- org-graph-unification-phase1-review-gate-design.md: implementable SDD for inserting a planner_reviewer stage (new org role, since _PRE_STATE/ _POST_STATE map org_node -> status 1:1 and can't reuse "validator" twice) between Planner and Coder. Folds in the P0 resume-artifact-assumption fix and a newly-found sibling KeyError in the fresh-run path. - graphlemon_architecture.md §10.2: records that §10.1's "方案 A" (reuse Claude Code's native Dynamic Workflow for Work Graph execution) was superseded -- the graph-orchestration layer already diverged (REQ-06 checkpoint/resume), and per today's decision the single-node execution layer is being migrated off it too, for controllability. - work-graph-node-execution-deblackbox-requirements.md: requirements+design for that migration -- replace the 3 remaining write_workflow_script/ execute_work_graph call sites with plan_work_graph()'s already-proven flat `claude --agent` + JSON-fence-extraction pattern. - Cross-referenced the two new docs from each other and from the existing P0/P2 todo docs they fold into or relate to.
