Module conformal_frame_guard 

Conformal frame guard: coverage-guaranteed prediction intervals for frame timing.

Wraps ConformalPredictor with a frame-time time series, nonconformity score tracking, and p99 prediction intervals. When the predicted p99 exceeds the frame budget, degradation is triggered.

Fallback: before calibration reaches min_samples, a fixed 16 ms budget threshold is used (no conformal interval).

Integration

The guard sits between frame measurement and [BudgetController]:

frame_time ──► ConformalFrameGuard ──► P99Prediction

                  observe()              exceeds_budget?
                  (calibrate)           → trigger degrade
