From 8c734fe230ebba7c49d9ea90ed6bec3013549f5e Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Wed, 24 Jun 2026 21:37:57 -0700 Subject: [PATCH] FN-6973: stabilize engine liveness tests Stabilize engine tests around executor liveness cleanup and scheduler handoff expectations. - Assert task-move cleanup clears active session registry entries for agent, step, and workflow-step sessions. - Reset active session registry module state between executor tests alongside executing task locks. - Relax brittle worktree and scheduler assertions to match current merge-base and handoff behavior.
