BACKLOG: mark DC-005 fully done + document post-merge health-checker path fix

After DC-005 refactor moved health-checker.js into src/monitoring/, the
require path was never updated. Tests in __tests__/health-checker.test.js
failed with 'Cannot find module' → 59 cascading test failures in the
health-checker suite.

Path: src/monitoring/health-checker.js → 'require(./platform-paths)'
Fix:  'require(../../platform-paths)'

Verified: 921/922 tests passing (one known async-timing flake in
logging.test.js 'writes entry to ERROR_LOG_FILE with context').

+## P0 — Must Fix (blocks public release)
+
+### DC-001: Fix 4 failing tests in services.routes.test.js
+- **status:** done
+- **owner:** hermes
+- **details:** Credential storage tests failing since before v1.13.4. Run `cd dashcaddy-api && npx jest __tests__/routes/services.routes.test.js` to see failures. Fix the root cause, not the test.
+- **result:** Root cause: routes used `/:serviceId/credentials` (missing `/services/` segment). All 3 credential routes (POST/DELETE/GET) in `routes/services.js` had the wrong path. Fixed to `/services/:serviceId/credentials` — matches the URL pattern used by the live frontend and all 759 tests pass.
+
+### DC-011: Fix DC-001 regression reintroduced by src/ refactor (4 failing tests)
+- **status:** done
+- **owner:** hermes
+- **details:** The module-flattening refactor (DC-005) force-pushed to `main` dropped the DC-001 route-prefix fix. `routes/services.js` again defined `/:serviceId/credentials` (POST/DELETE/GET) instead of `/services/:serviceId/credentials`, so `/api/services/:id/credentials` returned 404 and 4 tests in `services.routes.test.js` failed. Baseline: `npx jest` → 4 failed, 746 passed.
+- **result:** Re-applied the `/services/` prefix on all 3 credential routes (matches every other route in the file). Also fixed a latent `ReferenceError`: those same validation branches called `ctx.errorResponse()` but `ctx` is never defined in this module (the factory destructures deps); replaced with the imported `errorResponse` helper so invalid serviceIds now return a clean 400 instead of a 500 crash. Result: 750/750 tests pass (4 failed → 0), zero new ESLint warnings. NOTE: caught a botched local state on entry — origin/main had been force-pushed with a divergent history that dropped BACKLOG.md and the DC-001 fix; reset local to canonical origin/main (old HEAD preserved under tag `backup-pre-origin-reset`) and restored BACKLOG.md.
+
+### DC-002: Sync VERSION file
+- **status:** done
+- **owner:** hermes
+- **details:** `/root/dashcaddy/VERSION` says `1.13.0` but `package.json` says `1.13.4`. VERSION file should always match package.json. Add a pre-commit or post-version bump hook to keep them in sync.
+- **result:** Fixed root VERSION to 1.13.4. Updated `scripts/release.sh` to write both `dashcaddy-api/package.json` AND root `VERSION` on every release — also stages VERSION in the release commit. No more drift.
+
+### DC-003: Remove stale test/debug files from repo root
+- **status:** done
+- **owner:** hermes
+- **details:** `comprehensive-test.js` and `test-security-fixes.js` are ad-hoc test scripts, not Jest tests. They clutter the repo root. Remove them or convert to proper Jest tests under `__tests__/`.
+- **result:** Moved both files to `dashcaddy-api/scripts/legacy/` (preserved, not deleted — they are 875 lines of security test coverage that may be useful as a manual smoke test). Zero references to them in code/docs — safe to move. All 759 Jest tests still pass.
+
+---
+
+## P1 — Code Quality
+
+### DC-004: Fix 19 ESLint warnings
+- **status:** done
+- **owner:** hermes
+- **details:** Run `cd dashcaddy-api && npx eslint src/ --format compact`. Most are unused vars and nested ternaries in `src/utils/logging.js`. Fix all, target zero warnings.
+- **result:** Reached zero ESLint warnings across `src/`. Most of the original 19 were cleared by the DC-005 refactor and logging cleanup; the final 3 were in `src/app.js`: (1) `require-await` on `resyncHealthChecker` — dropped the now-pointless `async` keyword since it only forwards a promise (callers already use `.catch()`); (2)+(3) two `max-depth` violations in the `/api/v1/network/ips` handler — extracted the interface-enumeration logic into a `detectInterfaceIps()` helper, keeping the route handler flat. `npx eslint src/` now reports 0 problems; 750/750 Jest tests still pass.
+
+### DC-005: Organize top-level modules into src/
+- **status:** done (merged to main 2026-06-25)
+- **owner:** krystie
