# v1.93 Milestone Audit

Status: passed

## Scope Closed

- Phase `167`: L1 Contradiction Intake Rows And Comparison Basis
- Phase `167.1`: Contradiction Runtime Surface And Proof Lane

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-L1CON-01` satisfied
  - `L1` intake now records richer contradiction rows instead of leaving
    contradiction visibility as a thin warning candidate
  - evidence:
    - `.planning/phases/167-l1-contradiction-intake-rows-and-comparison-basis/167-01-SUMMARY.md`
    - `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py`
    - `research/knowledge-hub/tests/test_aitp_service.py`
- `REQ-L1CON-02` satisfied
  - contradiction rows now carry bounded comparison basis, side-specific
    summaries, and evidence excerpts
  - evidence:
    - `.planning/phases/167-l1-contradiction-intake-rows-and-comparison-basis/167-VERIFICATION.md`
    - `schemas/research-question.schema.json`
    - `schemas/topic-synopsis.schema.json`
- `REQ-L1CON-03` satisfied
  - runtime/read-path surfaces now expose the richer contradiction surface
    across `status`, `runtime_protocol`, dashboard, and `L1` vault source-intake
  - evidence:
    - `.planning/phases/167.1-contradiction-runtime-surface-and-proof-lane/167.1-01-SUMMARY.md`
    - `research/knowledge-hub/knowledge_hub/runtime_read_path_support.py`
    - `research/knowledge-hub/knowledge_hub/l1_vault_support.py`
- `REQ-VERIFY-01` satisfied
  - the milestone now has one dedicated contradiction-aware proof lane
  - evidence:
    - `.planning/phases/167.1-contradiction-runtime-surface-and-proof-lane/167.1-VERIFICATION.md`
    - `research/knowledge-hub/runtime/scripts/run_l1_contradiction_surface_acceptance.py`

## Cross-Phase Integration Check

Cross-phase integration passed:

- Phase `167` upgraded the contradiction-row truth contract without breaking the
  existing contradiction-aware acceptance lane
- Phase `167.1` reused that richer truth surface directly in runtime/read-path
  renderers instead of re-deriving contradiction logic ad hoc
- the dedicated contradiction-surface proof lane confirms the milestone now has
  one coherent contradiction-aware `L1` intake story

  - result: `15 passed`

## Accepted Open Gaps

- full scientific adjudication of which source is correct remains deferred
- automatic queue-level contradiction rerouting remains deferred
- broader `L4` analytical validation and post-contradiction reasoning remain
  open for later milestone promotion
