TudorandClaude Opus 5	0fa1a292c7	fix(api): bound what a forged CF-Connecting-IP can buy ... Code review, both findings valid. The design doc claimed Cloudflare "replaces the header, so a browser cannot forge it", and that only the X-Forwarded-For fallback was forgeable. That is true only for traffic that actually passed through Cloudflare, and nothing in this process can verify that it did. Reaching the origin directly, both headers are equally attacker-controlled — and rotating CF-Connecting-IP mints a fresh rate-limit bucket per request, defeating per-client limits on every endpoint including the DataFrame-heavy /api/schools. Against abuse that is worse than the shared bucket it replaced, which at least capped everyone together. So the ceiling comes back. I dropped it earlier arguing it belonged at Cloudflare; that argument assumed the keying was sound, and it is not. GlobalRateLimitMiddleware counts all /api/ traffic in a fixed window against a total, independent of client identity, outermost so it refuses before any work happens. Written by hand because slowapi cannot express a global cap: default_limits and application_limits are both keyed by key_func, and the latter needs middleware this app does not install. It does not make the header trustworthy — it makes trusting it survivable. The real fix is Authenticated Origin Pulls or an origin firewall, now documented in DEPLOY.md as the open gap it is. 127.0.0.1 is exempt: the healthcheck curls localhost from inside the container, and starving it would restart the container and turn a load spike into an outage loop. Keyed on the peer address, never the Host header, which the caller sets. Second finding: suggest_schools_typesense promised "never raises" while the parsing loop sat outside the try, so int(None) on a malformed document would have made a keystroke a 500. The loop now skips bad rows rather than dropping the whole list — and a hit with no document no longer becomes a suggestion pointing at /school/0.

TudorandClaude Opus 5	6e0a278340	docs(suggest): implementation plan, eight tasks ... Self-review caught three defects in the plan. .omniBoxContainer, the wrapper the dropdown positions against, does not declare position: relative — without it the list anchors to the page. The postcode suppression test typed character by character, so it would have asserted no request while 'NW1' legitimately fires one; it now sets the value in one go. And the Enter-submits-search assertion needed waitFor, because updateURL pushes inside startTransition. Task 1 is the one to review hardest: it is the only unflagged change and it alters rate limiting for every endpoint.
