# Phase 168.1 Verification

## Goal Verdict

Passed. The phase goal was to surface the richer analytical cross-check
contract on runtime/read-path surfaces and close the milestone with one bounded
analytical proof lane. `validation_review_bundle` now exposes a structured
analytical cross-check surface, the machine and human runtime paths render it,
and the milestone now has a dedicated isolated acceptance lane while the older
analytical judgment acceptance remains compatible.

## Must-Haves

- [x] status, runtime protocol, and the primary analytical review bundle expose
  the same bounded analytical cross-check surface
- [x] the richer analytical runtime surface is structured and machine-readable,
  not only prose
- [x] the milestone closes with one dedicated analytical cross-check proof lane
  while keeping the older analytical judgment lane green

## Evidence

- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py::AITPServiceTests::test_prepare_verification_analytical_uses_analytical_review_as_primary_bundle research/knowledge-hub/tests/test_schema_contracts.py -q`
  - `12 passed`
- `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -k "analytical_cross_check_surface_acceptance or analytical_judgment_surface_acceptance" -q`
  - `2 passed`
- `python research/knowledge-hub/runtime/scripts/run_analytical_cross_check_surface_acceptance.py --json`
  - `success`
- `python research/knowledge-hub/runtime/scripts/run_analytical_judgment_surface_acceptance.py --json`
  - `success`

## Notes

- the new runtime surface stays nested under the existing
  `validation_review_bundle` contract instead of creating a parallel runtime
  family
- `validation_review_bundle.active.md` remains the primary analytical read path
  and now renders the same bounded surface visible in status/runtime JSON
- `v1.94` phase work is complete; the next workflow step is milestone audit and
  archive
