Execute ephemeral autonomous work units

Execute a single work item autonomously and self-terminate

Single-task ephemeral agents that execute one bead to completion and terminate, never re-activate.

• · work item (bead) on agent hook
• · isolated git worktree context
• · GUPP protocol activation

• · feature branch with commits
• · completion mail to mayor
• · durable state file (hook cleared)

• · git (branching, commits, push)
• · StateManager for hook/status writes
• · AgentMessage mail protocol

• · Work item assigned to hook
• · Agent running in isolated workspace
• · StateManager initialized with .chipset/state/ dir
• · GUPP protocol understood by caller

• · Unexpected crash: context lost if hook state not persisted
• · Branch creation fails: disk space or git corruption
• · Push fails: remote unreachable or permission denied
• · Work incomplete: acceptance criteria not met before done step

• · Explicit four-step lifecycle (check-announce-execute-done)
• · Durable hook state survives process crashes
• · Context recovery logic on restart documented
• · No re-activation: clear lifecycle boundary prevents deadlock
