Unit Executor

The leading principle is atomicity: one invocation owns one Unit Attempt and either commits one accepted Completion or records one diagnosable block. It never starts a second Unit.

Inputs

• UNITS.csv and the selected Unit row.
• Files declared by that row's inputs field.
• DECISIONS.md when the Unit is checkpoint-gated.

Outputs

• Files declared by the Unit's outputs field.
• Updated UNITS.csv, Run Evidence, and optional STATUS.md projection.
• output/QUALITY_GATE.md when strict quality checks block Completion.
