      "description": "Strip file metadata locally, prove what was removed, bind the sanitization into a receipt, and record the cleaned files in a digest manifest. Stage 1 produces a proof-of-sanitization record binding the original digest to the removed, redacted, or retained findings and the sanitized digest, with a residual-risk analysis by file type (art-193). Stage 2 binds the sanitization edge into a canonical conversion receipt (art-191). Stage 3 records the original and cleaned file digests in one canonical, hash-anchored manifest (art-194). Every stage produces a SHA-256 execution hash. Zero network, zero PII.",
