A short bridge into the lessons
When studying a source reading, record its system/branch, test point and measurement reference, operating state and connection state. Mark any missing condition unknown before comparing it with an expected result.
Name the state
When studying a source reading, record its system/branch, test point and measurement reference, operating state and connection state. Mark any missing condition unknown before comparing it with an expected result.
Evidence & review

State the proof limit
End each note with what the evidence has not established. Returning communication is not the same observation as a completed repair.
