Rule-17 review at 283c17c: approve. The workflow does what it says, and the three suggestions below are for you to take or leave.
Checked:
- 3 files, no Rust.
- The ref file holds bellwether main's 64f0525d, which is #29's squash.
- The pin is validated as 40 hex digits before use.
- Without the token, the job is a notice and a pass; on this head it passed that way. Forks get the same, and the push to main runs the tests.
persist-credentials: falseon the bellwether checkout.- The concurrency group matches the new
cancel-pr-workflows.ymlentry.
What the three tests exercise, against the trigger list:
- the tokenizer test:
llm_tokenizeronly (crates/tokenizer/**); - the gateway render test:
openai_protocol(ChatCompletionRequest,Normalizable, validation;crates/protocols/**),llm_tokenizer, andsmg::routers::grpc::utils::process_chat_messages(model_gateway/src/routers/grpc/**); - the Symphony test:
smg-symphony, which depends only onopenai-protocol.
So the list covers them. Two small gaps:
Cargo.tomlmatches the root file only.model_gateway/Cargo.tomlholds the render test's dev-dependency (toml) and the gateway's features, and a features-only change there does not touchCargo.lock. Suggest**/Cargo.toml, ormodel_gateway/Cargo.tomladded. Likewise, consider.github/actions/setup-rust/**, since the job uses that composite action.process_chat_messagesimports two modules outsiderouters/grpc:crate::routers::common::sseandcrate::routers::error(chat_utils.rs:31-35). Neither touches rendering, so leaving them out is defensible. I mention it only so the omission is a choice.
Cache key: take this one before the pin starts moving. The tokenizer files depend only on each manifest's model and revision. Keying the cache on the bellwether commit stores a new full copy at every pin move, even when no manifest changed; most moves will re-record sets at the same revisions. With "all models" (89 cached today, about 1 to 2 GB of tokenizer files), a handful of moves fills the repository's 10 GB cache, and LRU eviction then takes sccache's entries too. A key on the manifests does not move when only the sets do:
key: bellwether-tokenizers-${{ hashFiles('.bellwether/fixtures/*/manifest.toml') }}
restore-keys: |
bellwether-tokenizers-The restore-keys line keeps the partial reuse you have now.
Notes for later, not for this PR:
- Compressed sets. Once bellwether #31 lands, benchmark sets are
.jsonl.zstin Git LFS, and the three tests read*.jsonlonly. They would skip those sets without a word. The job will then needbellwether unpack(uv, git-lfs, the same token for the LFS objects), withBELLWETHER_FIXTURESpointed at the unpacked tree, and the tests checking what they read againstsets.toml. - Downloads. With no Hugging Face token, a cold cache downloads anonymously. Across ~90 models that may meet rate limits. A read token, passed as
HF_TOKENto the tests' downloader, would avoid it if the downloader sends one.

Re-approval at 0f07859. The three suggestions are in, and the diff from 283c17c holds only them:
model_gateway/Cargo.tomland.github/actions/setup-rust/**are in bothpathslists;- the cache key is the manifests' hash.
On the two open bot threads:
-
:31(model_gateway/Cargo.tomlmissing): this commit answers it, so it can be resolved with a pointer to 0f07859. -
:125(the key depends on more than the manifests): this one is right, and it follows from my suggestion. Which files each test fetches is code:tokenizer_dir's list inmodel_gateway/tests/bellwether_render_parity.rs:421-427, and the tokenizer crate's test once #2817 lands. Suppose a pull request addsgeneration_config.jsonto that list:- the next run gets an exact hit and restores the old entry;
- the test downloads the new file for every model;
actions/cachedoes not save after an exact hit, so the entry never gains the file;- every later run downloads it again, until a manifest changes.
Hashing the test files with the manifests closes it, and the key still does not move when only the sets do:
key: bellwether-tokenizers-${{ hashFiles('.bellwether/fixtures/*/manifest.toml', 'model_gateway/tests/bellwether_*.rs', 'crates/tokenizer/tests/bellwether_*.rs') }}Approving now. The key change is small enough to take on sight.

