> {{tools/releasing/deploy_staging_jars.sh}} line 23 is {{MVN=${MVN:-mvn}}} and

> {{tools/azure-pipelines/build-nightly-dist.yml}} exports {{CUSTOM_OPTIONS}}

> The enforcer has required {{[3.9.16]}} since FLINK-40459 on 2026-08-28, but
> the job died earlier on the stale {{free_disk_space.sh}} path until
> FLINK-40654, so build 79074 is the first run to reach it.
> {{tools/ci/maven-utils.sh}} already resolves
> {{MAVEN_WRAPPER="${CI_DIR}/../../mvnw"}}, and {{build-nightly-dist.yml}} is
> the only caller of the script.
