Updated this M5 Air's LLM tooling and model inventory after fleet maintenance while preserving host-local identities and privacy-safe benchmark boundaries.

Scope and changes

• Reconciled ~/.claude/CLAUDE.md, ~/.codex/AGENTS.md, ~/.gemini/GEMINI.md, and ~/.agent-coordination/FLEET.md with the six-host canonical path block pointing to rdmsm4x:/Users/richh/dev.
• Completed /Users/richh/dev_update.zsh; no outdated formulae or greedy casks remained. brew doctor reports only the expected macOS 27 Tier-2 support notice.
• Repaired the Antigravity cask receipt collision; backup: /Users/richh/.agent-coordination/backups/antigravity-cli-receipt-20260823T022649.
• Verified Claude Code 2.1.241, Codex CLI 0.149.0, agy 1.1.19, Antigravity 2.9.1, Antigravity IDE 2.5.5, and Ollama 0.32.15.
• Installed qwen3.8:27b-mlx and qwen3.5:35b-mlx. The 27B benchmark was stopped after an abnormally long warmup under concurrent maintenance, so no result was published from this host; validated Air results were collected from two M5 13-inch peers instead.

Verification and privacy

• Fleet topology audit passed 6/6; managed config and statusline hashes match the fleet baseline.
• Bounded TCC audit found no explicit denied or limited LLM/terminal records in the audited system scopes.
• No provider authentication, cookies, history databases, signing keys, prompts, generated responses, hostnames, paths, serials, IPs, or personal identifiers were copied or published.

Undo and owner actions

• Restore the Antigravity receipt from the dated backup only if required.
• Remove an Ollama model only with ollama rm <model> after owner review.
• Complete Ollama sign-in interactively in this host's correct account lane if desired; no account was selected by automation.
