Resolve raw input at the application boundary and reuse its facts in both MCP admission paths. Keep cleanup, mutation retirement and execution ordering while retaining structured correction details for rejected commands.
Validation: 186 focused tests, source checks, docs conformance and duplication gate passed. The new compiled CLI regression fails on the main baseline. Provider process controls use deterministic fixtures; no real Rizin verification is claimed.
Retain process input and unexpected failure diagnostics through the shared error projector. Preserve filesystem causes and firmware validation issues, and mark unchanged invalid requests nonretryable.
Use typed stat settlement and parse unknown command failures without losing null or undefined rejection causes.
