* docs(kms): correct the static backend's MinIO compatibility claim `StaticConfig` claimed the backend derives DEKs via "HMAC-SHA256 + AES-256-GCM, matching the MinIO builtin/static KMS wire format". Neither half holds: the configured key is used directly as the AES-256-GCM key with no derivation step, and wrapped DEKs are serialized as RustFS's own `DataKeyEnvelope` JSON. MinIO's KMS ciphertext uses a different shape, which `is_data_key_envelope` explicitly classifies as foreign (see the `minio_legacy` case in encryption/dek.rs). The claim as written tells a migrating operator that MinIO-written ciphertext will open here, which it will not. Restate what the backend actually does and point at rustfs/backlog#1638 for the real interop work. Also refresh the neighbouring ciphertext-format note in static_kms.rs, which still described a raw `ciphertext || nonce` layout that the JSON envelope replaced. * ci(minio-interop): fix the dead test selector and guard against empty runs The job selected its tests with `-p rustfs-ecstore -E 'binary(minio_generated_read_test)'`. #5435 moved those reader tests from crates/ecstore/tests/minio_generated_read_test.rs into the `rustfs` crate as a `#[cfg(test)] mod`, which removed that test binary; the selector has selected zero interop tests since. Point it at the tests where they now live, verified locally: cargo nextest list --run-ignored all -p rustfs --features rio-v2 \ -E 'test(minio_generated_read_test::)' # 4 tests, was 0 Add a guard step in front of the run. The old `binary(...)` form happened to fail loudly once its binary disappeared, but the name-based form that replaces it is a valid filterset even when it matches nothing, so a later rename would silently reduce this job to a pass that asserts nothing. The guard counts the selection and fails with an explicit reason; the count comes from `filter-match.status`, since the JSON's top-level `test-count` is the package total and ignores `-E`. `--no-tests=fail` on the run step covers the same case if the guard is ever dropped. Also record in the header what this job does and does not prove: MinIO wrapped-DEK envelopes are still rejected by both envelope parsers, and that work is tracked in rustfs/backlog#1638.
