# Workflow: Stale Requested-Changes PRs
# ======================================================================================
# Usage:
#   - Runs daily and follows up on external-contributor PRs that have an active
#     requested-changes review and have gone inactive.
#   - Posts reminder comments at 7 and 10 days of author inactivity, then closes
#     the PR at 14 days — but only after the day-10 final warning has been posted.
#   - Inactivity is author-driven: a head-branch push (GitHub-recorded) or a comment by
#     the PR author resets the timer; maintainer/third-party/bot comments do not.
#   - Reminder progress is tracked via marker comments authored by github-actions[bot],
#     so no datastore is needed.
#
# Modes (workflow_dispatch `mode` input; scheduled runs use `full`):
#   - dry-run:        log eligible PRs and intended actions, write nothing.
#   - reminder-only:  post reminders, never close.
#   - full:           post reminders and close.
