A text error list does not show how failures are distributed across historical source versions or let developers aggregate repeated rejection reasons. Emit and save the same JSON report with per-version outcomes, stable failure groups and per-input diagnostics, plus runtime, checkout and report locations. Keep source versions from physical discovery rather than migrated handle headers. Classify only known diagnostic fields such as unexpected members, unknown events, child prerequisites and sequence gaps. Preserve original messages and use an explicit fallback for other failures; the report makes no inference about historical producer bugs and cannot influence admission or retry decisions. Regression checks cover printed/file/log equality, private report files, grouped distinct sequence coordinates and source-file preservation.
