Internal algorithm labels — not shown in the main view.

• Sensor Agreement — Fiedler eigenvalue of the sensor graph Laplacian (Sheaf Laplacian coherence)
• Exercise pattern match — Library kNN classifier on FusedFrame v3
• Rep detector — CUSUM changepoint detection (Rust ws-rv3 delta feed)
• Capture gate reason — previously "Fiedler X.XX (needs ≥ 0.40)"; now shown as "sensor agreement X.XX"
• WebSocket protocol — WS-RV3 / WSS frame (session_ended field triggers progress modal)
