Implement external proposal approval as independent of estimate timing; material proposal changes invalidate stale approval, while estimate-only revisions preserve it until exact decision projection. Do not project a separate proposal-feasibility Reviewer assignment. After the minimum planning percentage, select acting only when approved, estimated graph work is ready; otherwise continue or resume planning. Support multiple proposals concurrently, including same-project proposals. Carry unfinished graph work into later workdays; Reporter closes the current workday based on settled attempts, not full proposal completion. Remove estimate-derived minimum admission floors. Package-owned regression scenes: approval-before/after estimates, no approval denial, 15 proposals, phase transitions, short workday carry-forward, early completion. Parent treeseed-ai/platform#520.
