Test Coverage Notes

• Reviewed tests/unit/cli/test_run_qa.py, including coverage that fresh runs default fat-harness off and only explicit seed.orchestrator.execution_mode: fat_harness enables it.
• Attempted python -m pytest tests/unit/cli/test_run_qa.py; blocked because python is unavailable.
• Attempted python3 -m pytest tests/unit/cli/test_run_qa.py; blocked because pytest is not installed.

Design Notes

The change is limited to CLI debug text. Current source shows fat-harness remains opt-in via _resolve_fat_harness_mode, so removing “(default)” matches runtime behavior.

Design / Roadmap Gate

Affected boundary is the ouroboros run --debug status output only. The resolver still returns False for missing or blank execution mode and True only for explicit fat_harness; runner construction still receives the resolved boolean unchanged.

Directional Notes

Focused on runtime reality versus operator-facing CLI output, because misleading execution-mode text can cause incorrect operational assumptions. No blocker was found.

Test Coverage

• Reviewed tests/unit/cli/test_run_qa.py, including coverage that fresh runs default fat-harness off and only explicit seed.orchestrator.execution_mode: fat_harness enables it.
• Attempted python -m pytest tests/unit/cli/test_run_qa.py; blocked because python is unavailable.
• Attempted python3 -m pytest tests/unit/cli/test_run_qa.py; blocked because pytest is not installed.

Merge Recommendation

Approve. This is a narrowly scoped correction to misleading debug output, with surrounding source and existing tests supporting the intended contract.
