Use JSON.parse directly in package verification and retain one parsed Cursor recovery snapshot. Route native command source loading through the shared transform-service owner so completed command cleanup leaves no transform child.
Preserve JSONC validation and caller inputs. Cover the actual public source-loading lifecycle with an authored command and verified process lineage.
Move command and retained resource lifetimes into a shared verifier owner, keeping package workspace release as a separate dependency. Migrate Pi and Hermes verification to that owner while preserving open pipes, explicit EOF, diagnostics, and retained labs.
Require positive writable finalization before accepting EOF delivery. Cover premature close, opaque failures, late ownership delivery, mixed cleanup outcomes, exact retry, and real descendant cleanup with authored process boundaries.
