Cron-persistence root-cause dig: standup vs reflection write-path evidence + Victor escalation

Substantive forcing function committed 5/30, re-committed 6/2, re-committed 6/3 with hard 6/4 deadline. 6/4 reflection just filed this BEFORE writing the apology entry — flipping the anti-pattern: action concurrent with reflection, not committed-for-later. CONTEXT: - cron-gateway-scheduler-intermittent has been ACTIVE BLOCK since 2026-05-20. Monthly-ish recurrence: 5/20 stretch, 5/26 reset, 6/1+6/2 reset. Most recent quorum: 1/5 after 6/3 Wed hit broke 2-miss streak. - Standup cron PERSISTENCE is the failure mode (Slack delivery succeeds, disk write to memory/standups/YYYY-MM-DD.md fails). Reflection cron has the SAME selective persistence symptom for memory/YYYY-MM-DD.md files (blocked fleet-task 9a78b59b investigates this). Same gateway, possibly same write-path. - Victor was pinged in May. No new diagnostic data since. The existing alert thread carries the historical record. MECHANICAL STEPS (one foreground session, ~30-60min): 1. cd ~/agents/sergey-engineer. Identify cron job IDs for standup and reflection (check ~/.openclaw/cron/jobs.json). 2. Pull gateway scheduler logs for the 6/1, 6/2 standup MISS runs and the 6/3 standup HIT run. Compare against the reflection cron runs for the same dates. Look at: tool call shapes, write paths invoked, success/failure return codes, any silent error swallowing. 3. Cross-reference with blocked task 9a78b59b investigation notes (session jsonl /home/agent/.openclaw/agents/sergey-engineer/sessions/7ceebd48-97a1-4540-b4f2-77e4981a6516.jsonl). 4. Write a 1-2 page diagnostic doc at projects/cron-persistence-rootcause-2026-06.md with: failure pattern timeline, write-path comparison, working theory, repro hypothesis, what evidence would confirm. 5. ONE threaded reply on the existing alert thread to Victor (NOT a new top-level DM) with the doc summary + link. No fresh escalation channel. 6. Update this fleet-task: status=completed with PR-style result (doc path + DM message_ts). NOT a heartbeat-poll pickup. Foreground/run session per 5/27 + 5/30 rules. Bound artifact: projects/cron-persistence-rootcause-2026-06.md exists + Victor thread reply with diagnostic link.
