Second failure of the same assertion, and the first fix addressed a real but different problem. This is the one that was actually producing the number. The arrows scroll with `behavior: 'smooth'`. The test polled for "has it moved at all" — satisfied 50ms in, at 13px of a 1300px journey — then recorded the offset, clicked, and recorded again. The row was still travelling throughout, so the delta it measured was the tail of the arrow's animation, not the effect of the selection. Hence a deterministic 659, roughly half of the 1317 this school's row scrolls. Measured against staging rather than reasoned about: the animation runs about 700ms, and the samples are in the helper's comment. settledScrollLeft waits for two identical readings before trusting one. The app was never at fault — driving staging by hand, the offset holds at 1317 across the selection, exactly as intended. Verified against staging both ways: main's version of this test fails there, this version passes, along with all three mobile widths. 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.
