From 3dff1bd1fd788254a284319f4761ea7e5985cb5a Mon Sep 17 00:00:00 2001 From: lukemartinlogan Date: Fri, 13 Feb 2026 02:51:57 +0000 Subject: [PATCH 1/6] Add crash-restart persistence feature and integration test Implement the full restart pipeline: RestartContainersTask in admin module, FlushMetadata/FlushData tasks in CTE core, compose restart config saving, and a multi-process integration test that exercises the workflow (compose with restart=true, put blobs, flush, stop runtime, restart, RestartContainers, verify pool recreation). Fix compose restart config format to wrap pool YAML in compose: section for proper parsing by RestartContainers.
