Merge dc/DC-087-test-mirrors-fetcht: hermetic caddy-admin test mirrors + raw-fetch guard [glm-grade=B]

Two mirrored health-handler test suites (health-endpoints, health-probe-aliases)
probed the Caddy admin API with raw Origin-less native fetch. On the prod host
the adversarial cron runs the full jest suite every 30 min against a live Caddy
admin with enforce_origin: 12 journal 403 lines per run (~700/day of
'client is not allowed to access from origin' spam) while tests stayed green.

- Mirrors now call fetchT (byte-identical to src/app.js:930 probe) with fetchT
  jest.spyOn-mocked at buildApp scope; caddyOk-configurable in both suites
- New guard test in utils-http-caddy-admin-origin.test.js: any __tests__ file
  pairing a raw await-fetch with a Caddy-admin token (:2019|adminUrl|
  CADDY_ADMIN) fails the suite — file-level pairing catches the historical
  cross-line drift shape a call-window regex missed
- DC-087-ALLOW-RAW-FETCH comment escape hatch (raw-text marker, guard file
  never self-exempts, skips logged to jest output)

Judge: GLM-5.3 cold read via delegate_task deleg_4d384dea (round 1 C -> round 2
B, zero blockers, polish folded). Verdict URN: urn:ump:azrv2xp72koiwi5r4yb6ureu4aqqloqq64sgmftsajh6ci2mzj2q
Mutation probes: historical drift reintroduction -> guard red; hatch marker ->
skipped+logged; restore -> 33/33. Full suite 2603/2603.

+# DashCaddy AI-Native Vision
+
+## The Vision
+DashCaddy should be inherently optimized for AI agents to control it.
+Users should be able to self-host anything using natural language.
+
+## Core Principles
+1. **AI as first-class citizen** — not a bolt-on chatbot, but where the API itself is designed for AI consumption
+2. **Natural language → deployment** — "host a Plex server" → running container + reverse proxy + DNS + health check
+3. **Agent-friendly API** — structured responses, semantic error codes, state machines, idempotent operations
+4. **MCP-native** — DashCaddy should expose itself as an MCP server so any AI agent can control it
+
+## Architecture Layers
+
+### Layer 1: Natural Language Intent Router (NEW)
+`POST /api/v1/ai/intent` — Takes natural language, returns structured action plan
+- "I want to stream movies" → { category: media-streaming, recommended: [plex, sonarr, radarr] }
+- "Set up a password manager" → { category: file-sync, recommended: [vaultwarden] }
+- "Block ads on my network" → { category: home-network, recommended: [adguard] }
+- "Why is Plex down?" → diagnostics query → { action: health-check, service: plex }
+
+### Layer 2: MCP Server (NEW)
+Expose DashCaddy as a Model Context Protocol server so ANY AI agent (Claude, GPT, Gemini, Hermes) can:
+- List services, containers, health status
+- Deploy/stop/restart apps
+- Manage DNS records and Caddyfile routes
+- Run diagnostics and get structured results
+- Create backups and restore
+
+### Layer 3: Structured Action API (EXISTING — needs enhancement)
+366 existing routes already cover the CRUD surface. Enhancement needed:
+- Consistent response envelopes (already have `ok()` / `errorResponse()`)
+- All error responses include machine-readable codes (DC-086 done — 80 codes)
+- Idempotency keys for mutating operations
+- Operation receipts (UUID + status tracking)
+
+### Layer 4: Semantic Service Catalog (EXISTING — DC-104)
+76 templates with categories, auto-categorization, search.
+Enhancement: Add intent tags ("movie streaming", "password manager", "ad blocking")
+
+### Layer 5: Diagnostic Engine (NEW)
+`POST /api/v1/ai/diagnose` — Structured troubleshooting
+- "Why is X slow?" → checks: CPU, memory, network, disk I/O, container logs
+- Returns structured findings with severity + suggested fix
+- Can auto-apply fixes with user approval
+
+### Layer 6: Deployment Orchestrator (PARTIAL — DC-103 + wizard)
+"Deploy Plex" → full automation chain:
+1. Pull image
+2. Create container with optimal config
+3. Generate Caddyfile route (DC-106)
+4. Create DNS record
+5. Add to services list
+6. Start health monitoring
+7. Configure notifications
+8. Return ready-to-use URL

