User-facing capability

Problem or need

A tenant-rooted Workplace needs a useful landing page that helps users discover their accessible agentic spaces and resume recent work without flattening all Workspace-owned content into one undifferentiated catalogue.

Expected outcome

The Tenant Workplace home presents accessible Workspace spaces, recent/resumable cross-space activity, and optional promoted Entries while preserving each item's owning Workspace and execution context.

Proposed solution

Build a Tenant-level read model that aggregates only user-facing summaries from authorized Workspaces. Keep authoritative conversations, tasks, Entries, and execution state in their owning Workspace and deep-link back to that context.

Scope

• Accessible space cards/list/search.
• Recent/resumable conversations/interactions across authorized spaces.
• Relevant user task/activity summaries where supported.
• Promoted Entries allowed by Define shared Entry exposure across Workplace and Console surfaces #315 exposure policy.
• Owning-space labels and deep links.
• Pagination/bounds and deterministic ordering.
• Empty/loading/partial-failure states.
• Localization, accessibility, responsive UX, tests.

Out of scope

• Moving authoritative activity to Tenant scope.
• Tenant-wide Management resource search.
• Arbitrary cross-Workspace content aggregation outside authorized Workplace projections.

Dependencies

Parent: #338.
Depends on #340 and #315. Activity aggregation may reuse existing Work/Interaction projections.

Deployment impact

None

Acceptance criteria

• Tenant home lists only spaces accessible to the current principal.
• Recent activity can span authorized Workspaces while retaining the owning Workspace on every item.
• Resuming an item navigates back into its authoritative Workspace context.
• Promoted Entries appear only when their exposure policy allows Tenant-home presentation.
• No sibling Workspace resource visibility is granted by the aggregation layer.
• Aggregation is bounded, paginated where needed, and handles partial failures safely.
• Browser tests cover multiple spaces, mixed activity, promotion, and authorization isolation.
