# Phase 60 Summary

Status: implemented on `main`

## Goal

Prove that one bounded MVP `L2` direction is operational through compiled,
hygiene, and isolated acceptance surfaces.

## What Landed

- new extracted command-family handler:
  `research/knowledge-hub/knowledge_hub/cli_l2_compiler_handler.py`
- `AITPService.compile_l2_workspace_map()` now exposes the compiled L2 memory
  map through the public service facade
- `AITPService.audit_l2_hygiene()` now exposes the bounded hygiene report
  through the public service facade
- CLI now exposes:
  - `aitp compile-l2-map`
  - `aitp audit-l2-hygiene`
- new isolated non-mocked acceptance:
  `research/knowledge-hub/runtime/scripts/run_l2_mvp_direction_acceptance.py`
  seeds the TFIM MVP direction on a temp kernel root, consults the seeded
  `physical_picture`, compiles the workspace map, audits hygiene, and verifies
  the durable artifacts

## Outcome

Phase `60` is complete.
The next active milestone step is Phase `61`
`l2-mvp-docs-acceptance-and-regression-closure`.
