wasm-jit — software with no fixed screen

Describe what you want and the interface appears in milliseconds — compiled to a capability-fenced WebAssembly cell that can only touch what you explicitly allow. Safe by construction, not by review. That is the whole bet.

The one-minute proof (live in the playground above, with JavaScript on): a generated seed that calls fetch() is refused at compile time — “unknown function 'fetch' — granted capabilities: [sin, cos, hue, rgb, hsl, disc, ring, arc, line, glow]”. The import table is the module’s entire world; a capability never granted cannot be seized, however clever the generator.

A first-person night-river world (the Tang poem 楓橋夜泊 / Mooring by Maple Bridge at Night) grown entirely from a fixed vocabulary: a stone arch bridge, a boat with a lit fishing lantern, a temple with a bell, autumn maples, crows, falling snow

Structure is typed data, manifested by a fixed host vocabulary (the DOM analogue of the 10 draw primitives). The sky and the compiler above are the WASM cells; this renderer is the trusted shell.
