+
+Correct a false clause in the `header-bar` refusal messages and in nine `body?: never` docblocks (objectui#10959).
+
+The `HeaderBarSchema` refusals for `title`, `logo`, `nav`, `left`, `center`, `right`, `sticky`, `height` (objectui#10387) and `variant` (objectui#10286) said an authored value drew "no error, no warning". So did the `body?: never` docblocks on `box`, `span`, `container`, `flex`, `stack`, `grid`, `scroll-area`, `toggle` and `form` (objectui#8284), which ship in the emitted `.d.ts`. The render path is as described, but the parser tier is not: `validateTree` answers each of those keys with an `unknown-prop` warning. So the refusals now say "no render-time error or warning and no element; only the parser tier's `unknown-prop` warning noticed it" (`variant` keeps "no class" where the others say "no element"), and the docblocks say the `body` "rendered an EMPTY element with no render-time error or warning; only the parser tier's `unknown-prop` warning noticed it".
+
+Message, `.describe()` and documentation text only: every document is accepted or refused exactly as before, with the same issue code at the same path. Every other word of each message and docblock is unchanged.

+/**
+ * objectui#10959 — what an unread `header-bar` key and an unread `body` drew,
+ * stated for BOTH tiers. The sibling of objectui#10928, with a different code.
+ *
+ * Two families of published text said an authored value drew "no error, no
+ * warning":
+ *
+ *   - the `HeaderBarSchema` refusals of objectui#10387 (`title`, `logo`, `nav`,
+ *     `left`, `center`, `right`, `sticky`, `height`) and objectui#10286
+ *     (`variant`), on the zod face (message and `.describe()` are one string);
+ *   - the `body?: never` docblocks objectui#8284 put on the nine nodes whose
+ *     renderer reads `children` (`box`, `span`, `container`, `flex`, `stack`,
+ *     `grid`, `scroll-area` in `layout.ts`; `toggle`, `form` in `form.ts`),
+ *     which ship in the emitted `.d.ts`.
+ *
+ * The render half is true: the value changed nothing on the page and logged
+ * nothing. The warning half was false. The parser tier's `validateTree`
+ * (`@object-ui/sdui-parser`) answers a key its registration does not declare
+ * with `unknown-prop`, and `header-bar` declares only `crumbs`, `search`,
+ * `actions` and `rightContent`. It answers `body` the same way on these nine,
+ * whatever its shape, because each of them declares the `children` input:
+ * `checkRetiredBodyDialect` gives `not-a-container` only where that input is
+ * missing, which is why objectui#10928's clause would be false here. So the
+ * clause now names `unknown-prop`:
+ *
+ *   refusal strings: "no render-time error or warning and no element; only the
+ *                     parser tier's `unknown-prop` warning noticed it"
+ *                    (`variant` says "no class" where the others say
+ *                     "no element", as it did before)
+ *   docblocks:       "rendered an EMPTY element with no render-time error or
+ *                     warning; only the parser tier's `unknown-prop` warning
+ *                     noticed it"
+ *
+ * ## Why this file pins the prose, and where the parser half lives
+ *
+ * `@object-ui/types` declares no workspace dependency and its tests import
+ * none, so `@object-ui/sdui-parser` is not importable here without declaring
+ * it (the same reason as objectui#10928's pin). The `body` half of the parser
+ * behaviour is pinned in `packages/sdui-parser`: "the retired `body` spelling
+ * follows the SAME predicate" in `containment-declared-slot-9910.test.ts`, and
+ * "a `body` child list under a CONTAINER draws `unknown-prop` naming
+ * `children`" in `body-dialect-6771.test.ts`. The `header-bar` half is the
+ * generic undeclared-key branch of `validateTree`; no pin names `header-bar`
+ * there. The live-registry reading taken for this change (every key above, on
+ * `header-bar` and `ui:header-bar` and on the bare and `ui:` key of the nine,
+ * with a render leg and a `not-a-container` control) is on objectui#10959's
+ * pull request: a record of one run, not re-derived here.
+ *
+ * ## What is pinned, and what is deliberately not
+ *
+ * The clause as a substring. On the zod face: one `header-bar` key of each
+ * clause form, read through its refusal with its code and path, then every
+ * `header-bar` member whose refusal is one of these two retirements. On the TS
+ * face: the `body` docblock of `BoxSchema` and of `FormSchema`, then every
+ * docblock in `layout.ts` and `form.ts` that carries objectui#8284's sentence.
+ * The rest of each string is NOT pinned; `header-bar-unread-keys-10387`,
+ * `mirror-groups-cd-10286` and the objectui#8284 pins read it.
