1. Obtain `VLLM_CPP_RELEASE_COMMIT` from the independent approval of the exact release commit. Never derive the expected value from the current checkout.

## Validate

Run the mandatory Linux x86_64 CPU gates from the pinned shell:
Run the mandatory Linux x86_64 CPU gates directly with the native Cargo and Just workflows:

```console
env -u VLLM_CPP_TEST_MODEL nix develop -c just ci
nix develop .#msrv -c just msrv
env -u VLLM_CPP_TEST_MODEL just ci
RUSTUP_TOOLCHAIN=1.85.0 just msrv
# Equivalent exact-toolchain invocation: rustup run 1.85.0 just msrv
cargo check --locked --workspace --all-targets --features vllm-cpp/serde
RUSTDOCFLAGS='-D warnings' cargo doc --locked --workspace --no-deps --features vllm-cpp/serde
git diff --check
```

`just ci` includes formatting, warnings-denied lint/docs, model-free workspace tests, generated bindings and ABI conformance, four CPU link modes, the native C API fixture, model-free ASan/UBSan/leak checks, package/extracted/downstream validation, and no-upload publish dry-run. Run the exact MSRV gate separately so stable-toolchain success cannot mask it.

Nix support remains an optional convenience, not a prerequisite. Maintainers who choose it may run `nix develop -c env -u VLLM_CPP_TEST_MODEL just ci` and `nix develop .#msrv -c just msrv`; `nix flake check --no-build` is an additional Nix-specific evaluation check, not an ordinary release gate.

Prepared-Qwen inference/sanitizers, native-only TSan, successful Rust MiniMax-H3 generation, Miri, Linux ARM64, Apple ARM64, Vulkan, CUDA/CUTLASS/Triton, Metal/MLX, and accelerator runtime are optional or deferred. Record one only when it ran against the exact candidate; configured workflows and older results are not candidate evidence.

## Inspect packages

`just publish-dry-run` uses Cargo's sys-first workspace order with `--no-verify` and never uploads. It cannot provide the safe crate's full registry-resolution verification before exact sys `0.0.2` is available from crates.io. Check both crate-version slots are available before any future upload; do not reserve or publish them during candidate preparation.

## Inspect registry state

Use the exact-version crates.io API read-only. This helper classifies only HTTP 200 with matching crate/version JSON as `accepted` and only HTTP 404 as `absent`; network errors, redirects that do not finish in either status, other HTTP statuses, and malformed or mismatched JSON are `ambiguous`. Stop on `ambiguous`.

```bash
set -euo pipefail
command -v curl >/dev/null
command -v jq >/dev/null
registry_tmp=$(mktemp -d)
trap 'rm -rf "$registry_tmp"' EXIT HUP INT TERM

registry_state() {

if ! body=$(mktemp "$registry_tmp/response.XXXXXX"); then

sys_state=$(registry_state vllm-cpp-sys 0.0.2)
safe_state=$(registry_state vllm-cpp 0.0.2)
rm -rf "$registry_tmp"

printf 'vllm-cpp-sys 0.0.2: %s\nvllm-cpp 0.0.2: %s\n' \

```

The helper performs no registry mutation. Preserve its output with the release evidence. Before an initial sys upload, both states must be `absent`. Before any safe upload or retry, sys must be `accepted` and safe must be `absent`. If safe is already `accepted`, never republish it. Any other combination requires stopping for diagnosis.

## Publish

Only a separately authorized maintainer may publish from the exact reviewed commit with a clean root and detached submodule. Publish sys first:
Only a separately authorized maintainer may publish from the exact reviewed commit with a clean root and detached submodule. Rerun the reviewed-root guard immediately before each upload. Publish sys first:

```console
cargo publish -p vllm-cpp-sys --locked
# Wait until crates.io serves exact vllm-cpp-sys 0.0.2.
# Wait until the exact-version helper reports sys accepted and safe absent.
cargo publish -p vllm-cpp --locked --dry-run
cargo publish -p vllm-cpp --locked
```

The full safe dry-run must resolve registry sys `0.0.2` before the safe upload. After both uploads, verify registry metadata, archives, docs.rs, licenses, and a clean downstream build. Create a tag and GitHub release only after separate authorization and only for the exact published commit.

