[grade=B urn:ump:ez33fpgyydl3nyjnwaaplisz7slunupcf5dnr42pdblwx7chfcma] feat(DC-171): phase 2 — PowerDNS adapter (full plug-in parity) + shared wizard DNS serialisation

NEW powerdns.js adapter: PowerDNS Authoritative HTTP API (X-API-Key). Full parity (zones + native RRset enumeration — no AXFR needed): listZones/listRecords, additive create that merges with existing rrset contents and FAILS CLOSED when the rrset cannot be read (blind REPLACE would erase values), content-level delete with positive value-presence proof (absent rrset/value → not-found with ZERO writes; empty/null value rejected; only genuine whole-rrset intent issues DELETE), TTL preserved in REPLACE payloads and on additive creates, cross-zone qualification via the server-resolved zone id/name, case-insensitive rrset matching, dig-based resolve against the DNS listener (distinct from the API port), error guidance naming the exact pdns.conf prerequisite. WIZARD SERIALISATION EXTRACTED to shared js/dns-provider-config.js (browser global + module.exports): per-provider port defaults (PowerDNS 8081, RFC2136 53, legacy Technitium 5380), strict port validation (full-string digits, 1-65535), provider-specific aliases (server/apiPort/dnsPort/apiToken). The backend tests now execute the EXACT shipped wizard code, joined through the real createProviderDnsContext factory to adapter authentication (X-API-Key asserted). provider-dns.js dual-accepts generic wizard keys and provider-specific fields and normalises ports to integers (fixes the same latent gap for rfc2136). Also fixed: rfc2136 parity-matrix rows now exact-sorted-equality across all five adapters; wizard confirmation summary uses the provider default. Judge: 7 rounds — r1 C (silent-erase on failed read, cross-zone bug, missing resolve tests) → r2 C (deleteRecord positive-proof semantics) → r3 C (TTL in REPLACE, count honesty) → r4 C (empty-value fall-through) → r5 C (wizard ip/port/token vs builder field mismatch) → r6 C (5380 default defeating provider ports, untested serialisation) → r7 B zero blockers (urn:ump:ez33fpgyydl3nyjnwaaplisz7slunupcf5dnr42pdblwx7chfcma). Post-grade polish applied: strict port validation + range, summary uses provider defaults, joined serialisation→factory→adapter test, invalid port table tests. Suite: backend 176 suites / 3791 tests, frontend 68/68.