+- **details:** 40+ JS files at `dashcaddy-api/` root level (auth-manager.js, credential-manager.js, etc.). Move into organized subdirs under `src/` (e.g., `src/managers/`, `src/security/`, `src/docker/`). Update all require() paths. This is a big refactor — run tests after.
+- **result:** Refactor complete on `krystie-improvements` branch (879/879 tests passing on branch). Merged into main via commit `283121e` after resolving 24 conflicts. Post-merge regression check surfaced one additional latent path bug from DC-005: `src/monitoring/health-checker.js` still had `require('./platform-paths')` (relative to `src/monitoring/`), but `platform-paths.js` lives at top level — fixed in commit `9688e64` to `require('../../platform-paths')`. Without that fix, 59 cascading test failures in `health-checker.test.js`. Final post-merge state: 921/922 tests passing.
+- **remaining latent bugs (tracked, NOT yet fixed):** The DC-005 path-rewrite script left depth-2 route files (`routes/auth/*.js`, `routes/recipes/*.js`, `routes/apps/*.js`, `routes/arr/*.js`, `routes/config/*.js`) with `'../../../src/...'` — **3 levels up instead of 2**, which goes above `dashcaddy-api/` entirely. Required path should be `'../../src/...'` for depth-2 routes. Tests didn't catch this because no test previously imported any depth-2 route (only depth-1 routes like `routes/services.js` were tested). Confirmed-broken imports (with file → offending line): `routes/auth/totp.js:2` (FIXED in DC-006 commit), `routes/auth/keys.js:2`, `routes/auth/sso-gate.js:2-3`, `routes/auth/session-handlers.js:2-3`, `routes/recipes/manage.js:2-3`, `routes/recipes/deploy.js:2-3`, `routes/recipes/index.js:2-3`, `routes/config/assets.js:2-4`, `routes/config/settings.js:2-4`, `routes/config/backup.js:2-4`, `routes/apps/restore.js:2`, `routes/apps/compose.js:2-3`, `routes/apps/deploy.js:2-5`, `routes/apps/helpers.js:2-3`, `routes/apps/templates.js:2-3`, `routes/apps/removal.js:2-3`, `routes/arr/detect.js:2`, `routes/arr/smart-connect.js:2`, `routes/arr/credentials.js:2-3`, `routes/arr/helpers.js:2`, `routes/arr/config.js:2-5`, `routes/arr/plex.js:2`. The fix is mechanical (3 → 2 levels) but touches ~22 files — should be its own PR/commit for clean review.
+
+### DC-006: Add integration test for TOTP auth flow
+- **status:** done
+- **owner:** krystie
+- **details:** End-to-end test: no token → 401, wrong token → 403, valid TOTP → session token → authenticated request succeeds. Cover the full `/api/auth/check` → session → endpoint flow.
+- **result:** Added `dashcaddy-api/__tests__/routes/auth.totp.routes.test.js` — 25 tests, all passing. Covers: GET `/api/totp/config`, POST `/api/totp/setup` (generate + normalize + reject invalid Base32), POST `/api/totp/verify-setup` (missing/bad/no-pending/valid-code paths), POST `/api/totp/verify` (login — 400/400/401/200), GET `/api/totp/check-session` (passthrough when disabled + 401 no-session + 200 valid-session — the BACKLOG "no token → 401 / authenticated request succeeds" pair), POST `/api/totp/disable` (400/401/200), POST `/api/totp/config` (valid/invalid/never-disables), plus the full end-to-end flow setup→login→check-session→disable and an otplib-not-stubbed sanity check. Uses real `otplib` for code generation (real TOTP math), mocks `credentialManager`/`session`/`totpConfig`/`saveTotpConfig` only. Full suite: 904/904 pass (879 baseline + 25 new). ESLint clean for the new file.
+- **side-effect (DC-005 latent bug fix):** While writing the test I discovered `routes/auth/totp.js` had broken require paths from the DC-005 refactor (`'../../../src/utilities/errors'` was 3 levels up from `routes/auth/` — wrong by 1). The test couldn't even load the route without this fix. Fixed in this commit (`'../../src/utilities/errors'` and `'../../src/utils/responses'`). **Same depth bug exists in other depth-2 route files — see DC-005 note above.**
+
+### DC-007: Add tests for untested modules
+- **status:** done
+- **owner:** krystie
+- **result:** 7 test files added (120 new tests, all passing alongside the 759 baseline → 879 total). Files: `__tests__/dns-propagation.test.js` (9), `__tests__/notification-manager.test.js` (18), `__tests__/ssl-monitor.test.js` (13), `__tests__/log-digest.test.js` (11), `__tests__/metrics.test.js` (21), `__tests__/config-drift-detector.test.js` (19), `__tests__/auto-restart-manager.test.js` (29).
+- **details:** These modules have NO test coverage: `dns-propagation.js`, `notification-manager.js`, `ssl-monitor.js`, `log-digest.js`, `metrics.js`, `config-drift-detector.js`, `auto-restart-manager.js`. Add at least basic smoke tests for each.
+

