A failure logs to the console,\nrecords the attempt, sends a Telegram error report, and **returns cleanly** — so\nthe next scheduled run still fires.\n\n## Files\n\n| File | Role |\n| --- | --- |\n| `main.ts` | The interval handler + pipeline orchestration |\n| `lib/config.ts` | Tunables: `MAX_ATTEMPTS`, `SEARCH_QUERIES` |\n| `lib/env.ts` | Env var names, required-key preflight |\n| `lib/db.ts` | SQLite schema, migrations, retry bookkeeping |\n| `lib/youtube.ts` | Step 1 — trending video discovery |\n| `lib/opus.ts` | Step 2 — AI clipping |\n| `lib/tiktok.ts` | Step 3 — token refresh + direct publishing |\n| `lib/telegram.ts` | Notifications (never throws) |\n| `scripts/smoke-test.ts` | Exercises the SQLite layer; safe to run anytime |\n\n## Environment variables\n\n| Key | Required? | Where to get it |\n| --- | --- | --- |\n| `YOUTUBE_API_KEY` | yes | Google Cloud Console → enable **YouTube Data API v3** → API key |\n| `OPUS_CLIP_API_KEY` | yes | Opus Clip account / API access |\n| `TELEGRAM_BOT_TOKEN` | yes | [@BotFather](https://t.me/BotFather) |\n| `TELEGRAM_CHAT_ID` | yes | Your chat/channel id — message the bot first, then read `getUpdates` |\n| `TIKTOK_CLIENT_KEY` | for auto-refresh | TikTok for Developers → your app's client key |\n| `TIKTOK_CLIENT_SECRET` | for auto-refresh | TikTok for Developers → your app's client secret |\n| `TIKTOK_REFRESH_TOKEN` | for auto-refresh | From the OAuth flow (scope `video.publish`) — the seed for rotation |\n| `TIKTOK_ACCESS_TOKEN` | alternative | A short-lived token, if you'd rather paste one by hand |\n\nThe job skips itself and warns you if anything required is missing.\n\n## TikTok token renewal\n\nTikTok access tokens expire in ~24 hours, which is shorter than the gap between\nruns — a static token would be dead by the second run. `lib/tiktok.ts` handles\nthis:\n\n1. It caches the token pair in **blob storage** (`tiktok:tokens`).\n2. If the cached access token is still good, it uses it.\n3. Otherwise it exchanges the refresh token at\n `https://open.tiktokapis.com/v2/oauth/token/`. TikTok **rotates** the refresh\n token on every exchange, so the new pair is written straight back to blob\n storage. `TIKTOK_REFRESH_TOKEN` is only the initial seed.\n4. If refresh fails and a static `TIKTOK_ACCESS_TOKEN` exists, it falls back to\n that rather than failing the run.\n\nSet the three `TIKTOK_CLIENT_*` / `TIKTOK_REFRESH_TOKEN` keys to enable this. If\nyou only set `TIKTOK_ACCESS_TOKEN`, the val still works — you'll just have to\npaste a fresh token before it expires.\n\n## Retry budget\n\nThe table tracks how each video went, so one bad video can't block the pipeline\nforever:\n\n```sql\nCREATE TABLE IF NOT EXISTS processed_trending_videos (\n video_id TEXT PRIMARY KEY,\n processed_at DATETIME NOT NULL,\n status TEXT NOT NULL DEFAULT 'pending', -- 'posted' | 'failed'\n attempts INTEGER NOT NULL DEFAULT 0,\n last_error TEXT\n);\n```\n\n- `status = 'posted'` → never retried.\n- `status = 'failed'` → retried until `attempts` reaches `MAX_ATTEMPTS`\n (default **3**, so ≈36 hours of retrying at one run per 12h), then skipped.\n\nThe first two columns are the original schema; the other three are added by an\nidempotent `ALTER TABLE` migration on startup, so an existing table upgrades\nitself.\n\nTune the budget in `lib/config.ts`. To give a parked video another chance, call\n`forgetProcessed(videoId)` — or just delete the row.\n\n## Things to know before you turn it on\n\nThese are real constraints of the third-party APIs, not bugs in this val.\n\n1. **The Opus Clip endpoint is not a documented public API.** `POST\n https://api.opus.pro/v1/clips` follows the commonly-referenced contract, but\n Opus Clip does not publish a stable spec. `lib/opus.ts` is written to be\n forgiving — it walks the response for the first plausible clip URL, caption\n and hashtags, and polls for up to 5 minutes if the render is async — but if\n your account's contract differs you may need to adjust `createBody()` and the\n `*_KEYS` lists. Everything else in the pipeline stays the same.