-# RustFS Fault-Tolerance (degradation) Test
-#
-# Scenario suite for the 2026-09 degradation report: verifies read/write
-# behavior under drive and node loss against the erasure-coding contract and
-# snapshots health-endpoint responses at every tier.
-#
-#   A  single-node 4 drives (SNMD): hide 1/2/3 drives, restore
-#   B  multi-node 4x1 (one drive per node): stop 1/2/3 nodes, restore
-#   C  multi-node 4x4 (16 drives, EC:4): stop 1 node (read-quorum boundary),
-#      stop 2 nodes, restore
-#   C2 multi-node 4x4 with EC:8: 2 nodes down puts 8 drives online -- reads
-#      satisfy the EC read quorum while the lock majority is broken (the
-#      reported divergence window: reads 503 with lock_quorum_unavailable)
-#
-# Expectations come from product source (default_parity_count, erasure set
-# sizing). By default a "reads refused although the read quorum is met"
-# observation is reported as known-divergence without failing the suite; the
-# strict input turns those into failures once the product behavior changes.