 - **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-086: Service-status flicker fix — asymmetric hysteresis on the badge
+- **status:** in-progress
+- **owner:** hermes
+- **details:** Dashboard service badges perpetually flip between green and red for "a few seconds at a time, never stable" (Sami's report, 2026-08-20). Root cause: `src/monitoring/health-checker.js` `recordStatus()` emits `'status-check'` on EVERY probe (every 30s), and `src/websocket/dashboard-ws.js` forwards every probe as `'status-change'` to the browser with no diff. The frontend `live-events.js` then unconditionally calls `setBadge()` — which resets the icon + pill text on every event. A single transient 5xx (Caddy reload, container CPU steal, mid-flight TLS handshake, container restart during probe) flips the badge red and the next green probe flips it back. Fix: add asymmetric hysteresis in `_computeDisplayedStatus(serviceId, rawStatus)` — going DOWN requires 2 consecutive "down" probes (default `HEALTH_DOWN_THRESHOLD=2`), going UP requires only 1 (default `HEALTH_UP_THRESHOLD=1`). History + `consecutiveFailures` still record raw probe results (operators want full fidelity for postmortems); only the dashboard broadcast is filtered. `getCurrentStatus()` now returns the displayed status so a page reload shows the same badge as the live SSE stream. Both thresholds are env-var configurable so operators can tune. New tests in `__tests__/health-checker-hysteresis.test.js` cover: first probe emits; second probe same-status does NOT re-emit; one-down-then-up keeps green; two-down flips to red; one-up after down flips back to green; `getCurrentStatus` returns displayed not raw. Effort: ~30 min. Risk: low — pure behavior filter, no schema breaks, all 63 existing health-checker tests must stay green.
+- **impact:** Operators stop seeing perpetual red/green flicker on healthy services. Real outages still get flagged (2 consecutive 30s probes = ~60s before badge flips red, which is still faster than a human notices). Background probe history is unchanged so postmortem analysis still works.
+- **prerequisite:** None.
+- **result:** _pending — ship + codex round_
+
+### DC-085: Link-first invite — Discord-style "share it however you want"
+- **status:** in-progress
+- **owner:** hermes
+- **details:** Today `POST /api/v1/auth/admin/invites` defaults to sending the invite link via SMTP; if SMTP is not configured it spams the server console with `[DC-048-DEV-INVITE-LINK]` log lines. Sami wants Discord-style: the link is always returned in the response, and email is an opt-in checkbox. Operators should be free to copy the link and share it via iMessage / SMS / WhatsApp / Telegram / Signal / Discord / paste-in-email — whatever fits. (1) Flip default `sendEmail !== false` to `sendEmail === true` in `routes/auth/admin.js` so omitting the field means "no email, just hand me the link." (2) Stop logging the raw invite URL to error.log when SMTP is unconfigured — that path was only useful when there was no UI way to grab the link; now there is. (3) Add a `shareText` field to the response: `"Join my DashCaddy as <role> — <acceptUrl> — expires in Nh."` for one-tap paste into any messenger. (4) Frontend: `status/js/admin.js` `_renderInviteForm` flips the "Send email" checkbox default to **unchecked**, updates `_renderIssuedInviteBanner` to show both the raw link AND the shareText (with its own copy button + `navigator.share()` native share-sheet button where available). (5) New tests in `__tests__/admin-invites.test.js` covering: default sendEmail=false (no SMTP send attempted, no console log); `sendEmail: true` triggers SMTP send; `shareText` is present and well-formed; `acceptUrl` is always returned; expired sendEmail path doesn't leak token to logs. Effort: ~1 hr. Risk: low — pure behavior flip + UI additive change.
+- **impact:** Closes the friction between "host wants to add a friend" and "host has to configure SMTP first." Mirrors Discord/Slack/Linear invite flows where the link IS the deliverable. No new tier changes, no schema breaks.
+- **prerequisite:** DC-048 (invite store + admin route), DC-052 (Pro gate stays).
+- **result:** _pending — ship + codex round_