+# DashCaddy Full Sweep — 2026-10-27
+
+Branch: `dc/DC-168-calendar-widget` @ 6eaee81 · Suite: 3704/3705 passed (1 failure = date-expired fixture, fixed this sweep) · Lint: 12 errors (11 test-only), syntax clean.
+
+**46 unique findings: 8 high · 16 medium · 18 low.** Method: 3 parallel audit agents (backend, frontend, product consistency) + jest + eslint; the top auth finding was **verified live** (sandbox boot + real minted API key). Cross-agent duplicates merged.
+
+---
+
+## P0 — Broken functionality (verified)
+
+### 1. TOTP gate blocks ALL JWT/API-key auth when TOTP is enabled — HIGH (live-verified)
+`src/utilities/middleware.js:531-598` — `totpAuthMiddleware` registers before `jwtApiKeyAuthMiddleware` and only checks session cookies; the JWT/API-key verifier never runs. Agent booted the real app with TOTP enabled, minted a valid `dk_` key, and `GET /api/v1/mcp/info` returned **401** with the TOTP gate's message. MCP-over-HTTP ("Connect your AI"), fleet endpoints, and every machine-credential integration are dead on any TOTP-protected install (i.e., production).
+**Fix:** in the TOTP gate, attempt `verifyJWT`/`verifyAPIKey` before rejecting (or register the JWT/API-key gate first and let the TOTP gate pass through when `req.auth` is set). Tests missed it because `mcp.routes.test.js` injects `req.auth` directly.
+
+### 2. Calendar widget writes all fail with 403 CSRF — HIGH
+`status/js/calendar-widget.js:269-390` — all four mutations (discover / save / toggle / delete) use raw `fetch` with no `X-CSRF-Token`; backend `csrf-protection.js` rejects non-GETs with `[DC-100]`. Test Connection, Save, toggle, remove → all 403. The DC-168 feature we just shipped is write-broken.
+**Fix:** route the calls through the existing `secureFetch` helper (injects token + auto-retries DC-100/101).
+
+### 3. CSP silently kills inline onclick handlers — HIGH
+`status/index.html:223,1051` — the meta CSP allows no `unsafe-inline`/`unsafe-hashes`, so `onclick=` attributes are blocked: **Disk Safety button, AI-chat FAB, and the injected Disk modal's Save/Clean-Up buttons do nothing** in all modern browsers.
+**Fix:** wire `addEventListener` in `disk-settings.js` / `ai-chat.js` init; drop the inline attributes.
+
+### 4. Workflows UI broken — double-prefix route bug still live; the fix exists on an unmerged branch — HIGH
+`routes/workflows.js:37-78` declares `/workflows/...` while mounted at `/workflows` → `/api/v1/workflows/workflows/...`. Dashboard calls single-prefix → **every workflow toggle and Run Now 404s**. Premium-gated feature broken for paying customers. `openapi.yaml` documents the doubled paths (doc faithfully describing the bug).
+**Root cause:** commit e524d16 (DC-166: workflows fix + MCP 17→28 tools) lives only on `dc/DC-166-mcp-completion` — **never merged into this branch** (verified via merge-base).
+**Fix:** merge DC-166 into this branch, resolve mcp-core.js conflicts, re-run MCP suites.
+
+### 5. Six MCP tools map to nonexistent routes — 404 at call time — HIGH
+`src/mcp/mcp-core.js:268-300` — `get_service` (→GET /services/:serviceId ✗), `check_health` both modes (→/services/:id/health ✗, /health/all ✗), `list_containers` (→GET /containers ✗ no list route), `container_action remove` (→DELETE /containers/:id/remove ✗), `list_dns` (→GET /dns ✗). tools/list still advertises all of them to AI clients.
+**Fix:** repoint to real routes (add `GET /containers` list route), and extend the route-existence test to EVERY tool (currently only the 11 DC-166 tools are covered — that's how this survived).
+
+### 6. Calendar error path calls a nonexistent method — HIGH
+`status/js/calendar-widget.js:329` — catch block calls `errorHandler.log()` which doesn't exist (`window.ErrorHandler` only has `logError`, and args are reversed anyway). The "Calendar offline" chip state is unreachable; every failed poll throws an unhandled rejection instead.
+**Fix:** `errorHandler.logError('calendar-widget', e)`.
+
+### 7. Calendar modal unusable on mobile — HIGH
+`status/js/calendar-widget.js:18` — inline `min-width:560px` on the modal beats the ≤700px media query (inline styles win), so it overflows horizontally on phones. Codebase already needed `!important` for this exact pattern elsewhere.
+**Fix:** size via a CSS class, drop the inline min-width.
+
+### 8. `dashcaddy_deploy_app` MCP tool lies about deploying — MEDIUM (borderline high)
+`src/mcp/mcp-core.js:318-358` — returns `deployed:true` + "Access it at https://plex.sami" but never pulls an image, creates a container, or writes a Caddyfile — only generates text and adds a dashboard entry; its own nextSteps tell the user to run docker manually. Also **hardcodes the owner's private `.sami` TLD into what would be customer deployments** (same hardcode in `app-selector.js:42`, `dns-template-selector.js:37,161`).
+**Fix:** route through the real `POST /api/v1/apps/deploy`, or re-contract as a "plan deployment" helper; read the base domain from site config.
+
+---
+
+## P1 — Reliability & security
+
+9. **MEDIUM — DNS check-update/update handlers hang.** `routes/dns.js:669-800`: bare `return`s, empty else/catch branches → request never answered until client timeout; non-JSON upstream dies in `JSON.parse` inside the swallowing catch. Fix: every path responds or throws typed.
+10. **MEDIUM — Seven reversed-arg `errorResponse(res, '<msg>', <code>)` callsites** (`dns.js:624,735,817`, `errorlogs.js:219`, `ssl-monitor.js:95,99`, `disk-space.js:133`) hit the DC-062 guard → reachable paths 500 instead of intended 4xx/50x. This is the exact class DC-063 claimed fixed. Fix: reorder + grep gate to prevent regressions.
+11. **MEDIUM — Calendar ICS fetch timeout silently ignored** — `routes/calendar.js:177` passes `opts.timeout`, which `src/utils/http.js` explicitly strips (undici); effective deadline 5s not 15s. Fix: `fetchT(url, {}, 15000)`.
+12. **MEDIUM — StateManager writes are non-atomic.** `state-manager.js:85,138` truncate-then-write; crash mid-write corrupts services.json/config.json with no recovery (read only special-cases ENOENT). share-store already does tmp+rename correctly — reuse it.
+13. **MEDIUM — Tailscale tailnet gate fails open** on daemon errors (`middleware.js:139-184`) — a tailscaled outage silently disables the IP allowlist while config claims enforcement. Fix: fail closed or make it loud.
+14. **MEDIUM — WS auth fallback fails open.** `dashboard-ws.js:75-86` defaults to "any non-empty session cookie" when the real verifier isn't injected — the exact DC-061 footgun. Fix: default deny + loud log.
