One Epic, 4 linked slices — keeps end-to-end traceability without a mega-PR that breaks layering/CI. Copy this template for each fund flow; slice 1 blocks 2-3, 4 is the integration gate.
Facilities move money three ways from the same ledger. These share JournalEntry + TransactionConcurrence + permission model, so they belong to one epic but ship as slices for parallel review.
