DC-067: [WIP] jest failing at grade time

- Force-exit timer now distinguishes serverClosed from managersStopped.
  Was: if (closed) return → suppressed timer when manager hung after
  server.close fired (the original bug).
  Now: if (managersStopped) return → timer fires only when full drain
  (HTTP close + all managers stopped) completes before the deadline.

- Added _safeEmit() helper that wraps this.emit() so a buggy listener
  throwing during 'shutdown' or 'closed' doesn't abort the shutdown
  sequence. Each failed listener is logged via the structured logger.

- Added 4 new tests covering: hung manager after HTTP close,
  throwing shutdown listener, throwing closed listener, and the
  fast-drain happy path that clears the timer cleanly.

 ### 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).

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

+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-054 + DC-057 stripe-license-bridge tests.
+ *
+ * Strategy: no live network, no live Stripe SDK. We use `jest.mock` to
+ * substitute license-keygen + nodemailer before the bridge loads, drive
+ * handleWebhook() with crafted raw bodies + signatures.
+ *
+ * Coverage:
+ *   - Signature validation (pass / missing / wrong / out-of-tolerance)
+ *   - JSON parse failure
+ *   - Duplicate event-id → 200 idempotent
+ *   - Two different events for the SAME session → single license (layer-2 idempotency)
+ *   - License persisted BEFORE email (crash-safety)
+ *   - Email failure → markDeliveryFailed → returns 500 → customer can retrieve via lookup
+ *   - Retry from pending_email delivers the SAME code
+ *   - Concurrent lease (busy) returns 409
+ *   - Catalog resolution: missing productId → 400; unknown productId → 400;
+ *     product-not-configured → 400
+ *   - Lookup endpoint: not_found, processing, pending_email, delivered, expired TTL
+ *   - Layer-1 + Layer-2 idempotency under Stripe retry

+ * The inbound webhook side lives in scripts/stripe-license-bridge.js

+/**
+ * DashCaddy Stripe license bridge — DC-054 + DC-057.
+ *
+ * Tiny HTTP webhook listener that converts a Stripe Checkout completion into
+ * a DashCaddy Pro license code + a confirmation email. Runs as its own
+ * process (NOT inside the DashCaddy API) so the merchant's Stripe secret
+ * material stays out of the host-side process tree.
+ *
+ * # Wire format
+ *
+ *   POST /webhook
+ *   Stripe-Signature: t=<unix_ts>,v1=<hmac_sha256_hex>
+ *   <raw JSON body>
+ *
+ * The body for `checkout.session.completed` carries:
+ *   { id, customer_email, metadata: { productId }, amount_total, currency, ... }
+ *
+ * # Catalog contract (DC-057)
+ *
+ *   `metadata.productId` is one of the IDs in src/billing/catalog.js:
+ *     pro-30d | pro-90d | pro-180d | pro-365d
+ *   The bridge maps productId → duration via the catalog (single source of
+ *   truth shared with the Checkout client + pricing page). The catalog's
+ *   configured Stripe Price is read via `STRIPE_PRICE_PRO_*D` env vars
+ *   (already documented in the catalog) and is used to validate that the
+ *   product is purchasable (configuredPriceId is not empty) — NOT to
+ *   cross-validate the price against the customer's Stripe session. Price
+ *   verification is intentionally omitted because (a) Stripe webhooks do
+ *   not include expanded line_items by default and (b) trusting the price
+ *   would block legitimate customers during a price rollover.
+ *
+ *   The previous `STRIPE_SKU_*` env vars are REMOVED in DC-057 — operators
+ *   who set them should migrate to `STRIPE_PRICE_PRO_*D`.
+ *
+ * # Generation flow
+ *
+ *   1. Verify Stripe-Signature (constant-time HMAC-SHA256 compare).
+ *      Reject with 400 if the timestamp is more than TOLERANCE_SECONDS
+ *      old, or if any v1 signature is missing.
+ *   2. Look up the event in the per-event idempotency file
+ *      (data/stripe-events.json). If seen, replay the previous response
+ *      status (200) WITHOUT regenerating. This is the layer-1 idempotency.
+ *   3. If the event type isn't `checkout.session.completed`, ack with
+ *      `{delivered: false, reason: "ignored-event-type"}` so Stripe stops
+ *      retrying, and record the event.
+ *   4. Parse the session metadata; resolve productId via the catalog.
+ *   5. CLAIM the fulfillment record (atomic, sessionId-keyed).
+ *      - If the record exists for this sessionId in `pending_email` or
+ *        `delivered` state (e.g. a previous webhook delivery succeeded OR
+ *        saved a license but email failed), we REUSE the persisted license
+ *        code — never generate a second one. This is the layer-2
+ *        idempotency keyed by Checkout Session ID (globally unique, never
+ *        reused even when the same event is replayed).
+ *      - If the record exists in `generating` state and the lease is held
+ *        by a DIFFERENT event (concurrent webhook fan-out), respond 409
+ *        so Stripe retries — only one delivery wins.
+ *   6. SAVE the license code into the fulfillment record
+ *      (data/stripe-fulfillments.json) BEFORE attempting email. This is
+ *      the crash-safety guarantee: even if email fails AND the process
+ *      is killed, the license is durably persisted.
+ *   7. DELIVER the code via SMTP (or dev-console fallback).
+ *      - On success: markDelivered. Lookup endpoint serves the code on
+ *        the success page.
+ *      - On failure: markDeliveryFailed → reverts to pending_email. Lookup
+ *        endpoint serves the code ANYWAY (with a "(email delivery didn't
+ *        complete)" notice) — customer can save it manually. Subsequent
+ *        webhook retries reuse the same persisted code via step 5.
+ *   8. Respond 500 to Stripe ONLY if the license save succeeded but email
+ *      failed AND no successful delivery record exists — Stripe will
+ *      retry. If delivery already succeeded earlier, ack 200.
+ *
+ * # SMTP transport
+ *
+ *   Reuses the same env vars as DashCaddy's notification system:
+ *     SMTP_HOST / SMTP_PORT / SMTP_USERNAME / SMTP_PASSWORD / SMTP_FROM / SMTP_SECURE
+ *   If HOST or FROM is missing, delivery falls back to dev-console mode
+ *   (the bridge logs the full email body so the operator can deliver it
+ *   manually). This is the documented dev path; do NOT enable it in
+ *   production.
+ *
+ * # Exit codes
+ *
+ *   0 — clean shutdown
+ *   1 — fatal startup error (missing secret, port bind failure, no
+ *       products configured)
+ *   2 — runtime error while handling a request (logged, 500 returned)
+ *
+ * # Security notes
+ *
+ *   - Webhook signature MUST verify BEFORE any JSON parsing. The raw body
+ *     is opaque until HMAC checks out.
+ *   - Timing-safe signature comparison (crypto.timingSafeEqual).
+ *   - The fulfillment-store file lives in platformPaths.dataDir (bind-
+ *     mounted in production). Atomic writes + per-mutation mutex.
+ *
+ * Tested in __tests__/billing/stripe-license-bridge.test.js (no live network).

