🟡 The new perf-changelog entry for qwen3.5-fp8-b200-sglang uses a placeholder PR link (pull/XXX) instead of the actual PR number. This should be https://github.com/SemiAnalysisAI/InferenceX/pull/918.

Extended reasoning...

What the bug is

The new entry added at the end of perf-changelog.yaml (line 979) has pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX instead of the actual PR number 918. This is a copy-paste artifact where the author forgot to fill in the placeholder before submitting.

How it manifests

Any tooling or documentation that parses perf-changelog.yaml to generate changelogs, link back to PRs, or track configuration history will produce a broken link for this entry. The URL pull/XXX does not resolve to a valid GitHub pull request.

Step-by-step proof

  1. The PR diff adds a new block to perf-changelog.yaml starting with config-keys: [qwen3.5-fp8-b200-sglang].
  2. The last line of this new block is pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX.
  3. The PR number for this change is 918 (visible in the PR metadata: <pr number="918">).
  4. Therefore the correct value should be pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/918.

Why existing code does not prevent it

There is no CI validation that checks whether pr-link values in perf-changelog.yaml contain valid PR numbers. The file already has a few other pre-existing pull/XXX placeholders from previous PRs that were merged without being corrected.

Impact

Low — this is a documentation/metadata issue. The benchmark configs and scripts themselves are correct. The only impact is a broken traceability link in the changelog.

Fix

Replace pull/XXX with pull/918 on line 979 of perf-changelog.yaml.
