Seal every agent's PR with proof — earned authority in a signed receipt.
Signetry is a change-control plane for coding agents. Any agent (Claude Code, Codex, Cursor, Copilot, Devin — or a human) may propose a change; only Signetry decides how much authority that change earned, and seals the verdict in an Ed25519-signed receipt.
For every change it runs one deterministic pipeline:
executable contract → untrusted-text quarantine → required checks →
independent verifier → earned authority (0/1/2) → Ed25519-signed receipt
A coding agent cannot approve its own authority to make a change. The patch-writer is never
the patch-approver. auto_merge is always false — a human merges.
