The README still opened on "Primary School Compass", a KS2 tool for Wandsworth
and Merton served by FastAPI and vanilla JavaScript with Chart.js. Every layer
of that sentence is now wrong: coverage is England-wide across KS2, KS4,
all-through and post-16, Next.js owns the public UI, and school data comes from
dbt-built `marts.*` rather than CSVs loaded at startup. The setup instructions
walked a reader into a virtualenv and a CSV import that cannot build the current
schema, so following the docs produced an empty database and a wrong mental
model at the same time.
Replace the narrative docs with two reference documents that were checked
against the code: docs/ARCHITECTURE.md for request flow, data ownership, the
backend/frontend module boundaries and the real publication sequence, and
docs/DEVELOPMENT.md for the checks that actually run, including the container
and CI version skew that makes "just run pytest" misleading.
The env examples drifted the same way. ALLOWED_ORIGINS is a JSON array, not a
comma-separated list; the frontend needs FASTAPI_URL, DATABASE_URL and
PAYLOAD_SECRET, none of which were documented; and RATE_LIMIT_BURST,
DEFAULT_PAGE_SIZE and MAX_PAGE_SIZE were presented as tuning controls the routes
do not consult. Each is now stated as it behaves.
MIGRATION_SUMMARY.md keeps its content but gains a banner, because it reads like
setup instructions and is not.
