 ## Highlights
 
 - **Visual flow builder** — compose workflows on an intuitive drag-and-drop canvas. Flows are deliberately simple: no loops, no sub-workflows, no expression language to learn.
-- **Describe it, don't configure it** — give a node plain-language instructions and an LLM fills in its parameters at run time. Anything you set explicitly always wins over what the model infers.
+- **Describe it, don't configure it** — give a node plain-language instructions and an LLM fills in its parameters at run time. Anything you set explicitly always wins over what the model infers. This one and flow generation are the only features that need a key of your own (Gemini); both are off by default. Everything else — the canvas, triggers, the MCP server, every integration node — works on a fresh install.
 - **Built-in MCP server** — every integration node doubles as an [MCP](https://modelcontextprotocol.io) tool. Point Claude (or any MCP client) at your BlockNext server with an API key and use your connected services from chat.
 - **AI-powered nodes** — LLMs and generative AI (text, image, audio, video) as first-class building blocks, alongside integrations for the tools you already use.
 - **Async done right** — long-running AI jobs (video, music generation) are a single node. The node starts the job, polls the provider, and returns the finished result — no wait/check/loop scaffolding on your canvas.

Implements `NodeManager` (getter interface).

-  A node describes how it looks and how it connects, so the UI derives nothing: the artwork lives under `apps/platform/public/assets/icons/{brands,glyphs}/` and is composed at render time. `system_starter` declares an empty `Inputs` slice (no way in), `system_condition` declares two outputs labelled True and False. Credentials (`CredentialIcon`) and MCP servers (`ServerIcon`) name a `Brand` only — the glyph badge belongs to individual nodes.
+  A node describes how it looks and how it connects, so the UI derives nothing: the artwork lives under `apps/platform/public/assets/icons/{brands,glyphs}/` and is composed at render time. `system_starter` declares an empty `Inputs` slice (no way in), `system_condition` declares two outputs labelled True and False. `system_annotation` is the one `note` node: it is registered in the node catalog so both the UI and the flow generator can offer it, but it has no executor and is absent from the MCP `Tools` slice; `taskrunner.RunnableNodes` drops it before the DAG is built, so it never gets a node execution. Credentials (`CredentialIcon`) and MCP servers (`ServerIcon`) name a `Brand` only — the glyph badge belongs to individual nodes.
 - **Executor** (`domain/executors/executor.go`): the behavior for a node, keyed by the same ID. `ExecutorManager.ExecuteWithContext(ctx, credentials, data)` is the execution entry point.
 - **Credential** (`domain/credentials/credential.go`): a provider auth descriptor — schema, `IsOAuth1`/`IsOAuth2`/`IsSupportPlatform`, `SupportedNodes`. OAuth credentials may implement `RefreshableCredential`. `IsSupportPlatform` is auto-derived at load (host-provided OAuth apps).
 - **Adapter** (`domain/adapters/adapter.go`): a trigger adapter that maps a raw webhook payload into a `TriggerContext` (`source`/`sender`/`prompt`/`payload`, exposed as `$trigger.*` variables).
