Split the original Phase 5 (lead-written plan) into Phase 5 (insight
distillation) and Phase 6 (mandatory plan agent handoff via
task(subagent_type="plan")). The lead now produces a structured insight
bundle and dispatches it to the dedicated planner — the planner owns
sequencing, parallelization, and verification gates.
This mirrors the ultrawork plan-agent contract: adversarial distillation
extracts only defensible insights, the planner formalizes them into an
executable plan. Skipping the handoff turns hyperplan back into vanilla
orchestration.
- Update workflow phase count 6 → 7
- Anti-patterns: forbid lead-written plans, forbid skipping the dispatch,
forbid pre-writing tasks before dispatch, forbid using team_send_message
to ship the bundle to the plan agent
- Notes: synchronous dispatch (run_in_background: false), planner has no
team mailbox access (everything must be in the bundle)
