 | Full-canvas workspace | Navigation/content and list/detail canvases that own pane geometry and scrolling | Navigation and split variants, primary-pane width, pane-owned or contained scrolling, responsive stacking or navigation collapse, pane labels, and contextual-help identity are centralized without encoding domain navigation | `WorkspaceLayout.tsx`, `workspace-layout.test.tsx`, Core Settings, Access administration, Docs, Organizations, Campaign, Templates, Approvals, and `check-shared-webui-layouts.py`; the raw-workspace exception baseline is empty |
 | Full-height module frame | Outer module landmark and viewport/container sizing | `WorkspaceFrame` centralizes surface, overflow, box sizing, accessible naming, help identity, and application-viewport height so modules do not copy the `100vh - shell` frame | `WorkspaceFrame.tsx`, `layout-primitives.test.tsx`, Dataflow, Workflow, Datasources, Distribution Lists, Notifications, Tasks, Scheduling, Forms, Portal, Projects, Records, and Reporting |
 | Responsive action toolbar | Domain-neutral action and filter grouping for pages, workspaces, editors, and overlays | Density, surface, grouping, flexible space, accessible naming, toolbar help identity, and responsive wrapping are centralized while modules retain action wording, authority, and consequence | `ActionToolbar.tsx`, `layout-primitives.test.tsx`, WYSIWYG, Calendar, Files, Forms, Templates, and the product-wide primitive check |
-| Semantic page archetypes and action bar | Overview, collection, detail, editor, and workspace intent declared independently from frame geometry and composed over the responsive toolbar | Refreshable pages require leading Reload; editor persistence owns clean/dirty/saving feedback, guarded Discard and far-right Save; destructive actions occupy an explicit separated slot; read-only pages do not invent Save | `PageLayout.tsx`, `PageActionBar.tsx`, `PAGE_LAYOUT_USAGE_GUIDELINES.md`, component and browser conformance, every headed product page, and `check-shared-webui-layouts.py` |
+| Semantic page and pane action bars | Overview, collection, detail, editor, and workspace intent declared independently from frame geometry; full-canvas panes add workspace/collection/detail/editor scope | Core renders leading Reload from a guarded descriptor; editor persistence owns clean, dirty, invalid, saving, failed, and conflict feedback plus guarded Discard and far-right Save; destructive actions occupy an explicit named boundary; read-only surfaces do not invent Save | `PageActionBar.tsx`, `WorkspaceActionBar.tsx`, `PAGE_LAYOUT_USAGE_GUIDELINES.md`, component and browser conformance, every headed page and full-canvas workspace, and the discovery-based `check-shared-webui-layouts.py` |
 | Catalogue and state composition | Search/filter bars, selectable navigation lists, count badges, and empty/blocked/error panels | Width, surface, wrap, selection geometry, title/description truncation, numeric emphasis, state sizing, tone and action placement are centralized; modules retain query behavior, object state and consequences | `FilterBar.tsx`, `SelectionList.tsx`, `CountBadge.tsx`, `StatePanel.tsx`, `layout-primitives.test.tsx`, and list/detail modules across Cases, Committee, Dataflow, Forms, Notifications, Portal, Postbox, Projects, Records, Reporting, Tasks, Templates, and Workflow |
 | Content and form grids | Equal-column content, field, and native-form geometry | Explicit 1–4 columns, standard gaps, item spans, alignment, and named narrow/workspace/standard/wide collapse points replace generic and module-prefixed copies; unequal domain tracks remain local | `ContentGrid.tsx`, `layout-primitives.test.tsx`, Core dashboard/settings/mail, Calendar dialogs, Forms editor, Datasources, Postbox, Campaign, administration surfaces, and the product-wide primitive check |
 | Content sections | Repeated editor/detail section surfaces | Border, surface, compact/default density, stacked flow and block rhythm are centralized without encoding section contents | `ContentSection.tsx`, `layout-primitives.test.tsx`, Datasources, Distribution Lists, Templates, Dataflow, and Workflow |
 | Form sections | Reusable heading/description/action/content grouping inside forms | Plain, separated, and panel variants centralize hierarchy and narrow action placement without moving validation, permissions, values, or domain wording into Core | `FormSection.tsx`, `layout-primitives.test.tsx`, Addresses contact editing, and Quick Access preferences |
-| Metric groups | Reusable responsive grouping around metric cards | Fixed one-to-five and auto-fit columns, minimum card widths, density, block/inset/zero spacing, and named collapse points replace the product-wide `metric-grid` class and cross-module dashboard overrides | `MetricGrid.tsx`, `MetricCard.tsx`, `layout-primitives.test.tsx`, Core and Dashboard summaries, administration, Campaign, Ops, Files, Search, and dashboard widgets |
+| Metric groups and drill-downs | Reusable responsive grouping around metric cards with an explicit optional detail affordance | Fixed one-to-five and auto-fit columns, minimum card widths, density, block/inset/zero spacing, and named collapse points replace the product-wide `metric-grid` class and cross-module dashboard overrides; typed link or in-page drill-downs name their destination while summary-only, non-enumerable, derived, or privacy-suppressed values remain inert | `MetricGrid.tsx`, `MetricCard.tsx`, `metric-card.test.tsx`, `layout-primitives.test.tsx`, Core and Dashboard summaries, administration, Campaign, Ops, Files, Search, and dashboard widgets |
 | Description lists | Semantic property and fact presentation | Stacked and inline variants, one-to-five list columns, density, term width, wrapping, and responsive collapse replace both `admin-details-grid` and `detail-list`; `DescriptionItem` preserves native `dt`/`dd` anatomy | `DescriptionList.tsx`, `layout-primitives.test.tsx`, Access and Tenancy administration, Audit, Policy, Campaign reports/imports, Docs, Settings, Ops, and Reporting |
 | Dialog anatomy | Shared outer dialog plus composable body and footer regions | Size and administration variants, body padding, descriptions, notices, fixed action wrapping, native form flow, and section grouping are centralized; focus trapping and stack lifecycle remain unchanged | `Dialog.tsx`, `DialogAnatomy.tsx`, `dialog-focus.test.tsx`, `layout-primitives.test.tsx`, Addresses, Calendar, Records, Datasources, Distribution Lists, Files, and Templates |
 | Definition-editor visuals | Reusable graph palette, canvas chrome, node icon/port geometry, empty overlay and floating activity state | Core owns visual and responsive anatomy while node/edge types, validation, execution, provenance and workflow semantics remain in Dataflow or Workflow | `DefinitionPalette.tsx`, `DefinitionNodeIcon.tsx`, `FloatingStatus.tsx`, shared definition styles, Dataflow and Workflow structure/build checks |
