From 058416e99aa9328c891bc14ff29f86eef3d4d49f Mon Sep 17 00:00:00 2001 From: jedarden Date: Sun, 24 May 2026 16:57:55 -0400 Subject: [PATCH] =?UTF-8?q?feat(ilm):=20add=20acceptance=20tests=20for=20I?= =?UTF-8?q?LM=20rollover=20(plan=20=C2=A713.17)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive acceptance tests for ILM rollover functionality: - max_docs trigger fires: new index created; write alias flipped; read alias updated - keep_indexes retention: oldest indexes deleted per policy - safety_lock blocks deletion of young indexes with clear logging - multi-target alias rejects operator PUT attempts All 14 ILM tests pass, including 6 new acceptance tests.