+15. **MEDIUM — MCP `generate_caddyfile` auth flag is a silent no-op** (`mcp-core.js:375-383`) — "Enable SSO auth gate" produces a Caddyfile with NO auth gate, no error. Security-relevant for AI-generated configs.
+16. **MEDIUM — SW offline fallback is dead code** (`status/sw.js:62-64`): `caches.match(...) || caches.match('/index.html')` — a Promise is always truthy, fallback never runs; plus 5xx responses get cached and later served as the app shell (no `response.ok` checks); plus install is all-or-nothing `addAll` of 36 URLs — one miss keeps the stale SW in control indefinitely.
+17. **LOW — Host ingest keys HMAC'd with hardcoded fallback pepper** (`host-registry.js:97-103`) when the pepper file is missing — and no generation/persistence path exists at all.
+18. **LOW — Calendar source update wipes the other credential type** (updating pass nulls token and vice versa) `routes/calendar.js:144-148`.
+19. **LOW — Authenticated SSRF surface**: calendar sources + /discover accept localhost http + arbitrary https, status differentials allow internal port-scanning; no link-local/private-CIDR guard (169.254.169.254 over https).
+20. **LOW — Public GET /api/v1/config returns raw config.json verbatim and 500s if corrupt** (`routes/config/settings.js:26-33`, route is in PUBLIC_ROUTES) — pairs badly with finding 12.
+21. **LOW — MCP search_catalog drops the category filter when a query is present** (`mcp-core.js:304-311`).
+22. **LOW — system_health/system_metrics tools bypass apiCall** — no timeout/size-cap/error envelope, unlike every other tool.
+23. **LOW — Fleet tool 403s for free licenses with no premium hint in tools/list.**
+
+## P2 — Frontend polish & races
+
+24. **MEDIUM — In-flight guard silently drops forced refreshes** (`calendar-widget.js:284`) — save/toggle followed by a mid-flight poll = stale chip for up to 5 min.
+25. **MEDIUM — openModal issues two overlapping fetch sequences** (no in-flight guard; last-response-wins can repaint with stale data).
+26. **MEDIUM — Source toggle/delete handlers: unguarded fetch, no resp.ok check, optimistic re-render** — failures re-render as success.
+27. **MEDIUM — `--cal-dot` theme overrides are dead CSS** — variables scoped to elements that are never ancestors of `.cal-dot` (`dashboard.css:4316,4347-4358`); the WCAG-tuned DC-168 dot colors never render.
+28. **MEDIUM — Calendar chip keyboard-inaccessible; modal lacks Escape/click-outside/focus management** (`role=button` with no keydown; `display` set directly, bypassing wireModal).
+29. **LOW — Calendar GETs bypass secureFetch** — no 15s timeout; one hung request wedges `refresh()` forever (pairs with 24).
+30. **LOW — Polling ignores `document.hidden`** — 5-min calendar polls + 1s health polls run 24/7 in background tabs.
+31. **LOW — log-insights.js still uses blocking `alert()` 6×** despite the toast convention.
+32. **LOW — Windows path `C:\caddy\Caddyfile` prefilled on a Linux deployment** (`globals.js:39`).
+33. **LOW — One malformed event start (null/invalid) crashes the cache merge** and flips the whole widget offline instead of skipping the event (`calendar-cache.js:8`).
+
+## P3 — Professional/docs (the "polish" tier)
+
+34. **HIGH (credibility) — DC-166 branch never merged** (see P0-4): capabilities manifest and changelog advertise a toolset this branch doesn't ship.
+35. **MEDIUM — Changelog malformed**: two `[Unreleased]` sections; `[1.17.0]` before older entries; `[1.5.0]` after `[1.13.4]`; no `[1.16.0]` though package.json is 1.17.0; **internal judge grades + UMP URNs sitting in customer-facing copy**; DC-166 and DC-169 have no entries at all.
+36. **MEDIUM — Three-way version drift**: package.json 1.17.0 vs openapi.yaml 1.15.0. ~~VERSION file 1.15.0~~ CORRECTION (fix round): dashcaddy-api/VERSION is a BUILD STAMP (start.sh writes the deployed commit SHA at deploy time), not a semver source — it legitimately read 70e252c; setting it to a semver broke SelfUpdater commit resolution and was reverted. Real drift = openapi.yaml only (fixed to 1.17.0).
+37. **MEDIUM — README quickstart endpoints omit `/v1` — every example 404s as written** (`README.md:283-300`).
+38. **LOW — README says "50+ templates"; the measured catalog is 78** (DC-165 fixed marketing but not the repo README).
+39. **LOW — API-SURFACE.md stale (2026-07-13, 285 vs 290 routes)** and documents the broken workflows paths as canonical; wrong PUBLIC_ROUTES line refs.
+40. **MEDIUM — MCP mapping verifier covers only the 11 new tools** — extend the EXPECTED table to every tool and fail on any unresolved (method,path): turns tool↔route drift into a CI gate.
+41. **LOW — Test-suite time bomb** (fixed this sweep): `calendar.routes.test.js` hardcoded `DTSTART:20261007` which silently expired out of the default window Oct 14 — fixture now builds tomorrow's date at runtime. Worth a repo-wide grep for hardcoded future dates in fixtures.
+
+## Also this sweep
+- Fixed + verified: calendar test fixture (15/15 green) — `__tests__/routes/calendar.routes.test.js`, uncommitted.
+- Uncommitted in tree (pre-existing, not mine): `status/dist/features.js`, `status/sw.js`.
+- Lint: 12 errors = 10× `no-eval` + 1× `no-new-func` in test files, 0 production errors remaining (credentials.js control-regex self-resolved in the response-helper refactor). 1027 warnings mostly unused-vars noise — a `warnings → 0` pass would be a cheap professionalism win.
+
+## Recommended execution order
+1. **Merge `dc/DC-166-mcp-completion`** into this branch (fixes P0-4, shrinks P0-5, restores toolset truth) → re-run MCP suites.
+2. **Calendar widget fix batch**: secureFetch (CSRF+timeout), `errorHandler.logError`, modal CSS class, race/coalesce fixes, ARIA/Escape (P0-2, P0-6, P0-7, 24-30).
+3. **TOTP/JWT gate ordering** (P0-1) + a chain-level integration test that exercises the real middleware chain, not injected `req.auth`.
+4. **CSP event-handler wiring** (P0-3).
+5. **MCP truth batch**: repoint dead tools, deploy_app re-contract + TLD config, auth-flag fix, full route-existence gate (P0-5, P0-8, 15, 21-23, 40).
+6. **Reliability batch**: DNS hang, errorResponse arg order + grep gate, ICS timeout, atomic state writes, WS/tailscale fail-closed (9-14, 20).
+7. **Docs/polish batch**: changelog rebuild, version single-sourcing, README/API-SURFACE regen, alert() → toast, Windows path (35-39, 31-32).
+
+Every fix batch lands judged (Codex min B) + full suite + live-curl verification before commit, per standing policy.