The tests named bellwether_* skip unless BELLWETHER_FIXTURES is set, and no workflow sets it, so CI compiles them and runs nothing. A new workflow checks out smg-project/bellwether at the commit pinned in .github/versions/bellwether.ref and runs them whenever the protocol crate, the tokenizer crate, the gRPC router, Symphony or the dependencies change, on pull requests and on pushes to main.

The tokenizer files depend on each manifest's model and revision, not on the bellwether commit, so a key made of the commit would store a full copy at every move of the pin. The gateway's own Cargo.toml (the test's features and dev-dependencies) and the setup-rust action the job uses now start a run too.

…e tests The pin was 64f0525, before bellwether #31 gave each model a sets.toml and stored benchmark sets compressed, and before #50 pinned the render libraries to the vLLM image's. It moves to c3c72ec, bellwether's main with both. The job now installs uv and runs bellwether's own `unpack` on the checkout, and the tests read the plain tree it writes: each model's manifest, its table of sets, and the sets as JSON Lines. Every set pinned today is plain; once a compressed set is pinned, the unpack step fetches it from bellwether's LFS store and needs the token there, which the workflow comment says.

Re-review at 8a9aa1f: approve. The two new commits do what they say, and the job's pipeline runs end to end at the new pin. One thing to do before merging: create the BELLWETHER_READ_TOKEN secret. Without it, this pull request's own fixture-tests fails, as designed, and so would the push to main.
What I ran
The job's steps, locally, at 8a9aa1f with bellwether at c3c72ec, using a dedicated target directory:
uv run --project .bellwether bellwether unpack --fixtures .bellwether/fixtures --out .bellwether/fixtures-plain: exit 0. It wrote the plain tree:deepseek-r1/{manifest.toml,sets.toml,render/common.jsonl}andqwen3-8b/{manifest.toml,sets.toml,render/common.jsonl,parse/common.jsonl}. Every set pinned at c3c72ec is plain (no.jsonl.zstunderfixtures/), so the step needs no LFS today, as the workflow comment says.cargo +1.98.0 test -p llm-tokenizer -p smg -p smg-symphony --test 'bellwether_*' -- --nocapture, withBELLWETHER_FIXTURESpointing at that plain tree: exit 0.- The gateway's render parity test passes 1 of 1. Each case that differs cites its known issue: #2779 (continued turn), #2780 (
add_generation_prompt), #2783 (R1 and object arguments), and bellwether#13 (empty user content). - Symphony's token-plan and parse-fixture tests pass 2 of 2.

The two commits
- 7d86538:
persist-credentials: falseon the first checkout.- A run without the token fails, except a pull request from a fork or one Dependabot opened. Both cases are spelled correctly:
head.repo.full_name != github.repository, anduser.login == 'dependabot[bot]'. - The cache key hashes the tests that choose which files to fetch.
scripts/ci_install_rust.shis a trigger.
- 8a9aa1f: the pin moves to c3c72ec (#31's storage form and #50's pins), with bellwether's own
unpackbefore the tests. - This PR's own run (37536831639): it stops at "Read the pinned bellwether commit" with
::error::BELLWETHER_READ_TOKEN is not set…and exit 1. That is the new rule doing its job.
On the two open threads
--locked: agreed. A staleuv.lockat a pinned commit should fail rather than resolve fresh versions in CI.--no-devchanges nothing here: bellwether's dev tools are an extra ([project.optional-dependencies] dev), not a dependency group, anduv runinstalls neither without asking. Installing the 36 packages took 0.3 s from a warm cache.- Hashing
fixtures-plain/*/manifest.toml: agreed. It ties the key to what the tests read.
Rule 17
- Commits: two new ones, each signed off by Simo Lin, with no AI trailer.
- Scope:
.github/only: the workflow andversions/bellwether.ref.
…izer cache on the unpacked manifests Two review nits. `uv run` without `--locked` would resolve anew against PyPI when the pinned commit's lock file is out of date, and run the unpack on versions bellwether never locked; `--locked` makes that a failure instead. The tokenizer cache key hashed the manifests in the source tree while the tests read the unpacked copy; it hashes the copy now, so the key cannot stop depending on the manifests if the source layout moves.

