rdmsm4x-changelog-20260830-1217-post-reboot-agent-resume-and-rdmbair15m5-parity-check

When: 2026-08-30 12:17:47 EDT Host: rdmsm4x (Mac Studio M4 Max) Agent: claude@rdmsm4x (Claude Code 2.1.251, session dev-76) Task from Rich: resume all agents running locally before the reboot; check in with rdmbair15m5 and confirm all remotely-done work is migrated to rdmsm4x:~/dev/.

Summary

Both Claude sessions killed by the 01:53 reboot are resumed and live. The launchd agent stack had been dead for ~10 hours (LaunchAgents cannot start before GUI login) and self-recovered at 12:02 when Rich logged in. Parity with rdmbair15m5 could NOT be verified — that host refuses inbound SSH from every fleet machine. Filed as ISSUE-20260830-25.

Scope

Single host (rdmsm4x) for the resume work. Read-only probing of rdmbair13m5, rdmpw3265m, rdmpw3275m, jdmbair13m5, rdmbair15m5.

What I found

Boot / recovery timeline

• kern.boottime = Sun Aug 30 01:53:16 EDT 2026.
• GUI login (WindowServer, loginwindow) restarted ~12:02 EDT.
• Load average was 130 at 12:07, falling to 56 by 12:11 — normal post-boot storm (DumpPanic, spindump, Spotlight mds_stores/corespotlightd reindex, Time Machine backupd-helper, cloudd). Not an agent fault; it settled on its own.
• Consequence: every com.eastcoastscience.* LaunchAgent was dormant 01:53 -> 12:02. The 12:02:52 independent fleet audit scored rdmsm4x's own heartbeat "STALE 612m" for exactly this reason; the 12:03 heartbeat then delivered normally.

Agents running locally before the reboot

Exactly two Claude Code sessions were live at 01:53 (determined by .jsonl mtimes in the 01:00-01:53 window; no others were touched):

rdmbair15m5 status — the blocker

• Host is UP, not down: rdmbair15m5.local -> 192.168.1.48, answers ICMP (70-93 ms).
• sshd is listening but returns Permission denied (publickey,password,keyboard-interactive) — an auth failure, not a timeout.
• Denied from rdmsm4x directly and when relayed via rdmbair13m5, rdmpw3265m, rdmpw3275m.
• Control test: those same three hosts accept rdmsm4x's key normally. The fault is on rdmbair15m5, not in rdmsm4x's key or agent.
• Tailscale node rdmbair15m5-1 (100.74.59.4) offline; WoL to fc:b2:14:41:58:bd (broadcast + 192.168.1.255 + 192.168.0.255) produced no change.
• Last bus traffic from the host: 11:53:11 EDT. Silent since.

Unverified success claims found while checking parity

1. agy@rdmbair15m5 closeout (bus msg C8E19CFC, 11:53) states the master handoff was written to rdmsm4x:~/dev/_handoff/agy-master-closeout-20260830.md and ~/.agent-coordination/handovers/agy-rdmbair15m5-master-closeout-20260830.md. Neither file exists on rdmsm4x. Reported success, no artifact.
2. ~/dev/_handoff/staged_LogTTY/ and ~/dev/_handoff/staged_replicantDB/ are empty directories created 00:51 — staging targets whose payload never arrived.
3. The named deliverables (lib/ecs0lib, apps/xentropy, apps/updateRoo, apps/AINetNode, apps/LogTTY, apps/replicantDB, apps/Tyrell) DO exist on rdmsm4x, all on main, last commits 2026-08-29. That is consistent with the closeout being a summary of 08-29 evening work. It is not proof of parity — unverifiable while the host refuses SSH.

What I changed

• Resumed claude --resume cd4dc58c-... in ~/dev/apps/replicantDB (PID 85490, Terminal window 357).
• Resumed claude --resume 0da93685-... in ~/dev/apps/logTTY (PID 85556, Terminal window 359).
• Sent bus message 20260830-121523-4B6DCE5D to agy@rdmbair15m5: the SSH blocker, the exact local fix, and a request to PUSH any unique ~/dev content to rdmsm4x:~/dev/_inbox/rdmbair15m5/ with a manifest, since it cannot be pulled.
• Filed ISSUE-20260830-25 (INCIDENT, high) at ~/dev/issues/open/.
• Side effect: 192.168.1.48 added to ~/.ssh/known_hosts by StrictHostKeyChecking=accept-new.

Verification evidence

• pgrep -f "claude --resume" -> 2 processes (85490, 85556), both confirmed running.
• launchctl list | grep eastcoastscience -> all jobs LastExitStatus=0, none failed.
• usage_status -> advice: proceed, worst bucket 13% (anthropic 7d, vendor-authoritative).
• Independent fleet audit 12:02:52 EDT independently scored rdmbair15m5 unreachable, matching my probe.

Outstanding owner actions (Rich)

1. On rdmbair15m5, at the keyboard — restore inbound SSH:

   chmod 755 ~ && mkdir -p ~/.ssh && chmod 700 ~/.ssh
   # append rdmsm4x's key from rdmsm4x:~/.ssh/id_ed25519.pub
   chmod 600 ~/.ssh/authorized_keys
   sudo systemsetup -getremotelogin

2. Until then, rdmsm4x:~/dev/ parity with rdmbair15m5 is UNVERIFIED, not complete.

How to undo

• Close the two Terminal windows (357, 359) to end the resumed sessions; no file state was changed by resuming.
• ticket resolve ISSUE-20260830-25 once SSH is restored and the scan completes.
• Remove the 192.168.1.48 line from ~/.ssh/known_hosts if unwanted.
