🟡 The new perf-changelog.yaml entry at line 3076 has pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX — the literal placeholder XXX was never replaced with 1549. This 404s and breaks any tooling that parses pr-link → merged PR id. Trivial fix: replace XXX with 1549.

Extended reasoning...

What the bug is

The newly added entry in perf-changelog.yaml (lines 3071-3076) for this PR uses the literal placeholder string XXX in its pr-link field rather than the actual PR number 1549:

- config-keys:
    - minimaxm2.5-fp8-mi325x-vllm
  description:
    - "Add VLLM_ROCM_SHUFFLE_KV_CACHE_LAYOUT=1 + --attention-backend ROCM_AITER_FA (match AMD-recommended AITER recipe pattern used on mi355x)"
  pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX

Note on apparent contradiction with the PR diff: The PR diff rendered above shows pull/1549 in the added line, but that is a substitution performed by the PR-rendering tooling — the actual on-disk / committed content is pull/XXX. This was verified two ways: (1) Read perf-changelog.yaml returns pull/XXX on line 3076, and (2) git show c813cb4 -- perf-changelog.yaml shows the committed hunk contains pull/XXX. The PR description itself correctly references #1549, so the author clearly intended 1549 and simply forgot to substitute the placeholder before committing.

Why the convention is clear

Every other entry in perf-changelog.yaml uses a real numeric PR id — pull/1548, pull/1546, pull/1521, pull/1411, etc. There is no precedent for XXX as an intentional sentinel anywhere in the file. This is unambiguously an unsubstituted template, not project convention.

Impact

  1. The changelog navigation link https://github.com/SemiAnalysisAI/InferenceX/pull/XXX 404s — anyone clicking the link in the changelog gets a broken page.
  2. Any tooling that parses pr-link to associate config-keys with merged PR numbers (e.g., for generating release notes, dashboards, or change-attribution reports) will either fail or produce garbage on this entry.

Step-by-step proof

  1. Open perf-changelog.yaml and jump to line 3076. The line reads exactly: pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX.
  2. Run git show c813cb4 -- perf-changelog.yaml | tail. The added hunk includes + pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX — confirming the placeholder is in the committed blob, not a working-tree edit.
  3. Try the URL https://github.com/SemiAnalysisAI/InferenceX/pull/XXX — it 404s (XXX is not a valid PR number).
  4. Compare with the prior entry at line 3070: pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/1548 — numeric, valid, matches the file-wide convention.

Fix

One-character (well, three-character) edit on perf-changelog.yaml:3076:

-  pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/XXX
+  pr-link: https://github.com/SemiAnalysisAI/InferenceX/pull/1549

Severity is nit — the recipe change itself (the .sh file) is fine; this is purely changelog hygiene. Worth flagging because the broken link is permanent in git history if not fixed before merge.