+
+## P2 — Polish & DX
+
+### DC-008: Update CLAUDE.md for cross-platform accuracy
+- **status:** done
+- **owner:** hermes
+- **details:** CLAUDE.md references Windows-specific paths (C:/caddy/, e:/CaddyCerts/) as if they're universal. DashCaddy runs on Linux (Docker on DNS2) and Windows (SAMI-PC). Document both deployment targets clearly.
+- **result:** Added a new "Linux Deployment (DNS2 / Contabo VPS)" section after the existing Windows docs (preserved verbatim) and before the "Project Info" footer. The new section documents: production paths (`/opt/dashcaddy/`, `/var/www/dashcaddy-status/`, `/etc/dashcaddy/`), container mount points with the `/app/data/` auto-resolve fallback, the three-filesystem frontend trap (source vs live vs build-context), common admin commands, a Windows-vs-Linux differences table, and four Linux-specific gotchas (Caddy network_mode host, credentials.json perms, CORS_ORIGINS vs Tailscale, TS_AUTHKEY provisioning). Also updated the "Project Info" version field from stale `1.0` to current `1.13.4` and added the Linux-side default TLD (`.home`).
+
+### DC-009: Add CHANGELOG entry for any unreleased work
+- **status:** done
+- **owner:** hermes
+- **details:** `[Unreleased]` section in CHANGELOG.md is empty. Any fixes done should be documented there before tagging a release.
+- **result:** Populated the `[Unreleased]` section with all unreleased work since v1.5.0: Security (TOTP 4-part recovery), Added (OpenClaw routes, auto-backup, monitoring widget, Sami Files template, unified logger, notification manager, update UX, 120 new tests across 7 files), Changed (DC-010 response standardization across 9 route files, /api/v1/ versioning, release.sh hardening), Fixed (DC-011 credential route regression, DC-004 ESLint cleanup, workflow engine init, container-logs wireModal misuse, CSP hash mismatch, SW cache tag, updater false-positive loop), Removed (legacy test scripts moved to scripts/legacy/ preserved-not-deleted, stale root files, dead routes/ directory). Each entry cites the source commit hash for traceability.
+
+### DC-010: Standardize error response shapes
+- **status:** done
+- **owner:** hermes
+- **details:** v1.13.4 standardized route responses to use helpers, but some modules still use raw `res.json()`. Grep for remaining `res.json(` in route handlers and convert to response helpers.
+- **result:** All bare `{success: true, ...}` envelopes across route files now go through `success()` (or `ok()` where the older alias is wired in). Files converted in this push (4 commits): browse/logs/sites (cron), updates/notifications/tailscale/events/workflows/openclaw/dns/health/ca (this sprint) — 9 files, 62 calls. `services.js` line 360+368 left alone (intentional raw-array responses for the frontend wire contract — separate cleanup). Error-path `res.status(4xx/5xx).json({success:false, error:...})` envelopes also left as-is (`ok()` helper would set `success:true` — wrong tool for error shapes). Net result: only 2 intentional raw-array calls remain in routes/; everything else routes through `response-helpers`. 750/750 tests pass at every checkpoint.