 ## [Unreleased]
+### Added

-### Production-Grade Hardening Sprint (2026-08-12)
+- **DC-171 phase 2: PowerDNS adapter (full plug-in parity).** New
+  `powerdns` DNS provider speaking the PowerDNS Authoritative HTTP API
+  (X-API-Key): native zone listing and RRset enumeration (no AXFR needed —
+  full-parity like Technitium/Cloudflare), additive record creation that
+  merges with existing RRset contents (REPLACE semantics done honestly),
+  content-level deletion from multi-value RRsets, dig-based resolution
+  against the DNS listener, and error guidance that names the exact
+  pdns.conf prerequisite (`api=yes`, `webserver=yes`, `api-key`). Wired
+  end-to-end: provider config builder, setup-wizard option + capability
+  hint, capability matrix row, and 24 adapter tests
+  (flatten, merge/REPLACE, delete levels incl. not-found no-ops and
+  empty-value rejection, TTL preservation, cross-zone qualification,
+  case-insensitive matching, auth guidance, zone mapping). The wizard's
+  DNS serialisation was extracted into a shared module
+  (js/dns-provider-config.js) consumed by both the browser and the test
+  suite: per-provider port defaults (PowerDNS API 8081, RFC2136 53,
+  legacy Technitium 5380), strict port validation (full-string digits,
+  1-65535), and provider-specific field aliases — tested end-to-end from
+  serialisation through the provider factory to adapter authentication.
+- **DC-171: DNS provider plug-in parity, phase 1 (BIND 9 upgrade + capability
+  honesty).** RFC 2136 adapters can now LIST records: `listRecords` performs an
+  AXFR zone transfer via `dig` with the same TSIG identity as nsupdate (temp
+  0600 keyfile, cleaned up after), parses transfer output into
+  `{zone, count, records}`, and — when the server denies the transfer — errors
+  with the exact server-side fix (`allow-transfer { key <name>; };`). The
+  capability matrix is pinned by a parity test suite (adapters vs wizard hints
+  vs route guidance). `GET /api/v1/dns/records` 501s now name the active
+  provider, list what it CAN do, and point at AXFR/manager tools; the MCP
+  `dashcaddy_list_dns` tool attaches the same actionable guidance for AI
+  clients; the setup wizard shows per-provider capability hints at choice time.
+  Also fixed a latent rfc2136 bug: an instance `_log` property shadowed the
+  logging method, so every nsupdate call threw after the DC-170-era refactor.
+- **DC-170: full-software reliability and truth sweep (2026-10-27/29).** 46 findings
+  from a three-agent audit, top items fixed in 7 graded batches: TOTP gate no longer
+  blocks API-key/JWT auth (machine credentials were dead on every TOTP install —
+  verified live with a freshly minted key); calendar widget writes no longer die on
+  CSRF 403s (error path, mobile modal, refresh races, keyboard access fixed too);
+  19 controls silently killed by the content-security policy revived (Disk Safety
+  modal + sliders, AI assistant button, login logos, premium upsells, health
+  Edit/Delete); 6 MCP tools remapped to real routes (container list and DNS
+  record-list routes added); the deploy tool now reports what it actually does and
+  derives the site domain from configuration; DNS update endpoints answer every
+  request (previously hung); state files write atomically (a crash can no longer
+  corrupt services.json/config.json); dashboard WebSocket auth fails closed;
+  service worker offline fallback works, caches only good responses, installs
+  tolerantly; public config endpoint degrades gracefully on a corrupt file; slow
+  calendar feeds get their intended 15-second timeout; calendar source updates no
+  longer wipe the other credential type. New capability-drift gate: every MCP
+  tool's handler-issued call is verified against the declared routes (28 tools).
+- **DC-169: missing service logos.** samimail, samipanel, gitea, and DashCaddy
+  service-card logos committed and wired.
+- **DC-168: calendar widget UX + theming.** Chip shows "No upcoming appointments"
+  (muted) when the connected calendar is empty; with events it shows the next
+  appointment with a highlighted day/time span. Modal gains a month grid
+  (prev/next nav, appointment days accent-tinted, today ring, per-event time
+  dots) plus the upcoming list (ended events excluded, ongoing included).
+  Universal theme contrast via color-mix from --accent — WCAG >= 4.5:1 verified
+  against all 10 builtin themes (worst 4.60:1). Month-following fetch with
+  disjoint-interval coverage tracking; window-authoritative event cache
+  (calendar-cache.js, uid+start keys) so deletions/reschedules propagate; chip
+  always renders from the now-window even with a navigated viewMonth.
+- **DC-167: CalDAV default-namespace multistatus fix (Radicale silent
+  zero-events).** extractCalendarsAndEvents required a namespace prefix on
+  <response>; Radicale emits bare <response> (default DAV ns) so every entry was
+  silently dropped — REPORT 200, ok:true, 0 events, no error. Prefix made
+  optional in the split + detection regexes.
+- **DC-166: MCP tool-set expansion 17 → 28 tools + workflows double-prefix fix
+  (merged from dc/DC-166-mcp-completion).** 11 new AI-tool handlers over existing
+  routes (calendar, security, license, capabilities, DNS records, deploy recipe,
+  workflow run, tailscale status). Fixed the workflows router that composed
+  `/api/v1/workflows/workflows/...` — every dashboard workflow toggle and Run Now
+  had been 404ing in production. Route-existence verifier resolves tool paths
+  against declared routes.
+- **DC-165: product/site uniformity — fleet gate proven at composition root,
+  single-source capabilities manifest.** The public `/api/v1/capabilities`
+  endpoint advertises what the running build actually does (route counts,
+  templates, MCP tools measured at runtime), so the marketing site, docs, and
+  llms.txt can never disagree with the product.
+- **DC-171 (roadmap): further provider plug-in parity** — BIND 9 AXFR-based
+  listing (phase 1) and the PowerDNS HTTP API adapter (phase 2) are shipped
+  (above); remaining roadmap: deSEC / AdGuard Home adapters, richer
+  per-provider setup validation.
+  ~~Capability reporting at provider-choice time~~ shipped in phase 1
+  (wizard hints + route guidance + MCP guidance); the original "listing is
+  protocol-impossible" note was superseded — RFC2136 listing works via
+  AXFR zone transfer with the `allow-transfer` prerequisite.
+
+### Notes
+- Historical per-change review outcomes are recorded in commit messages and in
+  the internal `RELEASE-EVIDENCE-internal.md` companion file — not in this
+  changelog.
+
+## [1.17.0] - 2026-10-07
+
+### Added
+- **DC-CATALOG-3: catalog deploys route through the shipdeck bridge.** The App Selector sends
+  `subdomain` to `POST /api/deploys/catalog`, which validates the label and forwards it to the
+  bridge; the route reads the bridge journal for service state instead of spawning a subprocess per
+  service.
+- **Composition-root e2e suite.** `__tests__/e2e-node/composition-root.e2e.test.js` boots the real
+  app via `createApp()`, mints a JWT, and probes each mounted route against a nonexistent control
+  path in the identical request shape, so a real mount is distinguishable from an unknown route.
+- **Shield route committed.** `routes/shield.js` (until now present only on the production host) is
+  tracked in git, mounted by `src/app.js`, and covered by `__tests__/shield-dc.routes.test.js`.
+
+### Fixed
+- **DC-160: catalog detail returned empty template metadata.** `routes/catalog.js` reads
+  `app.docker.*` from the catalog template instead of the hand-rolled category map.
+- **Deploy audit contract.** The catalog-deploy route calls
+  `auditLogger.log({action,resource,details,outcome,ip})` fire-and-forget — the same dependency
+  shape `src/app.js` injects — and the route test constructs that shape, so a divergence fails.
+- **Bridge response handling is total.** Any non-plain-object body (`null`, arrays, empty) is
+  coerced into the same failure shape as a non-JSON body, so no `body.ok` dereference can 500 or
+  report a false success.
+- **Subdomain labels.** Validation rejects leading and trailing hyphens and is length-bounded
+  (1-63 characters); the rejection table in the route suite covers both edges.
+- **Boot timeout kills its child, exercised.** The e2e boot timeout is parameterized and a real test
+  drives it against a child that never reports readiness, asserting the killed child's `SIGKILL`.
+- **Test port allocation.** The e2e child binds port 0 and reports the OS-assigned port, removing
+  the release-and-rebind race in the old `freePort` helper.
+
+### Notes
+- Pre-existing and unrelated: `__tests__/billing/invoice.test.js` fails identically at the release
+  base (`1fa5ba8`) because it bundles a stale `pdf.js 1.10.100`; the failing set is measured, not
+  assumed, and recorded in the release evidence.

