Findings

|---|---|---|---|---|
| F-01 | The intrinsic decoder reproduces the transformed reference output exactly. | Full snapshot comparison; 1,419 rows; normalized SHA-256 ac4aab001d139f7ba69718ee4414de2049fdf9dcec4c002607eaf36ac559f8b1 |
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 |
Reconciled source findings
| ID | Finding | Evidence | Schema/documentation impact | Status |
|---|---|---|---|---|
| F-02 | This is an exact reverse index, not merely a correlated lookup. | Exhaustive pair equality in two builds. | Semantic confidence promoted to certain. | Closed |
