Staging health polling asked only whether something answered HTTP 200 at the base URL. It could not tell the new deployment from the old one, so journeys could pass against the previous release, and concurrent merges could move the staging tags underneath a run in flight. Each staging run now mints a build ID and stamps all three images with the commit and that ID, as labels and — for frontend and backend — as a build-time JSON file that environment overrides cannot rewrite. /release.json reports both identities uncached, and scripts/ci/release.py polls for the expected pair before and after the journeys. Only then are the captured build digests tagged verified-<sha>. Promotion resolves those verified tags to immutable digests, revalidates their labels, and refuses a mixed or incomplete set before any :prod tag moves. The whole staging workflow shares one concurrency group with cancellation disabled, so releases serialise. The scripts are stdlib-only and unit-tested against mocked registry and HTTP behaviour; PR checks now run the pipeline and CI suites too. The runbook records what this cannot prove locally, and that the first rollout needs a commit built by this workflow. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
SchoolCompare
SchoolCompare compares schools across England: primary (KS2), secondary (KS4), all-through and post-16 provision, with coverage depending on the source dataset. It provides school search, postcode maps, comparisons, rankings, place pages, Ofsted information, admissions and destination measures. Editorial content lives in a Payload CMS blog.

Runtime
The public site is Next.js, not the FastAPI root page. Browser /api/*
requests pass through a Next.js route handler to FastAPI. Server-rendered pages
call FastAPI directly using FASTAPI_URL, including its /api suffix.
PostgreSQL/PostGIS stores school data. Meltano/Singer extracts source data;
dbt builds marts.*; FastAPI reads those tables. Typesense serves text search
and autocomplete. Payload runs inside Next.js and owns a separate payload
database schema and uploaded media.
There is no automatic CSV import or sample dataset on startup. A working school-data environment needs populated marts from the pipeline or an approved database snapshot. See development before choosing a setup.
Validation
cd nextjs-app
npm ci
npm run typecheck
npm test -- --runInBand
Backend checks, pipeline validation, runtime versions and E2E requirements are
listed in DEVELOPMENT.md. No npm run lint script is
currently defined.
Deployment
Work on a feature branch and open a PR. Merging to main builds images and
deploys staging. Production promotion is a separate, human-triggered Gitea
workflow. Use DEPLOY.md and the Portainer compose files as the
operational references. The generic compose examples still reference :latest,
which the current release workflow does not publish.