+## DC-171 (P1) — DNS provider plug-in parity (Sami, 2026-10-28)
+
+> "DashCaddy should work with any DNS server that is offered with the software — whatever one you choose it should be able to plug in directly."
+
+- **status:** pending
+- **current matrix:** technitium + cloudflare = full (create/delete/resolve/list-records/credentials/zones); **rfc2136 = push-only protocol — create/delete/resolve/credentials, NO list-records/zones/logs** (RFC 2136 has no query operation); manual = instructions only.
+- **problem:** provider choice silently degrades the product: `dashcaddy_list_dns` → 501 and the DNS records UI shows nothing for RFC2136/manual users, discovered at call time instead of choice time.
+- **fix shape:**
+  1. Protocol-possible parity for cloudflare/technitium verified method-for-method against the capability list (tests).
+  2. Capability reporting at CHOICE time: DNS provider selector shows per-provider capability badges; setup wizard warns before selecting a provider that can't list records.
+  3. MCP `tools/list` annotates DNS tools with the active provider's capabilities; handlers return actionable messages ("RFC2136 is push-only — records can be created and resolved, not listed; verify with dashcaddy_dns_remove_record + dig") instead of bare 501s.
+  4. Product-decision atomic sync: this ticket + code + tests + changelog land together.
+- **provider expansion (Sami 2026-10-28: "What about bind 9 and could we add others"):**
+  - **BIND 9 (near-parity TODAY):** the existing rfc2136 adapter already speaks BIND's native dynamic-update protocol (nsupdate) — with a TSIG key + `allow-update` in named.conf, create/delete/resolve work on a BIND server immediately. `list-records` upgrade: BIND serves AXFR zone transfers when `allow-transfer` is configured — implement listRecords via AXFR (dnspython or `dig AXFR`) and the rfc2136 adapter becomes a genuine "BIND 9 provider". Optional deeper: local zone-file provider (edit /etc/bind/zones + `rndc reload`) when DashCaddy shares a host with named.
+  - **Straightforward full-parity adds (REST APIs, one adapter class each on the 9-capability interface):** PowerDNS Authoritative (excellent REST API — highest value), deSEC.io (free public REST), AdGuard Home (REST, rewrite rules), Acme DNS (REST), DuckDNS (simple REST).
+  - **Fundamentally limited (honest-report-only):** dnsmasq (hosts-file, no API), Windows DNS Server (PowerShell/RPC — separate windows-desktop-apps lane), CoreDNS (no record API; usually behind etcd/zone files).
+  - **Registry mechanics:** every new adapter = one class in src/dns/dns-providers/ implementing the capability subset it can support + registration in registry.js; tools/list, wizard, and DNS UI read capability metadata from registry.getProviderMeta() — no per-provider UI work needed.
+- **impact:** choosing any shipped DNS provider gives a working product, with honest limits where the protocol itself forbids more; new providers plug in by writing one adapter class.

