Use when: Researching component markings online, interpreting datasheets, updating diagnosis results, and writing the final troubleshooting report. Combines research findings with measurement results into a final diagnosis and repair recommendation. Datenblatt-Recherche, Bauteil identifizieren, Abschlussbericht, Diagnose-Update, final report, repair recommendation, Reparaturempfehlung.
<skill_purpose> Grounds the diagnosis in verifiable component data: searches for datasheets, verifies pinouts and typical application schematics, reconciles research with prior measurements, and produces a final actionable report. </skill_purpose>
<input> - Component inventory with markings (from `board_image_intake` or equivalent) - Fault hypotheses with priority ranking (from `fault_hypothesis_engine` or equivalent) - Measurement results (from user-provided data or `multimeter_test_planner` execution) - Optional: Specific component markings to prioritize for research </input> <instructions> 1. Search for each unverified component marking using web search and datasheet sources. Run parallel searches for independent components. 2. Verify pinouts and typical application circuits — confirm that the assumed component function matches actual package behavior from the datasheet. 3. Update the diagnosis: for each prior hypothesis, determine if it is now Confirmed, Refuted, or Still Open based on research and measurement data. 4. Synthesize all evidence into a final ranked diagnosis with an explicit confidence percentage. 5. Create a simplified text-based functional sketch (ASCII block diagram) of the circuit with the suspected fault location marked. </instructions><output_format>

Per component researched, use this table:
| Component | Marking | Identified As | Package Match | Datasheet Source | Confidence |
|---|---|---|---|---|---|
| U1 | TP4056 | Li-Ion charge IC (TPOWER/TOPPOWER) | SOT-23-8 ✓ | lcsc.com / datasheet PDF | Confirmed |
| Q1 | S8050 | NPN BJT 25V/500mA (SANYO) | SOT-23 ✓ | datasheet PDF | Confirmed |
| IC2 | "A3C" | Unresolved — 3 candidates found | SOT-23-5 | — | Unclear |
Classification for each component:

Updated hypothesis status after research and measurements:
| Hypothesis | Status | Evidence Basis | Updated Confidence |
|---|---|---|---|
| H1: Cold solder at J1 | Confirmed | Measurement 1: 0.4V drop under load [Messung] | 90% |
| H2: Degraded battery | Refuted | Cell voltage drop only 0.05V under load [Messung] | — |
| H3: SW1 contact fault | Still Open | Not yet measured | — |
