+# CI build notes
+
+## 2026-04-24
+
+- **Observed failure while reproducing workflow checkout locally:** the `Checkout code` step ran `git remote add origin ...` unconditionally. In a workspace that already had an `origin` remote, the job failed with `error: remote origin already exists.` and exited before `docker build`.
+- **Why this matters for act_runner:** self-hosted Gitea runners can reuse working directories or start from repositories that already contain Git metadata, so checkout logic must be idempotent.
+- **Applied fix:** changed `.gitea/workflows/package.yml` to initialize Git only when needed, use `git remote set-url origin ...` when `origin` already exists, and force-clean the workspace after checking out `FETCH_HEAD`.
+- **Safety improvement for remote validation:** tags ending with `-test` now run the build verification path only. They skip registry login, image push, `latest` updates, and the deploy webhook so act_runner can be tested without deployment side effects.
+- **Current local result:** `npm run lint`, `npm run test -- --runInBand`, `npm run build`, `docker build ...`, and `npm run build` inside `gitea/runner-images:ubuntu-22.04` all completed successfully after the workflow adjustment.
+- **Non-blocking note:** local Jest run reported a haste-map naming collision between `package.json` and `.next/standalone/package.json`; tests still passed, and this does not affect the current image-build workflow.