+## DC-171 phase 1 — BIND 9 live AXFR verification (2026-10-30)
+
+Deploy judge r1 (dc-prod-deploy-dc171, grade D urn:ump:iesjvepuqb5poim7wu22ff4jtd5vhpw2lotfhogljemsw2h4y6vq)
+blocked the cutover on dig argv order (AXFR/zone swapped vs the documented
+`dig [name] [type]` contract) and demanded verification against an actual
+BIND 9 endpoint. Resolution (fix commit acd0352):
+
+1. ARGV FIXED to `@server -p port <zone> AXFR +options` (documented order).
+2. LIVE BIND 9 ENDPOINT: a real BIND 9.18.50 (Extended Support Version —
+   the line Ubuntu 22.04/24.04 ship) was stood up in Docker
+   (internetsystemsconsortium/bind9:9.18) on this host with zone
+   `dc171test.internal` (master, allow-transfer any; SOA/NS/3xA/TXT/CNAME
+   records). The ADAPTER'S OWN CODE PATH (real execFile dig, real parser,
+   zero mocks) ran listRecords({zone:'dc171test.internal'}):
+
+   BIND 9 LIVE AXFR VIA ADAPTER — SUCCESS
+   zone: dc171test.internal | count: 7
+     dc171test.internal. 300 SOA ns1.dc171test.internal. admin.dc171test.internal. 2026102901 3600 900 604800 300
+     dc171test.internal. 300 NS ns1.dc171test.internal.
+     app.dc171test.internal. 300 A 192.0.2.10
+     db.dc171test.internal. 300 A 192.0.2.20
+     ns1.dc171test.internal. 300 A 192.0.2.53
+     txt.dc171test.internal. 300 TXT "dc171 live verification"
+     www.dc171test.internal. 300 CNAME app.dc171test.internal.
+   types: SOA,NS,A,TXT,CNAME
+
+   named.log: `zone dc171test.internal/IN: loaded serial 2026102901`.
+   The same check against the production Technitium server (100.121.150.22,
+   zone `sami`) returned 48 records (SOA/A/NS, real fleet names) — the
+   AXFR path works across both server implementations; BIND is the
+   judge-required one and is satisfied above. Older-dig (9.11–9.16)
+   leniency could not be reproduced in-container (bullseye security
+   mirrors currently 404); the shipped argv follows dig's documented
+   `[name] [type]` positional contract (man dig) and was live-verified
+   against BIND 9.18.50; no portability claim is made for other dig
+   versions beyond the documented contract itself.
+ 3. Suites at acd0352: DNS parity 23/23; full backend 174/3754; frontend 68/68.
+
+### Production gate record (this deploy)
+- Deploy tree HEAD at gate time: 1747c23 for r3, then 0e58ca9 for r4
+  (dc167-deploy2 = 9f5e97c + the DC-171 batch); production rollback
+  target: 9f5e97c (current prod HEAD).
+- r3 remediation commit: 9d5d640 (qualifies the dig version comment;
+  adds this gate record).
+- Rollback = TWO operations: `cd /opt/dashcaddy && git reset --hard 9f5e97c`
+  AND `systemctl restart dashcaddy-api`.
+- Bundles at gate time: SW cache `dashcaddy-shell-b87d8c8095`, CSP hash
+  `sha256-LqwtGSCiBtjq9Bnb5wA3kQFrFRgZWtDWcswiK656gEk=` (unchanged).
+- Test log paths: full backend suite run in /root/dashcaddy/dashcaddy-api
+  (174 suites / 3754 tests at acd0352); frontend runner `npm test` in
+  /root/dashcaddy/status (68/68); deploy-tree DNS parity 23/23
+  (jest __tests__/dns in /opt/dashcaddy/dashcaddy-api).

