 ## Implemented And Enforced
 
 | Contract | Adoption evidence | Ownership now enforced |
 | --- | ---: | --- |
-| `ActionToolbar` and groups | 39 source files | Raw module-prefixed toolbar elements and local toolbar component definitions are rejected. |
-| `ContentGrid` | 15 source files | Former `dashboard-grid` and `settings-grid` wrappers are rejected. |
-| `FormGrid` and `FormLayout` | 53 source files | Former `form-grid` and `admin-form-grid` wrappers are rejected; equal-column dialog and editor grids were migrated even when they had module-prefixed names. |
-| `FormSection` | 2 representative source files | The reusable section API, variants, responsive action placement, and heading anatomy are Core-owned; broader adoption is incremental. |
-| `DialogActions` | Every Core `Dialog` footer | Footer wrapping and alignment are no longer repeated by consumers. |
-| `DialogForm` | 6 source files | Raw `*-dialog-form` form wrappers are rejected. |
-| `DialogSection` | 6 source files | Repeated dialog field/content grouping is available as a shared primitive. |
-| `MetricGrid` | 29 uses in 25 source files | The former `metric-grid` class and module-specific column overrides were removed. Core now owns 1–5/auto-fit columns, minimum width, density, block/inset/zero spacing, and collapse. |
-| `DescriptionList` and `DescriptionItem` | 51 lists in 28 source files; item composition in 11 files | The former `admin-details-grid` and `detail-list` classes were removed. Core now owns stacked and inline property layouts, density, term width, wrapping, and collapse while preserving native `dl`/`dt`/`dd` semantics. |
-| Standard dialog sizing | 9 consumers and 6 duplicated width rules removed | Confirmations and compatible Calendar, credential, Campaign, Files, and Voting dialogs use the Core small/large/wide scale. The 61 remaining specialized selectors across 22 CSS files are registered and decrease-only. |
+| `ActionToolbar` and groups | 50 source files | Raw module-prefixed toolbar elements and local toolbar definitions are rejected. Distribution, wrapping, density, grouping and panel/section surfaces are Core-owned. |
+| `PageLayout` / `WorkspaceLayout` / `WorkspaceFrame` | 25 / 16 / 17 source files | Headed page anatomy, full-height viewport frames and navigation/list-detail panes no longer repeat inset, heading, notices, loading, shell height, surface, overflow or pane geometry. The raw page-frame and raw workspace exception baselines are both empty. |
+| `FilterBar` | 14 source files | Catalogue and pane search/filter rows share width, surface, layout and wrapping. |
+| `SelectionList` family | 19 source files | Resource navigation shares selection, title/description, leading-icon and truncation anatomy. |
+| `StatePanel` | 25 source files | Whole-surface, compact and fill empty/blocked/error states replace module-local state shells. |
+| `CountBadge` | 8 source files | Notification, folder, search, postbox and graph counts use one compact badge contract. |
+| `ContentSection` | 5 source files | Repeated bordered/subtle editor sections and compact provenance panels share surface, density, flow and rhythm. |
+| `ContentGrid` | 22 source files | Equal-column content geometry and former dashboard/settings/assignment copies are Core-owned. |
+| `FormGrid` and `FormLayout` | 53 source files | Former generic/admin grids and equal-column dialog/editor copies use named collapse points and native form semantics. |
+| `MetricGrid` / `MetricCard` | 31 / 33 source files | Module-local metric helpers, grids and card visual definitions were removed. |
+| `DescriptionList` and `DescriptionItem` | 28 source files | Former generic property grids use semantic `dl`/`dt`/`dd` composition with central density and collapse. |
+| `DefinitionPalette`, node/canvas visuals and `FloatingStatus` | 2 Dataflow/Workflow consumers each | The copied graph palette, canvas controls, minimap, node icon/port, empty overlay and activity overlay definitions are Core-owned; graph semantics remain local. |
+| `DialogActions`, `DialogForm`, `DialogSection` | every Core footer / 6 / 6 source files | Footer action flow, native dialog form flow and dialog content grouping are Core-owned. |

