Arch Review Dashboard (removed)

The dashboard gave platform operators a cross-tenant view of the knowledge graph: new observations as they arrived, deviations from established patterns grouped by project, and a histogram of how confident the system was in its current graph state. None of that operator UI exists today.

What is still real: the underlying read path (src/lib/arch/query.ts) was not deleted - it is now consumed by the capability.architecture workflow node and the nightly synthesis job, not by an operator dashboard. See Arch Query Layer for the surface that replaced it, and the capability.architecture node for how a project-scoped agent session reaches the same knowledge graph today.

What was removed

• The admin page at /admin/arch/review and its client component
• GET /api/admin/arch/review/recent, /drift-summary, /confidence-histogram
• createArchReviewSdk() and the rest of src/lib/arch/review.ts
• The project-level /architecture page and the /nodes authoring surfaces (catalog, reviews, marketplace) that shared the same dead-flag cleanup
• The screen_architecture and screen_nodes feature flags and their nav entries

There is no tenant-scoped or operator-scoped replacement UI for cross-project drift/confidence review. If you need that visibility today, query graph_nodes and observations directly - see Knowledge Graph Store.
