fix(inference): update Muse Glimmer vLLM image for revision handling

[prekshivyas]

Summary

Replace the DGX Spark Muse Glimmer vLLM ARM64 digest with an immutable official image that preserves the requested Hugging Face model revision across vLLM engine spawning. The previous image fell back to main and surfaced a misleading sentencepiece/tiktoken tokenizer error even though both packages were installed.

Related Issue

Fixes #9601.

Changes

• Pin vllm/vllm-openai@sha256:b0e84e5f2b00a7268e4fdda332790ebd4bfb166b64757e166914753afaeee965, built from vLLM commit 5a4c8d99242e9e069b604d0e9b969e77f7dd501d.
• Record the exact image manifest, configuration, source ancestry, runtime dependency versions, and revision-serialization evidence.
• Protect the image, huggingface_hub 1.28.0, and post-pickle revision with catalog and provenance tests.
• Update the vLLM setup documentation with the qualified digest and dependency fix.

Type of Change

• Code change (feature, bug fix, or refactor)
• Code change with doc updates
• Doc only (prose changes, no code sample modifications)

DGX Spark Hardware Evidence

Validated on a physical ARM64 DGX Spark with an NVIDIA GB10 using model Inferact/Muse-Glimmer-30B-NVFP4-W4A4 at revision d35cb79050f419c457611b1cee5c5d15b176f285.

• reproduced the old image failure with vllm/vllm-openai@sha256:677afd5bf3b4bb9881f91e107af7098f8410726b4c05b25cb4a815900b398204
• imported sentencepiece 0.2.2, tiktoken 0.14.0, and huggingface_hub 1.28.0 from the replacement image
• verified that the resolved revision survives a pickle round trip
• started the full recipe-equivalent vLLM server from cold cache without a usable refs/main
• verified authenticated /v1/models, /tokenize, chat reasoning, and structured Muse Glimmer tool calling
• observed zero vLLM container restarts

Verification

• PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub
• Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
• Targeted behavior tests pass for the current change set, or tests are marked not applicable above — 115 focused CLI tests, 18 provenance/compiler integration tests, and 32 growth guardrails passed.
• Applicable broad gate passed — Not applicable to this image-pin/provenance-only change. npm run test:changed selected six unrelated suites with 18 failures that reproduce identically at base commit dbf48bae9d35beda8d781205a46e881d6f8f900a.
• Quality Gates section completed with required justifications or waivers — sensitive-path maintainer review remains pending.
• No secrets, API keys, or credentials committed
• npm run docs builds without warnings (doc changes only) — npm run docs passed with the two existing Fern warnings.
• Doc pages follow the style guide (doc changes only)
• New doc pages include SPDX header and frontmatter (new pages only)

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 20c56

This change updates the production vLLM image and runtime dependencies for Muse Glimmer. It is not merge-ready until the pending sensitive-path maintainer review is completed or explicitly waived, and the installation-path runtime-resolution test concern is addressed or accepted.

134-138: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exercise architecture normalization through the installation path.

Line 137 only checks the number of checks returned by vllmInstallTestReadiness. It does not execute readiness or verify the resolved architecture. A regression that leaves architecture undefined can still pass this test.

Call installVllm with the profile that omits architecture, then assert an observable runtime-selection or install outcome.

As per path instructions, “Prefer observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions.”

Requesting changes on commit under review 164747a:

• test/muse-glimmer-vllm-image-provenance.test.ts:37-60: the parameterized tests mutate the checked-in provenance record and only assert that the verifier throws. They never verify the unmodified record or bind it to the selected recipe and resolved runtime. If the checked-in record already drifts from the expected provenance, every tamper case still passes. Add a positive assertion for the unmodified record and the recipe/resolved-runtime image and size.

The immutable manifest, ARM64 config, vLLM ancestry, and focused runtime, catalog, documentation, build, and type checks otherwise match the PR claims.

[apurvvkumaria]

Reviewed commit 164747a. I found no critical blocker. The immutable image digest, provenance record, ARM64 runtime selection, catalog wiring, documentation, and fail-closed configuration are consistent. The remaining positive-test-strength suggestion does not demonstrate a product defect.

[senthilr-nv]

Approved on commit under review 20c567d.

The positive contract now verifies the checked-in provenance and binds it to the selected recipe and resolved runtime image and size. The source-shape check, 23 focused integration tests, test-title check, commit hooks, and pre-push type check passed. GitHub reports the repair commit as Verified. Product scope and architecture are unchanged.
