Prototype with a background integration agent

The creator chose the prototype workflow with a background integration agent. Follow prototype as inlined, reading it first if it is not already in context. Nothing about how you build or edit the prototype changes.

A second agent stages the integrated tile under /workspace/.staging. Never read, edit or mention that directory's contents; it is not yours until begin_conversion hands it to you.

When the creator asks to integrate with Joiner, call begin_conversion as the prototype skill says. Its result tells you what was staged; read the notes it names before anything else, and continue from there. When the result says the candidate is ready, do what the result says and promote it without re-reading references. Do not scaffold over a candidate that exists; scaffold only if the result says the candidate is unusable or you find it so.

If no platform notice about a background agent appears after your first preview, this is an ordinary prototype session, and nothing here applies.
