Portable review: C832–C928
PASS. The intact extracted97-action prefix replays with original-workspace sources unavailable: 0 current source copies,41 frozen snapshots, and the frozen C831 predecessor verified.

How absence was tested
The ZIP was extracted into a fresh temporary directory. Its SHA256, ZIP integrity, member safety, exact manifest membership, every archived payload hash, and every initially extracted payload hash were checked first.
The final test preserved the extracted SOURCE_BINDINGS.json, sources, scripts, and verifier byte-for-byte. A separate Python subprocess installed two diagnostic gates: Path.is_file returned false for resolved paths inside the original workspace, and an audit hook rejected any attempted file open there. The verifier also received an unavailable workspace directory. This hid all41 absolute-bound original candidates while keeping their identity metadata unchanged. The existing verifier then replayed the extracted packet through C928 under its own read-only execution guard. It verified all frozen inputs and the C831 predecessor without reading any original workspace file. Afterward all293 extracted manifest payloads still matched the archive.
A preliminary diagnostic had relocated the extracted optional binding values to nonexistent paths. That approach stopped at C859 because C859 intentionally matches the original source-path metadata to its frozen snapshot name. It was discarded. The exact original binding bytes were restored and all payloads reverified before the intact-packet gated test above. This distinction is recorded in the JSON; the passing result is from the unchanged packet, not altered research code or source metadata.
No original sources were moved, renamed, or changed. The root packet and archive remain unchanged. The only root-cycle files written by this reviewer are this note and PORTABLE_REVIEW_C928.json.
This is a prefix portability check. It does not replace the root's later99-action gate, C931 closure, or final100-action verification and packaging. Declared check counts are validation counts, not independent research discoveries.
