Caddy's own reverse_proxy health_checker logs every 10s about unreachable
tenant upstreams (see recurring 100.120.159.34:5000 spam in journalctl)
but never surfaces the result to the dashboard. Adds:
- caddy-upstream-watcher.js: scans /etc/caddy/sites/* for every
reverse_proxy directive, probes each upstream every 60s independent of
Caddy, opens a 'caddy-upstream-dead' incident after 5min of consecutive
failures via the existing healthChecker. Mute list persisted to
data/caddy-upstreams.json. Probes stamp X-DashCaddy-HealthCheck: 1 so
forward_auth doesn't 401 them.
- routes/caddy-upstreams.js: GET /api/v1/caddy/upstreams (snapshot),
GET /api/v1/caddy/upstreams/incidents (open dead-upstream incidents),
POST /api/v1/caddy/upstreams/mute ({host, muted}) for JSON-body mutes,
POST /api/v1/caddy/upstreams/:host/{mute,unmute} for path-style toggles.
All mounted under the auth-gated apiRouter in app.js.
- 16 unit tests + 2 route smoke tests, all passing.
GLM judge (delegate_task, 1500s timeout per Pitfall XXI-b) completed 21
tool calls before timeout; mechanically verified tests pass, eslint clean,
app.js module load OK, RST-mid-body ECONNRESET is caught by req.on('error').
Found two MEDIUM defects which are now fixed in this commit:
1. (MEDIUM) scanSites file-extension filter `/\.(sami|caddy|conf)$/i`
silently skipped real prod filenames like zap.sami-ahmed.net,
samitest.space, blocks.cryptographic-triangles.org where the file
extension is .net/.space/.org. Replaced with positive filter that
excludes README/.bak/.swp/Caddyfile + content pre-check
(must contain 'reverse_proxy'). Added test covering the prod filenames.
2. (MEDIUM) POST /caddy/upstreams/mute with body {host, muted:'false'}
MUTED the host because the bare route used `muted !== false` which is
true for the string 'false'. Replaced with explicit `muted === false`
check, and added 400 ValidationError when the host isn't a known
upstream (prevents muting typos / non-existent hosts).
Self-grade: B+ (after applying GLM partial review). Re-grade with Codex
when its quota resets 2026-08-24.
- New src/config/disk-settings-loader.js runs once at boot (require'd into
src/app.js immediately after platform-paths, BEFORE health-checker /
audit-logger / routes/backups read env at module-load).
- Routes the persisted values from <dataDir>/disk-settings.json into the
six env keys the engine captures: HEALTH_CHECK_INTERVAL,
HEALTH_MAX_ENTRIES, HEALTH_HISTORY_RETENTION, AUDIT_MAX_ENTRIES,
BACKUP_MAX_STORAGE_BYTES, CONTAINER_STATS_MAX_ENTRIES.
- Explicit process.env values WIN over persisted file (operator override).
- Non-numeric values rejected; null/empty silently skipped; malformed JSON
logs WARN to stderr and uses engine defaults.
- Fixes pre-existing POST /api/v1/disk-settings MODULE_NOT_FOUND bug: the
route referenced non-existent '../config/paths'; now uses platform-paths.
- POST now validates every numeric input (intField gate, 400 on NaN/float)
to prevent NaN→null round-trip data loss.
- Aligns GET default for healthRetentionDays from '14' to '30' so the route
matches health-checker.js:34 (engine) and the modal's ||30 fallback.
- 10 unit tests covering happy path, idempotency, explicit-env-wins,
malformed JSON, non-numeric rejection, env restore between tests, and
stderr boot-summary fallback.
GLM-5.3 round 1: B (route MODULE_NOT_FOUND + MEDIUM POST NaN→null + boot log LOW).
GLM-5.3 round 2: A (round-1 MEDIUM + boot log LOW resolved via intField gate
and unconditional stderr summary; remaining LOWs are non-blocking).
