+# Phase 06 Plan 03: CI/CD Pipeline Summary
+
+**Gitea Actions multi-stage pipeline (lint+type-check -> vitest -> docker build+deploy) with act_runner compose definition and setup runbook**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-06-25T08:56:13Z
+- **Completed:** 2026-06-25T08:59:12Z
+- **Tasks:** 2 completed, 1 awaiting human verification (Task 4)
+- **Files created:** 3
+
+## Accomplishments
+
+- act_runner Docker Compose service definition with ephemeral mode and Docker socket mount
+- CI/CD setup runbook covering Gitea remote, runner registration, secrets, and security notes
+- Three-job Gitea Actions pipeline: quality (Biome lint + TypeScript type-check), test (Vitest), build-deploy (docker compose build + up)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Set up Gitea remote and register act_runner** -- completed prior to this execution (checkpoint:human-action)
+2. **Task 2: Define act_runner service and CI/CD setup runbook** -- `c0e3293` (feat)
+3. **Task 3: Create .gitea/workflows/ci.yml multi-stage pipeline** -- `756925b` (feat)
+4. **Task 4: Trigger the pipeline with a real push** -- checkpoint:human-verify (awaiting)
+
+## Files Created
+
+- `.gitea/workflows/ci.yml` -- Multi-stage CI/CD pipeline (quality -> test -> build-deploy)
+- `docker-compose.ci.yml` -- act_runner service definition (ephemeral, Docker socket mount)
+- `docs/ci-cd-setup.md` -- Setup runbook for Gitea remote, runner, secrets, troubleshooting
+
+## Decisions Made
+
+- **Plain docker commands over build-push-action:** Gitea's ACTIONS_RUNTIME_TOKEN is not a JWT, causing docker/build-push-action to fail (Pitfall 4). Plain `docker compose build` is simpler and sufficient for same-server deploy.
+- **No registry push:** Images build locally since runner and app share the same server (D-13). Eliminates registry infrastructure and network overhead.
+- **Separate compose file:** `docker-compose.ci.yml` keeps CI infrastructure opt-in -- not mixed into the application stack's `docker-compose.yml`.
+- **Ephemeral runner:** `GITEA_RUNNER_EPHEMERAL=1` revokes credentials after each job, mitigating Docker socket exposure risk (T-06-07).
+
+## Deviations from Plan
+
+None -- plan executed exactly as written.
+
+## Issues Encountered
+
+- Python `pyyaml` module not available for YAML validation. Used Node.js structural checks instead. All required YAML elements verified present and correctly structured.
+
+## Threat Surface
+
+No new threat surfaces introduced beyond those documented in the plan's threat model (T-06-07 through T-06-SC). All mitigations applied:
+- T-06-08: Secrets referenced via environment variables, never hardcoded
+- T-06-SC: Official `gitea/act_runner` image used; CI actions pinned to major versions (checkout@v4, setup-node@v4, action-setup@v4)
+
+## Next Phase Readiness
+
+- Pipeline ready for first real push (Task 4 checkpoint pending human verification)
+- After push verification, INFRA-04 will be fully validated
+- All future pushes to main will automatically run lint, type-check, tests, and redeploy
+
+## Self-Check: PASSED
+
+- All 3 created files verified on disk
+- Both task commits (c0e3293, 756925b) verified in git log
