Original deliveries under two explicit policy choices

Retrospective summary of retained first-delivery replays. No producer repair used in these comparisons.

Unrepaired delivery	Original requirements, migrated	Revised owner policy
Conveyor	INSUFFICIENT_EVIDENCE: 16 PASS, 6 UNKNOWN; the open sign face is outside the closed-solid policy.	ACCEPT_FOR_USE: 24/24
Process skid	REJECT: port direction vocabulary and boundary contact; nameplate unresolved.	ACCEPT_FOR_USE: 13/13
Storage aisle	REJECT: flush contact; open wrap geometry unresolved.	ACCEPT_FOR_USE: 14/14

What changed

Select whole subtrees with declared exclusions instead of hand-listed obstacles.
Treat open meshes as surfaces.
Allow boundary contact within a 1 mm physical allowance.
Declare bidir as an alias for bidirectional.
Add supported partial bounds, attribute-value, rotation-rate and relative-motion requirements.

What the comparison establishes

Supported ordinary geometry can be assessed without asking the producer to triangulate or close it first, when the owner chooses an appropriate surface and contact policy. The policy change is part of that result.

The owner selected the revised policies after seeing earlier results, including the exclusions and allowance. This is not a code-only comparison.
Builders, reviewers and evaluator used Claude on synthetic briefs; this is not an independent benchmark.
No claim of defect frequency, general model accuracy or reduced reviewer effort.
The initial no-brief scene and seeded fault matrix are not counted in the three-delivery comparison.
This is a selected result excerpt, not a complete scene replay. Original delivery bundles and run logs are not included.
