Canonical 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.

## Category

- CAT-0140 — Duplication & Overload
  - URL: /workbench/categories/duplication-and-overload/
  - Summary: Problems where fields, sections, rules, checks, prompts, workflow steps, or review queues become duplicated, overloaded, bottlenecked, or carry too many meanings.

## Primary Pattern

- PAT-0370 — Redundant Declaration
  - URL: /workbench/patterns/redundant-declaration/
  - Summary: A structural condition where multiple declarations produce equivalent structural effect without semantic differentiation.

## Declared Patterns

- PAT-0370 — Redundant Declaration
  - URL: /workbench/patterns/redundant-declaration/
  - Summary: A structural condition where multiple declarations produce equivalent structural effect without semantic differentiation.
- PAT-0190 — Contract Drift
  - URL: /workbench/patterns/contract-drift/
  - Summary: A structural condition where a declared contract changes but connected structures, implementations, consumers, or expectations do not update in sync.
- PAT-0270 — Density Spike
  - URL: /workbench/patterns/density-spike/
  - Summary: A structural condition where nodes, edges, dependencies, decisions, or effects concentrate sharply within a localized region beyond declared thresholds.

## Derived 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-0150 — Conflict Lens
  - URL: /workbench/lenses/conflict-lens/
  - Summary: Detects mutually incompatible constraints, claims, states, or declarations that cannot be simultaneously satisfied.
- LEN-0170 — Convergence Lens
  - URL: /workbench/lenses/convergence-lens/
  - Summary: Compares parallel structural systems to determine whether they align under shared authority.
- LEN-0230 — Normalization Lens
  - URL: /workbench/lenses/normalization-lens/
  - Summary: Transforms structurally equivalent variants into a canonical form to prevent false divergence.
- LEN-0270 — Reconciliation Lens
  - URL: /workbench/lenses/reconciliation-lens/
  - Summary: Evaluates whether structural changes align with declared authority updates, version changes, or reconciliation rules.
- 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.

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