# Phase 148 Verification

## Status

passed

## Verification Evidence

- contract + documentation slice:
  - `python -m pytest research/knowledge-hub/tests/test_hypothesis_branch_routing_contracts.py -q`
  - result: `2 passed`
- schema slice:
  - `python -m pytest research/knowledge-hub/tests/test_schema_contracts.py -q`
  - result: `10 passed`
- replay slice:
  - `python -m pytest research/knowledge-hub/tests/test_topic_replay.py -q`
  - result: `2 passed`
- isolated acceptance:
  - `python research/knowledge-hub/runtime/scripts/run_hypothesis_branch_routing_acceptance.py --json`
  - result: `success`
  - checks:
    - active branch hypothesis id: `hypothesis:weak-coupling`
    - deferred branch hypothesis ids: `hypothesis:symmetry-breaking`
    - follow-up branch hypothesis ids: `hypothesis:prior-work`
    - follow-up subtopic count: `1`
- runtime acceptance harness slice:
  - `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -k "hypothesis_branch_routing_acceptance" -q`
  - result: `1 passed, 33 deselected`
- backward-compatibility slices:
  - `python -m pytest research/knowledge-hub/tests/test_competing_hypotheses_contracts.py -q`
  - result: `2 passed`
  - `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -k "runtime_protocol_bundle_matches_public_schema or topic_status_and_prepare_verification_surface_new_shell_fields" -q`
  - result: `1 passed, 129 deselected`
  - `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py -k "projection_helpers_write_valid_outputs" -q`
  - result: `1 passed, 12 deselected`

## Notes

- Verification stayed intentionally targeted to the new hypothesis-routing
  surface and its immediate replay/runtime/schema dependencies.
- No full knowledge-hub suite rerun was performed in this step because the repo
  still contains unrelated in-flight working-tree changes outside Phase `148`.
