ILM on SSE-KMS buckets while per-key SSE authorization is enforced (backlog#1582). +//! +//! Per-key KMS authorization (`RUSTFS_KMS_ENFORCE_SSE_KEY_POLICY=true`) scopes the +//! SSE-KMS data path to the requesting principal's `kms:GenerateDataKey` / +//! `kms:Decrypt` grants. Internal callers — the lifecycle scanner's expiry deletes +//! and the tier transition worker's reads — carry no request principal, and +//! `authorize_sse_kms_key` (rustfs/src/storage/sse.rs) exempts a `None` principal +//! so background maintenance keeps working on encrypted buckets. +//! +//! These tests pin that exemption end to end. If enforcement ever starts applying +//! to the scanner's internal operations, expiry stops happening on SSE-KMS buckets +//! and [`ilm_expiration_on_sse_kms_bucket_under_enforcement`] times out; if it +//! starts applying to the transition worker or the read-through path, +//!
