Directed Fuzzball team to improve logging and error observability

February 20, 2026 at 12:37 AMtechnicalmedium

Situation

After AMD MI300 troubleshooting meeting, directed Fuzzball team (Jonathon Anderson, David Horn) that the product needs better logging and error visibility. Customers should be able to self-diagnose issues via log files instead of requiring live troubleshooting meetings with CIQ engineers.

Reasoning

AMD troubleshooting meeting crystallized a broader concern: Fuzzball's error reporting is insufficient. If a customer can't figure out what's wrong without a live call, that doesn't scale. Pushing for self-diagnosing product — log files should tell the story. Both a product maturity requirement and a scaling strategy. The principle 'Don't mind a problem. Mind a problem when there's no clear visibility' is meant to be embedded in how the team builds.

Additional Context

AMD MI300 imaging failure was caused by two missing config files. Root cause was found during live troubleshooting meeting — this should have been diagnosable from logs. Peter sent the same message to both Jonathon Anderson and David Horn to ensure the message landed with key Fuzzball team members.

Observed Evidence

Same directive sent to two different Fuzzball team members in parallel DMs. Direct quote establishes a principle, not just a one-time fix. AMD meeting context shows the specific gap that triggered the directive.

Reasoning Depth Analysis

Org Signal:Product maturity means customers can self-serve diagnostics — features without observability are incomplete
Who Affected:AMD (customer experience), all future Fuzzball customers, Chris Wolford's entire PIC team
Precedent:Fuzzball must invest in observability alongside features — logging is not optional
Consequences:Reduces support burden, improves customer experience, enables scaling without proportional engineer time
Timing:Directly after AMD troubleshooting meeting made the gap visible — striking while the lesson is fresh

Dont mind a problem. Mind a problem when theres no clear visibility into what the problem is. Instead of having this meeting, AMD should be able to send us a log file that makes clear EXACTLY whats going on.

I need Andersen to hear and understand how we are failing to provide logging/output in fuzzball that makes clear where problems are when they are encountered.

Node imaging failure traced to two missing config files. Manually adding them immediately enabled Substrate to detect MI300 GPUs.
