rdmsm4x-changelog-20260822-2234-capacity-handoff-and-buzz-audit

Completed a preservation-first, read-only six-host audit of agent/runtime readiness, quota telemetry, preemptive handoff design, Joey's Antigravity lane, rule consistency, and Block Buzz feasibility; this establishes a verified design gate without changing provider authentication, shared agent configuration, project source, or fleet services.

Scope

• Execution host: rdmsm4x.
• Read-only fleet targets: rdmsm4x, rdmbair13m5, rdmbair15m5, rdmpw3265m, rdmpw3275m, and jdmbair13m5.
• Provider surfaces: Claude Code/Claude desktop presence, Codex CLI/Codex desktop presence, Antigravity/agy, and the existing cross-agent mailbox.
• Design surfaces: rLLM capacity display/publisher, rdmsm4x capacity guard, project checkpoint/handoff lifecycle, post-reset resume gate, and an optional future Buzz room mirror.

Files added or updated

• Added /Users/richh/dev/fleet/maintenance/reports/runtime-auth-matrix-20260822.md.
• Added /Users/richh/dev/fleet/maintenance/reports/capacity-handoff-interface-audit-20260822.md.
• Added and updated /Users/richh/.agent-coordination/checkins/codex-rdmsm4x-capacity-handoff-rules-audit-20260822.json.
• Added this changelog at /Users/richh/dev/LLM/Claude/changelogs/rdmsm4x-changelog-20260822-2234-capacity-handoff-and-buzz-audit.md.
• Created immutable coordination messages for Claude, Codex, and Antigravity reviewers and acknowledged the completed Codex alignment/status-meter handoffs. Mail and check-in replicas were synchronized through the existing six-host hub workflow.
• Used a shallow temporary clone of the official Block Buzz repository under /tmp for read-only feasibility inspection. No Buzz source or service was installed in the canonical development estate.

Commands and checks run

• Resolved the local host with scutil --get ComputerName and confirmed rdmsm4x.
• Ran agent_msg.zsh whoami, sync, inbox --unread, read, send, reply, and ack against the existing coordination mailbox.
• Ran fleet_checkin_sync.zsh and verified six-host check-in replication through rdmsm4x.
• Used bounded SSH login-shell probes to verify each target's ComputerName, OS/architecture, provider executable/version, supported Claude/Codex authentication status, active process counts, app presence, and mailbox reachability.
• Used a metadata-only sudo -n -u joey probe on rdmbair13m5 to confirm the Joey account/home, global agy executable access, global Antigravity app visibility, absent account-local config directories, and lack of an active Joey Aqua session. No account file content was read.
• Inspected existing rLLM capacity models and project scope, existing handoff schema/lifecycle concepts, fleet policy/role documentation, and independent Claude review evidence.
• Verified the local Docker/Compose capability and the existing port-3000 listener before evaluating Buzz's production Compose requirements.
• Inspected official provider and Buzz documentation and the current Buzz release/issues; no provider or Buzz authentication was attempted.
• Validated the coordination check-in with jq -e . after its status update.

Verification evidence

• All six expected SSH targets returned the matching ComputerName and a working mailbox command.
• Codex CLI and Claude Code are executable on all six hosts. Supported status checks show Codex logged in on five and Claude logged in on three; jdmbair13m5 is not logged in to either. Antigravity/agy is installed on five and absent on jdmbair13m5; its authentication remains unknown because the observed CLI has no supported non-interactive auth-status command.
• Joey on rdmbair13m5 can execute the global agy 1.1.19 binary and read the global Antigravity app bundle, but has no account-local Antigravity/Gemini configuration and no current desktop session for interactive OAuth.
• Claude Code independently returned PASS WITH OWNER ACTIONS for the six-host Codex/Claude alignment. Mailbox delivery is explicitly not treated as provider authentication, task acceptance, or completion.
• The capacity audit defines provider-specific truth boundaries, a sanitized versioned snapshot, warning/checkpoint defaults, a prepared-to-completed handoff lifecycle, and a fresh-post-reset resume gate.
• Buzz is useful as a future project-room/view layer, but it did not pass the tonight-as-control-plane gate: its deployment adds a relay plus database/cache/object storage, its default port conflicts with the existing Grafana listener, its ACP adapters do not provide a native Antigravity lane, and current agent permission/reply issues require a canary before production use.

Security observation

• During an early broad read-only inspection, an insufficient redaction pattern caused a historical Cloudflare Global API Key value to appear in a private tool-result transcript. The value was not written into either audit report, this changelog, a workspace file, or a coordination message. A later metadata-only scan did not find the matching text in the initially attributed current file, so the exact historical source remains unresolved.
• Owner action: change/revoke the exposed legacy Global API Key, review Cloudflare audit activity, and replace any required automation with a least-privilege API Token scoped to the necessary zone/DNS operations. Store only the replacement credential's name/location in documentation; never its value.

Backups and rollback

• No existing provider configuration, authentication store, installed app, shared policy, or project source was changed, so no configuration backup was required.
• The two reports and this changelog are additive evidence. If superseded, retain them and point to the replacement rather than rewriting history.
• Coordination messages are immutable and should be superseded by a later lifecycle message rather than deleted.
• The audit check-in can be closed by setting its lifecycle to completed and ownership_released to true after design resolution and final reporting.
• The temporary Buzz clone is disposable and is not a canonical project copy.

Outstanding owner actions

1. Rotate the exposed Cloudflare Global API Key and review account audit activity.
2. Approve or revise the recommended rLLM plus rdmsm4x capacity-guard architecture and hybrid automatic-checkpoint/acknowledged-handoff policy.
3. Wait for the existing codex@rdmbair15m5 shared-path lease to be explicitly released before any overlapping policy/config edit.
4. Complete Joey's Antigravity Google-account OAuth in an authorized Joey session on rdmbair13m5; do not copy another account's token, Keychain item, config store, or native history.
5. Keep Buzz deferred to a pinned, Tailscale-only, one-project canary after the durable capacity/handoff control plane passes tests.
