Binder

Binding straight to an API field.

A feed pane browses the poller's own response shape. The tree comes from the last successful probe, stored on the unit, so the pane works before anyone presses Fetch.

• Fetch sample calls the feed once, server-side, and stores the payload as the sample. The page must be saved first — a probe runs on the server.
• Fields the feed already writes are marked linked; picking one reuses its mapping rather than minting a second writer for the same value.
• Picking an unmapped field creates the field mapping and binds the slot to it in one step.
• With no sample yet, the pane still lists the fields the feed already writes, so you can bind without probing.
