What problem does it solve?
Provides a disciplined, repeatable methodology for diagnosing software that behaves differently than expected by tracing execution, recording findings, and isolating root causes to prevent regressions.
Core Features & Use Cases
- Blackbox callstack tracing: Follow the callstack step-by-step across files and services while writing exact filename:line observations to a persistent trace log.
- Hypothesis-driven exploration: Start with a top-3 heuristic check then move to exhaustive branch exploration, ensuring no branch remains unexamined.
- Red-Green verification cycle: Reproduce the issue with a failing test, implement a focused fix, and confirm the fix plus regression safety.
- Use Case: Use when a production or test failure is non-obvious—record the trace, form single hypotheses per iteration, and converge to a reliable fix with instrumentation and layered guards.
Quick Start
Start at the failing entry point, follow the callstack one step at a time into each file or service, and record each filename:line and conditional outcome into the trace log while iterating on single hypotheses and writing a reproduce-first test.
