"""Assembles the tool result, in vmd's words rather than the agent's. WHY THE AGENT DOES NOT WRITE ITS OWN REPORT There is a path from a script running in the VM to the main model's instructions: guest stdout -> the agent's context -> the agent's summary -> the vm_agent tool result -> the main model. Tool output is the one thing this model reliably treats as fact, which makes that path worth something to anybody who can get a file into a project folder - and every caller shares those folders. So the facts in this report are produced here, from vmd's own record: what ran, what exited non-zero, what was committed, what the supervisor saw when it re-ran the check. The agent's prose is included, because throwing it away would lose the only explanation of *why* - but it is fenced, capped, and labelled as what it is. Two specific things are scrubbed: * `data:` URIs. budget.cap() passes a tool result that IS a data URI through untouched, and Open WebUI routes such a result to the model as a vision input. A guest that printed one as its entire output would be choosing an image for the main model to look at. * the fence itself, so a summary cannot close the quote early and continue outside it.
