# v1.92 Milestone Audit

Status: passed

## Scope Closed

- Phase `166`: Public Front Door L0 Source Handoff
- Phase `166.1`: Contentful Source Registration Default

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-L0HAND-01` satisfied
  - a fresh public bootstrap now names concrete `L0` source-acquisition entry
    surfaces instead of generic prose
  - evidence:
    - `.planning/phases/166-public-front-door-l0-source-handoff/166-01-SUMMARY.md`
    - `research/knowledge-hub/tests/test_aitp_mcp_server.py`
    - `research/knowledge-hub/runtime/scripts/orchestrate_topic.py`
- `REQ-L0HAND-02` satisfied
  - `status`, `runtime_protocol`, and `replay-topic` now expose the same shared
    `l0_source_handoff` truth surface
  - evidence:
    - `.planning/phases/166-public-front-door-l0-source-handoff/166-VERIFICATION.md`
    - `research/knowledge-hub/tests/test_aitp_service.py`
    - `research/knowledge-hub/tests/test_topic_replay.py`
- `REQ-L0HAND-03` satisfied
  - direct and discovery-driven arXiv registration now attempt content
    acquisition by default, while preserving `--metadata-only` as the explicit
    lightweight path
  - evidence:
    - `.planning/phases/166.1-contentful-source-registration-default/166.1-01-SUMMARY.md`
    - `research/knowledge-hub/source-layer/scripts/register_arxiv_source.py`
    - `research/knowledge-hub/source-layer/scripts/discover_and_register.py`
- `REQ-VERIFY-01` satisfied
  - the milestone now has one bounded fresh-topic proof of
    `bootstrap -> concrete source handoff -> registration` on the real
    repository kernel root
  - evidence:
    - `.planning/phases/166.1-contentful-source-registration-default/166.1-VERIFICATION.md`
    - `.planning/phases/166.1-contentful-source-registration-default/evidence/jones-chapter-4-source-registration-proof-20260413/proof.json`
    - `research/knowledge-hub/runtime/scripts/run_first_run_topic_acceptance.py`

## Cross-Phase Integration Check

Cross-phase integration passed:

- Phase `166` surfaces the concrete `L0` handoff at the exact public front-door
  point where a fresh topic returns to missing-source recovery
- Phase `166.1` makes the direct registration surface and the discovery bridge
  honor that same operator story instead of falling back to metadata-only
  semantics
- the real-kernel fresh-topic proof confirms the two phases now compose into
  one coherent user flow:
  `bootstrap -> concrete handoff -> registration`

## Verification Evidence

- `python -m pytest research/knowledge-hub/tests/test_aitp_mcp_server.py research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_topic_replay.py -q`
  - result: `157 passed`
- `python -m pytest research/knowledge-hub/tests/test_aitp_mcp_server.py research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_topic_replay.py research/knowledge-hub/tests/test_runtime_scripts.py -q`
  - result: `223 passed`
- `python -m pytest research/knowledge-hub/tests/test_schema_contracts.py -q`
  - result: `11 passed`
- `python -m pytest research/knowledge-hub/tests/test_source_discovery_contracts.py research/knowledge-hub/tests/test_aitp_cli_e2e.py research/knowledge-hub/tests/test_runtime_scripts.py -q`
  - result: `105 passed`
- `python research/knowledge-hub/runtime/scripts/run_first_run_topic_acceptance.py --json`
  - result: `success` on isolated temp kernel root
- real-kernel proof command recorded in
  `.planning/phases/166.1-contentful-source-registration-default/evidence/jones-chapter-4-source-registration-proof-20260413/COMMANDS.md`
  - result: `success`
  - `download_status = downloaded`
  - `extraction_status = extracted`

## Accepted Open Gaps

- broader `L0` discovery/provider expansion remains deferred beyond the shipped
  arXiv-first entry surfaces
- automatic source acquisition from the runtime queue remains explicitly out of
  scope
- wider HCI, recovery, and collaboration backlog items remain in
  `.planning/BACKLOG.md` for future milestone promotion
