+# CASAN PLAN 05 — CI/CD & Release Gate
+
+> Status 2026-07-06: **CI gate MVP implemented + locally syntax/filter verified**.
+> A reusable local/CI gate script now exists, and a Gitea Actions workflow is
+> wired to run it on `main` push/PR. Package publishing/release automation is
+> still planned.
+
+## Delivered
+
+| Capability | Where | Verification |
+|---|---|---|
+| One-command harness CI gate | `.specify/scripts/bash/ci-harness-gate.sh` | `bash -n`; local suites are callable in safe order |
+| Safe test order | `run-casan4` runs first because it rewrites `.specify/logs`; hardening suites run after | script order |
+| Per-suite timeout | `CASAN_CI_STEP_TIMEOUT_SEC` protects CI from hung model/security subprocesses | full gate attempt exposed a long A6 run; timeout wrapper added |
+| Filtered local verification | `CASAN_CI_SUITE_FILTER='phase2-sourcegen|phase10-traceability'` | `CI_GATE_SUMMARY PASS=2 FAIL=0 SKIP=15` |
+| Source-gen gate included | `phase2-sourcegen-tests.sh` included | sourcegen 3/0 |
+| Traceability gate included | `phase10-traceability-tests.sh` included | traceability 3/0 |
+| Frontend runtime tests included | `npm test -w frontend` when npm is present | frontend Vitest path |
+| Optional Docker local-prod lab | `CASAN_CI_RUN_INFRA_LAB=1` runs `phase-prod-infra-lab-tests.sh` only when Docker Compose is available | skip-aware by default |
+| Gitea Actions workflow | `.gitea/workflows/harness-ci.yml` | workflow calls `ci-harness-gate.sh` |
+
+## Gate contents
+
+Required gate:
+
+- `run-casan4-harness-tests.sh`
+- `adversarial-harness-tests.sh`
+- `phase1-track-a-tests.sh`
+- `phase2-track-c-tests.sh`
+- `phase2-sourcegen-tests.sh`
+- `phase3-evidence-pack-tests.sh`
+- `phase3-model-router-tests.sh`
+- `phase-h5-approval-tests.sh`
+- `phase-h5-infra-tests.sh`
+- `phase-h6-agentops-tests.sh`
+- `phase-c7-incident-tests.sh`
+- `phase-h4-multilingual-tests.sh`
+- `phase-c6-sandbox-tests.sh`
+- `phase-h4-split-inject-tests.sh`
+- `phase10-traceability-tests.sh`
+- `npm test -w frontend` when npm is available
+
+Optional gate:
+
+- `phase-prod-infra-lab-tests.sh` when `CASAN_CI_RUN_INFRA_LAB=1` and Docker
+  Compose is available.
+
+## Remaining work
+
+| Priority | Work | Done when |
+|---|---|---|
+| P1 | Run the workflow on the real Gitea runner | Gitea run shows green `CASAN Harness CI` on `main` |
+| P2 | Investigate slow/hung A6 full-gate local run | `phase1-track-a-tests.sh` A6 completes under timeout consistently on Mac/runner |
+| P3 | Decide Docker availability on runner | `CASAN_CI_RUN_INFRA_LAB=1` is enabled only if runner mounts Docker safely |
+| P4 | Package/release automation | `npm pack` or release artifact for `fpt-casan-sdd-harness` is generated and versioned |
+| P5 | Backend full `npm test` unblock | Prisma/MySQL-vs-SQLite test-infra mismatch is resolved or split into a proper MySQL service job |
+| P6 | Branch protection | Merge requires green CI gate |
+
+## Local commands
+
+```bash
+cd AINative_OKR_CASAN5
+bash -n .specify/scripts/bash/ci-harness-gate.sh
+CASAN_CI_RUN_FRONTEND=1 CASAN_CI_RUN_INFRA_LAB=0 bash .specify/scripts/bash/ci-harness-gate.sh
+CASAN_CI_RUN_INFRA_LAB=1 bash .specify/tests/phase-prod-infra-lab-tests.sh
+```
+
+## Notes
+
+- `backend npm test` is not part of the required CI gate yet because the current
+  repo has a known pre-existing mismatch: `schema.prisma` is MySQL-oriented but
+  `backend/scripts/setup-sqlite.mjs` applies migrations to SQLite.
+- The workflow installs Node 20 inside the Gitea job if the runner image does
+  not already provide `node`/`npm`.
