# Supplied Artifact Manifest Check

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Compare a supplied text-file manifest with supplied UTF-8 contents: byte sizes, SHA-256 digests, missing/extra/duplicate paths and bounded portable-path collisions. Does not read a filesystem, decode archives, trust an unsigned manifest or verify publisher identity.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Verify an agent artifact handoff against expected file hashes and sizes
- Detect missing files, duplicate paths and portable filename collisions

## Outside this profile
- Signature verification, malware detection or archive extraction
- Reading remote or local files, binary contents, or complete cross-platform filename validation

Proposed nominal USD 0.01 per successful call; payer fees excluded. No verified runtime availability.
