# D4 smoke — proves the Day 4 acceptance gate end-to-end.
#
# Validates:
#   - POST /ingest?name=workers with a small CSV → 200 + manifest
#   - mc shows the parquet under datasets/workers/data.parquet
#   - catalogd /catalog/manifest/workers returns matching row_count
#   - Schema fingerprint is deterministic on re-ingest of identical CSV
#   - Re-ingest same CSV → existing=true (idempotent)
#   - Re-ingest CSV with a different schema → 409 Conflict
#   - ADR-010: mixed numeric/N-A column inferred as string
#
# Requires storaged + catalogd both up (they're launched by this
# script). MinIO must already be running on :9000 with bucket
# lakehouse-go-primary.
#
# Usage: ./scripts/d4_smoke.sh
