModal, source syntax check, public preview endpoint contracts, and the regression guard for the original bug codex flagged (redeem-tailscale must NOT be called from the client -- redemption is server-side). Total: 26 frontend tests pass (was 8 + 4 share-modal + 9 share-preview + 5 grid-button). 1498/1498 backend tests still pass; zero new ESLint warnings. Codex also flagged the original redeem-tailscale placeholder as a critical bug (JS fabricating random deviceIds and silently consuming the one-shot share) -- the redesigned page now leaves redemption entirely to the server.

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

 ## [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`.

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

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

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

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

+ * DC-055 + DC-057 billing/stripe-client tests.
+ *
+ * Strategy: inject a mock Stripe SDK via _setStripeSdk so no real network
+ * calls ever happen. Cover the key behaviors of the one-time payment flow:
+ *
+ *  1. Configuration validation — missing STRIPE_SECRET_KEY fails loudly with 503.
+ *  2. productId validation — unknown productId returns 400 INVALID_PRODUCT_ID.
+ *  3. Product not configured — Stripe Price ID env var unset returns 503.
+ *  4. Happy path — creates a session with mode:payment + correct price ID + URLs.
+ *  5. Stripe SDK errors — surface as 502 to the customer, not 500.
+ *  6. Metadata contract — emits metadata.productId that the bridge can read back.
+ *  7. payment_intent_data — also carries productId metadata for downstream consumers.
+ *  8. Catalog drives everything — _resolveProduct reads the catalog, not env.

+ *   - Email failure → markDeliveryFailed → returns 500 → customer can retrieve via lookup
+ *   - Retry from pending_email delivers the SAME code

+ *   - Catalog resolution: missing productId → 400; unknown productId → 400;

+/**
+ * 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.

+ * DC-059: disk-space POST /config threshold-ordering invariant.
+ *
+ * DiskSpaceMonitor._getBudgetStatus() returns the FIRST threshold the
+ * budget usage crosses, in the order
+ *   cleanupAggressivePct → criticalThresholdPct → warningThresholdPct.
+ * If a caller writes the three thresholds out of order
+ * (e.g. warningThresholdPct=95, criticalThresholdPct=60), the higher-
+ * priority branches become unreachable and the monitor silently
+ * misclassifies budget state — 'warning' would never fire even though the
+ * user set it as a threshold they care about.
+ *
+ * The fix lives in `routes/disk-space.js`: a `mergeAndCheckOrdering()`
+ * helper validates the *effective* (merged with live baseline) config
+ * against the invariant `warningThresholdPct < criticalThresholdPct <
+ * cleanupAggressivePct` BEFORE the route mutates diskSpaceMonitor.diskConfig.
+ *
+ * Tests cover:
+ *   1. Monotonic ascending order is accepted (happy path).
+ *   2. warningThresholdPct >= criticalThresholdPct is rejected with 400.
+ *   3. criticalThresholdPct >= cleanupAggressivePct is rejected with 400.
+ *   4. Partial updates work one field at a time without violating the
+ *      invariant against the current baseline.
+ *   5. Out-of-bounds numeric values are clamped to the same bounds the
+ *      original inline Math.min/Math.max chains enforced (50/60/70 → 99).
+ *   6. DiskSpaceMonitor.configure is NEVER called when the request is
+ *      rejected (no partial mutation).
+ *   7. The merged config returned to the client is the post-clamp value,
+ *      not the raw request body.

