The auto-injected GITHUB_TOKEN defaulted to write-all in ci.yml, bench.yml and release.yml (no top-level permissions block), and codeql.yml declared its scopes only at job level. Add a top-level `permissions: contents: read` to all four so the token starts read-only and only the jobs that genuinely write through it raise the scope: - release.yml: github-release keeps contents: write; node-/wasm-publish and attestations keep their id-token / attestations: write blocks. The cargo/python/node publish jobs push to crates.io/PyPI/npm via their own registry secrets, not the GITHUB_TOKEN, so read-only is correct for them. - codeql.yml: analyze keeps security-events: write (job level). - ci.yml / bench.yml: no job writes back to the repo (coverage uploads via CODECOV_TOKEN; bench only uploads an artifact), so no job override is needed. sync-about.yml already had a top-level block but at contents: write; demote the top level to read and move contents: write down to the single `sync` job (the PR-head counter push is the only GITHUB_TOKEN write). The cross-repo About/docs/webpage/org writes are unaffected — they run through the fine-grained ABOUT_SYNC_TOKEN, which the permissions key does not govern. Raises OpenSSF Scorecard Token-Permissions from 0 toward 10.
