+Scope is the canonical Task record and reader-page host, while Architecture remains semantic owner of task derivation, dependencies, and readiness. Kanban and Delivery own task flow and execution evidence. Synchronize those dimensions into the Scope reader without duplicating ownership or inventing transitions.

During display-ID migration, preserve historic canonical identities, aliases, evidence, and append-only hashes; do not rewrite historical events or hashes solely to replace a legacy display name.
 
 Approval is a gate, not a delivery status. Preserve `Approved for Solution`, implementation approval, conditions, and decision evidence in dedicated fields and append-only histories; do not overload the item's delivery status with approval language.

 ## Verification Checklist
 
 - [ ] Only the six same-project channels were inspected.
 - [ ] Scope appears immediately before Architecture with its own sidebar.
-- [ ] Sidebar order is Overview, Roadmap, Ideas with child pages, Questions with child pages, then Epics with nested Features.
+- [ ] Sidebar order is Overview, Roadmap, Ideas with child pages, Questions with child pages, then the exact Epics → Epic → Features → Feature → Tasks hierarchy.
 - [ ] Ways of Working starts with a separate Scope page explaining the ticket hierarchy and governed statuses.
 - [ ] Ideas and Questions use table-free parent/child pages; no Product Register page exists.
 - [ ] Roadmap distinguishes verified current state from predicted plans.
-- [ ] Epics and Features use stable project-scoped IDs and valid parent-child links.
-- [ ] Every Epic links child Features; every Feature links authoritative tasks when present.
+- [ ] Epics, Features, and Tasks use stable project-scoped IDs and valid parent-child links; Task display IDs use `<UPPERCASE_PROJECT_CODE>-TS-<NUMBER>`.
+- [ ] Every Epic has an explicit Features group; every Feature has an explicit Tasks group; every Task has a separate canonical Scope reader page.
+- [ ] Scope hosts Task readers, Architecture owns derivation/dependencies/readiness, and Kanban/Delivery own flow.
+- [ ] Display-ID migration preserves historic canonical identities, evidence, aliases, and append-only hashes.
 - [ ] Ideas preserve provenance when promoted.
 - [ ] Every item uses the governed status vocabulary for its type; approval, blocking, and release evidence remain separate fields.
 - [ ] Idea, Epic, and Feature roll-ups use complete validated required-child sets with no ancestor/descendant double counting.
