Tag physical read outcomes at the owning boundary and preserve opaque caller cancellation reasons through JSON pipelines and reference imports. Share named bounded-read options across consumers and retain failed cleanup ownership for retry.
Closes#5686
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.
Refs #5397, #5401, #5402, #5642
Add shared, typed input-contract and timeout-state recovery guidance. Normalize SDK input failures within the actual MCP wire budget, preserve full diagnostics and protocol metadata, and retain original Evidence when normalized delivery would exceed the budget.
Fixes#5431.
Keep failed JSON read handles in the existing server resource scope and fail admission until cleanup succeeds. Thread cancellation through every process CLI input read and replace timer-driven cancellation checks with a shared first-read gate.
Classify authenticated standalone Evidence as wrong-kind input while preserving tampered-record integrity failures and actionable messages across ledger, CLI, and MCP consumers. Record unrelated CS_RESTRICT process neighbors as unverified without weakening related-process ownership checks. Update stale ADB fixtures for the actual shell protocol.
Validated focused CLI, MCP, filesystem, ownership, and error projection tests; static, docs, and duplication gates pass. The host-level CS_RESTRICT load reproduction was not run. Refs #2050, #2035, #2064.
