# Builds a self-contained EF Core migration bundle for VigilCareClinicalAPI.
# CD (Phase 36 Step 12) runs the same command; this script is for local dry-runs
# and for operators who apply schema changes before rolling the API image.
#
# Usage (from repo root or anywhere):
#   ./scripts/build-api-migration-bundle.sh
#   RID=win-x64 ./scripts/build-api-migration-bundle.sh   # local Windows test
#
# Apply against a database (DDL-privileged connection string):
#   ./artifacts/migrate-api --connection "$PG_CONNECTION_DDL"
#
# Zero-downtime discipline: every migration must be backwards-compatible with
# the previously deployed API image (expand-then-contract). The bundle runs
# while old containers are still serving traffic.