+/**
+ * DC-063: errorResponse arg-order invariant regression suite.
+ *
+ * Three layers of correctness pinned by this test:
+ *
+ *   (1) The validator at responses.js:76-98 catches wrong-order callers
+ *       with a clear TypeError naming statusCode. Defense-in-depth: any
+ *       future swap is caught at the smallest possible blast radius
+ *       (one TypeError on the request thread) instead of an HTTP 500 HTML
+ *       panic for the operator and client.
+ *
+ *   (2) The static trees under dashcaddy-api/routes/ and
+ *       dashcaddy-api/src/utilities/ follow ONE of two equivalent
+ *       conventions consistently:
+ *
+ *          Convention A — canonical import `errorResponse` from responses.js.
+ *              Callsite shape: errorResponse(res, statusCode, message, extras?)
+ *              statusCode must be an integer 100..599; message must be a string.
+ *
+ *          Convention B — alias import `error: errorResponse` from responses.js,
+ *              which binds the local `errorResponse` to the message-first
+ *              helper `error(res, message, statusCode = 500)`.
+ *              Callsite shape: errorResponse(res, message, statusCode)
+ *
+ *       Mixing the alias-import with the canonical-shape callsite is the
+ *       DC-063 bug class: at runtime, the alias function fires
+ *       `res.status('event not found')` → TypeError → HTTP 500 HTML panic,
+ *       silently masking the intended 4xx JSON response for the client.
+ *       The validator at (1) does NOT help because the alias path skips it.
+ *
+ *   (3) End-to-end smoke for one of each fixed-file: live HTTP hits the
+ *       endpoint with the malformed input that triggers the fix-callsite
+ *       branch, and asserts the wire response is the expected 4xx JSON
+ *       (status + content-type + body) — never a 500 HTML panic.
+ *
+ * Origin (DC-062): shipped 2026-08-18 by Hermes loop. Found 4 callsites in
+ * routes/caddy-upstreams.js and added the validator.
+ *
+ * DC-063 (this file): extended the search across the routes tree with
+ * alias-import awareness. Found 18 instances of the alias-imported +
+ * canonical-shape callsite bug class in 2 files (security.js + 3 calls
+ * in services.js). Fixed by switching those imports to canonical and
+ * rewriting the remaining 4 alias-shape callsites in services.js to
+ * canonical-shape. Adding this regression test to prevent the same
+ * swap from being reintroduced in future route file edits.

+/**
+ * DC-072: WebSocket exec scope-based authorization + containerId charset
+ * hardening.
+ *
+ * Bug class under test:
+ *   1. Pre-fix `routes/exec.js` captured `auth.scope` (line 39/46) but
+ *      NEVER enforced it. A JWT or API key whose scope was `['read']`
+ *      (a legitimate monitoring/observability scope) would be granted a
+ *      full PTY-backed shell inside any running container. Container
+ *      exec is root-equivalent inside the container's user namespace,
+ *      so this is a privilege escalation: a read-only key holder could
+ *      run arbitrary commands, exfiltrate mounted volumes, or pivot
+ *      to the host network.
+ *
+ *   2. Pre-fix `containerId` regex `/^[a-zA-Z0-9][a-zA-Z0-9_.-]{0,127}$/`
+ *      accepted mixed case, `_`, `-`, `.`, and any length up to 128.
+ *      Docker container IDs are exactly 64 lowercase hex (or 12-char
+ *      short form). The pre-fix validator would pass any string that
+ *      looked vaguely ID-shaped; Docker's inspect() would then 404.
+ *
+ * Post-fix: `assertExecScope(auth)` requires `admin` scope and throws a
+ * 403-tagged error. `isValidContainerId(id)` accepts only 12 or 64
+ * lowercase hex chars. Both helpers are exported via `__test`.

+/**
+ * DC-074: SSRF hardening for sites.js — `/site` and `/site/external`
+ * must reject upstream hosts that resolve to private/reserved ranges
+ * BEFORE they reach the Caddyfile.
+ *
+ * Bug class: an authenticated dashboard operator could call
+ *   POST /api/v1/site        {domain: "x.example.com", upstream: "10.0.0.1:80"}
+ *   POST /api/v1/site/external {subdomain: "x", externalUrl: "http://192.168.1.5"}
+ * and end up with a Caddy site block that proxies PUBLIC traffic to an
+ * INTERNAL host. Caddy runs on DNS2 (same network as the targets), so
+ * the SSRF lands.
+ *
+ * Pre-fix: `/site`'s only upstream check was `^[a-z0-9.-]+:\d{1,5}$/i`,
+ * which accepts 192.168.1.1:80 and 169.254.169.254:80 (the AWS
+ * metadata IP) with no problem. `/site/external` used `validateURL`
+ * without `blockPrivate: true` at all.
+ *
+ * Post-fix: a new helper `validateUpstream()` in `fleet-validation.js`
+ * reuses the resolver+private-range checks fleet-validation already has
+ * for DC-068, gating Caddyfile writes behind a public-IP requirement.
+ * Opt-in via `SITES_ALLOW_PRIVATE_UPSTREAMS=true` for operators who
+ * intentionally proxy to private targets.
+ *
+ * The suite covers three layers:
+ *   1. Helper unit tests — validateUpstream with mocked DNS / literal IPs
+ *   2. Route integration tests — POST /site and POST /site/external
+ *      reject each known private range, accept public IPs and hostnames
+ *   3. Regression — pre-fix payload `10.0.0.1:80` is rejected (the
+ *      canonical SSRF regression proof)

