Diagnostics and regression triage loop

This chart captures the expected maintainer response when lint/type/test/docs gates report regressions.

Why this matters

• Prevents symptom-fixing loops by requiring explicit root-cause confirmation.
• Keeps maintainers from skipping from one failing gate to broad speculative edits.
• Encourages reproducible regression tests before high-risk refactors.

Command strategy

• Start focused: single file diagnostics or targeted tests.
• Expand only after local root cause is stable.
• Finish with full quality gates for merge confidence.
