- Base URL corrected to https://www.fuel-finder.service.gov.uk (the
api.fuelfinder.service.gov.uk host in the portal's examples is stale —
it does not resolve; www.fuel-finder... resolves to CloudFront and is
what the live spec uses). Verified: /health now reports source=api,
8,010 stations, 0 failures.
- Fuel Finder is strictly sequential (30 rpm per client, 429 on overlap):
added FUEL_API_BATCH_SLEEP (default 4.0s) between pages ≈ 15 rpm.
- Stale-cache refresh moved off the request path into a background
thread — a multi-minute rate-limited sync no longer blows the app's
5s timeout; stale data is served while it catches up.
- Multiple diesel variants (B7_STANDARD, B7_PREMIUM, B10) now map to
DIESEL as the MINIMUM price, so a premium price can't inflate the
cheapest-diesel reference (CSV relay took first-wins; min is safer).
- Added B7_PREMIUM (underscore) to the fuel map — official key.
- scripts/run.sh now prefers the project venv (bare python3 missed
uvicorn when run outside an activated env).
- Tests updated for min-diesel + B7_PREMIUM; 12/12 pass.
