cjsFallbackHandler was a no-op pass-through returning only its last
argument, and state-command-router was its sole consumer — every handler
wrapped a thunk in a 5-arg projection tuple whose first four args
(registryCommand, registryArgs, legacyArgs, rawFormatter) were
constructed and immediately discarded (rawFormatter null at 100% of
sites). The SDK-dispatch path the metadata was nominally for is a retired
shim.
- Collapse all 20 state handlers to plain () => state.cmd*(...) thunks,
matching the post-#298 inline convention used by the verify/roadmap/
phases routers (complete-phase already used this form).
- Remove the local fallback() helper and Handler type from
state-command-router.cts.
- Drop cjsFallbackHandler from cjs-command-router-adapter.cts exports —
no remaining consumers.
Behavior-preserving: each thunk body is unchanged. No test referenced
cjsFallbackHandler. Adapter test (8/8), state-routing tests (36/36), and
the full unit suite (3435 pass / 0 fail) stay green.
