# Export raw ES evidence for one case time-window to NDJSON, then pseudonymize.

# Data lives in the LIVE cluster; this snapshots the docs behind a case so the
# corpus is portable / shareable (after pseudonymization).

# Setup (do NOT commit the password):
#   export ES_URL="https://your-es-host:9200"
#   export ES_USER="elastic"
#   export ES_PASS="<the elastic password>"     # from Kibana / your ES keystore
#   export BENCH_PSEUDO_SALT="<stable secret>"
