What

Rewrites the revert_scoring_accuracy LLM judge rubric in the payload-analysis eval so a correct result is never docked for confidence calibration or analysis polish.

The prior rubric graded on proximity to expected_confidence (e.g. "within 5 points" for a 5, "within 10" for a 4), which penalized a correct verdict for being more confident than the reference value. Being more confident in the right answer is not a defect.

New scale (result-first, threshold-based)

  • 5 — expected candidate scored ≥ 85 and linked to the correct failing jobs, or no revert proposed when none is expected
  • 4 — correct candidate scored 70–84, or correct result with a factual failing-job linkage error
  • 3 — correct candidate identified but scored below 70
  • 2 — wrong result with some investigation
  • 1 — wrong result with little investigation

expected_confidence is now treated as a reference floor: a correctly-identified candidate scored at or above it (including the 100 cap) gets full credit. Scope is limited to the revert decision (candidate, confidence, failing-job linkage); payload phase, failed-job count, and force_accept are scored by their own dedicated judges.

The rubric is also rewritten in affirmative language and trimmed for concision.

Hi @not-stbenjam. Thanks for your PR.

I'm waiting for a openshift-eng member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Walkthrough

The payload-analysis evaluation removes fixed expected-confidence annotations and CI-configuration issue exceptions. It retains candidate metadata and minimum confidence thresholds. The scoring rubric now evaluates expected-candidate selection, the 85-point threshold, failing-job links, unexpected reverts, evidence, and no-revert outcomes.

Changes

Payload analysis evaluation

Layer / File(s) Summary
Expected candidate annotation updates
plugins/ci/evals/cases/payload-analysis/case-*/annotations.yaml
Expected candidates no longer declare fixed expected_confidence values. Existing candidate metadata remains. Case 006 uses min_confidence: 85 for its first candidate.
Revert validation and scoring rules
plugins/ci/evals/eval-payload-analysis.yaml
The evaluator no longer uses expected_ci_config_issues as allowed revert candidates. The judge removes reference-floor guidance and applies revised 1–5 criteria for candidate selection, the 85-point threshold, failing-job links, unexpected reverts, supporting evidence, and no-revert outcomes.

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

Merge Risk: 🟡 Moderate · up to 28997

The updated CI scoring rubric may incorrectly reject or downgrade valid results when a case expects multiple candidates with different confidence thresholds, causing misleading evaluation outcomes. Merge should wait until each candidate is evaluated against its intended threshold.

openshift/release#76852 lived in a separate expected_ci_config_issues
bucket that no judge required, so a run could miss that revert and still
score full marks on case-001. Fold it into expected_candidates and drop
the special bucket so every revert is required uniformly.

Replace the confidence-proximity scale (which docked a correct verdict
for scoring above expected_confidence) with a threshold-based 5-to-1
scale: full credit when every expected candidate is scored >= 85 and
linked, or no revert when none is expected. expected_confidence becomes
a reference floor rather than a target.

The revert_scoring_accuracy rubric is threshold-based (a candidate at or
above 85 is correct), which conflicted with the expected_confidence
reference-floor text and made the field redundant — no judge reads it.
Remove the calibration paragraph and the expected_confidence field from
all payload-analysis cases and the schema note.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Every expected_candidate is now a revert, so each min_confidence was just
the revert threshold copied per candidate. Hardcode the 85 threshold in
expected_candidates_found and remove the field from all payload-analysis
cases and the schema note. Also drop case-006's below-threshold "secondary
candidate" (#8138) so expected_candidates holds only actual reverts.

693-717: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Do not apply the 85-point requirement to every expected candidate.

expected_candidates still defines a per-candidate min_confidence. plugins/ci/evals/cases/payload-analysis/case-006/annotations.yaml contains one expected candidate with min_confidence: 40 and another with min_confidence: 85. Requiring every expected candidate to score at least 85 can reject a valid low-confidence candidate or force the evaluator to treat it as a revert. Keep 85 as the primary revert threshold, but evaluate additional candidates against their own min_confidence or exclude them explicitly from this rule.

State the asymmetry plainly so the judge can't read a low-confidence
extra candidate as a false revert: >= 85 is a proposed revert, below 85
is an ignored maybe. Expected reverts must reach 85; an extra candidate
is a false revert only at 85 or above.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bump the ci plugin version and sync marketplace/docs to satisfy the
check-version-bump gate. Also drop the non-applicable component field
from the openshift/release revert candidate in case-001 (component is
documentation only and not consumed by any judge).
