+### 2026-06-07 — backend@55321c0, frontend@525d50a — restore last-green Woodpecker build procedure
+
+**Commits:** `55321c0` `525d50a`
+**Touched:** backend `Dockerfile.prod`, `.woodpecker/production.yml`, `package.json`, `package-lock.json`; frontend `.woodpecker/production.yml`, `Dockerfile`, `package.json`; docs `09 - Audits/Activity Log.md`, `11 - Testing/Smoke and Regression Procedure.md`
+**Why:** Restore backend build/deploy procedure to match the last successful backend build at `5d7d2af` and restore the paired frontend production build shape from `ade7352`. The prior Docker cleanup/prune hardening commits were too broad for the CI authentication/storage investigation and have been superseded. Backend again uses the original two-stage Dockerfile with builder `npm ci`, transpile, production `npm ci --omit=dev`, and `dist` copy. Backend/frontend Woodpecker production pipelines again run the simple local Docker build and compose deploy without cleanup blocks.
+**Verification:** backend/frontend `woodpecker-cli lint .woodpecker/production.yml`; backend production build files diff clean against `5d7d2af`; frontend production build files diff clean against `ade7352` except `NEXT_PUBLIC_APP_VERSION`; backend/frontend scoped `git diff --check`; backend/frontend version metadata confirmed at v2.9.42. Woodpecker backend `#93` passed clone, typecheck, build-and-deploy, and notify; frontend `#86` passed clone, build-and-deploy, and notify.
+**Linked docs updated:** [[11 - Testing/Smoke and Regression Procedure]]
