undecoded.rs supplies the denominator the coverage numbers never had; the disc holds 6294 XBG7 resources, 6069 decode, 225 are searched and missed, 0 lack a descriptor. gate_histogram.rs attributes each miss to the furthest gate its best candidate reached: 120 connectivity, 74 grouped-pool (different path), 15 degenerate/extent, 9 winding, 7 buffer-not-covered. Recorded as a work-list, not a verdict -- a wrong candidate can pass more gates than the true block. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
