+-- flag_group_code='AYAM' and deactivated the global rule. That left TELUR /
+-- TELUR_GRADE with no matching block, so resolveOverConsume() fell back to the
+-- default rule 'fifo_v2_default_allow' (allow_overconsume=TRUE) and egg
+-- Delivery Orders could over-sell silently into marketing_delivery_products.pending_qty.
+--
+-- These rules make resolveOverConsume('TELUR'|'TELUR_GRADE','MARKETING_OUT') = FALSE,
+-- so an egg DO that exceeds available stock is REJECTED (ErrInsufficientStock)
+-- instead of being recorded as pending. Scope is "Telur saja" — AYAM and
+-- transfer behaviour are intentionally left unchanged.
+--
+-- NOTE: run the total_used reconciliation (cmd/reconcile-fifo-total-used) BEFORE
+-- applying this in production. Enabling the block while phantom total_used still
+-- inflates consumption would reject otherwise-valid egg orders.