+### DC-084: Remove redundant active Caddy health check from `arch.sami` site — eliminate 6 syslog spam lines/min
+- **status:** done
+- **owner:** hermes
+- **details:** `/etc/caddy/sites/arch.sami` had an active Caddy health check (`health_uri /api/stats health_interval 10s`) probing `100.120.159.34:5000` every 10 seconds. The upstream Arch Linux server `100.120.159.34` has been permanently unreachable (100% packet loss on ping, ports 5000 + 8080 both time out). Result: 6 `level:info HTTP request failed` journal lines per minute, 360/hour, 8640/day — pure noise, no dashboard value, no incident resolution. The `src/monitoring/caddy-upstream-watcher.js` (the same module whose source comments explicitly call out this exact spam as "the noisy spam the dashboard currently sees for `100.120.159.34:5000`") ALREADY provides equivalent monitoring: 60s probe cadence (6x less frequent), 5-minute confirmation window before opening incidents, mute toggle, deduped snapshot, incident integration with the health-checker. The active Caddy check is redundant. Fix: edit `/etc/caddy/sites/arch.sami` to remove the `health_uri / health_interval` block, leaving only `reverse_proxy 100.120.159.34:5000`. Apply via `caddy-apply` (validates+reloads+commits atomically). Backup `.bak-DC-084-pre` created pre-edit; deleted after `caddy-apply` succeeded because the `.bak` file was being picked up by Caddy's `import sites/*` and causing an "ambiguous site definition" validation error.
+- **impact:** Eliminates 100% of recurring caddy journal spam from the dead Arch upstream. The dashboard's `caddy-upstream-watcher.js` continues to monitor the dead upstream correctly (now at `consecutiveFailures: 1905+`, `lastSuccessAt: null`, `status: down`, `dead: true`) — operators see the dead upstream in the dashboard, just without the journal noise. Future Caddyfile authors who add an active health check to a `*.sami` site will be unaware that they should not (since the dashboard handles monitoring), so a follow-up could add a CLAUDE.md note or a Caddyfile lint warning. Out of scope for this tick.
+- **prerequisite:** None. `caddy-upstream-watcher.js` already provides equivalent monitoring.
+- **result:** Shipped GLM-pending (Codex quota dead). Before/after on DNS2 (`journalctl -u caddy --since "5 minutes ago" | grep health_checker.active | wc -l`): **before = ~30 entries / 5min** (active probe every 10s, all failing); **after = 0 entries / 5min**. Live-verified: `caddy validate` succeeded (after removing `.bak` file that caused `ambiguous site definition`), Caddy reloaded via `caddy-apply`, route `arch.sami → 100.120.159.34:5000` still active in admin API (verified via `curl http://localhost:2019/config/apps/http/servers/srv0/routes` — `health_uri: None, health_interval: None` confirms the block is gone). Container `dashcaddy-api Up About an hour (healthy)` (no restart needed — only Caddyfile changed, not container). Live HTTP smoke all green: `https://status.sami=200`, `https://dashcaddy.net=200`, `https://ca.sami=200`, `https://status.sami/api/health=401` (auth-gated, expected). Watcher state for `100.120.159.34:5000`: `consecutiveFailures: 1905`, `lastError: "probe timeout"`, `status: down`, `dead: true` — correctly tracked in `/opt/dashcaddy/dashcaddy-api/data/caddy-upstreams.json`. Backup deleted (would have caused site-definition ambiguity on next Caddy reload). Git: change lives only in DNS2's `/etc/caddy/sites/arch.sami` (the `/etc/caddy` git repo `.gitignore` excludes `sites/` per design — only the main `Caddyfile` is tracked). The dashcaddy source repo (`/root/dashcaddy`) carries only this BACKLOG.md documentation update on branch `dc/DC-084-arch-sami-caddy-healthcheck-removal`.
+- **Tests:** No source code change; existing `__tests__/caddy-upstream-watcher.test.js` 26/26 pass (baseline preserved). 2465/2465 repo tests pass (4 pre-existing billing test suites fail with `Cannot find module pdfkit` — unrelated to this change).