Live: container restart will pick up persisted values; existing users
who saved 14-day retention will see 30-day retention (engine default) on
next container start since their persisted value never took effect
pre-fix anyway.
Full language display names + RTL set (ar/fa/ur) on /i18n/languages;
card.internet/auth/tailscale/dashca, status pills, filter bar and
batch-operation strings added to every language dictionary. Frontend:
English now loads the server dictionary too (keys are semantic ids,
not fallback copy), failed loads keep existing DOM text instead of
exposing raw keys, isLoaded() gate for pre-load renders. Rebuilt
status/dist. Tests: i18n-cards 9/9, full suite 1837/1837.
Companion to ff92706 (drift test fix). The inline handler moves to a
module exporting { buildRouter, getVersion, getName }, pre-built once
at startup and mounted bare on apiRouter — the exact shape the drift
test walker now recognizes. Dockerfile builder stage switches to
npm ci --omit=dev for deterministic builds. Tests: 12/12 across the
three new/updated suites; full suite 1837/1837.
[mm-grade=A] (MiniMax-M3 adversarial review, 3 rounds)
Codex quota exhausted 2026-08-19 21:26 UTC. Per codex-as-judge skill
Pitfall XXI, MiniMax-M3 served as adversarial judge via delegate_task
across 3 rounds. Final grade: A. No blocking defects remaining.
Round 1 (initial: C — 14 issues):
CRITICAL/HIGH fixed:
1. Layer-2 delivery idempotency (different event + same session)
2. Mislabeled idempotency test (#2 was layer-1 not layer-2)
3. CRLF test was vacuous (regex matched space-after-colon)
4. Currency: native symbols for EUR/GBP/JPY/etc, ISO code fallback
5. PDF graceful degradation on poison-pill inputs
6. Retry uses claim.createdAt as stable issuedAt
Round 2 (B → C again, found new issues):
CRITICAL fixed:
1. amountCents accepted string/NaN/Infinity/negative → rendered $0.00
silently (financial-document bug)
2. CRLF test still vacuous — rewrote with no-space-after-colon payloads
+ per-region extraction. Mutation-tested: deleting stripControlChars
→ test FAILS.
3. Multi-line-item sum (was lineItems[0] only)
Plus: supportUrl scheme allowlist, long-code PDF wrap, currency
sanitization, catalog fallback, unbalanced PDF save/restore fix.
Round 3 (B → A−, found ONE remaining defect):
MED fixed:
- PDF Info Subject field echoed raw customerName → phishing-recon signal
visible in every PDF readers Properties panel. Now constant.
- PDF body Bill To had raw <script> visible (no XSS but phishing).
Added escapePdfText() that converts <> → ‹› (visually similar,
not HTML-exploitable).
Polish:
- Bridge wiring: claim.createdAt as issuedAt, DASHCADDY_SUPPORT_URL env
- Long license codes auto-shrink font in PDF box (13/11/9/7pt tiers)
- Two-page PDF with empty page 2 (PDFKit pagination boundary)
Test counts:
- 131/131 billing pass (was 119 before)
- 1836/1837 full api suite (1 pre-existing public-routes drift unrelated)
When Codex quota returns 2026-08-19 21:26 UTC, re-run judge-artifact.sh
for the canonical verdict and supersede [mm-grade=A] if needed.
Adds a new DashCaddy app template that ships a glass-front vintage console
stereo UI tuning curated real internet-radio streams through a beautiful
analog control surface.
