Preserve observations
PSU curve, voltage, GR, USB state, scope trace, logs and photographs should be recorded before interpretation.
Capture what the phone did, what was measured, what hypothesis was tested, what repair was performed and what post-repair evidence actually confirmed.
A case is marked confirmed only when the final result is supported by a specific isolation or before/after test.
The uploaded V1 categories are preserved and expanded into a technician-first archive.
Sample records from the uploaded V1 are retained as source-derived examples. V2 explicitly marks whether each causal conclusion was directly confirmed or merely inferred.
| Rail / Test Point | Before | Source Reference | After Repair | Evidence Interpretation |

V2 expands the original logger so symptom, measurements, hypothesis, confirmation and final verification are stored separately.
The original source labels the archive “verified.” V2 defines what that should mean operationally.
PSU curve, voltage, GR, USB state, scope trace, logs and photographs should be recorded before interpretation.
A current signature or one abnormal rail can suggest a domain without proving the failed component.
Known-good substitution, line isolation, component removal, direct access or repeatable before/after evidence should narrow the cause.
The strongest archive records show the failed measurement returning to normal together with functional recovery.