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

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

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

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

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

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

+ * DC-081: log-insights dispose path + keepDays input validation hardening.
+ *
+ * Two coupled bugs surfaced in the 2026-08-19 sweep:
+ *
+ *  1. log-insights.js hardcoded the audit-log.json + security-events.jsonl
+ *     paths to `/opt/dashcaddy/dashcaddy-api/data/...`, which does NOT
+ *     exist inside the production container — files live at
+ *     `/app/data/...` (mounted via the existing data bind). The dispose
+ *     endpoint silently no-op'd: `fs.readFile('/opt/.../audit-log.json')`
+ *     hit the `.catch` arm → `auditData = []` → wrote an empty file back.
+ *
+ *  2. `parseInt(req.body.keepDays) || 30` accepted negative numbers. A
+ *     keepDays of -1000 produces a cutoff +3 years in the future and
+ *     deletes 100% of the audit log. Operators should not be able to wipe
+ *     forensic context by clicking through with a typo.
+ *
+ * DC-081 fix:
+ *   - `_resolvePaths()` returns `{ auditPath, secPath }` from
+ *     `process.env.AUDIT_LOG_FILE || path.join(platformPaths.dataDir, 'audit-log.json')`
+ *     — same canonical resolution as the audit-logger module.
+ *   - `_validateKeepDays(raw)` rejects out-of-range / wrong-type input
+ *     with an Error BEFORE any file IO.
+ *   - POST /log-insights/dispose now requires `{ keepDays: integer 1..3650, confirm: true }`.
+ *     The pre-confirm preview is read-only.
+ *
+ * Verified live on DNS2 2026-08-19: `/app/data/audit-log.json` (318 KB)
+ * and `/app/data/security-events.jsonl` (15 MB) both exist; the old
+ * `/opt/dashcaddy/dashcaddy-api/data/...` paths are ENOENT in the container.

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

+/**
+ * DC-083 -- Public share endpoint input hardening.
+ *
+ * The two CSRF-exempt public endpoints (POST /share/:token/subscribe +
+ * POST /share/:token/redeem-tailscale) accept untrusted body fields. The
+ * pre-fix code had three coupled bugs:
+ *
+ *   1. `email.includes('@')` accepted `@`, `a@`, `<script>@x.c`, and 10MB
+ *      strings as "valid email" -- and the field was never even used after
+ *      validation (the subscribe endpoint discarded it).
+ *   2. `typeof deviceId === 'string'` accepted arbitrary strings of any
+ *      length, including CR/LF/NUL -- which fed straight into the Tailscale
+ *      auth-key description string and the on-disk shares.json.
+ *   3. No rate-limit; the general limiter (1000/15min) was too generous for
+ *      unauthenticated state-mutating endpoints.
+ *
+ * Fix: charset/length/control-char-bounded validators at the route layer
+ * AND at the store layer (defense-in-depth), plus a dedicated
+ * SHARE_PUBLIC rate-limit (30/15min) on the public endpoints.
+ *
+ * Coverage:
+ *   - subscribe email: rejects bare @, missing TLD, oversized, CR/LF, shell
+ *     metachars, control chars; accepts normal addresses; accepts OMITTED
+ *     email (backwards-compatible with the original behavior).
+ *   - subscribe email propagates to share-store subscriberEmails (capped 8).
+ *   - redeem-tailscale deviceId: rejects CR/LF/NUL, oversized, empty,
+ *     spaces, brackets, quotes; accepts Tailscale-style base64url+hphens;
+ *     accepts OMITTED deviceId (treated as 'unknown').
+ *   - Sanitized usedBy is what flows into the on-disk shares.json.
+ *   - Rate-limit fires after the configured budget per IP.
+ *   - Store-level defense: bypassing the route (direct store call) still
+ *     rejects invalid inputs.

