# OMNL — Build omnl_transaction_package_snapshot.json for Volume A Section 2 (GET offices + glaccounts).
# Enriches each office with registry LEI / entity name from OMNL_ENTITY_MASTER_DATA.json (offices model;
# Fineract does not store LEI on the office resource).
# Usage: OUT_DIR=. bash scripts/omnl/omnl-transaction-package-snapshot.sh
# Writes: $OUT_DIR/omnl_transaction_package_snapshot.json (default REPO_ROOT)
#   ENTITY_DATA=path/to/OMNL_ENTITY_MASTER_DATA.json (optional; default under docs/.../mifos-omnl-central-bank/)
