# v1.86 Milestone Audit

Status: passed

## Scope Closed

- Phase `160`: Hypothesis Route Transition Clearance Surface

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-HCLEAR-01` satisfied
  - runtime surfaces now materialize one bounded transition-clearance summary
    from route transition escalation plus operator-checkpoint lifecycle context
  - evidence:
    - `research/knowledge-hub/knowledge_hub/runtime_read_path_support.py`
    - `research/knowledge-hub/knowledge_hub/runtime_bundle_support.py`
    - `research/knowledge-hub/runtime/schemas/progressive-disclosure-runtime-bundle.schema.json`
- `REQ-HCLEAR-02` satisfied
  - replay and read-path surfaces now expose the bounded clearance decision
    directly
  - evidence:
    - `research/knowledge-hub/knowledge_hub/topic_replay.py`
    - `research/knowledge-hub/tests/test_topic_replay.py`
    - `research/knowledge-hub/tests/test_hypothesis_route_transition_clearance_contracts.py`
- `REQ-HCLEAR-03` satisfied
  - the route transition-clearance surface now coexists with route transition
    escalation and helper mechanisms instead of replacing them
  - evidence:
    - `research/knowledge-hub/runtime/scripts/run_hypothesis_route_transition_clearance_acceptance.py`
    - `research/knowledge-hub/tests/test_runtime_scripts.py -k "hypothesis_route_transition_clearance_acceptance" -q`
- `REQ-VERIFY-01` satisfied
  - the milestone closes with one isolated route transition-clearance
    acceptance lane plus targeted regression coverage
  - evidence:
    - `research/knowledge-hub/runtime/scripts/run_hypothesis_route_transition_clearance_acceptance.py --json`
    - `research/knowledge-hub/tests/test_schema_contracts.py -q`
    - `research/knowledge-hub/tests/test_aitp_service.py -k materialize_runtime_protocol_bundle_writes_expected_artifacts -q`

## Cross-Surface Integration Check

The milestone is single-phase, so the integration audit is cross-surface rather
than cross-phase:

- runtime bundle integration passed
  - `status --json` now exposes
    `active_research_contract.route_transition_clearance` with explicit
    clearance status, checkpoint lifecycle state, and follow-through ref
- runtime protocol integration passed
  - `runtime_protocol.generated.md` now renders `## Route transition clearance`
- replay integration passed
  - `replay-topic --json` now surfaces the same transition-clearance payload
    and clearance status
- coexistence integration passed
  - the bounded acceptance lane proves route transition clearance, route
    transition escalation, and helper mechanisms can coexist without fresh
    runtime mutation
- docs/test integration passed
  - kernel README, runtime README, and the runbook all reference the new route
    transition-clearance acceptance lane and surface

## Verification Evidence

- `python -m compileall research/knowledge-hub/knowledge_hub/runtime_read_path_support.py research/knowledge-hub/knowledge_hub/kernel_markdown_renderers.py research/knowledge-hub/knowledge_hub/runtime_bundle_support.py research/knowledge-hub/knowledge_hub/topic_replay.py research/knowledge-hub/runtime/schemas/progressive-disclosure-runtime-bundle.schema.json research/knowledge-hub/tests/test_hypothesis_route_transition_clearance_contracts.py research/knowledge-hub/runtime/scripts/run_hypothesis_route_transition_clearance_acceptance.py research/knowledge-hub/tests/test_topic_replay.py research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_runtime_scripts.py`
  - result: `compiled successfully`
- `python -m pytest research/knowledge-hub/tests/test_hypothesis_route_transition_clearance_contracts.py -q`
  - result: `4 passed`
- `python -m pytest research/knowledge-hub/tests/test_topic_replay.py research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_runtime_scripts.py -q`
  - result: `58 passed`
- `python research/knowledge-hub/runtime/scripts/run_hypothesis_route_transition_clearance_acceptance.py --json`
  - result: `success`
- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -k materialize_runtime_protocol_bundle_writes_expected_artifacts -q`
  - result: `1 passed, 129 deselected`
- `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py -k "source_intelligence_into_read_path" -q`
  - result: `1 passed, 12 deselected`

## Accepted Open Gaps

- explicit route-transition follow-through after clearance remains deferred
  beyond the transition-clearance surface
- automatic route commit and follow-up runtime mutation remain deferred beyond
  this milestone
- no broader full-suite rerun was attempted because unrelated in-flight
  working-tree changes remain present outside the `v1.86` slice
