# Phase 57 Summary

Status: implemented on `main`

## Goal

Close `v1.43` with doctor parity, public-doc parity, and one non-mocked
real-topic verification flow for the new control-plane and paired-backend
surfaces.

## What Landed

- `aitp doctor --json` now exposes explicit `control_plane_contracts` and
  `control_plane_surfaces` sections through
  `research/knowledge-hub/knowledge_hub/frontdoor_support.py`
- root README, kernel README, and install docs now name the bounded
  control-plane audit path directly:
  - `aitp capability-audit`
  - `aitp paired-backend-audit`
  - `aitp h-plane-audit`
- maintainability docs now also point at the extracted helper modules:
  - `control_plane_support.py`
  - `paired_backend_support.py`
  - `h_plane_support.py`
- new real-topic acceptance:
  `research/knowledge-hub/runtime/scripts/run_scrpa_control_plane_acceptance.py`
  proves doctor, status, capability, paired-backend, and `H-plane` surfaces on
  a thesis-backed scRPA topic

## Outcome

Phase `57` is complete.
Milestone `v1.43` `Unified Control Plane And Paired-Backend Closure` is now
closed and ready to hand off to the next milestone selection step.
