+
+## Goal
+
+Install `@ai-hero/sandcastle` + ship `pnpm work dispatch` that picks the
+next ready AC bullet, prints the dispatch plan, and (with `--execute`)
+invokes sandcastle to run the implementer then reviewer.
+
+## Why
+
+The orchestrator closes the loop: docs/work/ tracks state, `.sandcastle/`
+holds the prompts, and dispatch.mjs connects them to sandcastle.
