…tion Backend: - Add taste_state table (migration 0016 + journal entry) syncing adaptive priorities, recommendation preferences, and listening events per profile with last-writer-wins semantics - New collaborative layer: privacy-safe 'Listeners like you' shelf built from taste-neighbor favorites; community counts give a bounded boost across search ordering, radio, and home ranking - Smart Mix sequences queues for mood flow after diversity-aware build - Adaptive skip learning matches Android parity (early skip < 30s or half, double weight), discovery wins boost unfamiliar artists you come to like - Time-aware mixes, On Repeat, Fresh Finds home shelves; dislike button hard-rejects tracks from recommendations - Hybrid search adds youtube.com web videos and playback falls back across providers when a track has no Music streams; wedged InnerTube sessions reset after client failures - Bump SPICE_MEDIA_CORE_VERSION to 1.0.169 with walkthrough notes Android: - Home feed gains the Listeners like you shelf and adopts cloud adaptive priorities; pushes local learning after feedback (debounced) - Search results subtly re-ranked by shared affinity signals with debounced search jobs
…on builds - Replace a stray Windows-1252 byte in smart-queue.ts with a proper UTF-8 em dash; Linux Turbopack failed reading sources otherwise - Register tasteState in db/local-schema-stub.ts so the local runtime build resolves the new table export like the cloud schema does
The /api/listeners route family is cloud-only but was unknown to both prune lists in the local packager, so the route survived pruning while still referencing DB-bearing server chunks and failed the safety check. Register it alongside the other cloud-only prefixes.
