The cold ACP probe captured available_commands but read probedCommands synchronously right after newSession, racing opencode's async available_commands_update notification -> captured nothing, only the static manifest showed. The probe now waits (poll <=3s + 300ms settle) for the notification. Captured commands persist to a new available_agents.commands column and are served (merged with the manifest) on the tier-2-skip path, so the agent's discovered commands survive once models are warm and show without a dispatch. Boot warms via the force:true startup snapshot. Caveat: relies on opencode emitting available_commands_update on session creation, not only post-prompt.
