## Summary

A structural condition where nodes, edges, dependencies, decisions, or effects concentrate sharply within a localized region beyond declared thresholds.

## Primary Lenses

- LEN-0140 — Compression Lens
  - URL: /workbench/lenses/compression-lens/
  - Summary: Reduces structural graphs into stable minimal representations for comparison, redundancy detection, and diffing.
- 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.

## Secondary Lenses

- LEN-0190 — Escalation Gradient Lens
  - URL: /workbench/lenses/escalation-gradient-lens/
  - Summary: Measures structural growth or intensification across sequential executions, states, or transitions.

## Primary Issue Matches

- ISS-0010 — Answer Has Too Many Paths
  - URL: /workbench/issues/answer-has-too-many-paths/
  - Summary: The answer presents too many possible paths, interpretations, options, or next steps without enough structure to choose among them.
- ISS-0104 — One Prompt Carries Too Many Meanings
  - URL: /workbench/issues/one-prompt-carries-too-many-meanings/
  - Summary: A single prompt carries too many meanings, goals, roles, constraints, or implied tasks for the AI to interpret consistently.
- ISS-0105 — Review Queue Becomes Bottleneck
  - URL: /workbench/issues/review-queue-becomes-bottleneck/
  - Summary: A review queue, approval path, or validation stage accumulates too much work and begins blocking the workflow.
- ISS-0107 — Single Field Carries Too Many Obligations
  - URL: /workbench/issues/single-field-carries-too-many-obligations/
  - Summary: One field, label, score, status, or structured value is expected to carry too many meanings, decisions, or workflow obligations.
- ISS-0103 — Single Step Carries Too Many Decisions
  - URL: /workbench/issues/single-step-carries-too-many-decisions/
  - Summary: One prompt, workflow step, review stage, or agent action carries too many decisions for the system or user to evaluate cleanly.

## Supporting Issue Matches

- ISS-0027 — Duplicate Fields With Same Meaning
  - URL: /workbench/issues/duplicate-fields-with-same-meaning/
  - Summary: The AI returns multiple fields, labels, sections, or structured elements that carry the same meaning and create ambiguity about which one should be used.
- ISS-0066 — Duplicate Output Sections
  - URL: /workbench/issues/duplicate-output-sections/
  - Summary: The AI repeats sections, headings, blocks, or output areas in a way that creates redundancy, confusion, or downstream handling problems.
- ISS-0070 — Multiple Policies Say the Same Thing
  - URL: /workbench/issues/multiple-policies-say-the-same-thing/
  - Summary: Multiple policies, rules, or guidance documents express the same requirement, creating redundancy and uncertainty about which one governs.
- ISS-0060 — Output Exceeds Length Limit
  - URL: /workbench/issues/output-exceeds-length-limit/
  - Summary: The AI output exceeds a declared length, token, word, character, section, field, or size limit.
- ISS-0071 — Prompt Has Too Many Valid Interpretations
  - URL: /workbench/issues/prompt-has-too-many-valid-interpretations/
  - Summary: The prompt allows too many reasonable interpretations, causing the AI to choose among valid paths without enough guidance.
- ISS-0068 — Repeated Constraints Create Confusion
  - URL: /workbench/issues/repeated-constraints-create-confusion/
  - Summary: Repeated constraints, instructions, limits, or exclusions make the task harder to interpret instead of clearer.
- ISS-0062 — Retrieval Exceeds Evidence Limit
  - URL: /workbench/issues/retrieval-exceeds-evidence-limit/
  - Summary: The AI retrieves, uses, cites, or considers more evidence than the task permits or more than the review surface can support.
- ISS-0067 — Same Rule Declared in Multiple Places
  - URL: /workbench/issues/same-rule-declared-in-multiple-places/
  - Summary: The same rule, constraint, instruction, or policy appears in multiple places, creating redundancy and possible drift.
- ISS-0069 — Same Workflow Check Happens Twice
  - URL: /workbench/issues/same-workflow-check-happens-twice/
  - Summary: The same review, validation, approval, routing, or safety check occurs more than once in the workflow without a clear reason.
