# MinIO on-disk interop: prove RustFS reads MinIO-written erasure-coded SSE
# objects with byte-identical data and correct logical size.
#
# This is NOT a PR gate. The fixtures are real MinIO backend trees generated on
# the fly (they are gitignored, never committed), so the job regenerates them
# each run with Docker and then runs the `#[ignore]` reader tests in
# crates/ecstore/tests/minio_generated_read_test.rs.
#
# Runner: GitHub-hosted `ubuntu-latest`. It reliably ships Docker + Python,
# unlike the self-hosted fleet, whose pods drift in Docker/pip availability
# (see the infra note in e2e-s3tests.yml). Nightly + manual only.
