… OpenAI timeout The /api/chat/* and /api/osm/* endpoints called OpenAI / Overpass with no auth, no rate limit, no input validation, and no body-size cap — anyone could run up the OpenAI bill, use us as a free proxy, or OOM the server with a huge payload. - express-rate-limit (40/min/IP) on /api/chat and /api/osm - zod-validate /api/chat/query (string ≤500 chars + optional bbox tuple); cap index-assets (≤5000), index-geojson features (≤20000), overpass query length (≤10k) - express.json/urlencoded limit 1mb - OpenAI client timeout 15s + maxRetries 2 (a hung call can't block the server) - health check no longer leaks OPENAI_API_KEY presence - .gitignore .env* Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…, bigger embed batch - generateSummary: gpt-4o → gpt-4o-mini (~50× cheaper, fast; summary is short prose) - compression() middleware → the ~1.9MB GeoJSON ships gzipped (~200-300KB) - express.static maxAge 1d → repeat visits don't re-download the static assets/GeoJSON - osmService: load the 6 risk-zone files in parallel (Promise.all) instead of sequentially - embedding batch 50 → 500 (far fewer OpenAI round-trips → faster startup indexing) Deferred (needs a persistent vector store to be reliable on Replit cold starts, so not a low-risk one-liner): persisting embeddings so the server doesn't re-embed on every boot. Mitigated here by the larger batch size. Tracked as a follow-up. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- cosineSimilarity: guard against zero-magnitude vectors (return 0, not NaN) - bboxToH3Cells: reject inverted/degenerate bbox (was silently returning an empty filter that behaves like "no spatial filter") - delete dead code left after the chat refactor: mapActionSchema, enhanceMapActionWithCoordinates, enhanceResponseWithGeography - strip 45 standalone console.log statements across aiChat.ts, MapView.tsx, osmService.ts (kept console.error / console.warn) - remove unused deps: overpass-ts, h3-js (never imported) No behavior change beyond the two guards. Deferred shared/config.ts (centralizing the duplicated PoA bbox/center) — it touches many files, so it belongs in its own pass, not this low-risk batch.

…sets state - AIChatBox: clickable example-prompt chips below the welcome message (auto-send) so users discover what the assistant can do without typing. Refactored handleSendMessage to accept an explicit prompt (and fixed the Send button passing the click event as the query). - Footer: "⚠ Prototype — for exploration only, not for emergency or critical decisions." disclaimer (important framing for a risk tool). - AssetsTab: when zero assets actually loaded (OSM service down → proxy returns []), show "No critical assets loaded — data service may be unavailable" + Retry, instead of the misleading "no assets match your filters". Client-only, low-risk; npm run build passes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Small, client-only UX improvements (the bigger UX items — PT-BR i18n, mobile, color-blind-safe risk encoding — were deferred to their own passes).