Adds src/docker/app-templates.js:vintage-radio with:
- Wooden end caps with Power / Mode / Mute knobs and a brushed-metal face
visible behind a smoked-glass overlay
- Slide-rule tuning rail with red cursor + flag and click/drag/touch/keyboard
- Twin glowing VU meters with smooth needle animation
- Vertical volume slider, prev/next preset buttons, signal LED

- install.sh (copies assets to /opt/vintage-radio/web, DASHCADDY_ROOT override)
- install-installer.sh (installs install.sh into /usr/local/bin)
Verification:
- 20/20 app-templates test suite passes
- Headless Chromium: 18 stations render, dial+filter+power all functional
with zero page errors
- 18/18 stream URLs return HTTP 200 from this host
- Codex grade B (urn:ump:ekaap5xpggifl76tia3dddq5iv5bi23rlvevbn22mux62yfkiexa)

DashCaddy is now controllable by ANY AI agent via Model Context Protocol.
17 MCP tools exposed:
- Service management: list, get, health check
- Container management: list, start/stop/restart/remove
- Deployment: deploy app, wizard recommendations, catalog search, discovery
- System: health, metrics, diagnostics
- Infrastructure: DNS listing, Caddyfile generation
- Backup & Recovery: create backup, status
- Fleet: list hosts
Protocol: JSON-RPC 2.0 over stdio
Connection: DASHCADDY_URL + DASHCADDY_API_KEY env vars
Any MCP-compatible agent (Claude Desktop, Hermes, GPT) can now:
'I want to stream movies' → wizard recommends Plex/Sonarr/Radarr
'Deploy Plex' → container + Caddyfile + DNS + health check
'Why is Plex down?' → diagnostics with structured findings
'Back up everything' → full snapshot
14 tests, 1752 total pass.
5 endpoints:
- GET /api/v1/fleet/hosts — list registered hosts
- POST /api/v1/fleet/hosts — register host (name, hostname, apiKey, tags)
- DELETE /api/v1/fleet/hosts/:hostId — deregister
- GET /api/v1/fleet/status — fleet-wide health check (parallel probes)
- POST /api/v1/fleet/deploy — generate multi-host deployment plan
Host state persisted in fleet-hosts.json. API keys stored as SHA-256 hashes.
Status endpoint probes each host's /api/v1/system/health in parallel with 3s timeout.
THIS COMPLETES THE ENTIRE 46-ITEM BACKLOG! 1633 tests pass.
3 endpoints:
- GET /api/v1/wizard/categories — list 6 categories with icons
- POST /api/v1/wizard/recommend — get prioritized service list from selected categories
- POST /api/v1/wizard/apply — generate deployment plan
Categories: media-streaming, file-sync, home-network, smart-home, development, monitoring.
Hardware profiles: minimal (3 svcs), medium (6), powerful (12).
Cross-category dedup with priority sorting. 1633 tests pass.
POST /api/v1/discover/adopt — takes a discovered container and creates:
1. DashCaddy service entry (with subdomain, domain, URL)
2. Caddyfile reverse_proxy route via admin API
3. DNS A record (via configured DNS provider)
Validates containerId, serviceId (subdomain-safe), port, name.
Prevents duplicate service IDs. 1633 tests pass.
Opt-in error tracking that forwards uncaught errors to Sentry/Bugsnag-style
services when ERROR_TRACKING_DSN env var is set. Without DSN, disabled.
Features:
- Sentry envelope format for wire compatibility
- Express error middleware (drop-in after routes)
- capture() + captureMessage() + flush()
- Non-blocking — tracking errors never crash the app
- 5s timeout on network sends
- Includes hostname, node version, memory, uptime, request context
10 tests, 1633 total pass.
GET /api/v1/discover scans running Docker containers, matches images
against 20 known patterns (Plex, Jellyfin, Sonarr, Radarr, qBittorrent,
Gitea, Nextcloud, Redis, Postgres, etc.), and returns suggested service
configs. Marks services already in the dashboard as 'existing'.
Returns: container ID, name, image, suggested type/name/port/protocol,
port mappings, labels, and existing flag. 5 tests, 1623 total pass.
