## Pre-build acceptance observation
- RED: architecture-boundaries (ARCHITECTURE.md)
  intent: The implementation exposes separate block, inline, rendering, and executable boundaries.
  return code: 1
  stderr:
    Traceback (most recent call last):
      File "architecture-boundaries.py", line 8, in <module>
        assert all(path.exists() for path in required)
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    AssertionError
- RED: architecture-runtime-contract (ARCHITECTURE.md)
  intent: The runtime contains the required POSIX conformance wrapper boundary.
  return code: 1
  stderr:
    Traceback (most recent call last):
      File "architecture-runtime-contract.py", line 4, in <module>
        assert wrapper.is_file()
