 // Stock macOS ships bash 3.2, where expanding an EMPTY array under `set -u`
 // is a fatal "unbound variable" — the `:-` guard on the provenance CSV is what
 // keeps the keyless `dev-fresh.sh` launch alive there. Newer bash never fails
 // this way, so the idiom itself is asserted textually and the block's behavior
 // is exercised for both the keyless and the populated case.
