# v1.68 Milestone Audit

Status: passed

## Scope Closed

- Phase `138`: Knowledge Compilation Contract
- Phase `139`: Compiled Knowledge Surface And Acceptance
- Phase `140`: Closure And Regression Audit
- Phase `141`: L1 Three-Layer Vault And Flowback
- Phase `142`: M2F Statement-Compilation Pilot

## Production Outcome

`v1.68` now exposes one bounded persistent research-brain and pre-formalization
surface through:

- `research/knowledge-hub/knowledge_hub/l2_compiler.py`
- `research/knowledge-hub/knowledge_hub/l1_vault_support.py`
- `research/knowledge-hub/knowledge_hub/statement_compilation_support.py`
- `research/knowledge-hub/runtime/scripts/run_l2_knowledge_report_acceptance.py`
- `research/knowledge-hub/runtime/scripts/run_l1_vault_acceptance.py`
- `research/knowledge-hub/runtime/scripts/run_statement_compilation_acceptance.py`
- `research/knowledge-hub/runtime/README.md`
- `research/knowledge-hub/runtime/AITP_TEST_RUNBOOK.md`

The milestone adds:

- one explicit non-authoritative compiled-knowledge contract over canonical and
  staging `L2`
- one dedicated bounded acceptance lane for the compiled-knowledge report
- one topic-scoped `L1` raw/wiki/output vault with explicit flowback
- one explicit pre-Lean statement-compilation surface plus proof-repair plan
  that the downstream Lean bridge now consumes

## Verification Evidence

- compiled-knowledge CLI / contract / acceptance slices:
  - `python -m pytest research/knowledge-hub/tests/test_aitp_cli.py -q -k "compile_l2_knowledge_report or compile_l2_graph_report or compile_l2_map"`
  - `python -m pytest research/knowledge-hub/tests/test_l2_backend_contracts.py -q -k "knowledge_report or l2_mvp_commands_and_acceptance_are_documented"`
  - `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -q -k "knowledge_report"`
  - `python -m pytest research/knowledge-hub/tests/test_aitp_cli_e2e.py -q -k "compile_l2_knowledge_report_cli_json_path"`
  - `python research/knowledge-hub/runtime/scripts/run_l2_knowledge_report_acceptance.py --json`
- L1 vault slices:
  - `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -q -k "source_backed_l1_intake or l1_vault"`
  - `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -q -k "l1_vault_acceptance or l2_knowledge_report_acceptance_script_runs_on_isolated_work_root"`
  - `python -m pytest research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_l1_vault_contracts.py -q`
  - `python research/knowledge-hub/runtime/scripts/run_l1_vault_acceptance.py --json`
- statement-compilation pilot slices:
  - `python -m pytest research/knowledge-hub/tests/test_aitp_cli.py -q -k "statement_compilation or lean_bridge"`
  - `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -q -k "statement_compilation or lean_bridge_write_durable_artifacts"`
  - `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -q -k "statement_compilation_acceptance"`
  - `python -m pytest research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_statement_compilation_contracts.py -q`
  - `python research/knowledge-hub/runtime/scripts/run_statement_compilation_acceptance.py --json`

## Accepted Open Gaps

- `v1.68` intentionally did not close the Layer 0 discovery gap before source
  registration; that is promoted to the next milestone as Phase `143`.
- The statement-compilation pilot remains bounded and does not claim whole-paper
  or whole-topic automated formalization.
- Broader multi-user or research-utility validation remains outside milestone
  scope.
