The typed buffers are slices: words/floats/fixeds/doubles/pointers(n) make
zeroed, bounds-checked []int/[]float/... and the type names mean them. buffer(n)
is a []byte, with text_of, Fs.read_bytes/write_bytes and view(xs, start, n).
bytes(), indexing a raw pointer or bytes, free, resize, Memory.*, raw file calls,
data_of and C externs are refused outside unsafe { } / unsafe function, and a
project's own files may write unsafe only with --unsafe; the runtime and packages
are the platform. A slice passed to an extern goes as its data.
What the change found: Sync's atomics on a slice header, words(n) uninitialised,
input's fixed axes in ints, truetype's fixed outlines as ints, skin matrices
typed int, gl_shader's source table made from raw bytes. render3d gets safe
entry points (safe_api.ludic). Rendering is byte-identical; a frame costs the same.

# net_echo.ludic — N0: the transport seam (NETWORKING-DESIGN §5, §13 N0).
|
|
#
|
|
# The transport is two calls — net_send puts a datagram on the wire, net_poll
|
|
# takes the next one off. A production build binds them to a real socket with
|
|
# `extern fn net_send/net_poll` (UDP native, WebRTC/WebSocket wasm); absent that,
|
|
# the compiler supplies a built-in in-process loopback, so a program is networked
|
|
# end to end with NO foreign host — pure Ludic. This sends four bytes and polls
|
|
# them back through the loopback: prints 4, then 10 20 30 42.
