Latest stable (1.98.0, released 2026-08-18). The pin lives in more places than
is obvious, and missing one means CI silently builds an older compiler than the
dev box:
- rust-toolchain.toml at the repo root
- eoc/eoc-rs/rust-toolchain.toml, a second toolchain file
- five CI workflows that hardcode a version instead of deferring to the file
(wai-conformance, wai-neural-e2e, wai-byte-equality,
joule-code-conformance, jouleclaw-public-surface-documented)
standards-build.yml needed no change, because it reads the toolchain file
rather than pinning inline. That is the pattern the other five should adopt.
MSRV raised to 1.98 across 26 manifests, following the earlier decision to have
the declared floor track the pin rather than drift behind it. Note this is a
support-policy change, not a mechanical one: it narrows which compilers can
consume these standards as libraries.
The pin stays exact, never `stable` — a pin that drifts is not a pin.

# WAI's load-bearing claim is bit-exact reconstruction on every machine,
|
|
# no tolerance parameter. This workflow enforces it mechanically: every
|
|
# cargo-class corpus — and the one neural decoder that can make the same
|
|
# promise, the integer-synthesis path (i64-only, no float ONNX) — is
|
|
# re-derived on a four-platform matrix (x86-64 + arm64 across Linux, macOS,
|
|
# Windows) and must reproduce its frozen BLAKE3 hashes; and the integer
|
|
# byte-equality goldens (rANS / int_synth / JPEG-AI mANS, generated once on
|
|
# a reference machine) must decode identically everywhere. All of it is pure
|
|
# Rust (no C codec chain, no ONNX Runtime), so the matrix needs no system
|
|
# dependencies.
