Agent Reliability Harness v7.2.0
Summary
Agent Reliability Harness v7.2.0 makes Production State Witness a runtime-enforced control loop for state/UI/async/concurrency work.
Changes
- Added
state_witness.mdschema and semantic checker with real call-chain/source-locator requirements. - Added reachable failing/fixed/preserved state rows with observed-before/expected-after values and executable evidence locators.
- Added controller gates for
seal,run-set dispatched,dispatch-create,validate, and protected acceptance. - Added
witness-setfor independent review evidence andpolicy/flow/user_visibleverification tiers. - Added sealed witness digests and post-seal mutation detection.
- Updated Full/Lite/worker/evaluator templates, protocol docs, evaluation cases, scoring, packaging, and bilingual release history.
- Added regression coverage for hollow witnesses, mismatched production states, missing seal, insufficient verification tier, post-seal mutation, and the complete stateful acceptance path.
Verification
- State Witness regression: 11 tests passed.
- Runtime regression: all checks passed.
- Runtime package/source verification: passed.
- Installed skill package drift check: passed.
- Protocol score: 100/A.
- Python compilation and
git diff --check: passed.
Boundary
The harness validates the evidence contract and controller transitions. Actual Xcode/device user-visible evidence remains required for app-specific acceptance.
