Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change allows qualified systems with unavailable memory telemetry to continue onboarding, but malformed GPU index, identity, or memory values may still cause incorrect preflight decisions and allow setup to proceed when validation should fail. Merge should wait for these validation issues to be fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

515-531: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winReject malformed GPU identity and memory text before numeric parsing.
The strict index check does not make the remaining telemetry fail closed. UUID validation runs only in the paired
[N/A]branch, so an ordinary row with a malformed UUID remains selectable.Number()also accepts values such as1e3, and an empty free-memory field becomes0.Validate the UUID and both numeric memory fields as decimal text before calling
Number. Add parser cases for malformed UUIDs and malformed or blank numeric memory fields.Proposed fix

The numeric telemetry path still accepts malformed GPU identity and numeric text in src/lib/inference/vllm.ts:515-524. UUID validation applies only to paired [N/A] fields. Number() also accepts exponent-form values and converts an empty free-memory field to zero. A malformed row can therefore become the selected device and pass the memory preflight. Validate the UUID for every row. Require decimal text for both numeric memory fields before conversion, while preserving the range checks and paired [N/A] handling. Add parser cases for malformed UUID, exponent-form memory, and blank memory fields.

Validation evidence for commit e28f3f88e943ba91e623bd91f8b3c89f3f4893ee:
- Focused CLI Vitest:
src/lib/inference/vllm-compute-capability.test.ts— 31 tests passed. npm run typecheck:clipassed.npm run checks:repositorypassed.- Oxfmt and Oxlint passed for the three changed files.
- Pre-commit hooks, commitlint, and pre-push CLI TypeScript hooks passed.
- GitHub reports this commit verified, and DCO passes.
- The review thread is resolved; complete thread pagination reports 1 total and 0 unresolved.
The earlier changes-requested review targeted 8b3b01be9a and is dismissed because this commit addresses that defect. This comment is neutral. Exact-commit automation is incomplete: Advisor synthesis was skipped, CodeRabbit was rate limited, and required checks remain pending or failed. No approval is appropriate until complete exact-commit gates settle.

Summary
Managed vLLM no longer treats unavailable numeric memory fields as a missing or unhealthy GPU on qualified N1x and DGX Spark profiles. When the selected GPU has a valid index and UUID but reports
[N/A]for both total and free memory, onboarding warns that utilization cannot be pre-validated and continues without inferring available memory.Related Issue
