# Stamp key coexistence proof

This folder binds Joe Boll’s **CMS**, **GPG**, and **PQ** signing keys together.

| File | Role |
|------|------|
| `COEXISTENCE-ATTESTATION.txt` | Binding statement (lists all key fingerprints) |
| `cms-joe.crt` | CMS / PAdES public certificate |
| `gpg-A27F71AB1E015272.asc` | OpenPGP public key |
| `pq-mldsa65.pub` / `pq-slhdsa.pub` | Post-quantum public keys |
| `signatures/` | Detached signatures from **each** key over the attestation |
| `VERIFY.md` | How to check the cross-attestation |

**Meaning:** each private key signed the same statement that names all the others. That is the coexistence / cross-attestation proof.
