read stored draws\"]\n```\n\n## Files\n\n| File | Type | Purpose |\n|--------------|----------|---------|\n| `scraper.ts` | interval | Cron entrypoint. Runs every 15 min, scrapes the most recent 4 draws. |\n| `ticks.ts` | script | Converts dates ⇄ .NET \"ticks\" and figures out recent Tue/Fri draw dates. |\n| `parse.ts` | script | Fetches the API and unwraps the XML-wrapped JSON payload. |\n| `db.ts` | script | SQLite schema + upsert (keyed on `play_date_ticks`). |\n| `viewer.ts` | http | `GET /` → latest 20 draws as JSON. `GET /?ticks=` → full raw payload. |\n\n## Notes\n\n- **The API returns XML-wrapped JSON.** `parse.ts` strips the `…`\n wrapper and decodes HTML entities before `JSON.parse`.\n- **`.NET` ticks exceed JS's safe integer range,** so they're handled with `BigInt`\n and stored/queried as TEXT. Storing them as INTEGER causes a libSQL\n \"integer too large\" error.\n- **Cron runs in UTC.** Draw dates are computed on a UTC date basis.\n- The scraper re-scrapes the latest few draws each run (upsert), so jackpot\n amounts and winner counts stay fresh as they're finalized after each draw.\n\n## Changing the schedule\n\nEdit the interval on `scraper.ts`. Current: `*/15 * * * *` (every 15 min).\nFor hourly use `0 * * * *`.\n",[163],"pulls","branches",1,"forks","envVars",{"_177":42,"_179":42},"connections",{"_177":42,"_178":42},"count","unfilledCount","emptyCount",{"_18":162,"_20":163,"_117":164,"_118":-5,"_119":71,"_120":165,"_121":38,"_22":202,"_68":42,"_124":98,"_126":167,"_128":26,"_129":-5,"_187":203,"_88":204},{"_18":154,"_20":155,"_117":156,"_118":-5,"_119":71,"_120":157,"_121":38,"_22":199,"_68":159,"_124":136,"_126":160,"_128":26,"_129":-5,"_187":200,"_88":201},{"_18":147,"_20":148,"_117":149,"_118":-5,"_119":71,"_120":150,"_121":38,"_22":196,"_68":123,"_124":136,"_126":152,"_128":26,"_129":-5,"_187":197,"_88":198},{"_18":139,"_20":140,"_117":141,"_118":-5,"_119":71,"_120":142,"_121":38,"_22":193,"_68":42,"_124":144,"_126":145,"_128":26,"_129":-5,"_187":194,"_88":195},{"_18":131,"_20":132,"_117":133,"_118":-5,"_119":71,"_120":134,"_121":38,"_22":190,"_68":123,"_124":136,"_126":137,"_128":26,"_129":-5,"_187":191,"_88":192},{"_18":115,"_20":116,"_117":36,"_118":-5,"_119":71,"_120":69,"_121":38,"_22":186,"_68":123,"_124":125,"_126":127,"_128":26,"_129":-5,"_187":188,"_88":189},["D",1781114824843],"children",[],[116],["D",1781114381293],[],[132],["D",1781114347627],[],[140],["D",1781114384554],[],[148],["D",1781114372121],[],[155],["D",1781114405362],[],[163],["D",1781114312383],["D",1789499469860],{"_16":17,"_86":81},{"_16":17,"_80":81,"_82":81,"_33":34,"_83":84,"_85":26},{"_68":69,"_20":70,"_18":71,"_72":19,"_73":-5,"_74":-5,"_75":-5,"_76":-5,"_77":-5,"_78":21,"_79":17},"ctx",{"_61":-5,"_106":243,"_244":245,"_246":247,"_248":26,"_249":26,"_250":26,"_251":38,"_252":-5,"_253":-7,"_254":-7,"_255":42,"_256":26,"_257":26,"_258":-5,"_259":26,"_260":26,"_261":26,"_262":-5},"ENV",{"_214":215,"_216":217,"_218":70,"_219":220,"_221":222,"_223":224,"_225":226,"_227":228,"_229":230,"_231":232,"_233":234,"_235":236,"_237":238,"_239":240,"_241":242},"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"]
