# Cross-day lesson — Parallel Machining, 2026-04-30 _Generated by `gpt-oss:20b` in 5.5s. Based on 3 events + 1 mid-day checkpoints._ ** Before any shift, verify that all tools are calibrated and that the pool assignment is set—an unset pool causes immediate failure. For emergency tasks, perform a quick drift check and recalibrate tools on the spot to mitigate drift risk. Apply the same pre‑check routine to baseline and recurring tasks to avoid cascading failures. Keep a ready‑to‑run calibration script in the agent’s routine for rapid deployment.
