Two real Session minds run the wants-gated barter
world right here in WASM — no server, no canned trace. Each mind is a
fork of one grounded world, scoped to its own trades; it follows its
plan while the free suffix replay holds and spends a bounded think only when
something breaks. Under fog, truth lives in a separate world session:
a mind sees its own stall each turn and its partner's on arrival —
everything else is belief. Hit steal mid-run and watch the
difference between knowing and finding out.
