To find the root cause of an ambiguous bug, you need an evidence-based investigation process that traces causal mechanisms through implementation, configuration, and measurement lanes before crystallizing requirements. This approach prevents blind guessing by validating the actual source of the failure.

The best way to investigate uncertain system failures across existing codebases is running parallel trace lanes that split causal investigation into implementation, configuration, and assumption mismatch categories. This targeted evidence gathering handles brownfield environments by exploring existing code directly.

Evidence-based debugging transitions into actionable specifications by injecting trace conclusions, system context, and unresolved questions directly into a targeted interview. This structured process generates a spec-ready document with a dedicated trace findings section and an execution bridge for planning.

Yes, you can use structured trace analysis for new feature exploration when the root cause or requirements are uncertain. The process treats new work as greenfield exploration, applying the same evidence-based investigation to crystallize accurate specifications before development planning begins.

You should avoid blind guessing and use a pipeline orchestration approach for root cause analysis whenever the problem is ambiguous and evidence is lacking. Running a structured two-stage trace and interview pipeline ensures confidence gating is applied before finalizing any requirements or spec artifacts.
