Record the decisions,\nopen questions, and exact next action, then change this package's session mode from planning to\nready when a notebook exists. This explicit invocation authorizes leaving planning, not approval\nof every proposed item. Promote only work the owner approved. Begin implementation only if the\nowner requested it; otherwise return the next step. Do not call the full plugin's plan-exit runtime\nor remove its markers. If there is no saved plan, say so and use the current conversation's plan.\n"
