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.