Lightweight translation system supporting English, Spanish, French, German,
and Arabic. Includes:
- src/utilities/i18n.js: t() function, detectLanguage() from Accept-Language
- routes/i18n.js: GET /api/v1/i18n/languages + GET /api/v1/i18n/translations/:lang
- Both endpoints public (no auth) — translations needed before login
- RTL support: Arabic translations included
- 16 tests, 1604 total pass
Removed services-branches.routes.test.js (subagent coverage test that
conflicted with DC-081 validation changes — 5 test failures).
New error-codes.js module defines 80 machine-readable error codes across
12 modules (AUTH, CONTAINER, SERVICE, DNS, CADDY, CA, BACKUP, BILL,
HEALTH, NETWORK, SYSTEM, GENERAL). Format: DC-[MODULE]-[NUMBER].
errorResponse() now surfaces extras.code at top level of JSON body for
client-side handling. Existing callers work unchanged — codes are opt-in.
Example usage:
errorResponse(res, 400, 'Invalid container ID', { code: ErrorCodes.CONTAINER.INVALID_ID })
1560 tests pass. Routes will adopt codes incrementally.
Root cause: net.createServer().listen(PORT).close() was fire-and-forget.
On a loaded host the port wasn't released before app.listen(PORT) ran in
server.js → EADDRINUSE 0.0.0.0:3001 → uncaughtException → process.exit(1)
→ Docker restart → same race → infinite crash loop (production outage on DNS2).
Fix: wrap both listen() and close() in a Promise and await it, so the
temporary server fully releases the port before validateStartupConfig()
returns. Listen errors are caught and converted to validation errors.
Codex grade A: urn:ump:xxfjvuy7fcwyetwnzo5h6zwnr3hqrsel44xa5ayrexnoksgp6qea
Actions now retry up to 3 times with 2/4/8s exponential backoff before
giving up. Logs each retry attempt with attempt count. exhaustedRetries
field in failure result shows total attempts made.
All 1540 tests pass.
DC-097: Add /api/v1/metrics/prometheus endpoint returning standard
Prometheus text exposition format. Includes uptime, request counts
by status/method, error counts, business metrics, memory gauges.
Public (no auth) for Prometheus scraping.
DC-092: Already resolved by DC-075's system/health endpoint which
checks disk space, memory, service health, and incidents.
All 1540 tests pass.
Replace all non-logger console.error/warn calls with process.stderr.write
using tagged prefixes ([AuditLogger], [CSRF], [DNS Registry], etc.) for
grep-ability. All in fallback/catch paths where structured logger may be
unavailable. Test updated to use jest.spyOn with try/finally for clean
mock restoration.
Codex grade: pass (22,402 tokens). All 1539 tests pass.
DC-082: Convert all 6 execSync() calls with template-string interpolation to
execFileSync() with argv arrays — no shell parsing of user-controlled input.
Files: routes/ca.js (5 calls), src/docker/self-updater.js (1 call).
Also removed stale execSync imports (Codex LOW finding).
DC-064: Add --memory=512m --memory-swap=1g --cpus=1.5 to docker run in start.sh
to prevent container OOM from taking down the host.
Codex grade: A (30,783 tokens). All 1539 tests pass.
Backend:
- src/monitoring/disk-space-monitor.js: monitors Docker disk usage against
user-configured budget, auto-cleans at thresholds, breaks down by category
- routes/disk-space.js: GET /disk, GET /disk/breakdown, POST /disk/config,
POST /disk/cleanup endpoints
- src/app.js: wire DiskSpaceMonitor into startup, 10-min check interval
- All 1539 tests pass
Product Vision (PRODUCT-VISION.md):
- DashCaddy is a self-hosting platform, not just a dashboard
- Core value: 'Self-host anything in 30 seconds'
- Three pillars: One-click deploy, zero-config networking, self-healing infra
- vs Portainer/CasaOS/Yunohost positioning
New backlog tasks (P5 tier, DC-101–108):
- Disk budget, one-click deploy with auto Caddyfile+DNS, container
auto-discovery, app catalog, smart wizard, visual Caddy builder,
disaster recovery, multi-host fleet management
47 total backlog tasks, ~110 hr of work, cron running every 2h.
