root-cause-tracing

Root cause tracing works by enforcing instrumentation and validation at each layer, then inspecting logs and stack traces backward from the symptom. This reveals the original trigger and prevents future recurrence.

Errors cascade through layers without proper validation at each level. Adding structured instrumentation and validation captures the necessary context to correlate stack traces and locate the original trigger.

Debugging cascading flaky tests requires a defense-in-depth approach using structured tracing and instrumentation. Correlating stack traces and test outputs isolates the original trigger instead of just addressing the symptom.

Yes, you start by enabling the instrumentation guidance provided to capture context and stack traces. Once instrumentation is in place, you reproduce the error and trace backward from the symptom to the origin.

No specific dependencies are required. The approach uses built-in instrumentation guidance to capture stack traces and intermediate states, allowing you to trace failures backward without external frameworks.

Avoid a defense-in-depth approach for simple, single-layer failures where the stack trace directly identifies the origin. It is designed for complex systems where errors propagate through multiple layers and require correlation.
