From 0d7f907e9fd20dca9e9e1d4b5021e87c947aee27 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Fri, 4 Sep 2026 13:51:06 +0000 Subject: [PATCH] test(e2e): harden 4-node distributed Actions coverage Classify localhost DistErasure pool-meta write fences instead of failing the suite when decommission/rebalance POST is blocked, use the proven 2x2 volume-proxy topology, and add peer-kill GET plus bucket recreate cases.
