- migration 00006: track features and embeddings (pgvector, HNSW), analysis queue filled by a trigger on new tracks, wave sessions and impressions, recommender profiles, model versions - analyzer basic-1 (ADR-014): ffmpeg decode, three 30 s excerpts, 256-d timbre/rhythm embedding, tempo by onset autocorrelation, key, loudness, energy, danceability, acousticness, intro length; worker with SKIP LOCKED claims, retries and re-analysis on version change - wave engine v1: candidates (session/taste similarity, fresh, liked artists, rediscover, popular, exploration, seed), filters (dislikes, played in 3 h, already served), heuristic score, activity and mood fit from contexts.yaml with relaxing thresholds, MMR with one track per artist, exploration share, session vector updated by reactions and a change of course after three skips - POST /internal/wave/batch with the catalog index cached in memory and the session kept in Redis Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
