#### optimize GET /tracks/top latency (PR #879, Feb 8)
51
+
52
+
**baseline (production, 171 requests over 3 days)**: p50=123ms, p95=1204ms, p99=1576ms. the p95/p99 spikes were caused by stale connection reconnects during `pool_pre_ping` and redundant DB round-trips.
53
+
54
+
**optimizations**:
55
+
- **merged query**: new `get_top_tracks_with_counts()` returns (track_id, like_count) tuples in a single GROUP BY — the count was already computed to sort, now it's returned instead of discarded. eliminates a redundant `get_like_counts` call (1 fewer DB round-trip)
56
+
- **scoped liked query**: the authenticated user's liked-track check now filters by `track_id IN (...)` (10 rows) instead of scanning all user likes
57
+
- **pool_recycle 7200s → 1800s**: connections recycle every 30min instead of 2h, reducing stale connections that trigger expensive reconnects
58
+
59
+
**verified via Logfire traces**: authenticated requests dropped from 11 DB queries to 7. post-deploy requests at 517-600ms vs baseline p95 of 1.2s.
60
+
61
+
**14 new regression tests** covering ordering, limit clamping, auth state, like counts, comment counts, and tags.

#### auto-tag at upload + ML audit script (PRs #871-872, Feb 7)

**auto-tag on upload (PR #871)**: checkbox on the upload form ("auto-tag with recommended genres") that automatically applies genre tags after classification completes. user doesn't need to come back to the portal to apply suggested tags.
