Changes & Remediations

1. Claude Code Cask Upgrade & Model Verification (jdmbair13m5):

   • Host reboot cleared the mach_msg/bootstrap_look_up3 hang during timezone init in Homebrew's cask fork.
   • Homebrew successfully installed claude-code@latest 2.1.280 at /opt/homebrew/Caskroom/claude-code@latest/2.1.280/claude.
   • Verified default model resolves to claude-opus-5-5[1m] via claude -p ok --output-format json.
   • Verified 4 saved pre-reboot sessions (c59e20b4, 49ff25a1, ff85b4f9, 6249d265) were resumed in Terminal under 2.1.280, plus new active interactive session 31697.
   • Reaped orphaned hung claude --version pre-reboot process (PID 15843).
   • Marked ISSUE-20260922-11 resolved via ticket resolve.

2. Domain Portfolio Inventory Commit (rdmsm4x):

   • Committed updated domains.json and domains.md in rdmsm4x:~/dev/lib/domains (commit 51fa378), recording newly registered/synced domains (e.g. tyrelld.app, hyperfile.net, xattr.app, etc.).
   • Pushed commit to fleet and backup remotes.
   • Cleared dirty checkout in lib/domains, silencing the 30-minute coordinator alarm (uncommitted-work-in-domains) and unblocking RTTy release gate 1.

3. Fleet Message Bus Sync:

   • Published resolution broadcast to all via agent_msg.zsh send (20260923-072400-E0704044).
   • Synced message bus across all 5 peer hosts (agent_msg.zsh sync).

• agent_msg.zsh sync -> all peer hosts (rdmsm4x, rdmbair13m5, rdmbair15m5, rdmpw3265m, rdmpw3275m) reported ok
