 - **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:** in-progress
+- **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.
-- **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. **MERGED into main via this commit** — 25 conflicts resolved (route files I touched, status dist files, infra docs). See merge commit for full resolution list.
+- **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.
