Standalone verifier

Compute the hash in your browser.

No upload, no commit, no server round-trip. Paste a PRML manifest. See the canonical bytes and the SHA-256 it would commit to. Optionally compare against a known hash.

This page runs the registry's own canonicalization module (canonical.js, validated against all 21 frozen conformance vectors in CI). For verification that does not trust this registry at all, use any of the four reference implementations offline.
