+## What's New in 3.1.0
+
+Jarri Spooty 3.1.0 introduces the first generation of operational truth contracts.
+
+New capabilities include:
+
+- Operations Snapshot API
+- Candidate selection provenance
+- Selected YouTube candidate persistence
+- Rejected YouTube candidate persistence
+- Candidate scoring visibility
+- Candidate selection reasoning
+- Improved Workspace diagnostics
+- Backend-owned operational truth for future Workspace integrations
+
+Spooty now exposes why a candidate was selected rather than treating YouTube matching as a black box.

+This endpoint provides:

+- Queue depths
+- Active searches
+- Active downloads
+- Playlist counts
+- Track counts
+- Failure summaries
+- Candidate-selection metadata

+The endpoint is intended for Workspace integrations and diagnostics surfaces.