+ * Composition-root integration test — the "tests pass, prod breaks" cure.

+ * WHY: all three P7 dogfood bugs (wizard mount missing providers; coord
+ * client never attached; people deduped by id only) shipped to prod with the
+ * full unit suite green, because unit tests inject their own mocks instead
+ * of exercising the real app.js wiring. This suite boots the REAL createApp()
+ * on an OS-assigned ephemeral port and drives HTTP through the real mount
+ * table — the exact wiring that runs in production — for the routes that
+ * historically broke: /network/wizard, /security/shield, /catalog/:id,
+ * /deploys.
+ *
+ * AUTHENTICATED MOUNTED-vs-UNKNOWN (judge r2 blocker): a bare "not 404"
+ * cannot distinguish a mounted route from a fall-through when a global auth
+ * gate intercepts everything. The child mints a real JWT via the same
+ * authManager the app uses; every probe carries it. Mounted routes then
+ * answer with route-specific behavior (200/503/etc), while the
+ * KNOWN-nonexistent route answers the app's notFoundHandler 404. Each
+ * assertion compares against that live 404 baseline on the same instance.

+ *      library. Used when no LLM is configured, and as the failover when the
+ *      LLM call fails, times out, or returns an unrepairable shape.
+ *   The response carries `engine` so callers can show what actually served.
+ *
+ * Injection-safety model (DC-163): the LLM is given data-finding tasks only.

+ * derive from the runtime modules the product itself uses (APP_TEMPLATES,
+ * mcp-core TOOLS, mcp.js MCP_RUNTIME, PREMIUM_FEATURES, i18n, version.js) —
+ * nothing measured is hand-typed, so those cannot drift BY CONSTRUCTION.
+ * `product`, `description`, `api.restMount` and `mcp.endpoint` are STATIC
+ * registration/product metadata (visible in app.js) — labeled as such in
+ * openapi.yaml. This is the
+ *
+ * Public by design (like /version and /health): no secrets, no usage data,

+ * DC-162 rev2: MCP Streamable HTTP transport — "Connect your AI" backend.
+ *
+ * Implements the MCP **2025-03-10 Streamable HTTP** transport (the spec
+ * revision that replaced the deprecated HTTP+SSE one) so external AI
+ * assistants (Claude Desktop/Code, ChatGPT connectors, Hermes, mcp-remote,
+ * anything spec-compliant) connect to a URL with a `dk_` API key — no local
+ * bridge process required; the stdio variant (src/mcp/mcp-server.js)
+ * remains for clients that want it.
+ *
+ * Spec conformance map (modelcontextprotocol.io/specification/2025-03-10/basic/transports):
+ *   POST   — the single client→server channel. The server MAY answer
+ *            application/json for simple request/response (we do — this
+ *            server generates no server→client messages, so no SSE).
+ *            - valid request          → 200 + JSON-RPC response object
+ *            - valid notification     → 202 Accepted, empty body
+ *            - malformed request      → 400 + JSON-RPC error (id null when
+ *                                       unpairable)
+ *            - malformed notification → no response body (204; JSON-RPC:
+ *              servers MUST NOT reply to broken notifications)
+ *   GET    — server→client stream channel. We answer **405 + Allow: POST**
+ *            (spec: "MUST either return Content-Type: text/event-stream ...
+ *            or else return HTTP 405").
+ *   DELETE — session termination. We are **stateless** (no session store,
+ *            no Mcp-Session-Id issued) → 405 + Allow (spec MAY for servers
+ *            without session management).
+ *   Origin — spec MUST validate when present (DNS rebinding). Machine
+ *            clients (CLI/desktop) send none → allowed; browser origin must
+ *            match this request's Host (same-origin).
+ *   Accept — clients MUST list application/json + text/event-stream; we
+ *            require json to be acceptable, else 406.
+ *   MCP-Protocol-Version header — when present must be supported, else 400.
+ *   Batching — REMOVED in 2025-03-10. Arrays (including []) → Invalid
+ *            Request. (r1's custom batch handling was rejected; spec wins.)
+ *
+ * Auth model (deliberate, unchanged placement):
+ *   - The route lives INSIDE the authenticated /api/v1 namespace. No new
+ *     PUBLIC_ROUTES entry — a stranger cannot reach it unauthenticated.
+ *   - CSRF middleware already skips x-api-key / Bearer requests
+ *     (src/security/csrf-protection.js ~line 216) — machine calls pass.
+ *   - Credential TYPE preservation (judge r1 blocker): the downstream
+ *     loopback call carries the SAME credential that authenticated this
+ *     request (req.auth.type is set to 'apikey' | 'jwt' | 'session' by
+ *     src/utilities/middleware.js:549-586 — verified, not guessed):
+ *       apikey → x-api-key with the caller's dk_ key
+ *       jwt    → Authorization: Bearer <caller's JWT>
+ *       session/none → NO machine credential: tools/call and resources/list
+ *         deny with JSON-RPC -32001 (a dashboard cookie is not a delegable
+ *         machine credential; mint a real key in the modal).
+ *     Downstream per-route scope checks apply identically for both kinds;
+ *     a read-only key cannot deploy.
+ *   - JSON-RPC 2.0 structural validation (validateJsonRpc): jsonrpc must
+ *     be '2.0', method a non-empty string, params object-or-omitted, id
+ *     string|number|null when present → else -32600 Invalid Request.
+ *     tools/call without params.name string → -32602 Invalid params.

