From framework review (docs/framework_review.md), P1-5. ZAP_MOMENT = date('Y-m-d-H_i_s') has second resolution. Two submissions in the same second collide on mkdir — suppressed with @, returns null folder, silently breaks all downstream operations. Fix: append random suffix to folder name, drop @, add recursive flag.
