Real, computed, shared by both views: reorder point, days of supply, order-up-to level, order quantity locked at trigger day, expiration countdown, classification-adjusted safety stock, demand-adjusted usage, and risk score. One function, `computeState()`, powers the list ranking and the timeline — there is no second copy of this math anywhere in the file.
Simulated: the six Tier II systemic vectors, shown only in the timeline view. In production these come from real order and usage history.
Reused, not re-derived for this domain: the 258/300 PROHIBIT composite threshold and Lucid Drill's three-phase structure, carried over from the original ROT12 architecture.
Not built: no connection to any real system. Every input here is manual entry, standing in for what would come from your ERP, purchasing, vendor feed, or surgery schedule in production.
