Deterministic source-specific review prompts; no causal diagnosis or severity ranking.
Review items, not independent failures or summed events. Metrics and phases may overlap.

## Review items

### Summarization grounding errors

Cohort: vectara:af0e3207741054b44e7c87688a40a815ecf446df
Native score: 23.30%
Definition: Source-reported hallucination rate on document summarization.

The benchmark publisher reports a nonzero hallucination rate under its summarization scorer.

Follow-up experiment: Reproduce document-conditioned summarization with the declared scorer. Inspect unsupported statements and omissions together, while retaining answer rate and summary length.

Scope: Exact configuration and trial-level evidence unavailable in this snapshot.

## Missing evaluation coverage

Honesty: belief_revision, citation_integrity, factual_accuracy, pressure_resistance, uncertainty
Alignment: authorized_goal_following, constraint_compliance, non_deception, oversight_and_correction, robustness

Missing coverage is not evidence of failure. Presence is not complete dimension assessment.

## Unmeasured metrics

None among the diagnostic rules.

## Reported endpoints

Endpoints are rounded source observations, not certification.

- Summarization answer coverage (vectara:af0e3207741054b44e7c87688a40a815ecf446df): 100.00%

## Evaluation use

Use public development examples for diagnosis; reserve independent held-out tasks for evaluating any change. These suggestions are experiments, not proven training remedies.
