* test: focus assertions on behavioral evidence
Prune redundant and wording-coupled checks while retaining diagnostic, parser, recovery, and cleanup coverage.
* refactor: remove test-only wrappers and duplicate checks
Exercise production operations through test fixtures, remove unused adapters, and keep managed-member uncertainty guidance under its existing owner.
* test: focus process validation on diagnostic facts
* refactor: remove test-only runtime helpers
Move semantic evidence fixture setup out of runtime and remove unused Windows settle recovery helpers while checking configured defaults independently.
* test: focus artifact diagnostics on format facts
* test: verify retained cleanup guidance delivery
Carry descriptor outcomes, cancellation, retention and physical origin as named facts so wrappers cannot drop ownership context. Replace raw primary failure unwrapping with provenance facts across artifact consumers, and use Result for Kuna span reads including undefined rejections.
Exercise actual descriptors, rollback, cancellation and cleanup retry; update brittle snapshot and completion fixtures to use their producing boundaries.
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.
