3. Explain mechanism and competing hypotheses.
4. Request proving artifact packet.
5. Propose bounded fix with owner.

Silicon bring-up deep dive

Silicon bring-up quality comes from reproducible evidence, disciplined experiment control, and explicit owner-driven closure.

Concept diagram

symptom -> reproduce -> instrument -> isolate -> validate

Metric graph

reproducibility and recurrence trend

Metrics and artifacts to collect

• failure classifier

• evidence packet quality

• before-after validation matrix

Mini case study

Freeze context first, then prove one root-cause class before broad mitigation.

Debug branches

• Classify failure

• Collect decisive evidence

• Apply bounded fix

Senior review question

Ask: what is the first failing boundary, which artifact proves it, and who owns bounded closure?
