[Klaud Cold] Signoff verifier: Check 3 recipe link is N/A for disagg/multi-node PRs

[functionstackx]

Summary

• Scopes the sign-off verifier's Check 3 (recipe linked + complete) to single-node recipes only: the official upstream recipe sources (vLLM recipes, SGLang cookbook) publish single-node serve commands, so disaggregated / multi-node submissions (dynamo-trt/dynamo-sglang, ATOM/ATOMesh, sglang-disagg, vLLM disagg, benchmarks/multi_node/** incl. srt-slurm-recipes/**, master-config entries with multinode: true/disagg: true) now report ➖ N/A instead of ❌ FAIL.
• A sign-off note like "this is a disagg submission, no recipe update required" is treated as a legitimate statement of that fact.
• Mixed PRs (single-node + multi-node changes) still get the recipe-link requirement applied to the single-node portion.
• Fixes false rejections like Add DSV4 FP4 B200 Dynamo-vLLM point-specific disagg recipes #1963 (comment).

Test plan

• YAML validated locally.
• After merge: throwaway disagg-only test PR + sign-off with no recipe link → expect Check 3 = N/A (not FAIL).

LGTM — prompt-only tweak to scope Check 3 to single-node recipes; no workflow logic or permission changes.

Extended reasoning...

Overview

This PR modifies only the Claude prompt text inside .github/workflows/codeowner-signoff-verify.yml. Specifically, it updates the description of Check 3 (recipe linked + complete) to explicitly scope the requirement to single-node recipes and report disaggregated / multi-node submissions as N/A rather than FAIL. It also updates the header comment block accordingly.

Security risks

None. The change touches only natural-language instructions given to Claude within the workflow; it does not alter permissions, secrets handling, the trusted-branch checkout policy, the MCP config, the concurrency group, or any of the surrounding shell/JavaScript logic. The security-critical property of this workflow — that it never checks out untrusted PR head code — is preserved.

Level of scrutiny

Low. This is a prompt-clarification change to a workflow that gates merges, but the modification narrows a false-positive failure mode (disagg/multi-node PRs getting FAIL on Check 3 despite having no upstream recipe source) and does not weaken any of the eight substantive gates. The listed disagg indicators (multinode: true, disagg: true, dynamo-trt/dynamo-sglang, ATOM/ATOMesh, sglang-disagg, benchmarks/multi_node/**, srt-slurm-recipes/**) match established framework/config conventions in the repo.

Other factors

Bug hunting system found no bugs. Mixed PRs still get single-node recipe enforcement per the added explicit instruction. The change is small, self-contained, and cleanly reversible.
