         Graph-owned execution may complete explicitly independent steps out of index order, but unannotated task plans are sequential by default. FN-7228 showed Testing & Verification starting while Preflight/implementation were still active because step-session planning treated missing dependencies as independent. Keep TaskStore projection consistent with the graph scheduler: absent dependsOn means previous-step dependency; explicit dependsOn: [] means independent.
+
+        FNXC:WorkflowStepControl 2026-06-30-07:45:
+        FN-7260 showed the same ordering invariant can be broken earlier by agent-visible progress updates: a stale resume prompt told the executor to start Step 3 while Step 0 was still in progress, and TaskStore accepted the out-of-order `in-progress` write. Apply the predecessor/dependency gate to step start as well as step completion so the card, task detail, and executor prompt cannot advertise later sequential work before earlier steps finish.
