## Task logs

- **Actions**: Created 6 VertexAI examples (demo, chat, streaming, vision, embeddings, tool_calling). Registered 12 new examples (6 Gemini + 6 VertexAI) in Cargo.toml. Fixed `StreamChunk` variant patterns, `ToolChoice::specific` → `ToolChoice::function`, `assistant_with_tool_calls` → `assistant_with_tools`, `ChatMessage::tool` → `ChatMessage::tool_result`, field access `tc.id` not `tc.id()`. Removed unused `ToolCall` import from gemini example. Fixed outdated unit test `test_create_embedding_provider_gemini_fallback` to accept both "gemini" and "mock" depending on env.
- **Decisions**: VertexAI examples mirror Gemini examples but use `from_env_vertex_ai()` constructor; streaming example uses `chat_with_tools_stream` with empty tools for chat-mode streaming since no `chat_stream` method exists.
- **Next steps**: Commit changes. Optionally run e2e tests with real API keys (`cargo test --test e2e_gemini -- --ignored`).
- **Lessons/insights**: `StreamChunk::ThinkingContent` is a struct variant (named fields), not a tuple variant. `ToolCall.id` is a `String` field, not an `Option<String>` method. The Gemini embedding factory test was outdated after embedding support was added.
