Add top-level permissions blocks to restrict GITHUB_TOKEN scope, resolving 24 CodeQL code-scanning alerts (actions/missing-workflow-permissions). Without explicit permissions, workflows get the repo's default token permissions, which is typically overly broad. This follows the principle of least privilege — if a compromised action runs, it only has the minimum access needed. - action-ci.yml: contents: read - pr.yml: contents: read - pre-commit.yml: contents: read - release.yml: contents: read (jobs needing write already have explicit blocks) - security_audit.yml: contents: read, security-events: write - typescript_library.yml: contents: read

Summary
Resolves all 24 open CodeQL code-scanning alerts for
actions/missing-workflow-permissions.Problem
Without an explicit
permissionsblock, theGITHUB_TOKENin each workflow gets the repository's default permissions, which is typically read/write on all scopes. This violates the principle of least privilege — if a compromised or malicious action runs in any of these workflows, it has more access than necessary.Fix
Added a top-level
permissions: { contents: read }block to each workflow file, restricting the token to the minimum required scope:action-ci.ymlcontents: readpr.ymlcontents: readpre-commit.ymlcontents: readrelease.ymlcontents: readsecurity_audit.ymlcontents: readtypescript_library.ymlcontents: readAll workflows only need read access to check out code and run builds/tests. Jobs in
release.ymlthat require elevated permissions (version-bump,github-release,publish-docker) already have explicit job-levelpermissionsblocks that override the workflow-level default.Alerts Resolved
24 medium-severity CodeQL alerts across 6 workflow files.