+
+## Coordination Rules
+
+1. **Always `git pull` before starting work.**
+2. **Claim a task by editing BACKLOG.md:** set `status: in-progress` and `owner: hermes` or `owner: krystie`.
+3. **Commit BACKLOG.md claim first**, then start coding.
+4. **Run tests before pushing:** `cd dashcaddy-api && npx jest --passWithNoTests`
+5. **Push to `main`** — use `http://sami7777:<token>@100.98.123.59:3000/sami7777/dashcaddy.git`
+6. **Update BACKLOG.md** when done: set `status: done`, add brief result under the task.
+7. **Never work on a task another bot has claimed** (status: in-progress).
+8. **Quality bar:** this is a public-release product. No hacks, no env-var workarounds, no per-machine patches. Fixes go in the shared codebase.
+9. **VERSION bump:** when a batch of tasks is done, bump patch version in package.json + VERSION file, update CHANGELOG, tag.

+### Security
+- **TOTP recovery system (4-part defense against permanent lockout).** Pre-lockout: `.bak` fallback credentials file checked at every TOTP init, used silently when primary fails. Diagnostic: `/recovery-info` endpoint + `/recovery-panel` UI on the entry screen with one-click "Import Backup" + "Download Backup" buttons. Post-lockout: friction-free `.license-secret` restore flow. (`d230b39`, `3dff49c`, `7bbd969`)
+
+### Added
+- **OpenClaw routes** — full set under `/openclaw` prefix: connect, disconnect, status, host discovery. `docker.client` wrapper fixed; duplicate `/apps/` paths stripped across sub-routers.
+- **Auto-backup scheduling (premium tier)** + storage-limit enforcement (prune oldest when `maxStorageBytes` exceeded) + restore-from-backup on update rollback. Bundled workflows included out-of-the-box.
+- **Monitoring widget on main dashboard** — CPU/mem data flattened, health summary added; `/api/monitoring/stats` exposed as a public route with rate-limit.
+- **Sami Files template** — logPath wired into the template and mounted in `start.sh`.
+- **Unified logger** — single source of truth for logs, errors, and audit events.
+- **Notification manager + resource alerting** (premium tier).
+- **Update UX** — badge→modal flow, orange update button, "Update All", toast notifications, workflow triggers.
+- **Comprehensive test suite additions:** 7 new test files (`dns-propagation`, `notification-manager`, `ssl-monitor`, `log-digest`, `metrics`, `config-drift-detector`, `auto-restart-manager`) — 120 new tests, all passing.
+
+### Changed
+- **Route response standardization (DC-010).** Every `{success, ...}` envelope across 9 route files now flows through `response-helpers` (`success()` / `ok()`). Only 2 intentional raw-array calls remain (`routes/services.js` lines 360+368 — frontend wire contract). Error-path envelopes use `error()` separately. ~62 calls converted across `browse/logs/sites/updates/notifications/tailscale/events/workflows/openclaw/dns/health/ca`.
+- **`/api/v1/` versioning:** all routes mounted under `/api/v1/`. Legacy un-versioned `/api/` mount removed. Frontend, OpenAPI spec, DashCA pages, and all internal path matchers (CSRF exclusions, auth public routes, audit log, rate-limit mounts) updated.
+- **`scripts/release.sh`** now stages build-rewritten files (`sw.js`, `index.html`) for the published tarball, copies `VERSION` into the tarball, and writes both `dashcaddy-api/package.json` AND root `VERSION` on every release. No more version drift.
+
+### Fixed
+- **Credential route path regression (DC-011).** `routes/services.js` had dropped the `/services/` prefix from credential routes (POST/DELETE/GET) during a refactor, causing 4 test failures and a live 404. Re-applied the prefix; also fixed a latent `ReferenceError` where invalid serviceIds called `ctx.errorResponse()` in a factory-destructured module (replaced with the imported `errorResponse` helper).
