Remaining scope

Removed CommandShimReplay, LoopbackReplayRecorder, ProcessCheckpoints and related replay paths are no longer in scope. Live work remains in process ownership observations, reference reads, provider/application target resolution and leases, and CLI error projection. Preserve actual causes and distinguish cancellation, invalid input, unavailable dependencies, and normal process disappearance. Do not replace every catch or invariant throw mechanically, and do not hide useful local diagnostics.

Verification

Exercise representative valid and malformed producer data through the consumer boundary and assert the resulting observations, unknowns, or actionable failure. Keep CLI/MCP behavior aligned where applicable.

This scope was refreshed after removal of replay and permission plumbing and merge of PR #538; implementation is being addressed in the boundary root-cause cleanup.
