✨ Features

• Per-batch lead and polyphonic estimator — each chord batch now computes its own down-lead using an adaptive logic that accounts for the number of simultaneous notes. The SendLatencyEstimator is extended with polyphony buckets and a linear lead model, so chords of different sizes are dispatched with the right anticipation instead of a single fixed offset. (712c02e)
• Exponential forgetting for the latency estimator — introduces a lin_forget factor and RLS-style accumulators, so the estimator tracks recent network/system jitter instead of a stale long-term mean. State serialization and warm-up updated accordingly. (1a94ce2)

🚀 Performance

• Trimmed dispatch hot-path allocations and tightened the spin loop in orchestration/dispatch_loop.py, reducing per-action overhead on the tight perf_counter_ns loop. (7cdb8fb)

🐛 Fixes

• Safe latency deque snapshot — the UI now retries and falls back to an empty list when the latency deque is mutated mid-iteration, instead of raising RuntimeError under load. (4191b83)
• Disable lead cache in DryRunBackend — _lead_cache_enabled now returns False when the active backend is DryRunBackend, preventing a stale cached lead from skewing dry-run timing previews. (911d123)
