Three schools is not a neighbourhood in inner London, so the cap is six with three visible and arrows for the rest. Raising the cap exposes something the old cap hid. Tiers exist to reach a usable set, and with six slots a naive loop would keep widening to fill them — dragging in tier-3 schools ten miles away to sit beside three good matches that had already earned the row. So tiers now stop relaxing once three are found, and the remaining slots are filled only from the tiers already used. Four tier-1 matches never open tier 2. The carousel scrolls a list rather than swapping a view: all six cards are in the initial HTML, so every link stays crawlable and the row still scrolls with JavaScript off. The arrows' edge test carries an 8px tolerance because the scroller's focus-ring padding is the first snap position — a row at rest reports scrollLeft 2, and an exact test for 0 left the back arrow live and pointing nowhere.

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.
