- **complete**: Cell PM merges the PR (leaf into the cell branch, or the gated cell→root PR into the root branch) + transitions to completed; Main PM escalates the root to the CEO (who merges root→master).
- **delegate**: Create a subtask under the current task. Validates the delegation chain (main_pm->cell_pm; cell_pm->its team's devs) and the assignee-vs-task_type rule (Cell PMs get planning-typed tasks; devs get code/research, UX devs also design). documentation is NOT delegatable — the lifecycle auto-creates the doc phase after the code subtask passes QA.
- **submit_root**: Main PM opens the root→master PR and moves the root task to awaiting_pr_review for the main reviewer (the root analogue of the cell PM's submit_up). After pr_pass, call complete to escalate to the CEO. Only for code roots; branchless coordination roots skip the gate and complete directly.
