# Phase 142 Summary

Status: implemented on `main`

## Goal

Pilot the M2F-style two-stage pattern inside AITP by making statement
compilation explicit before proof repair, while keeping the packet
proof-assistant agnostic and still feeding the existing Lean bridge.

## What Landed

- a new support module:
  `research/knowledge-hub/knowledge_hub/statement_compilation_support.py`
- a new production CLI/service path:
  `aitp statement-compilation --topic-slug <topic_slug> --candidate-id <candidate_id>`
- new candidate-scoped artifacts under:
  `validation/topics/<topic_slug>/runs/<run_id>/statement-compilation/<candidate_slug>/`
  - `statement_compilation.json|md`
  - `proof_repair_plan.json|md`
- a new runtime active index:
  - `runtime/topics/<topic_slug>/statement_compilation.active.json|md`
- the statement-compilation packet now:
  - compiles one bounded declaration skeleton from the candidate/theory-packet inputs
  - records explicit temporary proof holes
  - names downstream targets such as `lean4` and `symbolic_checker`
  - stays explicit that proof repair is a separate stage
- `prepare_lean_bridge()` now consumes the compiled statement packet and repair
  plan instead of hiding the Stage 1 skeleton inside the Lean packet itself
- runtime/dashboard/docs/acceptance coverage now surface statement compilation
  as a first-class pre-Lean step

## Outcome

Phase `142` is complete.
All planned phases inside `v1.68` are now implemented and verified.