-## Remaining Promotion Candidates
+## Audit Result And Deliberate Local Ownership
 
-The post-migration scan still finds domain-specific grids, but the repeated
-generic metric and property-list geometry is gone. Remaining grids are mostly
-unequal-track editors, visualizations, workflow facts, import mappings, and
-collection layouts. The next useful candidates depend on interaction semantics:
+The second scan compared exact CSS declaration bodies and JSX anatomy across
+every WebUI module after migration. All repeated generic structural candidates
+found in that pass were promoted: viewport frames, catalogue/list shells,
+filters, selectable lists, state panels, count badges, section frames,
+equal-column grids, section headers, metrics, and definition-editor chrome.
+The final legacy-baseline pass also migrated Access administration, Core
+Settings, Docs, Mail bounce processing, and Organizations to the shared page
+and workspace layouts and removed their copied responsive geometry.
 
-| Priority | Remaining pattern | Evidence | Proposed contract |
-| --- | --- | ---: | --- |
-| 1 | Empty and collection state anatomy | More than 70 module-prefixed empty/state class uses remain; only loading, alerts, blockers, and DataGrid empty actions are centralized | A composable `StatePanel`/`CollectionState` covering empty, recoverable error, permission block, partial result, and next action without hiding domain consequences. First distinguish a whole-surface state from a compact empty row or optional-value placeholder. |
-| 2 | Filter and search rows | More than 50 filter/search class tokens cover simple text search, facets, popovers, result counts, active filters, bulk selection, and overlay search | Define `FilterBar` only after the input/submit, live filtering, facet, result-summary, and bulk-action accessibility variants have been compared. Plain action placement already uses `ActionToolbar`. |
-| 3 | Assignment/picker groups | `admin-assignment-grid`: 5 uses in 4 files | Promote a selection/assignment composition only after its list, search, empty, policy, and permission variants are compared; plain geometry can already use `ContentGrid`. |
-| 4 | Repeated domain fact and statistic grids | `campaign-header-grid` (8), `review-flow-fact-grid` (6), `postbox-form-grid` (5), plus smaller families | Compare semantics before promotion. Some can use `ContentGrid` or `DescriptionList`; others intentionally own unequal tracks or workflow visualization. |
+The remaining cross-module declaration matches are not independent component
+anatomy. They are small token-based rules such as ellipsis, muted captions,
+uppercase terms, or flex-column containment applied to different semantic
+elements. Moving those rules into a component would erase meaning; their
+visual values already come from Core tokens. Remaining larger local layouts
+are deliberately domain-owned:
 
-The other custom grids are mostly bounded domain visualizations or unequal-track
-editors: conflict mappings, import mapping, campaign review facts, charts,
-calendar time views, connector synchronization, records lists, and definition
-editors. They should remain module-owned unless a second domain demonstrates
-the same semantics and interaction contract. A shared primitive should not be
-created merely because two implementations both use CSS Grid.
+- unequal-track editors, import mappings and schema/data tables;
+- calendar time grids, charts, graph node shapes and graph edge semantics;
+- file/mail/postbox/records explorer panes whose interaction contracts differ;
+- timelines, evidence histories, recipient compositions and policy-specific
+  detail sections;
+- compact list-row internals that cannot preserve their semantics through
+  `SelectionListItemContent`.
 
-## Next Audit
-
-The next bounded slice should compare whole-surface empty states across list,
-detail, permission, capability, and recoverable-error contexts and promote only
-their shared anatomy. Filter/search composition follows after its live versus
-submitted filtering and bulk-selection behavior is explicit. Assignment grids
-remain deferred until their permission and policy variants are understood.
+A future candidate is promoted only when a new audit identifies repeated
+structure plus the same responsive, accessibility and interaction contract.
+The enforcement script prevents regression for the patterns centralized in
+this pass and maintains the reviewed dialog-width baseline.
