- No unsolicited PR labels/retitles/rebases/fixups/landing. Comments/reviews ok only for reviewable findings, pre-merge proof, or close/duplicate reason after explicit close/sweep/landing request.

- Maintainer decision closes the cluster: if deciding reported behavior/proposed fix is not planned, comment+close all directly associated open issues/PRs unless explicitly told to keep one open. Associated means linked PRs/issues, duplicates, companion workaround PRs, and the canonical issue for the rejected behavior.

- Do not leave associated issues open for hypothetical future repros. Close with rationale; ask for a new issue or reopen only if concrete new evidence appears. Close comment states: decision, why, supported alternative, and what evidence would change the decision.

- Issue/PR numbers need a short summary every time; assume the reader has not opened or read them.

- PR review answer: bug/behavior, URL(s), affected surface, provenance for regressions when traceable, best-fix judgment, evidence from code/tests/CI/current or shipped behavior.

- PR reviewable findings: post them on the PR, not chat-only, so author sees actionable feedback.

- Issue/PR final answer: last line is the full GitHub URL.