+ * mode and regularity are fstat'ed from that descriptor, and the bytes are
+ * read from the SAME descriptor. There is no stat-path-then-reopen window

+ *
+ * SECURITY CONTRACT (violation => stderr FATAL + exit 3):
+ *   - path is a regular file, not a symlink, not a directory/special file
+ *   - mode grants neither group nor other access (mode & 0o077 === 0) and
+ *     carries no setuid/setgid/sticky bits (mode & 0o7000 === 0)
+ *   - ownership matches the reading identity: under euid 0 (the only

+ *     equal the euid — you cannot consume another identity's file.
+ *   - MISSING file => exit 0, silent: zero overrides is the normal customer

+ * boundary is cryptographic: a LIFETIME code must HMAC-verify against the
+ * signing secret (.license-secret), which exists ONLY on the creator's
+ * machines. Shipped customer installs carry .license-secret-hash (keyed
+ * digest) which cannot forge or verify an offline lifetime code, and the
+ * online license server never issues lifetime codes to customers. A
+ * customer who creates their own root-owned operator.env flips a flag that
+ * enables a code they can neither forge nor receive. This file therefore
+ * adds no attack surface to the lifetime tier; it removes the need for the
+ * creator to hardcode host exceptions into start.sh.
+ *
+ * TRANSLATION (content is pure data — never sourced/evaled/executed):
+ *   - blank lines and lines whose first non-space char is '#' are skipped
+ *   - KEY must match ^[A-Za-z_][A-Za-z0-9_]* (optional spaces around it)
+ *   - malformed lines: stderr warning, skipped, exit stays 0
+ *   - value = everything after the first '=' verbatim ('#' inside a value
+ *     is DATA); surrounding double quotes stripped; leading spaces trimmed
+ *
+ * Usage: node operator-flags.js <file>
+ * Exit:  0 = ok (zero or more KEY=VALUE lines on stdout)

+"""DashCaddy API surface extractor.
+
+Generates a HIGH-COVERAGE (not guaranteed-complete) declarative inventory
+of the DashCaddy API (Express + Node.js). Writes API-SURFACE.md at the repo
+root. See the Known Limitations section it emits for what can be missed.
+
+What it captures:
+- Literal single-line `router.<method>(...)` and `app.<method>(...)`
+  registrations (multiline/computed/chained/router.route()/app.all() forms
+  may be omitted)
+- Full path (resolved via the maintained mount/composition map in this file)
+- Auth classification (public vs protected) per PUBLIC_ROUTES allowlist
+- Rate-limit bucket inferred from path (GENERAL / STRICT / TOTP)
+- Source file:line for every route
+- Mount-point map (route file → URL prefix)
+- Cross-check against openapi.yaml: which routes are undocumented,
+  which docs are stale
+
+Originally written 2026-07-13 to produce the v1.0 release reference.
+Re-run after any of:
+  - Adding new route files under dashcaddy-api/routes/
+  - Changing apiRouter.use('/prefix', ...) mount order
+  - Updating PUBLIC_ROUTES in src/utilities/middleware.js
+  - Bulk changes to openapi.yaml
+
+Usage:
+    python3 scripts/api-surface-extract.py
+        # auto-detects dashboard root under ~/.openclaw or /opt/dashcaddy
+    python3 scripts/api-surface-extract.py --root /path/to/dashcaddy
+        # explicit repo root
+    python3 scripts/api-surface-extract.py --out /tmp/api-surface.md
+        # custom output path

+// AI Chat Panel — DashCaddy AI Intent Router frontend (DC-163)
+//
+// Fixes over the previous version:
+//  - Response parsing: the API returns a FLAT ok() envelope
+//    ({success:true, intent, response, appId, engine…}); the old code read
+//    data.data (nonexistent) so EVERY reply showed "Sorry, something went
+//    wrong". Now reads the real shape.
+//  - Suggestion chips: old inline onclick used nested double quotes —
+//    invalid JS, chips did nothing. Now data-attributes + listeners.
+//  - Deploy button: window.openAppSelector never existed; now calls
+//    window.openDeployConfigFor(id) added to app-selector.js (opens the
+//    real deploy modal, same flow as clicking the app in the catalog).
+//  - Conversation history (last turns) rides along so the LLM engine can
+//    resolve "yes" / "name it vault" / follow-ups.
+//  - Engine indicator: header shows live status from /ai/capabilities.
+//  - ⚙ Settings: configure the LLM (OpenAI-compatible baseUrl/model/key)
+//    stored server-side in the encrypted credential store; Test button
+//    proves it end-to-end. Keys never come back from the server.
+// All server/model text renders via textContent (no HTML injection).
