Answer fetches run with concurrency 15; external API calls (statement conversion, emojis) are capped per run and fall back gracefully — caches fill up across runs.\n- **logic.ts** — the build pipeline: `getExpectedDate` handles both bucket-style and cumulative threshold-style markets; `convertQuestionInternally` handles common \"When will X…?\" phrasings via regex before falling back to an external LLM conversion API.\n- **cache.ts** — SQLite (per-val DB) caches for question→statement conversions and statement→emojis.\n- **index.ts** — HTTP val. Serves the React client, `/api/timeline-events` (cached JSON from blob, instant), and `/source`.\n- **styles.ts** — CSS exported as a string.\n- **moi.md / images.md** — build.moi directory metadata.\n\n## Why the cron?\n\nThe timeline build takes ~90s (400+ markets, one answers request each, plus external APIs) — far past the HTTP request time limit. Previously the build ran per-request over SSE and got killed mid-stream. Now the HTTP endpoint just reads the pre-built blob.\n\n## External dependencies\n\n- Manifold API (`/v0/search-markets?contractType=DATE`, `/v0/market/:id/answers`)\n- `texttoemojis.val.run` — emoji tagging (dcm31's val)\n- Question→statement conversion API (dcm31's val)\n\n## Manual rebuild\n\nRun `build.ts` from the Val Town UI, or call `buildAndStore()` from a script.\n",[],[129],["D",1783477323676],[],[19],"5cbdcc4a-6964-11f0-9ae6-0224a6c84d84",["D",1753454022202],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","a timeline of
