BACKLOG: mark DC-006 done, document DC-005 latent path bug

DC-006 marked done with 25-test result summary + 904/904 test note.
DC-005 annotated with two critical notes:
  - Latent require-path bug in depth-2 routes (mechanical 3->2 fix needed in ~22 files)
  - Branch state vs origin/main divergence (need coordinated merge, not silent FF)

 ## P0 — Must Fix (blocks public release)
 
 ### DC-001: Fix 4 failing tests in services.routes.test.js
-- **status:** in-progress
+- **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-002: Sync VERSION file
-- **status:** todo
-- **owner:** 
+- **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:** todo
-- **owner:** 
+- **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:** todo
-- **owner:** 
+- **status:** in-progress
+- **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.
 
 ### DC-005: Organize top-level modules into src/
-- **status:** todo
-- **owner:** 
+- **status:** in-progress
+- **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.
+- **latent bug (discovered during DC-006, NOT yet fixed):** The DC-005 refactor's 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.
+- **branch state:** Work is complete on `krystie-improvements` (HEAD `7bc2a20`) with 879/879 tests passing on the branch. **NOT YET ON MAIN** — `origin/main` has since moved past the refactor with ~28 newer commits (DC-008/009/010/011, TOTP 4-part recovery, monitoring widget, unified logger, response-shape standardization). `git diff origin/main..HEAD` is 187 files / 10823 insertions / 3187 deletions — large enough to need careful coordination, not silent fast-forward. See Discord/Sami for proposed merge plan.
 
 ### DC-006: Add integration test for TOTP auth flow
-- **status:** todo
-- **owner:** 
+- **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 below.**
 
 ### DC-007: Add tests for untested modules
-- **status:** todo
-- **owner:** 
+- **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.

+ * Integration tests for routes/auth/totp.js — the full TOTP auth flow.
+ *
+ * Covers the BACKLOG.md DC-006 acceptance criteria:
+ *   - 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).
