+**`marketplace.installedAdditiveNote` is plain text in all ten packs** (objectui#12610). Each value dropped its leading `Note:` markup (in that pack's language); the sentence after it is unchanged. The console draws the key as the tooltip of Installed Apps' Uninstall, which renders text, not HTML. The key's name does not change.
+
+**Clause-②: yes.** The value is part of the published `en` pack and its nine siblings. A consumer that rendered this key as HTML now renders the same sentence without the bold "Note:" prefix; one that rendered it as text no longer shows literal tags.

+**Installed Apps' kernel note is the tooltip of the Uninstall it qualifies** (objectui#12610). The "kernel API is additive only" note was a paragraph at the foot of the list, shown under the empty state too. It now opens as a tooltip on hover or focus of a loaded local row's Uninstall, and is that button's accessible description. A not-loaded row's Uninstall carries no note, since that package left nothing in the running kernel (objectui#11645), and a cloud-bound list, which offers no Uninstall, carries none either. The note renders as text; the widget no longer passes it through `dangerouslySetInnerHTML`.

+**A settings action row draws its label once, on the button** (objectui#12610). The settings renderer's `action_button` row printed the manifest's `label` as the row label and again on the button, so Mail Delivery read "Send test email" twice and AI & Embedder repeated "Test connection", "Reset to environment defaults" and "Test embedder". The button now carries the label alone. The row's left side holds the specifier's `description` when the manifest declares one, as one line of muted text, and nothing otherwise. Settings keys, values and save behaviour do not change.

+/**
+ * Installed Apps' kernel note rides the Uninstall it qualifies, as a tooltip,
+ * instead of a paragraph under the list (objectui#12610).
+ *
+ * The settings walk measured the "kernel API is additive only" paragraph under
+ * the EMPTY state, where there is nothing to uninstall. The note says what
+ * Uninstall does to a loaded package (the running kernel keeps it until
+ * restart), so it belongs on that action, and only where it applies:
+ *
+ * - the empty state carries no note;
+ * - a loaded local row's Uninstall is described by the note and opens a
+ * tooltip with it, as plain text — no markup is drawn literally;
+ * - a not-loaded row's Uninstall carries no note: that package left nothing
+ * in the running kernel (objectui#11645);
+ * - every pack's value is plain text, since a tooltip renders it as text.
+ *
+ * The wire is stubbed `fetch` against the REAL `marketplaceApi`, as the
+ * not-loaded file beside this one does; text is the PACK's value for its key,
+ * through the real `I18nProvider`, never a sentence copied into this file.
