+The raw-HTML `html` node type is retired (objectui#13449). Its renderer wrote the authored `html` string into the page through `dangerouslySetInnerHTML` with no sanitiser, so anyone who could write metadata could put script-bearing markup in front of every viewer — a `kind: 'html'` page included, which compiled an `html` tag carrying an `html` attribute with no diagnostic. `@objectstack/spec` declares no `html` component, so it is removed rather than sanitised, at once, with no deprecation alias. This is breaking for a page that still names it; it is marked `minor` under this repository's version policy.
+
+- **SDUI node `html`**, also registered as `ui:html`. FROM: `@object-ui/components` registered both keys. TO: neither is registered. A JSON node that still names it draws the unknown-component panel, a `kind: 'html'` page that writes the tag fails to compile with `forbidden-tag` and `unknown-component`, and `objectui check` no longer counts either key among the known component types.
+- **Public block `html`** in `PUBLIC_BLOCKS` (`@object-ui/core`). FROM: listed as the curated tier's escape hatch, so `getPublicConfigs()` and the published `sdui.manifest.json` carried it. TO: not listed, so neither names it.
+- **Schema `HtmlSchema`** in `@object-ui/types`: the TypeScript interface from the package entry, with its `DataDisplaySchema` member and its `SchemaRegistry` row (so `ComponentType` no longer offers `'html'`), and the zod arm from `@object-ui/types/zod`. FROM: exported, and a `type: "html"` node validated against the arm. TO: there is no such export, so importing it fails to compile. `DataDisplaySchema` keeps a refusal arm for the literal, which is not exported, so `objectui validate` refuses a `type: "html"` node BY NAME at `type`, and the message names the remedy.
+
+The `html` FIELD type (`HtmlFieldMetadata`, drawn by `field:html`) is a different layer and stays: its value displays through the sanitised fields path.
+
+Fix for a page that still names it: in place of `{ "type": "html", "html": "…" }`, declare rich text a user edits as an `html` or `richtext` field on the object, whose value renders sanitised, and write authored page copy as a `kind: 'html'` page.

+ * objectui#13449 — the raw-HTML `html` node type is retired, and neither
+ * authoring surface can put unsanitised markup into the page any more.
+ *
+ * ## The defect
+ *
+ * `@object-ui/components` registered `html` (`ui:html` plus the bare key),
+ * whose renderer wrote the authored `html` string into a `div` through
+ * `dangerouslySetInnerHTML` with no sanitiser. `@objectstack/spec` declares no
+ * `html` component. Two doors reached it:
+ *
+ *   1. a JSON node `{ "type": "html", "html": "…" }`;
+ *   2. a `kind:'html'` page — the tier documented as parsed, never executed,
+ *      and safe for untrusted authors. Its compile whitelists every registered
+ *      type, so `<html html="…" />` compiled with NO diagnostic and the
+ *      renderer injected the string. Measured on the base before the fix: an
+ *      `img` carrying an `onerror` attribute reached the DOM through both doors.
+ *
+ * ## What each suite holds
+ *
+ *   1. the `kind:'html'` page refuses the tag at compile time and renders no
+ *      authored markup (red on the base: zero diagnostics, the `img` with its
+ *      `onerror` attribute in the DOM);
+ *   2. the JSON node draws the unknown-component panel and no authored markup
+ *      (red on the base: the markup was injected);
+ *   3. CONTROL — the same page without the retired tag renders its authored
+ *      content, so suite 1's absence is not a page that renders nothing.
+ *
+ * It lives in `apps/console` because the claim is about the whole registration
+ * graph: `@object-ui/fields` registers a `field:html` editor that must not take
+ * over the bare key once the display renderer is gone.
