ID	Finding	Evidence	Schema/documentation impact	Status
F-01	The intrinsic decoder reproduces the transformed reference output exactly.	Full snapshot comparison; 14 rows; normalized SHA-256 `b0bc62c5314084678cec6352639bdb915f4970a69004ce43f8db8d24533c7493`	The BSD schema is the production source of truth.	Closed
F-02	Row and section boundaries are intrinsic.	Strict decoding reaches exact EOF on the installed capture.	No companion offset table is loaded by this decoder.	Closed
F-03	Reserved byte ranges are representation details.	Their widths are fixed by adjacent fields and full-snapshot parity.	`.pad()` keeps the schema readable and omits redundant output properties.	Closed

ID	Finding	Evidence	Schema/documentation impact	Status
MC-01	Payloads cannot be partitioned from the primary table alone	Variable strings have no outer row terminator	Offset companion is an explicit dependency	Resolved
MC-02	All three string control words are required zero framing	Complete capture and targeted nonzero mutations	Replaced silent skips with `reserved(4)` validation	Resolved

Archived SQLite: all 14 actions exist in ManufactureCondition_Table; build-local hashes and bytes remain the physical authority.
