Findings
| ID | Finding | Evidence | Schema/documentation impact | Status |
|---|---|---|---|---|
| ITGFO-01 | No pointer-row grammar can be inferred from this capture. | Zero pointers and zero bytes after the required count | No speculative future row schema is encoded | Closed |
| ITGFO-02 | The BSD output exactly matches the complete reference output. | Normalized SHA-256 11bb2244d3693b19ebad11e18bc0fa9fe58b818cd6e21c9e5b19eccc9dbefda2 |
The companion remains independently decoded and unjoined | Closed |
