 A hand-authored `form` hands each field widget the `fields[]` entry itself as its metadata carrier. objectui#11070 graded that channel from a source read and missed keys on it. This change measures it at runtime through the real `SchemaRenderer`: a census records every key of the entry a reader asks for by name, and each key it found read and undeclared is rendered with and without, to show the widget acting on it. The census is a test (`form-field-channel-census-12130.test.tsx` in `examples/schema-catalog/test/`), so a key a widget starts reading without a declaration turns it red.
 
 - **Declared, by reference to `@objectstack/spec`'s `FieldSchema`:** `language` (the `code` widget), `maxSize` (`file`, `image`), and the lookup picker's `allowCreate`, `descriptionField`, `displayField`, `lookupColumns`, `lookupFilters` and `lookupPageSize` (`lookup`, `master_detail`, and for `displayField` / `lookupFilters` the `user` widget too). Each is the spec member itself, value checks included.
-- **Declared, by reference to the field metadata types:** `idField` (`LookupFieldMetadata`), `picker` and `subtitle` (`UserFieldMetadata`), read by the `lookup` and `user` widgets.
+- **Declared on the `FormField` entry itself:** `idField?: string`, `picker?: 'search' | 'default'` and `subtitle?: string[]`, read by the `lookup` and `user` widgets.
 - **Declared as the widget reads them, since no type declared them:** `capture` (`'environment' | 'user' | false`, the `file` widget's camera input), `crop` (`boolean`, `false` turns off the `image` widget's cropping) and `defaultName` (`string`, the name an empty `avatar` draws its initials from).
 - **TypeScript.** `FormField` gains each member, typed as above. Each used to fall to the index signature's `any`, so a typed literal with a value of the wrong type is now a compile error.
 - **zod (`@object-ui/types/zod`).** WIDENS on the strict authoring face (`StrictAnyComponentSchema`): each key used to be refused with `unrecognized_keys`, and now parses. NARROWS on the tolerant face (`safeValidateSchema`), where each key used to be stripped unjudged: a value of the wrong type (a `maxSize` that is not a positive whole number, a `lookupFilters` operator the spec does not list, a `picker` other than `search` / `default`) is now refused, and the values are now kept. The face is flat: each key is accepted on every field type, and only the widgets named above read it.
