+refactor(spec)!: reconcile the SDUI component props with the renderers that serve them — 4 keys retired, 9 declared (#5775)
+
+#5068 wired the first parse `ComponentPropsMap` ever had, and the corpus it
+landed on diverged in **both** directions: keys objectui's renderers honour that
+the schema never declared, and keys the schema declared — one of them
+**required** — that no renderer has ever read. Maintainer ruling (2026-08-06),
+direction A: the #5611 rule again, *the delivered and authorized shape is the
+contract*.
+
+The sharpest case is the record picker. It required `displayField`, which
+appears in no renderer; `record-picker.tsx` resolves `props.labelField ?? 'name'`
+and renders `row[labelField]`. So an author who followed the schema and wrote
+`displayField: 'title'` got a dropdown listing `name`, with a success receipt and
+no diagnostic anywhere — ADR-0078 exactly. Two spellings of one concept, of which
+only the undeclared one was ever read.
+
+**FROM → TO**
+
+| was | now | fix |
+|---|---|---|
+| `element:record_picker` `displayField: string` (**required**) | `labelField?: string` | Rename the key; the value (a field name) is unchanged. Optional now — the renderer defaults to `name`. |
+| `element:record_picker` `searchFields?: string[]` | *(removed)* | Delete the key. Use `filter` / `dataSource.filter` to restrict what the picker offers. |
+| `element:record_picker` `multiple?: boolean` | *(removed)* | Delete the key. Multi-record selection is not implemented on this element. |
+| `page:card` `body?: Component[]` | `children?: Component[]` | Rename the key; the value is unchanged. `footer` is a distinct slot and is untouched. |
+
+`searchFields` and `multiple` go under ADR-0049 enforce-or-remove: the control is
+a single-select `Select` with no search input, binding **one** record id into a
+page variable — so `searchFields` narrowed nothing and `multiple: true` selected
+nothing extra while reporting success. Either returns the day the capability is
+implemented (#5021 / #4988 precedent); a declaration is not a roadmap.
+
+Newly **declared**, because the renderers already honour them (nine keys, no
+behaviour change — this is the schema catching up):
+`element:record_picker` `labelField` / `valueField` / `label` / `emptyText`;
+`record:path` `stages[].terminal` (`'won' | 'lost'`, honoured ahead of the
+renderer's value/label token heuristic); `page:tabs` `items[].value` (the stable
+`?tab=` URL token) and `items[].count`; `page:card` `children`; and `children` on
+`page:section` / `page:footer` / `page:sidebar`, which were declared `EmptyProps`
+— "zero props" — while all three renderers render a child list.
+
+The retirement kit:
+
+- Four `retiredKey()` tombstones in `ui/component.zod.ts`, each carrying its own
+  prescription. `ComponentPropsMap`'s entries STRIP, so a bare deletion would
+  have replaced one silent no-op with another; a tombstone types the key `never`
+  (tsc at the authoring site) and raises the prescription at parse time.
+- **ADR-0087 D2 conversions + D3 chain step** —
+  `record-picker-display-field-to-label-field`, `record-picker-inert-keys-removed`,
+  `page-card-body-to-children`, all `retiredFromLoadPath`, so `os migrate meta`
+  rewrites sources and the loader stays loud. Region level is the reach, as for
+  `page-header-subtitle-alias`: `PageComponentSchema` declares no children key, so
+  a component nested inside another's `properties` is covered by the tombstone
+  rather than the walk.
+- `RETIRED_KEYS_BY_MAJOR[17]` entries for all four keys; baselines
+  (`authorable-surface/ui.json`, `json-schema.manifest/ui.json`, `api-surface/ui.json`)
+  and reference docs regenerated.
+- Pins both ways: the prescription is asserted per key, and a clean parse is
+  asserted not to materialize any of them.
+
+Not in scope, deliberately: `page:card.visible` is a component-level visibility
+predicate written into `properties` and hoisted by the renderer — a page to
+rewrite onto the ADR-0089 `visibleWhen`, not a key to declare.
+
+No runtime behaviour changes. The renderers already read the declared spelling of
+every key, and the four retired ones never had an effect to lose.
