Why a 5 Whys investigation can branch
A passing test can still miss the failure it was meant to prevent. Use the 5 Whys to find a mechanism you can examine, rather than a chain that merely fills five boxes.

Power and cooling affect the work a GPU pool can sustain. Device signals, request completions and queue growth help distinguish a physical limit from a workload change.
A rollback exception tests whether Opus 4.6 preserves decisive evidence across a long session, and whether the resulting answer arrives in time to help.
A rollback proposal crosses from recorded evidence into a changing system. The handoff carries source references, current preconditions and unfinished actions.
Alert correlation can reduce repeated investigation, but a group must still expose independently actionable symptoms after one member is fixed.
Start with the affected operation, keep its population and time window visible, and carry that context into resource queries, logs and traces.
Fast model loading and successful checkpoint recovery test different storage paths. Compare both before adopting an AI storage configuration.
A reusable prompt connects observations, competing explanations and the next read-only check, so an incomplete record can still support useful investigation.
A service cannot write its file, even though the disk looks fine. Follow the directories, mounts and permissions that determine which storage it actually sees.
Use process-level evidence and a comparable workload to test a bottleneck, then keep the setting only if its user-facing tradeoff is understood.
Incident channels connect responders to decisions and results. Write-capable bots also need precise action identifiers, duplicate handling and a route around a chat outage.
Test detection, grouping, investigation, routing or repair on your own cases, then include the corrections and upkeep that remain after the demonstration.
