+# Changelog
+
+## 0.2.0 — 2026-10-09
+
+### Added
+- **Stellar anchor signer** (`src/anchor.ts`). The worker can now build, sign,
+  and submit the `anchor` call on the evidence anchor registry itself, using
+  `STELLAR_SIGNER_SECRET` and `STELLAR_EVIDENCE_ANCHOR_CONTRACT`. Previously
+  anchoring required an external signing service that did not exist, so the
+  `stellar-anchor` job could never complete. The external service is still
+  supported and takes priority when configured. Retries are safe because the
+  contract treats an identical anchor as a no-op.
+- 49 new tests (10 to 59): manifests, both anchor clients, environment
+  selection, wallet-signature verification, role permissions, hashing, and
+  claim validation.
+- Prettier, with `format`, `format:check`, and a CI step.
+
+### Fixed
+- `permitted()` threw a `TypeError` for role names such as `__proto__` or
+  `constructor`, which resolved through `Object.prototype`. It now denies them.
+- The security contact address in the README and SECURITY.md had a typo
+  (`gmaill.com`), so vulnerability reports could not be delivered.
+
+### Changed
+- Reformatted all source. The worker and API were written as single very long
+  lines (up to 800 characters), which made review impractical. No behavior
+  change: the same tests passed before and after.
+- The duplicated evidence and attestation anchor code in the worker now shares
+  one implementation.

+## Stellar anchoring
+
+After evidence is processed, the worker records a SHA-256 of a manifest (digests and opaque references only, never evidence content) on the `evidence_anchor_registry` contract from [`afterprint-contracts`](https://github.com/Afterprint/afterprint-contracts). Choose a signing method in `.env`:
+
+| Method | Set | Notes |
+|---|---|---|
+| In-process | `STELLAR_SIGNER_SECRET`, `STELLAR_EVIDENCE_ANCHOR_CONTRACT` | The worker builds, signs, and submits the Soroban transaction. The key must be the registry's controller. Testnet only. |
+| Signing service | `STELLAR_ANCHOR_SERVICE_URL`, `STELLAR_SIGNER_TOKEN` | Takes priority when set. |
+
+With neither set, anchor jobs stay pending and retry, so nothing is lost. Retrying is safe: the contract treats an identical anchor as a no-op and rejects a conflicting one. See [`src/anchor.ts`](./src/anchor.ts).
