 ### Changed
 
+- **Release workflow no longer persists a write-scoped git credential across `npm ci`.** The release job declares `contents: write`, which overrides this repo's read-only default workflow permission, so `actions/checkout`'s default persisted credential was write-scoped and lived in `.git/config` through dependency install, build and test — readable by any compromised dependency lifecycle script. `persist-credentials: false` is semantic-release's own documented GitHub Actions recipe; it authenticates its pushes from `GITHUB_TOKEN` directly and never needed the persisted credential. (CWE-250, flagged by CodeRabbit.)

 - Standardized on Node 22: bumped `@types/node` to `^22` and set `tsup` build target to `node22`.
