|---|---|---|---|---|
| F-01 | The intrinsic decoder reproduces the transformed reference output exactly. | Full snapshot comparison; 124 rows; normalized SHA-256 112d48e0450206850c9d5a9070b1e25b7b1c610e1fa0f009916cdc7096d5c4c4 |
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. |

Reconciled source findings
| ID | Finding | Evidence | Schema/documentation impact | Status |
|---|---|---|---|---|
| F-01 | Companion corroborates but is not required by production. | Primary counts frame every selector list. | Decoder remains independent. | Closed |