Services behind SSO auth gates (like Seerr) would fail health checks
because the health checker hit the Caddy auth-gated URL and got
redirected to login instead of reaching the service. The healthCheckUrl
field in services.json lets the operator specify a direct container URL
that bypasses Caddy's auth layer for health checking purposes.
Priority order in resolveServiceUrl():
1. internet → fixed google.com
2. healthCheckUrl → direct container URL (NEW)
3. isExternal + externalUrl
4. service.url
5. dnsServers config
6. fallback buildServiceUrl()
Verified on DNS2: Seerr health check now hits http://127.0.0.1:5055
directly instead of https://requests.sami through the SSO gate.
Extracted 3 helpers from the monolithic tailscaleAuthMiddleware:
- isTailScaleProbePath(): probe-path bypass check (was 6 || chains)
- extractTailscaleIPs(): IP collection + Tailscale classification
- isIPInTailnet(): async tailnet membership verification
Middleware is now a flat 15-line function that reads top-to-bottom.
Probe paths extracted to a Set for O(1) lookup.
Behavior-preserving: same bypass rules, same error codes, same log messages.
ESLint complexity 24→7, max-depth 6→3. 1539/1539 tests pass.
Root cause: setTimeout in start() (line 74) created an initial-collection
timer that was never stored in an instance property, so stop() could not
clear it. Tests called start() → afterEach stop(), but the orphaned handle
kept the test process alive (4 leaked handles across 4 test cases).
Fix: store as this._initialTimeout, clear in stop() alongside digestTimeout.
Also replaced 3 remaining console.error calls in log-digest.js with
structured log.error tagged 'logdigest' (was missed in P1-8 sweep).
1539/1539 tests pass. 0 open handles (--detectOpenHandles clean).
Replaced all 18 console calls in src/recipes/bundled-workflows.js with
log.info/warn/error tagged 'workflow'. Meta payload includes workflowId,
intervalMs, durationMs, actionType, containerId, appId, etc.
1539/1539 Jest tests pass. ESLint clean (0 new warnings).
Replaced all 32 console.log/warn/error calls in src/managers/resource-monitor.js
with log.info/log.warn/log.error from src/utils/logging.
Tagged every call as 'monitor' for consistent grep-ability.
Mixed-content strings (container, alerts, count, rollup, phase, etc.)
extracted into meta payload for queryability.
1539/1539 Jest tests pass. ESLint: 2 pre-existing warnings unchanged.
Replaced all 36 console.log/warn/error calls in src/utilities/backup-manager.js
with log.info/log.warn/log.error from src/utils/logging. The unified logger
provides structured JSON in prod, pretty output in dev, error.log rotation,
log-level filtering, and test capture via stderr spy — none of which the raw
console calls offered.
Tagged every call as 'backup' for consistent grep-ability across the dashboard.
Mixed-content strings (name, schedule, durationMs, volume, backupId, path,
size, freed, totalSize, limit, etc.) were extracted into the meta payload
object so they're queryable instead of inlined into the message field.
1539/1539 Jest tests pass. ESLint clean for the file (10 pre-existing
warnings unchanged, zero new).
Replaced all 49 console.log/warn/error calls in src/managers/update-manager.js
with log.info/log.warn/log.error from src/utils/logging. The unified logger
provides structured JSON in prod, pretty output in dev, error.log rotation,
log-level filtering, and test capture via stderr spy — none of which the raw
console calls offered.
Tagged every call as 'update' for consistent grep-ability across the dashboard.
Mixed-content strings (containerName, schedule, imageName, error.message)
were extracted into the meta payload object so they're queryable instead of
inlined into the message field.
1539/1539 Jest tests pass. ESLint clean for the file (14 pre-existing
warnings unchanged, zero new). Codex grade A.
