Fleet diagnosis on rdmsm4x (17:59 to 2026-09-25 18:56:12 EDT): the fleet is healthy. The morning sshd-cap outage is fixed and holding. Filed 5 tickets, fixed lib/domains refresh auto-commit, and committed the regenerated domain data.

• Host: rdmsm4x · Agent: claude@rdmsm4x (session 6d17e121, Opus 5.5 + 2× Sonnet 5 read-only workers)
• Task: fleet-diagnosis-20260925 · Project: fleet
• Window: 2026-09-25 17:59:11 EDT → 2026-09-25 18:56:12 EDT

Scope

Read-only sweep of all 6 hosts (spokes over the tailnet), plus rdmsm4x services: ECSmem0d, devbackup, sharedtreeguard, tyrelld, 1Password, Spotlight, sshd. Also checked rules, config sync, the bus and the ticket store.

Changed

• ~/dev/lib/domains 3d43fe3: committed domains.json/.md that a manual refresh at 16:03 had left dirty. Diff was verified as day counts and generated_at only. This cleared sharedtreeguard's alarm.
• ~/dev/lib/domains 07489e6: refresh_domains.zsh v1.2.0 and refresh_all.zsh now commit their generated files by path (git commit -- <paths>; opt out with DOMAINS_NO_COMMIT=1). Pushed to fleet and backup, both rc=0.
• ~/dev/fleet c6aa77e: diagnosis-20260925/ (REPORT.md, spokes.md, hub-services.md, SESSION-STATE.md).
• Tickets opened: ISSUE-20260925-20 (tyrell ticket_store_health totalIndexed=0), -21 (rdmbair15m5 replicantdb JBIG2 CPU loop), -22 (eastcoastscience.net tracked dev-key.pem blocks backup), -23 (rdmpw3265m IMDPersistenceAgent), TASK-20260925-13 (jdmbair13m5 disk 94%). Resolved: ISSUE-20260925-24.
• Bus: 20260925-185511-2AF09C30 to claude@rdmbair15m5.

Verification

• Domains scripts: zsh -n on both; scratch-repo behaviour test 5/5 (commits the changed set, leaves an unrelated staged file staged, makes no commit when nothing changed, honours the opt-out). git status --short shows 0 lines afterwards.
• Hub sshd copy count 21/42; /usr/bin/log EPROCLIM 2 in 3h. Ticket index 1,270 rows. defaultMode=bypassPermissions.

Undo

• git -C ~/dev/lib/domains revert 07489e6 (the script change); 3d43fe3 is generated data and needs no undo.

Outstanding

• Rich (money): arista.wiki and datasheet.network expire 2026-10-15 with auto-renew OFF; cves.app 2026-11-24, also OFF.
• Notes: this session is Background, so notes_changelog.zsh cannot reach Notes. This file is published by com.rdm.claude-notes-autopublish on its next hourly pass.
