hotfix

Fixes an observed defect with reproducible evidence in one call: writes a short trace doc before touching code, implements the fix, and backs it with a regression test written before the fix. Production incidents are the motivating case, not a gate. When blocked, it halts by name and saves the doc for a later call to resume. Use when a defect has concrete evidence and you need the fix with its paper trail now — planned small tasks belong to quick, spec'd features to implement.
