Five big Python files wired together is not a weft program, it is a Python program the graph hides. -- Trying something out is done in weft too. Does this API answer, what does that endpoint return, what does the model say to this prompt: you write the node or the two-node graph and run it (`weft run --from`, the `weft-sdp` skill), never a throwaway script or a `curl`. The experiment is then already the program, its inputs and outputs are in the journal, and it grows from there instead of being rewritten. A script is the right tool only when weft plainly cannot express the question, and that is rare. Calling the program's own live routes is a different thing: that is how the website and other callers will reach them, so `curl -L` against a live route, with the key the route asks for, is the right test (the `weft-api` skill). +- Trying something out is done in weft too.

Your memory of it is stale. Search the PROBLEM ("render a scene headless in a container"), never the library or the version you already have in mind, so the results can show you what you did not know. If you catch yourself writing a version number or an API call from memory, stop and write: "Wait. Search first." - A slow job (minutes) never sits in one blocking call a caller waits on: answer early, run the work in the background, and show its progress on the infra node's display, or as a status the caller polls (the `weft-api` skill has the shape).
