# Cross-day lesson — Riverfront Steel, 2026-04-21 _Generated by `gpt-oss:20b` in 5.6s. Based on 5 events + 2 mid-day checkpoints._ ** When expanding a shift that requires multiple forklift operators, pull a fresh subset of operators from the pool that excludes those already assigned to the Toledo shift; maintain a temporary exclusion list to avoid duplicate assignments. For any misplacement or re‑assignment, lock the worker’s schedule before assigning a new shift to prevent double‑booking—especially for high‑demand staff like Ryan Hughes. Verify the pool size and current turns before processing an emergency request; if the pool is insufficient, trigger a contingency plan. Keep a real‑time log of all assignments to catch overlaps early.