- * DC-106: Reverse Proxy Visual Builder — pure-function unit tests.
- *
- * These tests cover the deterministic, DOM-free surface of the builder:
- *   - state → POST /generate payload mapping (buildPayload)
- *   - template application (applyTemplate hydrates state from a template config)
- *
- * DOM-bound behavior (event handlers, renderHeadersList, copy/validate
- * buttons) is exercised via the headless-browser smoke test
- * `caddy-builder.browser.smoke.test.js` which uses the running dev server.
- * That test is in the `__tests__/integration/` directory and is run on
- * demand; the unit test below has zero jsdom dependency so it runs on
- * every CI tick.
- *
- * The module under test uses an IIFE; we extract the pure helpers via a
- * re-loadable harness that exposes them on globalThis without requiring
- * DOM globals.

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

+ * Caddy admin API CSRF Origin-header tests — DC-051
+ *
+ * Verifies:
+ *   - _httpFetch (fetchT's :2019 raw http branch) injects `Origin: http://<host>:<port>`
+ *     for any Caddy admin URL, satisfying Caddy's `enforce_origin` CSRF check
+ *     that activates on non-loopback admin binds (e.g. `admin 0.0.0.0:2019`).
+ *   - Caller-provided Origin via opts.headers WINS over the auto-injected
+ *     default (so future proxies / tests can override).
+ *   - fetchT routes :2019 URLs through _httpFetch (raw http.request) and
+ *     leaves HTTPS URLs on Node's undici fetch (for self-signed cert support).
+ *   - The /config/apps/http/servers/srv0/listen health probe that the readiness
+ *     handler emits against http://localhost:2019 includes the Origin header.
+ *
+ * Regression for the live 403 spam observed on DNS2 (Caddy log:
+ *   `{"error":"client is not allowed to access from origin ''","status_code":403}`
+ *   from User-Agent:node + Sec-Fetch-Mode:cors at remote_port 5xxxx, repeated
+ *   every ~10s while the readiness workflow probes Caddy admin). The fix is
+ *   the Origin header injection here + the `origins` directive in the
+ *   Caddyfile's admin block on DNS2 — both are required for Caddy's CSRF
+ *   check to accept same-origin admin calls.

+ *
+ * Bug fixed: writeErrorLog previously emitted `error.message` alone.
+ * AggregateError's `.message` is "" by spec, so a real aggregate (e.g.
+ * `await Promise.any([fetch(...), fetch(...)])` or a multi-A DNS lookup
+ * that times out) ended up in error.log as a single empty line:
+ *
+ *   [2026-08-18T06:49:03.345Z] [ERR] update:
+ *   context: {"imageName":"ipfs/kubo:latest"}
+ *
+ * Operators couldn't tell why the check failed. This file asserts the
+ * fixed behavior:
+ *
+ *  - AggregateError → emits a diagnostic block listing each sub-error's
+ *    .code/.message.
+ *  - Regular Error → no spurious diagnostic block.
+ *  - Plain Error with `.code` (e.g. EPIPE) → head now shows
+ *    `Error [EPIPE]: write EPIPE` (regression: `code` used to be dropped).
+ *  - Error wrapping another Error via `.cause` → lists the cause.
+ *  - AggregateError with mixed sub-errors (some Aggregate, some plain) →
+ *    recurses correctly without losing any message.
+ *  - Empty error.message is replaced with the error name so a bare
+ *    AggregateError still renders something readable.
+ *
+ * log.error signature on this codebase: error(ctx, err, req?, extra?)
+ * where extra is the JSON tail (and req is the Express req if any).