\n2. **TikTok `PULL_FROM_URL` requires a verified domain.** TikTok fetches the\n clip from the URL Opus returns, so that host must be registered as a verified\n URL property in your TikTok developer app. If it isn't, the post is rejected.\n3. **`PUBLIC_TO_EVERYONE` requires an audited app.** Until your TikTok app\n passes audit, TikTok forces `SELF_ONLY` and rejects public posts.\n4. **YouTube quota.** `search.list` costs 100 units; the default daily quota is\n 10,000. With 4 queries × 2 runs/day that's 800 units/day — comfortable, but\n don't add dozens of keywords.\n5. **Opus Clip renders can outlast a run.** Polling gives up after 5 minutes; if\n the render is slower, that run records a failure and the next one retries.\n\n## Verifying\n\n- Run [scripts/smoke-test.ts](url:scripts/smoke-test.ts) to check the SQLite\n layer, the retry bookkeeping and the cleanup. It leaves the database untouched.\n- Run [main.ts](url:main.ts) manually from the editor to exercise the full\n pipeline without waiting for the cron.",[151],"4ab75f96-c9b6-4b0e-ad07-f09c2f292158","scripts","68926185-0dcc-4025-b344-11069b51005e",10,true,["D",1789590732153],"directory",[159],"3552ec96-097b-43ff-a276-c539b5fd3f15","lib","49f6b9da-c744-4653-8d32-c1d1321abcb4",["D",1789590686836],[167],"pulls","branches","forks","envVars",{"_178":180,"_181":68},"connections",{"_178":68,"_179":68},"count","unfilledCount",4,"emptyCount",{"_50":166,"_38":167,"_36":168,"_141":-5,"_48":49,"_47":145,"_143":162,"_45":265,"_13":68,"_40":164,"_42":-5,"_30":31,"_148":-5,"_195":266,"_33":267},{"_50":257,"_38":258,"_36":259,"_141":168,"_48":49,"_47":260,"_143":31,"_45":261,"_13":155,"_40":41,"_42":262,"_30":31,"_148":-5,"_195":263,"_33":264},{"_50":248,"_38":249,"_36":250,"_141":168,"_48":49,"_47":251,"_143":162,"_45":252,"_13":253,"_40":41,"_42":254,"_30":31,"_148":-5,"_195":255,"_33":256},{"_50":240,"_38":241,"_36":242,"_141":168,"_48":49,"_47":243,"_143":31,"_45":244,"_13":145,"_40":41,"_42":245,"_30":31,"_148":-5,"_195":246,"_33":247},{"_50":232,"_38":233,"_36":234,"_141":168,"_48":49,"_47":235,"_143":162,"_45":236,"_13":68,"_40":41,"_42":237,"_30":31,"_148":-5,"_195":238,"_33":239},{"_50":224,"_38":225,"_36":226,"_141":168,"_48":49,"_47":227,"_143":31,"_45":228,"_13":68,"_40":41,"_42":229,"_30":31,"_148":-5,"_195":230,"_33":231},{"_50":220,"_38":39,"_36":37,"_141":168,"_48":49,"_47":14,"_143":162,"_45":221,"_13":145,"_40":41,"_42":44,"_30":31,"_148":-5,"_195":222,"_33":223},{"_50":212,"_38":213,"_36":214,"_141":168,"_48":49,"_47":215,"_143":162,"_45":216,"_13":145,"_40":41,"_42":217,"_30":31,"_148":-5,"_195":218,"_33":219},{"_50":158,"_38":159,"_36":160,"_141":-5,"_48":49,"_47":161,"_143":162,"_45":209,"_13":68,"_40":164,"_42":-5,"_30":31,"_148":-5,"_195":210,"_33":211},{"_50":201,"_38":202,"_36":203,"_141":160,"_48":49,"_47":204,"_143":162,"_45":205,"_13":155,"_40":41,"_42":206,"_30":31,"_148":-5,"_195":207,"_33":208},{"_50":150,"_38":151,"_36":152,"_141":-5,"_48":49,"_47":153,"_143":31,"_45":198,"_13":155,"_40":26,"_42":156,"_30":31,"_148":-5,"_195":199,"_33":200},{"_50":138,"_38":139,"_36":140,"_141":-5,"_48":49,"_47":142,"_143":31,"_45":194,"_13":145,"_40":146,"_42":147,"_30":31,"_148":-5,"_195":196,"_33":197},["D",1789591068476],"children",[],[139],["D",1789591092156],[],[151],"23ccbaff-0072-458e-b39f-ee8a2924dfb8","smoke-test.ts","b2591bee-b20d-11f1-a33b-1607ee4eb77e",21,["D",1789591076786],"/**\n * Smoke test for the SQLite layer.\n *\n * Run this from the val editor before the first scheduled run (or any time you\n * change `lib/db.ts`) to confirm the schema, the retry bookkeeping and the\n * cleanup all behave.