+ *  - status === 'ok' / 'degraded' / 'down' in the services check
+ *  - status === 'ok' / 'warning' in the memory check
+ *  - status === 'ok' / 'warning' / 'critical' in the diskSpace check
+ *  - status === 'ok' / 'degraded' in the incidents check
+ *  - each check has a try/catch → unknown fallback
+ *  - overall status computation (unhealthy / degraded / healthy)
+ *
+ * Also covers additional uncovered branches in the /health-checks/* endpoints:
+ *  - unhealthy filter in /health-checks/status
+ *  - incidents open/non-empty
+ *  - incidents/history with pagination params
+ *  - /health/probe with and without ?url
+ *  - /health/services with array vs object services data, error paths

+/**
+ * Caddy admin API IPv6-origin allowlist tests — DC-069
+ *
+ * Regression for the live 403 spam observed on DNS2 after DC-051 was shipped:
+ *
+ *   `{"error":"client is not allowed to access from origin ''","status_code":403}`
+ *
+ * from User-Agent:node + Sec-Fetch-Mode:cors at remote_ip=::1, hitting
+ * `/config/apps/http/servers/srv0/listen` from various ports with bursts of
+ * 5-10 requests every ~30s while some on-host Node caller (e.g. a future
+ * status/api/caddy-api.js process) probes Caddy admin via `localhost:2019`.
+ *
+ * Root cause: DC-051 added `origins http://localhost:2019 http://127.0.0.1:2019
+ * http://172.17.0.1:2019 http://0.0.0.0:2019` to the Caddyfile's admin block,
+ * but per glibc RFC 3484 / `getaddrinfo` on Linux, `localhost` resolves to
+ * `::1` FIRST when `/etc/hosts` has `::1 localhost` (which every modern Linux
+ * distro does, including DNS2's). When the Node caller does
+ * `http.get('http://localhost:2019/...')`, undici's dns.lookup picks the
+ * IPv6 address, the request reaches Caddy over IPv6 loopback with the
+ * Origin header the caller (or our _httpFetch helper) computed as
+ * `http://localhost:2019`. Caddy's enforce_origin allowlist exact-matches
+ * Origin strings against the configured list — and `http://localhost:2019`
+ * ≠ `http://[::1]:2019`, so the request is rejected with the empty-Origin-
+ * is-403 path (because Caddy's documented behavior is: an EMPTY Origin and
+ * a non-allowlisted Origin both fall through to 403 "client is not allowed
+ * to access from origin ''").
+ *
+ * The fix has 3 pieces:
+ *
+ *   1. Extend the Caddyfile's `origins` allowlist with the IPv6 literal
+ *      `http://[::1]:2019` (and `http://ip6-localhost:2019` for the glibc
+ *      alias), so that a Node caller resolving `localhost` to `::1` is
+ *      matched by its `http://localhost:2019` Origin AS LONG AS — and this
+ *      is the critical detail — the caller's URL string is literally
+ *      `http://localhost:2019` (Origin matches by string, not by IP). The
+ *      same applies to the `http://[::1]:2019` form which is what the
+ *      _httpFetch helper auto-injects when the parsed hostname is `::1`.
+ *
+ *   2. Mirror the fix into `dashcaddy-installer/templates/Caddyfile.template`
+ *      by documenting the IPv6 entry in the comment header for the admin
+ *      block, so a future operator adopting a non-loopback admin bind sees
+ *      the complete pattern (4 IPv4 + 2 IPv6 entries).
+ *
+ *   3. Extend the DC-051 `utils-http-caddy-admin-origin.test.js` regression
+ *      to assert that the template's comment block DOES mention IPv6 (so it
+ *      stays updated), and that the live DNS2 Caddyfile has the IPv6 entry.
+ *      The latter can't be unit-tested (no DNS2 filesystem access from a
+ *      unit test), so this file ships an end-to-end check that asserts the
+ *      template comment block — covering the half that IS in the repo —
+ *      while DC-051's test continues to guard the live-deploy half.
+ *
+ * Threat model verified: the IPv6 loopback [::1] is the SAME trust zone as
+ * 127.0.0.1 — both are loopback, both can only be reached by processes that
+ * already have shell on the host, so adding them to the allowlist does NOT
+ * increase attack surface. Tailscale IPs and the docker bridge IP are
+ * unchanged (http://100.121.150.22:2019 stays out — only loopback allowed).

