No job timeout · CI status
No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.

macOS bills ~10x and Windows ~2x a Linux minute. The cost estimate above assumes Linux, so your real spend is higher. Move any job that doesn't need them to `ubuntu-latest`.

runs-on: ubuntu-latest
timeout-minutes: 15Full-history clone (fetch-depth: 0) · Lints
checkout fetches the entire git history every run (`fetch-depth: 0`) and nothing in the workflow appears to read it. Remove the line; the default shallow clone is much faster on big repos. Keep it if a step genuinely needs history.
