Red: product_provenance_invalid alone is printed for an artifact sealed under another contract. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
product_provenance_invalid covered a contract mismatch, a producer run mismatch, a revision mismatch and relocation faults, and printed none of them. PR media tours of #14563 refused CI's own product six times on 2026-09-29 with that reason alone. Print the artifact, run and the check that refused it, and for a contract mismatch the fields that differ. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

📝 WalkthroughWalkthroughReceipt validation now reports differing nested contract fields separately from producer run mismatches. Restore logs artifact and run IDs, the exception type, and a truncated error message when provenance validation fails. Tests cover mismatch reporting and sorted field paths.

check whether each key exists on both sides before comparing its value, so a

Which field moved is not recoverable from the logs.This prints the artifact, the run and the check that refused it, and for a contract mismatch the dotted fields that differ (contract values are already public in the receipt).

Review follow-up
Adds explicit refusal reasons when compiled-product reuse cannot adopt an artifact, making cache/adoption failures diagnosable instead of silently falling back to a cold compile.
Validation: 121 focused tests passed. This PR is already merged.