+ * DashCaddy Stripe client — DC-055 + DC-057.
+ *
+ * Thin wrapper around the Stripe SDK for the OUTBOUND side of one-time
+ * license purchasing: creating Checkout Sessions that drive customers to
+ * Stripe's hosted payment page.
+ *
+ * Inbound (webhook) handling lives in scripts/stripe-license-bridge.js
+ * (DC-054 + DC-057) — that runs as its own process so the merchant's
+ * Stripe webhook secret doesn't have to be loaded into the DashCaddy API
+ * host process.
+ *
+ * # Pricing contract
+ *
+ *   One-time payments keyed by `productId` from src/billing/catalog.js:
+ *
+ *     pro-30d   → $20 USD, 30-day license
+ *     pro-90d   → $50 USD, 90-day license
+ *     pro-180d  → $70 USD, 180-day license
+ *     pro-365d  → $99 USD, 365-day license
+ *
+ *   `mode: 'payment'` (NOT 'subscription'). The license is generated once
+ *   per Checkout completion and the customer pastes it into their host.
+ *   No recurring billing, no Stripe Customer object retained beyond the
+ *   session.
+ *
+ * # Configuration (env vars)
+ *
+ *   Required to create sessions — failures are loud:
+ *     STRIPE_SECRET_KEY              — Stripe API secret (sk_live_... | sk_test_...)
+ *     STRIPE_PRICE_PRO_30D           — Stripe Price ID for the 30-day product
+ *     STRIPE_PRICE_PRO_90D           — Stripe Price ID for the 90-day product
+ *     STRIPE_PRICE_PRO_180D          — Stripe Price ID for the 180-day product
+ *     STRIPE_PRICE_PRO_365D          — Stripe Price ID for the 365-day product
+ *     STRIPE_SUCCESS_URL             — (optional) success page URL override
+ *     STRIPE_CANCEL_URL              — (optional) cancel page URL override
+ *
+ *   The Stripe Price IDs map 1:1 to catalog products. A product whose
+ *   Stripe Price ID is unset cannot be purchased (returns
+ *   STRIPE_NOT_CONFIGURED).
+ *
+ * # Metadata contract (DC-057)
+ *
+ *   The Checkout session carries `metadata.productId` (= one of the
+ *   catalog IDs). The webhook bridge reads this field back, maps to the
+ *   catalog, and generates the matching license duration.
+ *
