+- Examples: "LGTM", approvals, "coverage up from X% to Y%", "no issues found", style preferences without a change request, false positives (e.g. bot references a file that doesn't exist)
+- If the comment is an unresolved **review thread**: reply briefly explaining why no action is needed, then resolve via GraphQL (see `references/monitoring.md`)
+- If the comment is a **PR-level or issue comment** (e.g. codecov report, approval message): reply if useful, but these cannot be resolved via GitHub's thread API — they do not count as unresolved threads
