Findings

ID Finding Evidence Schema/documentation impact Status
IMLO-01 The final row word is a reserved byte range rather than a returned numeric field. It has no required semantic role in resolving any of the 29,204 pointers. The BSD schema consumes it with bytes(4).reserved() and makes no value claim. Closed
IMLO-02 The migrated BSD output is exactly reference-equivalent after retaining the informational footer pointer. Full directory-order comparison matched 29,204 rows and footer offset 350,456 with digest 331c51cc343888f7fcb6cd34c803b8bab304000affe0b64f067d4eef26d567cf. Footer pointer is added to the transformed oracle rather than removed from BSD output. Closed
IMLO-03 Every pointer resolves one fixed-width payload row. Zero key or offset mismatches against all 29,204 itemmaxlevel.dbss rows. The directory remains useful evidence but is not a payload-decoder dependency. Closed