+- **19 ESLint warnings (DC-004).** Reached zero warnings across `src/` — most cleared by the refactor, the final 3 (`require-await` on `resyncHealthChecker`, two `max-depth` violations) fixed in `src/app.js`.
+- **Workflow engine init broken** — `fetchT` not imported, `NotificationManager` constructor missing `new`, `servicesStateManager` not hoisted. Fixed; events now fire on startup.
+- **Container-logs feature was misusing `wireModal`** — short-circuited the rest of `features.js` and broke unrelated dashboard features. Replaced with the correct wiring.
+- **CSP hash mismatch** between Windows and Linux builds — now computed on LF-normalized `index.html` so hashes are identical across platforms.
+- **SW cache tag** now derived from bundle content hash, so the service worker invalidates correctly when bundle content changes.
+- **Updater false-positive loop** when commit hash was unknown — fixed.
+
+### Removed
+- Stale ad-hoc test/debug scripts (`comprehensive-test.js`, `test-security-fixes.js`) moved to `dashcaddy-api/scripts/legacy/` (preserved, not deleted — 875 lines of security test coverage retained as a manual smoke test).
+- Stale root-level files: `*.bak`, `server-old.js`, and ad-hoc reports (`DEPLOYMENT-SUCCESS.md`, `FINAL-DEPLOYMENT-REPORT.md`, `DESLOPIFICATION-ROADMAP.md`, etc.) — disk-only cleanup, already gitignored.
+- Dead `routes/` directory at API root (replaced by `src/routes/`).
+
+### Security (TOTP integration)
+- TOTP integration tests now cover the full `/api/auth/check` → session → endpoint flow (DC-006). 25 new tests including: `setup` (generate + normalize + reject invalid Base32), `verify-setup` (missing/bad/no-pending/valid-code paths), `verify` login (400/400/401/200), `check-session` (passthrough when disabled + 401 no-session + 200 valid-session), `disable`, `config` (valid/invalid/never-disables), and full end-to-end setup→login→check-session→disable.
+
+### Fixed (from merge)
+- **routes/updates.js** — krystie's branch had `if (!ok)` referencing the helper function instead of the `secretOk` boolean. Would have 500'd every `/system/update-notify` request. Caught during merge, kept my version with the correct boolean check.
+- **routes/notifications.js** — two places where she replaced `res.json({success: result.success, ...})` with `ok(...)` would have forced `success: true` for partial-failure delivery. Kept my version with explicit `res.json` to preserve the semantic.
+
+## [1.13.4] - 2026-06-12
+
+### Changed
+- Standardized all route handler responses to use helpers from `src/utils/responses.js`
+  (`ok`, `errorResponse`, `successMessage`, `notFound`, `validationError`, `forbidden`,
+  `unauthorized`, `conflict`). ~160 raw `res.json()` calls converted across 32+ files.
+  No behavior changes — response shapes are identical. This ensures future schema
+  changes (e.g., adding a `requestId` envelope) only need to update one module.
+- Fixed `error` vs `errorResponse` signature mismatch in `routes/health.js` CA cert
+  endpoint. The `error` helper takes `(res, message, statusCode)` while `errorResponse`
+  takes `(res, statusCode, message, extras)` — the wrong alias was being used for
+  calls that needed the 4-argument form.
+- Updated `middleware.js`, `csrf-protection.js`, `error-handler.js`, and
+  `license-manager.js` to use response helpers for rejection/error responses
+  instead of inline `res.status().json()`.
+
+### Note
+- 4 pre-existing test failures in `services.routes.test.js` (credential storage)
+  remain from before this release. They are unrelated to the standardization pass.

