What problem does it solve? Changes to live production-run state logic (auto-track counters, dough supply, pause/resume, SSE sync) can silently corrupt timers and counters, causing wrong case counts, frozen dough timers, or stale SSE echoes overwriting operator edits. This Skill provides a systematic verification checklist to catch those accuracy regressions before they ship. ## Core Features & Use Cases - Seven Accuracy Categories: Covers clock isolation, case/skid auto-track counters, dough tray/batch counters, pause/resume consistency, Frontline/Sauce cadence, SSE counter drift, and the press-done model. - Cross-Run Safety Checklist: Verifies the three lines of defense (lastFormRunIdRef guard, empty-over-populated guard, deep-equality reset guard) that prevent form resets from clobbering another run's data. - Reset Reference Table: Documents exactly which bookkeeping refs reset in resetBookkeeping(), on run resume, and via fireAutoTrackNow(), so ref lifecycle changes stay consistent. - Use Case: After editing useAutoTrack.ts to change tray depletion cadence, walk the dough-supply category to confirm remainder carry, seeding refs, and the pressDone gate still behave correctly. ## Quick Start Ask the assistant to run the state accuracy check on your recent changes to LiveRunContext.tsx or useAutoTrack.ts before committing them.
