PR author inactivity #208

name: PR author inactivity
# Remind PR authors only when the current blocker is clearly author-owned, then
# close after the blocker has gone stale.
#
# Inactivity heuristic:
# - We look for the PR author's latest response via:
# 1) an issue comment,
# 2) a submitted pull-request review,
# 3) an inline review comment reply, or
# 4) a PR commit / force-push timeline event.
# - We then find the first trusted human reviewer / maintainer feedback that
# arrived after that author response via:
# 1) issue comments,
# 2) non-approval reviews, or
# 3) inline review comments.
# - We also track the latest non-bot human activity on the PR. Reopens,
# comments, reviews, inline review comments, labels, assignments, review
# requests, and pushes all reset the inactivity window.
# - PRs waiting on product direction, QA validation, a non-author assignee,
# requested reviewers, looper, or maintainer-assisted stale handling are not
# author-owned and are skipped by this workflow.
# - Clear author-owned blockers include merge conflicts, failed CI, and
# outstanding trusted reviewer / maintainer feedback.
# - If an author-owned blocker remains and the whole PR has no human activity
# for 72h, we remind once. If it has no human activity for 120h, we close it
# for queue management.
#
# Bot feedback note: trusted human reviewers / maintainers are the trigger for
# this workflow. Bot-authored reviews and comments (e.g. CodeRabbit, Codex) are
# intentionally excluded from the feedback signal so authors are not pressured
# by automated nits alone. Trusted human review feedback — whether top-level or
# inline — is what starts the inactivity clock.
