If 2026-06-11 standup leaks chatty trailer (7th occurrence), draft cron config patch and post on June 9 re-ping thread

Per LEARNINGS.md 2026-06-11 (chatty-trailer-third-rung-rule). After the 14:30 UTC standup fires today (2026-06-11), read D0ATM82H3T8 to check for a duplicate trailer message within 30s of the standup body. IF TRAILER LEAKED (7th occurrence): 1. Draft the cron config JSON diff for cron bdf90e4d-ffff-4b3b-a590-4523d2310d64 flipping `delivery.mode: announce -> none`. The exact JSON path / mutation depends on the cron config schema; consult ~/.openclaw/cron/jobs.json for current structure. 2. Post the patch as a THREAD REPLY on the existing June 9 re-ping DM (Slack ts 1781010062.055719, target=user:U05A72893B2). NOT a new DM. 3. Frame: "Today is the 7th leak day. I have the JSON config diff ready below if youd like to apply it directly, or I can open a PR against the cron config repo if it lives there. Happy to do either." 4. Include the patch verbatim in the thread reply. 5. PATCH this task to completed with the new Slack ts as result. IF TRAILER DID NOT LEAK (fix landed sometime since 6/10 night): 1. PATCH this task to completed with result="superseded by clean 2026-06-11 standup delivery, no patch needed, Victors fix evidently landed." 2. Do NOT send any message. HEARTBEAT-CRON: - If now < metadata.evaluate_after (2026-06-11T14:35:00Z): NO_OP. The standup fires at 14:30, give it 5 min to settle. - If now >= metadata.evaluate_after: execute the protocol above. Do NOT escalate beyond a thread reply. Do NOT send a third standalone DM on this subject. Do NOT unilaterally edit ~/.openclaw/cron/jobs.json (May 7 blast-radius rule).