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

+ * rejected unknown hosts (with a "not a known upstream" 400). The
+ * path-style `/:host/mute` and `/:host/unmute` endpoints skipped that
+ * check entirely, so an authenticated operator could POST
+ * `/caddy/upstreams/phantom.test:12345/mute` and the watcher would

+ * restarts, pollutes the snapshot view (the muted Set is iterated in
+ * places like the dashboard's "muted upstreams" badge), and would
+ * silently disable any future probe that happened to resolve to the
+ * same string.
+ *
+ * Post-fix, every mute path runs through this helper so:
+ *   (1) host format is well-formed (rejects injection / `:` / `?` / etc.)
+ *   (2) host is in `caddyUpstreamWatcher.upstreams` (the live registry
+ *       populated by `scanSites()` reading every `reverse_proxy` from
+ *       /etc/caddy/sites/*. A phantom host cannot reach setMuted.)
+ *   (3) the muted Set never holds entries the scanner doesn't know.

+ * @param {string} host raw host string from the request

+ *     paths now use the same canonical resolution as the audit-logger
+ *     itself: `process.env.AUDIT_LOG_FILE || path.join(platformPaths.dataDir, 'audit-log.json')`.
+ *   - keepDays was unbounded — `parseInt(req.body.keepDays) || 30` accepted
+ *     negative numbers (e.g. -1000 → cutoff = +3 years in the future,
+ *     deleting 100% of forensic context) and non-integers (Infinity,
+ *     floats). Now validated to an integer in [1, 3650] (1 day .. 10 years)
+ *     before any file read.
+ *   - confirm gate added: must send { confirm: true, keepDays: N } — the
+ *     preview pass is read-only, the confirm pass writes. Matches the
+ *     audit-logs/DELETE confirm=CLEAR pattern.
+ *   - The dispose handler now uses a single shared `_resolvePaths()` helper
+ *     to keep GET and POST in lockstep (and so a future path-config change
+ *     touches one site, not four).
+ *
+ * Pre-DC-081 verification: from inside the running container, both
+ * `/app/data/audit-log.json` (318 KB) and `/app/data/security-events.jsonl`
+ * (15 MB) exist, but the old hardcoded `/opt/dashcaddy/dashcaddy-api/data/...`

+   *       OpenClaw container to push arbitrarily large payloads (DoS,

+   *       `res.set(proxyRes.headers)` copies Connection, Keep-Alive,
+   *       Transfer-Encoding, Upgrade, Proxy-Authenticate, Proxy-Authorization,
+   *       TE, Trailers, Set-Cookie, Content-Encoding, Content-Length, and
+   *       Server. Per RFC 7230 §6.1 the first 8 must NEVER be forwarded;
+   *       Set-Cookie can poison the browser session; Content-Encoding
+   *       and Content-Length mismatches confuse downstream caches/clients.
+   *   (c) `proxyRes.statusCode` treated as a valid HTTP status without
+   *       validation — a broken upstream could send `0` or a string, which
+   *       res.status() would either accept (silent corruption) or throw
+   *       RangeError [ERR_HTTP_INVALID_STATUS_CODE] (Express default
+   *       error handler returns HTML).
+   *   (d) `path` taken from req.params[0] without validation — an attacker
+   *       could pass URL-encoded slashes / `?` / `#` chars / absolute URLs
+   *       to redirect the proxy elsewhere on localhost.
+   *
+   * The five fixes below close (a)-(d) without changing the on-the-wire
