feat(sdlc): staging environment + automated staging→prod pipeline

- pr-checks.yml: PR gate — frontend typecheck+jest, backend import smoke, image builds (no push), Claude AI review posted as PR comment (severe findings block merge) - deploy.yml (replaces build-and-push.yml): merge to main builds+pushes images tagged sha-<sha>/staging, deploys the staging Portainer stack via webhook, runs Playwright E2E journeys against staging, then retags the verified images :prod (previous kept as :prod-previous) and deploys prod - docker-compose.portainer.staging.yml: second Portainer stack — :staging images, sc_staging_* names, own macvlan IPs, Airflow on 8081; data bootstrapped from source via the staging Airflow DAGs - prod compose now pins :prod instead of :latest (only the promotion step moves it; :latest is no longer published) - e2e/: 6 Playwright journeys (search, postcode, detail, compare, rankings) driven by BASE_URL — the promotion gate - scripts/ci/ai_review.py: Claude review with structured JSON findings - docs/DEPLOY.md: full SDLC doc incl. one-time setup checklist and rollback - replaced removed 'next lint' with tsc typecheck; fixed stale jest tests (slug URLs, N/A formatting, stable trend, fake-timer setup) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PqGhF93UrpDNvXBLMjJENL

+Full details in `docs/DEPLOY.md`. The short version:
+
+- **Never push to `main` directly.** Work on a feature branch and open a PR;
+  branch protection requires the PR checks (typecheck, tests, builds, AI review)
+  to pass before merge.
+- Merging to `main` deploys automatically: images are built once, deployed to
+  the **staging** Portainer stack, verified by the Playwright journeys in
+  `e2e/`, and only then retagged `:prod` and rolled out to production.
+- If you change user-facing behaviour, update or extend the `e2e/` journey
+  tests in the same PR — they are the promotion gate.
+
 ## Recent Changes

+- Added staging environment + automated staging→prod pipeline (Gitea Actions)
 - Migrated from CSV file storage to PostgreSQL database
 - Added location-based search using postcode geocoding
 - Added local authority filter to rankings

+# Portainer Stack Definition for School Compare — STAGING
+#
+# Deploy this as a *separate* Portainer stack (e.g. "schoolcompare-staging")
+# alongside the production stack. Differences from production:
+#   - images pinned to :staging (pushed by every merge to main, before the E2E gate)
+#   - sc_staging_* container names
+#   - own macvlan IPs (STAGING_DB_IP / STAGING_FRONTEND_IP env vars)
+#   - Airflow UI published on 8081 (prod uses 8080)
+#   - volumes are isolated automatically: Portainer prefixes volume names with
+#     the stack name, so this stack gets its own postgres/typesense/airflow data
+#
+# Portainer environment variables (set in Portainer UI -> Stack -> Environment):
+#   DB_USERNAME            — PostgreSQL username
+#   DB_PASSWORD            — PostgreSQL password

