mapErr translates manager errors into LLM-facing messages so the model gets actionable guidance (re-read, compact, etc.) instead of an opaque internal

AsInputString returns the union data inside the Input as a InputString

AsLLMProviderConfig returns the union data inside the ExternalResourceConfig as a LLMProviderConfig

AsMQTTConnection returns the union data inside the ExternalResourceConfig as a MQTTConnection

Chat forwards a chat request through the backend's /llm/generate route. The backend dispatches it to whichever underlying provider owns the model.

DeleteFile removes a previously uploaded file from the LLM service using its FileID. After deletion, the file can no longer be referenced in new reque

Flush discards buffered input.

FromMQTTConnection overwrites any union data inside the ExternalResourceConfig as the provided MQTTConnection

FromUserMessage overwrites any union data inside the ChatCompletionRequest_Messages_Item as the provided UserMessage

FromUserMessageContent0 overwrites any union data inside the UserMessage_Content as the provided UserMessageContent0

Health verifies the health of all configured providers. It returns an error if any provider is unhealthy.

Health pings the backend's LLM service and returns nil if every configured provider on the backend is healthy.

NewHTTPWriter constructs a writer that POSTs each log line to url. An empty headerName disables the auth header; otherwise headerValue is sent as head

NewHandoff creates a new Handoff tool that invokes the given agent.

NewProvider builds a Provider under the default "SelfHosted" id from a validated Config. Returns nil if the config has no models (defensive — Validate

NewToolNode creates a new ToolNode

RegisterNodeOutputs declares zero values for an emitter node's outputs into the scope.

UploadFile uploads a file (text, PDF, image, etc.) to the LLM service. Returns a FileUploadResponse containing the FileID that can be referenced in fu

WriteAnalog writes the given voltage (millivolts) to the channel.

Convert an AvailableVariable into a canonical Reference (srcId + varId).

Collect all output variable names currently in the store.

* Walk a node instance and rename any emit bindings/declarations whose name collides * with `existingNames`. Mutates in place. Handles all three loca

* Build the initial `arguments` record for a new channel: each parameter * that's active for the chosen `type` and has a `default` gets seeded.

emit sends an event to the event handler if one is configured.

enabled reports whether a path was configured.

* Filter a canvas's variables down to the declared-kind entries (the only * variety the api persists). Node-output and fnarg variables are * reconst

hasSubscribers reports whether any subscriber is registered; channels use it to skip wiring the driver callback when nobody is listening.

Check whether a node already has tool-input edges (for mutual exclusion).

inferProvider selects the appropriate Provider for the given model

initialize declares and sets user-declared variables in the scope.

True if a Host header or URL hostname is a loopback name ("localhost", "127.0.0.1", "[::1]"), with or without port.

stringExpr is a tiny helper for literal-string expressions with no references.

optFromString converts a string to param.Opt[string], treating empty string as omitted
