 The Console presents operator dashboards for scans, policies, VEX evidence, runtime posture, and admin workflows.
 
 ## Latest updates (2026-03-08)
+- Preserved canonical `Ops > Platform Setup` leaf URLs so `regions-environments`, `promotion-paths`, `workflows-gates`, and `gate-profiles` no longer rewrite into `Setup > Topology` on direct entry or quick-link navigation.
+- Added checked-feature verification for canonical platform-setup route preservation at `../../features/checked/web/platform-setup-canonical-route-preservation-ui.md`.
 - Shipped the `Mission Control`, `Security`, and `Ops > Operations` security-leaves cutover, including canonical surfacing for alerts, activity, unknowns, and notifications plus repaired `/analyze/unknowns*` and `/notify` ownership.
 - Added checked-feature verification for the security operations leaves cutover at `../../features/checked/web/security-operations-leaves-ui.md`.
 - Shipped the canonical `Setup > Topology` and `Setup > Trust & Signing` cutover, including repaired legacy trust bookmarks, fixed `Platform Setup` handoffs, and expanded topology shell exposure.
