+# Port: chore(deps): migrate AI SDK to v7 (#6636)
+
+**Upstream:** `dfbbfeb5a9ab3cbaf9582ba3393cceb1584baa5e` (nuxt/ui)
+**Decision:** skip (deferred — tracked for a deliberate AI-SDK-v7 adoption pass)
+
+## Upstream change
+Major AI SDK migration:
+- deps: `ai` `^6`→`^7`, `@ai-sdk/anthropic` `^3`→`^4`, `@ai-sdk/gateway`
+  `^3`→`^4`, `@ai-sdk/mcp` `^1`→`^2`, `@ai-sdk/vue` `^3`→`^4` (root + docs +
+  playground manifests + lockfile); root `package.json` marks `ai` an optional
+  peer (`^6 || ^7`).
+- docs/playground **client**: migrate every chat example + `Chat.vue` +
+  playground chat/sidebar pages from the `new Chat({...})` class (`@ai-sdk/vue`)
+  to the `useChat()` composable (`messages`/`status`/`error` become refs;
+  `sendMessage`/`regenerate`/`stop`; `input`/`handleSubmit` removed).
+- docs/playground **server**: rewrite `ai.post.ts`/`chat.post.ts`/
+  `completion.post.ts` to the v7 streaming API — `system`→`instructions`,
+  `stepCountIs`→`isStepCount`, `.toUIMessageStreamResponse()`→
+  `toUIMessageStream()` + `createUIMessageStreamResponse()`,
+  `.toTextStreamResponse()`→`createTextStreamResponse()`, `onFinish`→`onEnd`,
+  model ids bumped (`claude-sonnet-4.6`→`claude-sonnet-5`).
+- docs prose (chat/editor/migration guide) + the `skills/nuxt-ui` chat layout
+  reference updated to match. **No `src/runtime` component change** upstream.
+
+## b24ui decision — skip / defer
+This is a **major**-version dependency migration, not a mechanical port, and it
+touches b24ui surfaces upstream does not:
+
+- **b24ui runtime uses `ai`.** `src/runtime/components/{ChatMessages,ChatMessage,
+  ChatPromptSubmit}.vue` and `src/runtime/utils/ai.ts` import from `ai`. Upstream
+  changed no `src/runtime` file (its runtime was already v7-safe), but b24ui
+  adopting `ai@7` requires verifying b24ui's runtime still typechecks against the
+  v7 type surface (`UIMessage`, `ChatStatus`, etc.) — which the upstream diff
+  gives no guidance on.
+- **b24ui-only `bx-assistant` module.** `docs/modules/bx-assistant/`
+  (`AssistantPanel.vue`, `runtime/server/api/search.ts`,
+  `runtime/composables/useAssistant.ts`) is a b24ui fork addition that uses
+  `@ai-sdk/vue` + `streamText` with **no upstream counterpart** — it would need a
+  hand-authored, independently-tested migration to the v7 API.
+- b24ui keeps its own curated `ai`/`@ai-sdk` pins across root/docs/demo/nuxt (see
+  the cd52459 §2 port); a v7 jump must be mirrored and lockfile-regenerated with
+  the runtime + custom module verified end-to-end.
+
+Deferring is consistent with prior maintainer deferrals of non-mechanical,
+b24ui-divergent work (#220 InputRating, #194 Calendar). b24ui stays on `ai@6`
+for now; the v7 adoption should be a deliberate, separately-tested pass that
+migrates the runtime types **and** the `bx-assistant` module, not a diff replay.
+(Also noted: verbatim upstream `.patch` fetch is currently egress-blocked, so a
+faithful large-file replay isn't cleanly available this session.)
+
+No `src`/manifest change — bookkeeping only; ledger `decision: skip`, cursor
+advances. Tracked for a future AI-SDK-v7 migration task.
