systematic-debugging

To find the root cause of flaky tests and regressions, capture concrete evidence, trace the failure backward, compare against known-good patterns, and validate hypotheses before implementing guarded fixes.

The best way to debug stubborn failures is using a phase-driven workflow that captures concrete evidence, performs backward tracing, tests hypotheses, and implements fixes with guardrails to prevent architectural drift.

To start systematic debugging, create an initial task list structured by phases and begin tracing evidence immediately to turn observed symptoms into traceable data points.

Yes, you can use systematic debugging for post-mortem investigations across code and environments, as it supports documentation and escalation to prevent architectural drift during root-cause tracing.

You should use defense-in-depth validation when fixing code regressions to ensure root causes are fully verified and guarded, preventing superficial patches that leave underlying issues unresolved.