Description
Problem
The tests that read bellwether's fixtures never run in CI.
model_gateway/tests/bellwether_render_parity.rs(#2782),crates/symphony/tests/bellwether_parse_fixtures.rsand the tokenizer test of #2817 all skip unlessBELLWETHER_FIXTURESis set, and no workflow sets it. A change to the protocol crate, the tokenizer crate or the gRPC router can therefore change the prompt tokens smg sends, or the text it decodes, and merge with every check green.Run by hand today across 89 models (bellwether#39), the same tests found six models whose tokenizer does not load in smg and three other defects (#2818 to #2821). None of them would have been caught by CI.
Solution
A workflow,
Bellwether Fixtures, that checks out smg-project/bellwether at a pinned commit and runs every test target namedbellwether_*inllm-tokenizer,smgandsmg-symphony.crates/protocols/**,crates/tokenizer/**,crates/symphony/**,model_gateway/src/routers/grpc/**, the gateway'sbellwether_*test files and itsCargo.toml, the rootCargo.toml,Cargo.lock, the pinned commit, thesetup-rustaction and its install script, or the workflow itself. It can also be started by hand..github/versions/bellwether.ref, the same form astokenspeed.ref. Moving to newer fixtures is a one-line pull request, and that pull request runs against the new commit. It starts at bellwether main, 64f0525d.cargo test -p llm-tokenizer -p smg -p smg-symphony --test 'bellwether_*'. The three targets then build with the same features, which the tokenizer test's download of tokenizer files needs (alone,llm-tokenizer'sreqwesthas no TLS backend), and a new test file with that name prefix is picked up without touching the workflow.BELLWETHER_READ_TOKENsecret with read access to that repository's contents, passed toactions/checkoutwithpersist-credentials: false. A pull request from a fork or from Dependabot is not given the repository's secrets: there the job prints a notice and passes without running the tests, and the push to main after the merge runs them. Any other run without the token fails, so a secret that is missing or has expired cannot pass for tests that ran.It is a separate workflow and not a step in
unit-testsfor three reasons. Its triggers are exactly the code these tests judge. It reports as its own check. And the cost that comes with larger fixtures (tokenizer files for every model, minutes of test time) stays out of the 30-minute test step.Needs the repository owner, and is not to merge before: a
BELLWETHER_READ_TOKENsecret on this repository (and the same value as a Dependabot secret, if dependency updates should run these tests before they merge). Until it exists this pull request's own run fails, which is the true state. Once it exists I will re-run the job, so the first real run is seen here and not on main.Changes
.github/workflows/bellwether-fixtures.yml: the workflow..github/versions/bellwether.ref: the pinned bellwether commit, c3c72ec (bellwether's main: Simplify HTTP tokenize handlers to use registry.resolve() #31'ssets.tomland compressed benchmark sets, Consolidate workspace dependencies across all crates #50's render-library pins).unpackon the checkout; the tests read the plain tree it writes. Every set pinned today is plain, so no LFS object is fetched; once a compressed set is pinned, the unpack step needs the token for bellwether's LFS store, which the workflow comment says..github/workflows/cancel-pr-workflows.yml: the new workflow's concurrency group, so closing a pull request cancels its run.Test Plan
uv run --project <bellwether at c3c72ec> bellwether unpack --fixtures <its fixtures> --out <scratch>, from another directory as the job runs it:3 plain fixture sets, the two models' manifests,sets.tomland plain sets in the scratch tree.The command the workflow runs, locally on this branch's base plus test(tokenizer): check encode and incremental decode against bellwether's fixtures #2817's test, with
BELLWETHER_FIXTURESat bellwether 64f0525d'sfixtures/(the plain sets are the same files at c3c72ec, apart from the provenance's transformers version):On main without test(tokenizer): check encode and incremental decode against bellwether's fixtures #2817 the pattern matches the other two targets.
actionlinton both workflow files: no findings.pre-commiton the three files: passes (check yaml,codespelland the rest).Not yet proven: the workflow's own steps on a runner (the second checkout with the token, the tokenizer download on a cold cache). Without the secret this pull request's run stops at the first step with the error that names it; the first commit's run took the then no-secret path and passed in 7 s. The re-run after the secret exists is the real test, and I will post its result here.
No Rust file changes, so the two boxes below are not ticked.
