# Roadmap: v1.43 Unified Control Plane And Paired-Backend Closure

## Overview

`v1.43` is shipped.

It froze AITP's control-plane semantics and paired-backend governance as one
bounded operator surface across runtime, CLI, doctor, docs, and real-topic
verification.

## Phases

- [x] **Phase 54: Control-Plane Ontology Freeze And Runtime Contracts**
  - Goal: make `task_type`, `lane`, `layer`, `mode`, and `H-plane` explicit,
    distinct, and inspectable through runtime/service/CLI surfaces.
  - Outcome: one bounded control-plane contract surface exists in production
    code and is reflected in runtime truth, status, and doctor surfaces.

- [x] **Phase 55: Paired-Backend Alignment And Drift Audit**
  - Goal: add explicit paired-backend alignment state, drift semantics, and
    maintenance/audit entrypoints.
  - Outcome: typed and operator-primary backends can be checked for alignment
    without conflating consultation, promotion, and sync semantics.

- [x] **Phase 56: H-Plane Steering And Approval Surface Consolidation**
  - Goal: consolidate redirect, pause, approve, and override into durable
    `H-plane` artifacts and entrypoints instead of scattered runtime notes.
  - Outcome: operator steering becomes a first-class cross-layer surface.

- [x] **Phase 57: Control-Plane Docs, Doctor Parity, And Regression Closure**
  - Goal: close the milestone with non-mocked proof across docs, doctor/status
    surfaces, and at least one real control-plane/paired-backend verification
    flow.
  - Outcome: the control plane and paired-backend governance can be resumed and
    audited from disk like the rest of AITP.

## Key Accomplishments

1. Added an explicit control-plane runtime surface plus `doctor` parity for the
   same architecture/governance contract.
2. Added paired-backend audit and `H-plane` audit entrypoints with durable
   runtime artifacts.
3. Closed the milestone with a real thesis-backed control-plane acceptance
   route instead of mock-only proof.
