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",[200],"d0bb8b9f-ee74-4a4c-a1ed-21198bcbe114","scripts","5aab5590-b420-4b84-9a53-d67c154cfd07",25,["D",1783477323676],"directory",[207],"pulls","branches",6,"envVars",{"_220":22,"_222":22},"connections",{"_220":22,"_221":22},"count","unfilledCount","emptyCount",{"_27":206,"_13":207,"_138":208,"_140":-5,"_141":91,"_142":209,"_144":46,"_47":257,"_88":22,"_147":211,"_149":-5,"_151":20,"_152":-5,"_233":258,"_104":259},{"_27":199,"_13":200,"_138":201,"_140":-5,"_141":91,"_142":202,"_144":46,"_47":254,"_88":24,"_147":116,"_149":204,"_151":20,"_152":-5,"_233":255,"_104":256},{"_27":191,"_13":192,"_138":193,"_140":-5,"_141":91,"_142":194,"_144":46,"_47":251,"_88":22,"_147":196,"_149":197,"_151":20,"_152":-5,"_233":252,"_104":253},{"_27":184,"_13":185,"_138":186,"_140":-5,"_141":91,"_142":187,"_144":46,"_47":248,"_88":24,"_147":148,"_149":189,"_151":20,"_152":-5,"_233":249,"_104":250},{"_27":177,"_13":178,"_138":179,"_140":-5,"_141":91,"_142":180,"_144":46,"_47":245,"_88":24,"_147":116,"_149":182,"_151":20,"_152":-5,"_233":246,"_104":247},{"_27":170,"_13":171,"_138":64,"_140":-5,"_141":91,"_142":89,"_144":46,"_47":242,"_88":173,"_147":174,"_149":175,"_151":20,"_152":14,"_233":243,"_104":244},{"_27":162,"_13":163,"_138":164,"_140":-5,"_141":91,"_142":165,"_144":46,"_47":239,"_88":167,"_147":148,"_149":168,"_151":20,"_152":-5,"_233":240,"_104":241},{"_27":154,"_13":155,"_138":156,"_140":-5,"_141":91,"_142":157,"_144":46,"_47":236,"_88":159,"_147":116,"_149":160,"_151":20,"_152":-5,"_233":237,"_104":238},{"_27":136,"_13":137,"_138":139,"_140":-5,"_141":91,"_142":143,"_144":46,"_47":232,"_88":146,"_147":148,"_149":150,"_151":20,"_152":-5,"_233":234,"_104":235},["D",1783480155248],"children",[],[137],["D",1753498183371],[],[155],["D",1783476410072],[],[163],["D",1784124994783],[],[171],["D",1753498170080],[],[178],["D",1783476356302],[],[185],["D",1783476418585],[],[192],["D",1783480256927],[],[200],["D",1783477323676],[],[207],["D",1753454022202],["D",1789527031073],{"_11":12,"_57":101},{"_11":12,"_51":100,"_52":101,"_34":63,"_54":102,"_56":20},{"_88":89,"_13":90,"_27":91,"_92":58,"_93":-5,"_94":-5,"_95":-5,"_96":-5,"_97":-5,"_98":14,"_99":12},"ctx",{"_39":-5,"_124":298,"_299":300,"_301":302,"_303":20,"_304":20,"_305":20,"_306":46,"_307":-5,"_308":-7,"_309":-7,"_310":22,"_311":20,"_312":20,"_313":-5,"_314":20,"_315":20,"_316":20,"_317":-5},"ENV",{"_269":270,"_271":272,"_273":90,"_274":275,"_276":277,"_278":279,"_280":281,"_282":283,"_284":285,"_286":287,"_288":289,"_290":291,"_292":293,"_294":295,"_296":297},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
