Scope

Use one governed hierarchy: Idea → Epic → Feature → Task. Scope owns stable product identity and canonical reader pages; Architecture owns task derivation, dependencies, and readiness; Kanban owns Focus admission; Delivery owns execution evidence; Releases owns release evidence.

Delivery status

Product items use IN_BACKLOG, IN_DESIGN, IN_DELIVERY, TO_BE_RELEASED, DONE, or CANCELLED. Tasks use IN_BACKLOG, IN_PROGRESS, TO_BE_RELEASED, DONE, or CANCELLED. BLOCKED is a separate flag with a reason and durable evidence. Approval is a gate, never a delivery status.

Exact and roll-up authority

Task transitions and direct no-child decisions are EXACT. Epic and Feature states calculated from complete required-child sets are DERIVED. A parent cannot appear earlier than active required work, and it cannot become TO_BE_RELEASED or DONE while a required child remains earlier. CANCELLED is an authorized decision and never counts as done.

Dependencies, gates, and evidence

Record canonical dependency IDs, owner, blocker reason, approval conditions, actor, UTC transition date, previous and target state, and a durable source link. Scope approval, implementation approval, Focus admission, and release approval are separate gates. Silence, CI success, a merge, or documentation activity does not satisfy a gate or advance delivery status by itself.