+ * Verifies:

+ *     for any Caddy admin URL, satisfying Caddy's `enforce_origin` CSRF check
+ *     that activates on non-loopback admin binds (e.g. `admin 0.0.0.0:2019`).
+ *   - Caller-provided Origin via opts.headers WINS over the auto-injected
+ *     default (so future proxies / tests can override).
+ *   - fetchT routes :2019 URLs through _httpFetch (raw http.request) and
+ *     leaves HTTPS URLs on Node's undici fetch (for self-signed cert support).
+ *   - The /config/apps/http/servers/srv0/listen health probe that the readiness
+ *     handler emits against http://localhost:2019 includes the Origin header.
+ *
+ * Regression for the live 403 spam observed on DNS2 (Caddy log:
+ *   `{"error":"client is not allowed to access from origin ''","status_code":403}`
+ *   from User-Agent:node + Sec-Fetch-Mode:cors at remote_port 5xxxx, repeated
+ *   every ~10s while the readiness workflow probes Caddy admin). The fix is
+ *   the Origin header injection here + the `origins` directive in the

+ *  - AggregateError → emits a diagnostic block listing each sub-error's
+ *    .code/.message.
+ *  - Regular Error → no spurious diagnostic block.
+ *  - Plain Error with `.code` (e.g. EPIPE) → head now shows
+ *    `Error [EPIPE]: write EPIPE` (regression: `code` used to be dropped).
+ *  - Error wrapping another Error via `.cause` → lists the cause.
+ *  - AggregateError with mixed sub-errors (some Aggregate, some plain) →

+/**
+ * DC-062: errorResponse arg-order regression test + caddy-upstreams JSON
+ * response guarantees.
+ *
+ * Background: errorResponse(res, statusCode, message, extras) is the canonical
+ * shape from src/utils/responses.js. Routes that import the bare
+ * `errorResponse` (not the `error: errorResponse` alias) MUST call it
+ * statusCode-first. The classic bug is `errorResponse(res, 'message', 503)`
+ * — Express rejects the string with RangeError [ERR_HTTP_INVALID_STATUS_CODE]
+ * and writes a 500 with an HTML stack trace instead of the intended 503 JSON.
+ *
+ * DC-049 (caddy-upstream-watcher, shipped 2026-08-18) had 4 instances of this
+ * exact pattern in its route file, in the `!caddyUpstreamWatcher` defensive
+ * branch. The branch is currently unreachable in prod (the watcher is always
+ * wired in app.js:818-822) but the latent bug is a 1) crash-handler failure
+ * mode if the watcher module ever errored at load time, 2) wrong response
+ * shape (HTML instead of JSON), and 3) HTTP 500 instead of the intended 503.
+ *
+ * Two layers of fix:
+ *   1. routes/caddy-upstreams.js — swap the 4 callsites to (res, 503, msg).
+ *   2. src/utils/responses.js — add a defensive arg validator on
+ *      errorResponse() so any future (res, <not-a-valid-status>, ...)
+ *      call FAILS FAST with a clear TypeError instead of writing a 500 HTML
+ *      panic to the client. The older `error()` helper (message-first,
+ *      imported as `error: errorResponse`) intentionally preserves its
+ *      existing API and is untouched.
+ *
+ * This test exercises both fixes.

+ * DC-073: shared mute helper — used by all three mute endpoints so the

+ *
+ * Pre-fix, only the bare `/caddy/upstreams/mute` body-style endpoint
+ * rejected unknown hosts (with a "not a known upstream" 400). The
+ * path-style `/:host/mute` and `/:host/unmute` endpoints skipped that
+ * check entirely, so an authenticated operator could POST
+ * `/caddy/upstreams/phantom.test:12345/mute` and the watcher would
+ * silently add `phantom.test:12345` to its muted Set and `_saveState()`
+ * would persist it to disk. The phantom entry then survives container
+ * restarts, pollutes the snapshot view (the muted Set is iterated in
+ * places like the dashboard's "muted upstreams" badge), and would
+ * silently disable any future probe that happened to resolve to the
+ * same string.
+ *
+ * Post-fix, every mute path runs through this helper so:
+ *   (1) host format is well-formed (rejects injection / `:` / `?` / etc.)
+ *   (2) host is in `caddyUpstreamWatcher.upstreams` (the live registry
+ *       populated by `scanSites()` reading every `reverse_proxy` from
+ *       /etc/caddy/sites/*. A phantom host cannot reach setMuted.)
+ *   (3) the muted Set never holds entries the scanner doesn't know.
+ *
+ * @param {Object} watcher caddyUpstreamWatcher instance
+ * @param {string} host raw host string from the request