+# SDLC & Deployment Pipeline
+
+SchoolCompare uses a fully automated staging → production pipeline on Gitea
+Actions. AI writes the code on feature branches; the pipeline verifies every
+change on a staging environment before promoting the exact same images to
+production. Human input is directional only: feature requests, PR review if
+desired, and intervention when a gate fails.
+
+## The flow
+
+```
+feature branch (AI-authored)
+   │  PR to main
+   ▼
+PR checks (.gitea/workflows/pr-checks.yml)
+   typecheck + unit tests + backend smoke + image builds (no push)
+   + Claude code review posted as a PR comment (severe findings fail the check)
+   │  merge (branch protection requires green checks)
+   ▼
+Deploy pipeline (.gitea/workflows/deploy.yml)
+   1. build & push images        → tags sha-<sha>, staging
+   2. staging Portainer webhook  → wait for staging health
+   3. Playwright E2E journeys against staging
+   4. retag sha-<sha> → :prod    (same bytes — build once, promote the image)
+      previous :prod saved as :prod-previous
+   5. prod Portainer webhook     → wait for prod health
+```
+
+Key principle: **build once, promote the exact image**. Production pins `:prod`,
+which only moves after the E2E gate passes on staging. Nothing tags `:latest`
+anymore.
+
+## Branch & PR workflow
+
+- `main` is protected: no direct pushes, PRs require green status checks.
+- All work (human or AI) happens on feature branches → PR to `main`.
+- Merging to `main` **is** the release action. If staging or the E2E gate
+  fails, production is untouched.
+
+## Environments
+
+| | Production | Staging |
+|---|---|---|
+| Portainer stack file | `docker-compose.portainer.yml` | `docker-compose.portainer.staging.yml` |
+| Image tag | `:prod` | `:staging` |
+| Container prefix | `sc_` / `schoolcompare_` | `sc_staging_` |
+| Frontend macvlan IP | 10.0.1.150 | `STAGING_FRONTEND_IP` (default 10.0.1.151) |
+| Postgres macvlan IP | 10.0.1.189 | `STAGING_DB_IP` (default 10.0.1.190) |
+| Airflow UI port | 8080 | 8081 |
+| Volumes | stack-prefixed | stack-prefixed (fully isolated) |
+
+Staging gets `:staging` images on every merge to main — even ones that later
+fail the E2E gate. That's the point: staging absorbs the risk.
+
+## Gitea repository secrets
+
+| Secret | Purpose |
+|---|---|
+| `REGISTRY_TOKEN` | push images to privaterepo.sitaru.org (already set) |
+| `ANTHROPIC_API_KEY` | Claude PR review (`scripts/ci/ai_review.py`) |
+| `GITEA_TOKEN` | post PR review comments (needs issue-comment scope) |
+| `PORTAINER_STAGING_WEBHOOK` | staging stack redeploy webhook URL |
+| `PORTAINER_PROD_WEBHOOK` | production stack redeploy webhook URL |
+| `STAGING_BASE_URL` | e.g. `http://10.0.1.151:3000` — health poll + E2E target |
+| `PROD_BASE_URL` | e.g. `http://10.0.1.150:3000` — post-promotion health poll |
+
+## One-time setup checklist
+
+1. **Create the staging stack** in Portainer from
+   `docker-compose.portainer.staging.yml` (stack name e.g.
+   `schoolcompare-staging`). Set the same environment variables as prod plus
+   `STAGING_DB_IP` / `STAGING_FRONTEND_IP` if the defaults clash.
+2. **Enable webhooks** on both stacks (Portainer → Stack → Webhook) and store
+   the URLs as `PORTAINER_STAGING_WEBHOOK` / `PORTAINER_PROD_WEBHOOK`. Remove
+   the old hardcoded webhook usage (now gone from the workflows).
+3. **Add the remaining secrets** listed above in Gitea → repo → Settings →
+   Actions → Secrets.
+4. **Protect `main`** in Gitea → Settings → Branches: require PRs, require the
+   pr-checks status checks (frontend, backend, builds, ai-review) to pass.
+5. **Bootstrap staging data via Airflow** (no prod dump — staging populates
+   itself from source, exercising the pipeline image end-to-end):
+   - Open the staging Airflow UI (`http://<host>:8081`) and trigger, in order:
+     `school_data_daily`, `school_data_monthly_ofsted`,
+     `school_data_monthly_parent_view`, then the manual-schedule
+     `school_data_annual_ees` and `school_data_annual_idaci`.
+   - First runs download from government sources (GIAS, Ofsted, EES, IDACI),
+     run dbt, and sync Typesense — expect the initial backfill to take a while.
+   - The scheduled DAGs then keep staging fresh exactly like prod.
+6. **Switch the prod stack to `:prod` tags** — the repo's
+   `docker-compose.portainer.yml` is already updated; redeploy the prod stack
+   from it. Until the first pipeline run promotes an image, tag the current
+   images manually: `docker buildx imagetools create -t <image>:prod <image>:latest`
+   for each of the three images.
+
+## Rollback
+
+Every promotion first re-points `:prod-previous` at the outgoing `:prod`.
+To roll back:
+
+```bash
+for img in backend frontend pipeline; do
+  docker buildx imagetools create \
+    -t privaterepo.sitaru.org/tudor/school_compare-$img:prod \
+    privaterepo.sitaru.org/tudor/school_compare-$img:prod-previous
+done
+curl -fsSk -X POST "$PORTAINER_PROD_WEBHOOK"
+```
+
+Or promote any older build directly: `imagetools create -t <image>:prod <image>:sha-<shortsha>`.
+
+## E2E suite
+
+Lives in `e2e/` (own package — CI installs it without the app's node_modules).
+Journeys: home + name search, postcode search, school detail, two-school
+comparison, rankings table. Run locally against any environment:
+
+```bash
+cd e2e && npm ci
+BASE_URL=http://10.0.1.151:3000 npx playwright test
+```
+
+Tests assert data invariants (results exist, charts render), not exact
+numbers, so scheduled data refreshes don't break the gate.
+
+## AI code review
+
+`scripts/ci/ai_review.py` sends the PR diff to Claude (`claude-opus-4-8`),
+posts the structured findings as a PR comment, and fails the check only when a
+finding is rated **severe** (would break prod, leak data, or corrupt data).
+Minor findings are informational and never block a merge.

+"""AI code review for Gitea pull requests.
+
+Reads the PR diff (base branch vs HEAD), asks Claude to review it, posts the
+findings as a PR comment via the Gitea API, and exits non-zero only when the
+review contains at least one severe finding — so the job can gate merges
+without blocking on nitpicks.
+
+Required environment:
+    ANTHROPIC_API_KEY   Anthropic API key
+    GITEA_TOKEN         Gitea token with permission to comment on PRs
+    GITEA_SERVER_URL    e.g. https://privaterepo.sitaru.org
+    GITEA_REPOSITORY    owner/repo
+    PR_NUMBER           pull request index
+    BASE_REF            base branch name (e.g. main)
