 ## Key Patterns
 
 - **Data persistence**: `this.saveData(this.data)` / `this.loadData()` — single object `{ settings, threads }`. Settings merge on load preserves new fields via per-entry spread for `promptButtons`.
-- **Streaming**: `ClaudeClient.streamChat()` is an async generator; `ChatView` iterates it and calls `updateLastMessage()` per chunk. (Note: `requestUrl` delivers the full response at once — no true streaming.)
+- **Streaming**: `ClaudeClient.streamChat()` is an async generator using native `fetch` with `stream: true` and SSE parsing (`content_block_delta` events). `ChatView` iterates it and calls `updateLastMessage()` per chunk. `chat()` and `fetchModels()` use `requestUrl` (buffered, fine for non-streaming calls).
 - **Context flow**: Query → `VaultSearch.search()` or `EmbedSearch.search()` → context preview → user confirms → `sendMessage()` injects note content into the Claude prompt. Auto-retrieve skipped when prompt extension buttons are active.
 - **Active search engine**: `plugin.activeSearch` returns `EmbedSearch` when enabled, else `VaultSearch`.
 - **System prompt layering**: base system prompt → optional `systemContextFile` → active `promptButtons` extension files (each appended with `\n\n---\n`).
