Per-frame [MOV] telemetry + wall_hold mechanical assertion (G-A2600-001 AC#2 mechanized)

Human verdict 4 confirmed walls hold visually; this finding converts that observation into a deterministic, regression-guarded Layer-3/4 assertion. (a) [MOV] moved from the 60-frame DBG cadence into the per-frame [PAC] telemetry block — at the old cadence a 30-frame wall-hold window contained at most one sample, indistinguishable from dead telemetry.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
