◆ 2 · What happens when you submit

The server canonicalizes the YAML (PRML §3), computes the SHA-256 of those bytes, stores the manifest publicly, and returns a permalink at /<hash> plus a README badge.

◆ 3 · What to do with the hash

• Add the README badge to your repo.
• Cite the permalink in papers and audit reports.
• Use prml-verify-action in CI to gate future merges.
• Anyone with any of the four reference implementations can verify it offline.

◆ 4 · What is locked

Any field change after submission produces a different hash. That's the entire mechanism. Pre-registration is the act of submitting before you run the eval — the hash binds the threshold.
