Refs ingest

refs-ingest

Add a 行前預習 reference into a trip PWA. These are the videos and articles a parent watches the night before — the "今晚先看" card under each day.

Each ref lands in refs.json under schedule_refs[<day>]; render.js reads refs.schedule_refs[activeDayId] to fill the collapsible. So a ref is bound to a day (its context), not a clock time.

Steps

1. Get the URL. The user gives a YouTube / Vimeo / blog / Reel link. For YouTube, refs-ingest fetches the title automatically via oEmbed (no API key). For a blog or when oEmbed is unavailable, pass --title (use /browse to read the page title first).

2. Run the engine with the URL + the day it preps:

   bun skills/refs-ingest/refs-ingest.ts --out <trip-dir> \
     --url <link> --day day_2 [--title "..."] [--lang zh-tw] \
     [--kid-friendly true] [--duration-min 6] [--summary "<1-line>"]
   

   --day (or batch context) is always required: the current renderer shows only schedule_refs[activeDayId], so a synthetic general bucket would be invisible. For a trip-wide article, choose one primary preparation day and explain its scope in summary; other days need distinct, day-specific sources because duplicate URLs are forbidden across schedule refs.

3. Report which day the ref was added to (or that it was skipped as a dup).

Entry shape (matches Tokyo refs.json)

{
  "type": "youtube|vimeo|reel|article",   // inferred from the URL host
  "title": "...",                          // --title or YouTube oEmbed
  "url": "https://...",                    // http(s) only; other schemes rejected
  "source": "...",                         // oEmbed author or the URL host
  "lang": "zh-tw",
  "context": "day_2",                      // the real day it preps
  "duration_min": 6,                       // optional
  "kid_friendly": true,
  "summary": "..."                         // optional, shown on the prep card
}

Batch (--batch)

bun skills/refs-ingest/refs-ingest.ts --out <trip-dir> --batch refs.json
# refs.json = [{ "url": "...", "day": "day_2", "title": "...", "summary": "..." }, ...]

Reads refs.json once, appends all, writes once, regenerates the service worker once. Slow YouTube metadata is fetched with bounded concurrency before the trip-wide write lock; mutable trip data is then re-read under the lock. Duplicate URLs (across all days) are skipped. Batch mode is intentionally partial: an item with a missing/unknown day, bad URL, bad duration, duplicate URL, or unavailable title is counted as skipped while valid siblings are committed, and the command exits 0 if the write/SW reconciliation succeeds. Schema-invalid batch input exits 2 before any write. A malformed existing refs.json is never overwritten — the engine refuses and tells you to fix it.

Note on dup-ref invariant

launch-check enforces that schedule_refs URLs are unique across the trip (inline prep_refs on contingency alternatives are exempt, mirroring Tokyo's R11′ rule). refs-ingest's per-URL dedup keeps schedule_refs clean on ingest; launch-check is the final gate.
