 **Why it works:** Naturally models the wizard hierarchy. Queries like "who can do X?" and "what blocks task Y?" resolve instantly.

 **Where:** Every wizard deployment
-**How:** OpenClaw gateway handles external communication. Hermes body handles reasoning. Both on same machine via localhost. Four states: Robed, Unrobed, Lobster, Dead.
-**Why it works:** Separation of concerns. Gateway can restart without losing agent state.
-**Every agent must:** Know their own state. A Lobster is a failure. Report it.
+**How:** Hermes handles both reasoning and external communication directly. No intermediary gateway. Two states: Online (Hermes running) or Dead (nothing running).
