Runs the Four-Layer Minimal Repro ladder to reproduce PR blockers quickly with evidence-backed classification.
Four-layer minimal repro ladder for PR-blocker regressions related to BYOK (Bring Your Own Key) and provider settings, from unit tests through browser UI verification.
Generates complete layered testing strategy (L1-L4 pyramid), plans, architecture, scenarios, code templates, and CI/CD configs for Backend+APP, Backend+WEB, or Backend+APP+Embedded projects.
Systematic debugging techniques for unclear root causes. Uses test bombs (hypothesis elimination) and layered tests (pipeline stage isolation) to narrow down failures.
