# Phase 167.1 Verification

## Goal Verdict

Passed. The phase goal was to expose the richer contradiction-row surface
across runtime/read-path outputs and close the milestone with one dedicated
contradiction-aware proof lane. The runtime/read-path contradiction surface now
shows comparison basis and side-specific summaries, and the dedicated proof
lane is green.

## Must-Haves

- [x] runtime/read-path surfaces expose the richer contradiction basis from
  Phase `167`
- [x] the `L1` vault source-intake page now keeps contradiction rows visible
- [x] one dedicated contradiction-aware proof lane closes the milestone

## Evidence

- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -k "persists_l1_conflict_candidates" -q`
  - `1 passed`
- `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -k "l1_contradiction_surface_acceptance" -q`
  - `1 passed`
- `python research/knowledge-hub/runtime/scripts/run_l1_contradiction_surface_acceptance.py --json`
  - `success`
- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_runtime_scripts.py -k "contradiction or l1_contradiction_surface_acceptance" -q`
  - `2 passed`

## Notes

- The new bounded proof lane is:
  `research/knowledge-hub/runtime/scripts/run_l1_contradiction_surface_acceptance.py`
- The older assumption/depth acceptance lane remains intact as a compatibility
  baseline.
