int_world::{decode, decode_deltas, decode_planes} render through world/1 and
return a Result; int_world::{load, World} hold the set lowered and loaded once,
with step, step_delta, step_action and render for the live path, which replace
the per-row step functions of a parsed model. int_world::legacy is test-only
(legacy_int). wai-web's WorldModel loads its set once and renders through it;
its methods throw on a refusal.
Callers moved: tests int_world, int_world2, int_world_shared,
int_kernels_vectors; the int_world_decode example; the decode bench's world
row. tests/int_world_memory.rs (its own binary; both fast-kernel steps): a
clip, a step and a frame hold no more than the direct renderer's.
Text: integer-operators' status note, §13.5 (before the first frame: the
plan, T giving the shape back, the informative codes), §15.3 items 2 and 3;
SPEC §8's planned breaks; CHANGELOG.

//! `wai.world.model` integer renderer — a generative INTERACTIVE world whose every
|
|
//! frame is byte-exact. The committed transition + synthesis models, an initial
|
|
//! latent, and an action walk regenerate a frame sequence whose per-frame and clip
|
|
//! hashes reproduce on every machine — replay-equivalence for a *generated* world.
|
|
//! Committed tiny vector under `tests/vectors/int_world/`; never skips.
