## Summary

An evaluation rubric, grading standard, or review checklist leaves part of the required evaluation space uncovered.

## Category

- CAT-0120 — Coverage & Guidance
  - URL: /workbench/categories/coverage-and-guidance/
  - Summary: Problems where prompts, rubrics, diagnostics, fallback rules, examples, requirements, or relationship maps are incomplete, underspecified, or missing needed guidance.

## Primary Pattern

- PAT-0280 — Density Vacuum
  - URL: /workbench/patterns/density-vacuum/
  - Summary: A structural condition where a region expected to contain sufficient nodes, edges, coverage, or relationships falls below declared density thresholds.

## Declared Patterns

- PAT-0280 — Density Vacuum
  - URL: /workbench/patterns/density-vacuum/
  - Summary: A structural condition where a region expected to contain sufficient nodes, edges, coverage, or relationships falls below declared density thresholds.
- PAT-0130 — Incomplete Declaration
  - URL: /workbench/patterns/incomplete-declaration/
  - Summary: A structural condition where an element is declared but required attributes, dependencies, or linked definitions are missing.
- PAT-0170 — Constraints Underspecified
  - URL: /workbench/patterns/constraints-underspecified/
  - Summary: A structural condition where declared constraints are insufficient to eliminate ambiguity or multiple admissible states.

## Derived Primary Lenses

- LEN-0100 — Absence Lens
  - URL: /workbench/lenses/absence-lens/
  - Summary: Detects structurally required elements that are missing from the observed structure.
- LEN-0140 — Compression Lens
  - URL: /workbench/lenses/compression-lens/
  - Summary: Reduces structural graphs into stable minimal representations for comparison, redundancy detection, and diffing.
- LEN-0160 — Constraint Sufficiency Lens
  - URL: /workbench/lenses/constraint-sufficiency-lens/
  - Summary: Evaluates whether declared constraints are sufficient to eliminate structural degrees of freedom.

## Derived Secondary Lenses

- LEN-0180 — Determinism Lens
  - URL: /workbench/lenses/determinism-lens/
  - Summary: Evaluates whether identical structural inputs produce equivalent structural outputs across repeated executions.
- LEN-0200 — Interface Contract Lens
  - URL: /workbench/lenses/interface-contract-lens/
  - Summary: Compares declared interface structure to observed runtime structure to detect contract deviations.
- LEN-0290 — Variance / Entropy Lens
  - URL: /workbench/lenses/variance-entropy-lens/
  - Summary: Measures structural variability across repeated or comparable evaluations and identifies divergence beyond expected bounds.
