GPT's auto-wiring (4afee83) was checked on the isolated test ComfyUI. A splice behind
a node, a new branch, the branch choice and the loop check each took one call. A
ControlNet still failed both ways, because its positive and negative have the same
type as a sampler's. A LoRA after a checkpoint wired only its MODEL line.
- Same-type sockets of the same name pair up (positive to positive).
- wire_to into an input that is already fed puts the new node in front: the old
source now feeds the new node's matching input. A ControlNet before a KSampler
is 6 links in one call; a LoRA before the sampler and both prompts is 5.
- insert_after splices every type a node passes through.
- add_node errors call the new node #new instead of #-1 and say how to pick sockets.
- frontend.md: the canvas_wiring paragraph moves from Verification to the
mutation rules.
