fix(ci): get the MSRV job and cargo-deny green again - #1386
Conversation
Dependabot moved `dtolnay/rust-toolchain` from 1.94.1 to 1.100.0 in #1384. That ref is a Rust version, not a release of the action, so the bump was decided by comparing numbers: 1.100.0 is the larger, and it is also a Rust release that does not exist. Every pull request in the repository has failed since, in `Test Stable (MSRV)`, at error: could not download nonexistent rust version `1.100.0` before a line was compiled. The declared floor never moved -- `rust-version = "1.94"` in the root Cargo.toml -- so the pin goes back to 1.94.1 and the two agree again, which is the pairing the job's own comment asks for. The updater is told to leave this one alone as well, because nothing about the failure was specific to 1.100.0: any ref it picks is a toolchain it cannot know exists, matching a floor it cannot see. Raising the MSRV stays a two-line change made by hand, in the two places that have to move together.

The new comment repeats the Dependabot exclusion rationale already added in .github/dependabot.yml. Keeping the decision rationale in two places increases maintenance work and allows the copies to provide conflicting guidance when the MSRV policy changes.

An ignore is per dependency rather than per use, so excluding `dtolnay/rust-toolchain` also stops the SHA pin in `signal-durability-nightly.yml` being refreshed.

`bans` has been failing on every pull request, `main` included, on three duplicate entries: `getrandom` 0.3.4/0.4.3, `prettyplease` 0.2.37/0.3.0, and `r-efi` 5.3.0/6.0.0. None can be closed from our manifests. Each pair is two incompatible majors pulled by different parents: the workspace is on `getrandom` 0.4 through rand 0.10, while the `tempfile` inside buffa's codegen is on 0.3, and `r-efi` is whichever one each `getrandom` picked. Choosing either side leaves the other parent unsatisfied, and no version of ours is a parent of any of them. What decides it is where they are reached from: only through `buffa-build`, which every crate using it declares under `[build-dependencies]`. A build script runs at compile time and links into no shipped binary -- the same argument the proc-macro skips beneath these already make, which is why they sit next to each other. Also drops the RUSTSEC-2026-0150 ignore. `audiopus` is no longer anywhere in `Cargo.lock`, even under `--all-features`, so the entry excused a crate that had left the graph and cargo-deny was reporting it as `advisory-not-detected`. An ignore outliving the crate it excuses is how a real advisory gets waved through later under a name nobody rechecked. Verified with the CI command itself, cargo-deny 0.20.2, the version `taiki-e/install-action` resolves: `advisories ok, bans ok, licenses ok, sources ok`.

cargo-deny reports it as a yanked crate, reached through rand 0.10.2 and so present in every build. 0.10.2 is a patch release on the same line and the only lock entry that moves.

It also fails identically on #1385, and it is advisory by construction: the job's own summary step prints "Breaking changes detected. This does not block the PR — bump the minor version if the break is intended.", and the workflow comment notes the workspace is pre-1.0 and intentionally breaks API between minors. So it wants a version decision at release time, not a change here. Generated by Claude Code |

Dismissed because Cubic found issues in a newer review.
`Cargo.lock` carries a `rand_core` 0.9.5 entry listing `getrandom 0.3.4` as a dependency, which reads like a runtime route into the shipped graph and makes the skip beside it look like it is excusing a duplicate that ships. Nothing reaches that rand_core: `cargo tree -i rand_core@0.9.5 --target all` prints nothing, on any target. The entry is stale, and the build-dependency route is the only one there is. Worth writing down because a reviewer read it the other way within an hour of the skip landing, and the lock will keep saying it.

Test Stable (MSRV)— dies at toolchain install#1384 carried one line beyond the actions it meant to move:
That ref is a Rust version, not a release of the action. Dependabot compares the numbers, finds
1.100.0larger, and pins a toolchainrustup404s on — Rust 1.100 is roughly two years out. The declared floor never moved (rust-version = "1.94"), so the pin and the floor had also silently stopped agreeing, which is the exact rot the job's own comment says the pin exists to prevent.Back to
1.94.1, and Dependabot is told to leave this dependency alone — nothing about the failure was specific to 1.100.0: any ref it picks is a toolchain it cannot know exists, matching a floor it cannot see. Without that, next Monday's batch reintroduces it.That ignore is per dependency rather than per use, so it also freezes the SHA pin in
