Prevent trigger recursion when rollup updates cascade across five related objects

• Map cross-object trigger chain in architecture diagram before coding • Static recursion guard keyed by object + operation not global boolean • Consolidate rollups into single after-trigger pass per object • Use Platform Event for downstream enrichment instead of synchronous cascade • Integration bypass via hierarchy custom setting for known bulk paths • Test recursion with 200-record bulk insert simulating production order volume • Consider declarative roll-up summary or DLRS for simple sums reducing trigger coupling
