# Phase 124 Summary

Status: implemented on `main`

## Goal

Lock the bounded method-specificity contract before production code lands.

## What Landed

- contract coverage for `method_specificity_rows` across source distillation,
  topic shell, runtime bundle, status E2E, schemas, and docs
- a new documentation contract test file:
  `research/knowledge-hub/tests/test_l1_method_specificity_contracts.py`
- a failing-then-passing acceptance contract for the new runtime surface

## Outcome

Phase `124` is complete.
`v1.64` has a real contract for the L1 method-specificity surface.
