fix(sync): stop the catalog sync re-embedding vectors it already had - #1141
Conversation
- New shows get their newest 5 episodes embedded first; the rest of the window follows after 7 days on the charts (most leave before then). - The nightly trim fails closed when its cap lookup fails, and shows keep the highest cap they earned while their vectors are kept. - Stage 3 never hands stage 4 a one-item fallback list, and stage 4 only prunes against a full window. - Vectors whose upload failed are spooled to disk and uploaded first by the next run. - turso.text() binds catalog keys as text; remediation uses per-show caps.

Explanation
The title follows the required Conventional Commits format, uses the allowed
fixtype, uses thesyncscope, uses imperative wording, stays under 72 characters, and accurately describes the main change.
Full details: Architecture Compliance
-
Explanation
No architecture violation is introduced. The authoritative diff changes only
.gitignore,scripts/README.md,scripts/package.json, and Node.js catalog-sync files underscripts/sync; it changes no Android modules, Kotlin/Java sources, Gradle dependencies, or app composition code. The added imports are limited to local sync helpers and Node built-ins. No added code references PostHog, Hilt, Koin, Dagger, MockK,PlaybackRepository, orAppContainer, and no documented Android identity/storage contract is renamed or recreated.
Full details: Module Readme Updated
-
Explanation
The pull request changes 17 files, all under scripts/ or .gitignore. It changes no Kotlin file under app/src/main/, core/<module>/src/main/, or feature/<module>/src/main/. The module README requirement is therefore not triggered. scripts/README.md is also modified.
Full details: Jvm Tests For Changed Logic
-
Explanation
PASS: The PR changes Node.js catalog-sync code under
scripts/sync, not JVM engines, repositories, ViewModels, or helpers under the Androidsrc/maintree. It adds hermetic JavaScript regression tests alongside the changed sync logic. The JVM-test requirement undersrc/testis therefore not applicable.

- Line 76: Update the spool tests around vectorSpool.spool and
vectorSpool.replay: spool into a new nested directory beneath the temporary

the malformed file at the default time before testing expiration, then create a

remediate-qdrant.js referenced the trimmed show list removed with its local trim loop, so a dry or live run failed after step 5. The cap trim now returns the trimmed show IDs. Stage 4 clears a show's depth date only after its re-flag is written, the vector spool folder no longer depends on the working directory, and the spool tests check what they name.

Summary
Stops the catalog sync from deleting and then re-embedding vectors it already had, and stops new chart shows from costing a full window of embeddings straight away.
Motivation
The sync embeds about 50k episodes a day while the vector store stays flat, so most of that work redoes earlier work. The largest share is chart churn: shows join the charts, get their whole window embedded, and are deleted again a week after they leave. Several code paths also delete vectors that are later re-embedded.
What changed
lib/vector-window.js, stage 4). A show with no vectors gets its newestNEW_ENTRANT_EPISODES(5) embedded. Its depth date (shows[id].din the sync state) is setNEW_ENTRANT_DEPTH_DAYS(7) ahead. When that date passes, stage 4 flags the show once for its full window. Shows that left the charts by then never get it.lib/episode-caps.js). A show keeps the highest cap it had while its vectors are kept (shows[id].k). The sync state entry is deleted together with the show, so the cap lasts exactly as long as the vectors. A US/GB show that leaves those charts no longer loses 30 vectors.lib/trim-episode-caps.js). If the chart cap lookup fails, nothing is trimmed; before, every show fell back to 20. The trim andremediate-qdrant.jsboth use the larger of the chart cap and the earned cap. Remediation no longer uses the old blanket 50.handoffList). When the full fetch comes back empty, stage 4 fetches the list itself instead of receiving the one-item tip.pruneIsSafe).lib/vector-spool.js). A batch whose upsert fails is written toSYNC_SPOOL_DIR(defaultscripts/data/vector-spool/, gitignored). The next stage 4 uploads it before embedding anything, so its existence checks see those points. Batches older than 7 days are dropped.lib/turso.js).turso.text(value)binds a value as TEXT even when it's all digits, so a catalog key like00123stays00123. The integer default is unchanged.prune skipped,newest-first,depth,spooledandreplayed.Behavior & compatibility
