Promote the enriched-tag weight (#1490) from a taste.Config default into the DB-backed tuning lab so operators can dial how much folksonomy tags count vs raw ID3 genre (rule #25). - Migration 0044: taste_tuning.enriched_tag_scale (DEFAULT 0.5, backfills the existing row). - recsettings: TasteTuning gains the field; seeded/read/updated through reconcile + persistTaste; applyTastePatch validates it to [0,1] (generic non-half-life clamp) and diffTaste audits it; TasteConfig maps it into the profile build. - API: tasteTuningResp exposes enriched_tag_scale. - Web tuning card: a data-driven "Enriched tag weight" knob (0 = genre only). Tests: recsettings persist+range, web fixture field. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
