Cranes
—
Agents are cranes. Directories are pallets. Work arrives at an induct and leaves by a spur. An external service is a truck — and a truck docks at the boundary and never drives onto the floor, which is the airlock drawn where you can see it. Drag to orbit, scroll to zoom, click anything. Then trip the E-stop and watch the floor refuse.
The real thing reads all of this from disk: cranes from session markers in
_os/exchange/bus/session/, pallets from the tree, inducts from REQ
rows, spurs from the surface directory. Here it is a simulation, which is why this page says so
in three places. A page with no live source that presents itself as live is the failure the
protocol names first.
The floor goes red, every crane stops, and the induct button refuses. A red floor takes no orders — and red outranks every other colour in the glance.
It has no controls, deliberately. A truck drops a load at a dock and that is the whole of its access. That is the airlock, drawn as a loading bay.
You are inside another whole warehouse, navigated identically. Every level is a floor, all the way down — same controls, nothing new to learn.
The demo doubles as a smoke test of the invariants in
protocol/09-FLOOR.md. It runs on load; add ?selftest=1 to the URL to
see it run in isolation.
