autoformat.yml

name: autoformat

# Auto-format .cs files changed in a pull request and commit the fixes back
# to the PR branch. This is the fix-in-place pattern used by dotnet/maui
# (dotnet-autoformat-pr.yml): formatting never blocks a PR, it repairs it.
# BOM enforcement stays separate - see scripts/check-no-bom.sh / the no-bom
# job in pr_validation.yml, because a whitespace-scope format does not strip
# BOMs.
on:
  pull_request:

# Only this workflow needs write access - it pushes formatting commits back
# to the PR branch. pr_validation.yml stays read-only.
permissions:
  contents: write

# A push to the PR branch re-fires pull_request (synchronize). Serialize runs
# per PR so two pushes cannot race on the same branch; if the push already
# landed, the new run finds nothing to do and no-ops.
