Follow-up:

• The broader discuss mode proposed in the issue refinement comment — multiple outcome types (implement, do-not-implement, needs-human, split) posted as a signed consensus comment — would generalize the planning infrastructure already laid down here.

This was mentioned in an approved review as future work and did not block merge readiness.
