## Rule

**Info**. ReadProtection is declared on a sealed/static non-command type,
Unprotected is declared on a provably non-model parameter, or Off repeats an
already-Off assembly policy.

## Resolve the diagnostic

Remove the inert declaration, or place it on the intended command, assembly,
read-model parameter or model. Non-sealed bases are allowed to carry an inherited
ReadProtection declaration even when the base itself has no Handle method.

Off on a ProtectedDecision command in an On assembly is **not** redundant:
it preserves the explicit protected-decision behavior instead of enforcing On.
On on a ProtectedDecision command is **not** redundant: it enables read-model
parameters and validator constructor reads and changes conflict diagnostics.
Neither combination is reported as inert. ProtectedDecision also retains its
explicit decision policy if an operational cap lowers On.

No automatic removal is offered because changing rollout policy deserves review.
