Findings
| ID | Finding | Evidence | Schema/documentation impact | Status |
|---|---|---|---|---|
| F-01 | A typed internal decomposition is not justified. | The leading eight bytes are build-specific pointer-like values, offsets +12 and +16 also change between builds, and no count, delimiter, join, or consumer selects one width hypothesis over alternatives. |
The proposed u64/u32/u32/u16/u16/u32/u32/u32 layout was rejected; the exact 32-byte row remains intentionally raw. |
Closed |
| F-02 | Outer PABR framing is fully proven independently of row semantics. | Both captures contain one row, exact count-derived size, and a valid self-referential footer; all framing corruptions reject. | Physical framing confidence remains Certain. | Closed |
