Schedule โ plan of record
ScheduleRevision / ScheduleInterval. One board, configured per operation.
Cycle-time updates and fork-truck observations are deviations against the plan in force, not edits to it. A published plan that silently becomes whatever happened makes attainment-against-plan meaningless โ the same failure as a standard refreshed to the last actual. No deviation grain exists yet, so this board is read-only by construction and there is no control here to suggest otherwise.
Preassembly & staging gains under H-1: material readiness ยท fork-truck deviation ยท staged-for run
This is the published plan. Production Schedule is a finite-scheduling simulation over synthetic batch history and reads no database. The work queue is the same plan at real-time grain (D4). Two subjects one word apart โ flagged under R1, not resolved here.
