Transaction Science c84ca0ec44 WIV1 and WIR1 gate 4 (WIP, committed before running): the differential against the direct decodes
tests/int_ops_differential.rs gains two halves, each behind its decoder's
feature (video_int, staged), which the fast-kernel steps and now the nightly
workflow carry:

- int_video_random_clips_decode_alike: random clips (partial block grids,
  both precisions, q to 65535, tables of 3 to 64 entries at offsets to the
  ends of i32, vectors anywhere in i16, keyframe 1 with its I-frame, escaped
  and extreme residuals, a broken field one clip in 64, damaged streams)
  through int_video::ops and int_video::legacy: the same frames or the same
  refusal, and no panic.
- wir1_random_layers_apply_alike: random layers of every kind and predictor
  (rates to 2^20, small tables so most residuals escape, q to 65535, one table
  or one per unit) coded by the reference encoder, a stream damaged one layer
  in eight, a unit applied to another shape or type one in sixteen: every
  unit and the streams' check alike, no panic.

There is no planned break: integer-operators §15.3 lists none for these
decoders, so the oracle is equality.

name: wai-ops differential (nightly)
# Each integer decoder that decodes through the integer operator set
# (wai/extensions/integer-operators.md) against its direct decode (the test-only
# `legacy_int` feature), on random parameter sets and payloads, for an hour under each
# build profile: with overflow checks on and with them off. Outside the planned breaks
# of integer-operators §15.3 the two decode to the same bytes or both refuse, and the
# direct decode never panics; under a planned break the decode through the operator set
# refuses (wai/wai-rs/tests/int_ops_differential.rs). Today: wai.neural.int_synth,
# wai.splat.int_codec, wai.audio.int_codec, wai.neural.int_hyper (whose decode is
# also the keyframe of wai.video.int_hyper), wai.neural.int_mlicpp, wai.world.model's
# integer renderer, against its direct renderer with the direct guard, and
# wai.image.jpegai's scale path and entropy decodes, against its direct computation,
# which panics (or, without overflow checks, may compute on) where the operator set
# refuses a stream; and WIV1 (wai.video.int_motion, the P-frames of wai.video.int_hyper)
# and WIR1 (the four int_refine capabilities), which decode through the stage operators
# alone and make no planned break.
#
# Each night starts from its own seed, the date, which the log prints; a failing case
# names its seed, and `WAI_DIFF_SEED=<seed>` re-runs it. The same tests run for a fixed
# count on every push, in wai-conformance.yml's fast-kernel steps.
# One run per branch at a time. A push supersedes the run before it.
