rdmbair15m5-changelog-20260821-0440-fleet-normalization-standdown-and-status-handoff

Summary: rdmbair15m5 reported its state to rdmsm4x, discovered rdmsm4x had already claimed sole-orchestrator role for fleet normalization, verified three of its claims independently, and stood down. Ownership of the fleet-normalization queue is now unambiguous — one writer, not two.

Scope

Hosts touched: rdmbair15m5 (writer), rdmsm4x (receives synced check-in). No other host.
Mutations: coordination records only. No config, package, script, or system change.

What changed

Path	Change
`rdmbair15m5:~/.agent-coordination/checkins/claude-rdmbair15m5-status-report-to-rdmsm4x.json`	created, then revised to acknowledge stand-down
`rdmsm4x:~/.agent-coordination/checkins/claude-rdmbair15m5-status-report-to-rdmsm4x.json`	received via union sync
`rdmbair15m5:~/.agent-coordination/checkins/`	pulled 1 new peer record (`claude-fleet-normalization-20260821-orchestrator.json`); 13 → 15 records

Commands run

scutil --get ComputerName
ssh -n [email protected] '...'            # read-only probes: ISSUES.md, SESSION-STATE.md, ~/.claude.json
zsh fleet_checkin_sync.zsh                  # peer mode, union-only, run twice
security find-identity -v -p codesigning
tailscale status --self=true

Verification evidence

Check-in JSON validated with python3 -c "import json; json.load(...)" before each sync.
Sync reported rdmbair15m5 -> rdmsm4x and rdmsm4x -> rdmbair15m5, local check-ins now: 15.
Orchestrator claims independently confirmed on this host at 08:35Z: 24 skills; 22 enabledPlugins entries / 6 enabled; Tailscale up at 100.75.253.27 (matches its table exactly); hooks/run-hook.cmd mode 755.
rdmsm4x auth confirmed: oauthAccount present, numStartups=14, live PIDs 10542/13573/18645. This retires the 04:19 checkpoint's central blocker.
ps -p 91746 returns nothing — the PID the orchestrator addressed is dead; live session is 67796.

Undo

Delete ~/.agent-coordination/checkins/claude-rdmbair15m5-status-report-to-rdmsm4x.json on rdmbair15m5 and rdmsm4x. Nothing else to reverse. The sync script is union-only and never deletes, so no peer record was overwritten or lost.

Outstanding owner actions

Rotate the UDM root password found in cleartext in a transcript on rdmpw3275m. Transcripts are not retroactively sanitized.
Sign in through Xcode on rdmbair15m5 — re-verified today: 0 valid code-signing identities, no .p12, no App Store Connect .p8. Device runs, notarization and App Store submission blocked.
Apple Notes filing (P8) still pending on this host. This session's launchctl managername is Background, so AppleEvents to Notes are dead. Needs a run from Terminal.app in the desktop session, or filing from rdmsm4x on this host's behalf. Not silently skipped — recorded here.
