Build and Push Container / build-and-push (push) Successful in 23s
**Phase 03 final verification — all green** - Verified (all tasks already in `complete/`): snippet/Dockerfile/nginx.conf wiring, `scripts/check-headers.sh`, guardrail teeth, restored config byte-identical. - Tests (full suite): `./build.sh` → OK; `npm test` → **46 passed, 0 failed**; `bash .agents/validate.sh` → **exit 0** (46/46 + `HEADER CHECK PASSED` + hygiene gates); no leftover podman images. - Completion criteria: - `nginx-security-headers.inc` with 4 `add_header … always;` lines — ✅ - `nginx.conf`: 0 inline security `add_header` (cache headers only), 3/3 locations `include` snippet — ✅ - `server_tokens off;` in server block — ✅ (live proof: `Server: nginx`, no version) - `./scripts/check-headers.sh` → `HEADER CHECK PASSED`, OK on `/`, `/index.html`, hashed asset — ✅ (also confirmed all 4 headers + correct Cache-Control on 404 fallback) - `./build.sh && npm test` fully green — ✅ - No behavior change (terminal/vim/achievements/menu suites) — ✅ - Negative check re-run: dropping one `include` → `FAIL … on /style.<hash>.css`, exit 1 — ✅ - Docs: README.md & AGENTS.md reviewed in full against actual state (commands, ports 8123/18099, header mechanism, CI tags vs `.gitea/workflows/build-push.yml`, Node ≥20 engine floor, innerHTML/neofetch exception at `terminal.js:487`, simulated curl/wget guards) — **verified consistent, no changes needed**. - Notable: check-headers.sh aborts at the first failing path via `set -e` before printing `HEADER CHECK FAILED` — README's wording matches this exactly (verified empirically). PLAN.md's "44 tests" count is stale (now 46) but PLAN.md is locked — left for the user. - No live-infra changes (no HSTS in container; edge/Caddy untouched). - Next pending phase: `04_huntington_role`.
