| Field/path | Offset and width | Representation | Claimed meaning | Physical confidence | Representation confidence | Semantic confidence | Evidence | Status |
|---|---|---|---|---|---|---|---|---|
| PABR controls | header/count/footer | magic retained; count consumed; footer consumed with .pad(12) |
pointer framing | Certain | Certain | Certain (structural) | Exact PABR decode and strict EOF | Closed |

offset, byteLength |
row +4, two u32 |
retained | exact companion span | Certain | Certain | Certain | Every intrinsic row boundary matches | Closed |
| Reserved ranges | schema-local fixed widths | consumed with .pad() and omitted |
framing or semantically neutral capacity | Certain | Certain | Neutral | Adjacent fields, strict EOF, and exact snapshot parity establish each width | Closed neutral |

Findings

|---|---|---|---|---|
| F-01 | The intrinsic decoder reproduces the transformed reference output exactly. | Full snapshot comparison; 12,086 rows; normalized SHA-256 34da5a3f576f8944d3ce5d29d7c49b95b38a22d5e26865459751aa60374b6655 |
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
