Pins the default GITHUB_TOKEN to contents: read on the 11 workflows in .github/workflows/ that don't actually need any write scope: - alt_linux_distros.yml, docker.yml, test_*.yml, trickops.yml: build/ test workflows, no GitHub API. - report_*.yml: status-report workflows. - code_coverage.yml: uploads coverage to Coveralls via coverallsapp/github-action; the GITHUB_TOKEN there is used for identification with coveralls.io, not for any GitHub API mutation, so contents: read is sufficient. Motivation: CVE-2025-30066 (March 2025 tj-actions/changed-files compromise) exfiltrated GITHUB_TOKEN from workflow logs. Per-workflow caps bound runtime authority irrespective of repo or org default, give drift protection if the default ever widens, and are credited per-file by the OpenSSF Scorecard Token-Permissions check. YAML validated locally with yaml.safe_load. Signed-off-by: Arpit Jain <arpitjain099@gmail.com>

CVE-2025-30066 (March 2025
tj-actions/changed-filessupply-chain compromise) exfiltratedGITHUB_TOKENfrom workflow logs and the leaked token retained whatever scope was issued at the workflow level. Pinning per workflow caps that runtime authority irrespective of the repo or org default, gives drift protection if the default ever widens, and is credited per-file by the OpenSSF ScorecardToken-Permissionscheck.YAML validated locally with