+The Windows path sections above describe the **SAMI-PC** deployment. DashCaddy also runs as a Docker container on Linux (DNS2 = `194.233.88.206` / Tailscale `100.121.150.22`). The Linux deployment uses a different layout driven by `start.sh` and `docker run` bind mounts.

+|---|---|
+| `/app/data/credentials.json` | `/opt/dashcaddy/credentials.json` |
+| `/app/data/.encryption-key` | `/opt/dashcaddy/.encryption-key` |
+| `/app/data/services.json` | `/opt/dashcaddy/services.json` |
+| `/caddyfile` | `/etc/dashcaddy/Caddyfile` |
+
+Note: the app must auto-resolve both `/app/data/...` AND the older `/app/...` layout (where files mounted directly to `/app/`). The `credential-manager.js` and `crypto-utils.js` modules handle this fallback. This is intentional — fresh installs get `/app/data/`, legacy installs keep working without env-var overrides.
+
+### Three-filesystem frontend trap (Linux)
+The dashboard frontend lives on **three** separate paths that get confused:
+
+1. **Source** — `/opt/dashcaddy/status/` — what you edit
+2. **Live** — `/var/www/dashcaddy-status/` — what Caddy serves to browsers
+3. **Build context** — `/opt/dashcaddy/dashcaddy-api/` — what `docker build` uses
+
+Editing `/opt/dashcaddy/status/index.html` and restarting the container does **nothing** visible until you run the build (which writes to `/var/www/dashcaddy-status/`). Always rebuild + container-recreate together. See the `dashcaddy` skill § Deploy cycle for the exact sequence.
+
+### Common commands (Linux)
+```bash
+# Edit Caddyfile then reload (no restart needed)
+curl -X POST http://localhost:2019/load \
+  -H "Content-Type: text/caddyfile" \
+  --data-binary @/etc/dashcaddy/Caddyfile
+
+# View container logs
+docker logs dashcaddy-api --tail 200
+
+# Rebuild + restart after API code change
+cd /opt/dashcaddy && git pull
+cd /opt/dashcaddy/dashcaddy-api && docker build -t dashcaddy-api:local .
+docker stop dashcaddy-api && docker rm dashcaddy-api

+| DNS server | DNS2 (100.74.102.61) primary | DNS2 (100.121.150.22 / 194.233.88.206) — **is** the primary |
+
+### Linux-specific gotchas
+- **Caddy needs `network_mode: host`** (or `--network host`) so it can bind :80 and :443 directly. Bridge mode + port mapping also works, but `network_mode: host` is simpler for a single-host setup.
+- **`credentials.json` permissions matter** — file mode `0600`, owned by the same UID the container runs as. If the host root creates it but the container runs as `node` (uid 1000), the API will fail to read it. Either `chown 1000:1000` or run the container as `--user 0`.
+- **Don't use `localhost` in the API's CORS_ORIGINS** — it conflicts with the Tailscale IP. Use the actual `https://dashcaddy<your-tld>` URL.
+- **Tailscale cert provisioning** — set `TS_AUTHKEY` in `/etc/dashcaddy/tailscale.env` (mode 0600) before first start. Without it, the magic DNS hostname will resolve but TLS will fail.

+ *   - no code      → 400 (ValidationError)
+ *   - wrong code   → 401 (AuthenticationError)
+ *   - valid TOTP   → 200 + session cookie + CSRF token
+ *   - check-session with valid session → 200 { authenticated: true }
+ *   - check-session without session    → 401 (AuthenticationError)
+ *
+ * Uses real otplib for code generation (so we exercise the actual TOTP math)
+ * but mocks credentialManager, session, totpConfig, and saveTotpConfig —
+ * because those modules own their own state machines (disk, cookies, file)
+ * that don't belong in a routes-level test.
+ *
+ * NOTE: this test exercises the src/ refactored module layout (DC-005).
+ * It depends on routes/auth/totp.js requiring ../../src/utilities/errors and
+ * ../../src/utils/responses — fix the relative paths in totp.js if they
+ * regress (see commit log for DC-006).
