"""Pro-graph step summarizer node (M2: visual-transition lens dispatch).
Per the history-module redesign §5 (single step-level lens, confirmed
2026-08-31) this node no longer generates a per-step text capsule with its own
LLM call. It dispatches the step to the shared
:class:`~artemis.memory.step_memory.StepMemoryService` visual-transition lens
(``ctx.step_memory``): pre/post screenshots are pulled from the DataEngine by
step id, the red action-overlay and the ``flash_summarizer.md`` neutral-wording
contract apply unchanged, and the result lands as a versioned
``source="visual_transition"`` summary write (M0 semantics).
The auxiliary agents' compiled view (``build_plan_and_history``) is untouched:
a step whose summary is not ready yet falls back to detailed rendering
(``task_tree.py`` semantics), so the transition is safe. The intent/strategy
capsule moves up to the chunk-level ``StepCapsuleLens`` in M3.