### Retry or verify the safe crate

A safe upload retry is allowed only for the same independently approved archive bytes. Obtain the approved hash externally; never copy a dirty-candidate hash into this document or derive the expected value from a rebuilt archive.

```bash
set -euo pipefail
: "${VLLM_CPP_SAFE_ARCHIVE_SHA256:?set this to the approved safe archive SHA-256}"
if [[ ! $VLLM_CPP_SAFE_ARCHIVE_SHA256 =~ ^[0-9a-f]{64}$ ]]; then
echo 'VLLM_CPP_SAFE_ARCHIVE_SHA256 must be exactly 64 lowercase hexadecimal characters' >&2
exit 1
fi
safe_archive=target/package/vllm-cpp-0.0.2.crate
actual_safe_sha256=$(sha256sum "$safe_archive" | awk '{print $1}')
if [[ $actual_safe_sha256 != "$VLLM_CPP_SAFE_ARCHIVE_SHA256" ]]; then
echo 'safe archive differs from the approved bytes; prepare a new coordinated version' >&2
exit 1
fi
```

Rerun the registry helper after this check. Retry only when `sys_state=accepted` and `safe_state=absent`, and only after separate upload authorization. `ambiguous` means stop. If `safe_state=accepted`, do not upload; instead verify the accepted archive against the same approved hash before post-publication checks:

```bash
set -euo pipefail
accepted_safe=$(mktemp)
trap 'rm -f "$accepted_safe"' EXIT HUP INT TERM
curl --fail --silent --show-error --location --connect-timeout 10 --max-time 60 \
--retry 0 --output "$accepted_safe" -- \
'https://crates.io/api/v1/crates/vllm-cpp/0.0.2/download'
printf '%s %s\n' "$VLLM_CPP_SAFE_ARCHIVE_SHA256" "$accepted_safe" \

Cargo publish uses existing target/package archive or rebuilds cargo package official documentation

💡 Result:

Yes, the cargo publish command performs a full rebuild of the package from scratch [1]. When you run cargo publish, it invokes the same packaging process used by cargo package, which specifically rebuilds the package to ensure it can be built from a clean, pristine state [1]. This process includes several verification steps, such as: 1. Performing verification checks on the package [2]. 2. Rewriting and normalizing the Cargo.toml file [1]. 3. Compressing the source code into a.crate file [2][1]. 4. Extracting the.crate file into a temporary directory and verifying that it compiles [2]. Because cargo package (and by extension cargo publish) builds from scratch to guarantee integrity, it does not rely on existing target/package archives [1]. If you want to verify the contents of what will be published without actually uploading, you can use cargo publish --dry-run (which is equivalent to running cargo package), and then inspect the resulting.crate file in the target/package directory [2][1].

Citations:

Bind the approved hash to the archive that Cargo uploads.

The check at line 174 reads the default target/package archive, but cargo publish -p vllm-cpp --locked packages the workspace again and does not upload that pre-existing file. The check can pass while Cargo uploads different bytes. Verify the downloaded registry archive against VLLM_CPP_SAFE_ARCHIVE_SHA256 after every safe upload.

VLLM_CPP_SAFE_ARCHIVE_SHA256 so the approved hash is verified against the
archive downloaded from the registry after every safe cargo publish, rather than
only against the pre-existing target/package archive. Preserve the retry gating
and stop conditions, and perform the same registry-download verification for the
accepted-safe path.

```

A registry archive mismatch or any need to change the safe bytes requires a new coordinated version; never reuse `0.0.2` for different bytes.

## Abort and recovery

- Before upload, abort on any mismatch, failed gate, unexpected file, dirty state, changed lockfile, native identity/ABI/export drift, inaccurate support statement, or unavailable version. Fix it in a separately reviewed commit and restart.
