This repository had four different answers to "what Rust does this need":
rust-toolchain.toml 1.98.0 (the pin CI actually installs)
59 Cargo.toml files 1.97 (rust-version)
1 Cargo.toml file 1.88 (rust-version)
INGEST.md 1.95.0 ("CI enforces both")
The floor was enforced in exactly one place -- `wai-quantum-webgpu.yml` ran
`cargo +1.97.0 check` against one crate's one feature. So 59 manifests declared
a minimum nothing verified, and the top-level document told readers a version
that had not been the pin for some time, crediting CI with checking it.
The policy is to track the latest stable. That makes a floor below the pin
something this repository does not promise, so the unenforced check goes, and
the documents stop claiming a version and an enforcement that were not there:
- `wai-quantum-webgpu.yml`: the `MSRV 1.97.0` step, the second toolchain its
install step existed to fetch, and `MSRV` in the job's name.
- `INGEST.md`: states the pin at the root, that CI installs exactly it, and
that there is no floor beneath it.
- `openpay/README.md` and `openpay/docs/00-foundation.md`: both named 1.95
as the toolchain, and the README credited CI with enforcing an MSRV.
A version written in a document is a claim like any other. Stating 1.95 while
the pin is 1.98.0, and "CI enforces both" while one crate was checked, is worse
than stating nothing -- it reads as verified.
**Not done here, deliberately.** The 59 `rust-version = "1.97"` keys and the one
`1.88` stay for now. Removing them is not the small change it looks like: most
member crates inherit via `rust-version.workspace = true`, which fails to parse
the moment the workspace key is gone, so it is a coordinated edit across
hundreds of manifests rather than sixty. The key also has value independent of
any promise, since it turns an old toolchain into a clear message instead of a
compile error. What it must not do is state a floor nobody checks, so the
options are to delete it everywhere or to move it with the pin -- a decision
with consumer-facing consequences, which is its own change.
