# Phase 94 Summary

Status: implemented on `main`

## Goal

Lock the subprocess failure contract so operator-facing errors keep command and
return-code context.

## What Landed

- new contract test:
  `research/knowledge-hub/tests/test_subprocess_error_contracts.py`

## Outcome

Phase `94` is complete.
`v1.54` is active on a subprocess diagnostics contract baseline.
