# Phase 137 Summary

Status: implemented on `main`

## Goal

Close `v1.67` with one shared cross-runtime parity audit/report surface and one
bounded evidence set for Codex, Claude Code, and OpenCode.

## What Landed

- a new shared closure report script,
  `research/knowledge-hub/runtime/scripts/run_runtime_parity_audit.py`, now:
  - runs the Codex baseline plus the Claude Code and OpenCode bounded probes
  - emits one aggregate report across all three runtimes
  - names `equivalent_surfaces`, `degraded_surfaces`, and `open_gaps`
- a focused unit test now protects the audit summary semantics
- runtime/public docs now point operators to the shared closure audit command

## Outcome

Phase `137` is complete.
`v1.67` now has a complete bounded parity evidence chain: shared contract,
Codex baseline, Claude Code probe, OpenCode probe, and one honest closure
report. The next planning boundary is milestone completion.
