## Summary

Expectations from a prior model, prompt, schema, tool, or workflow survive a migration and continue shaping review or downstream handling after they should be replaced.

## Category

- CAT-0080 — Changes & Versions
  - URL: /workbench/categories/changes-and-versions/
  - Summary: Problems where model behavior, prompts, contracts, schemas, outputs, references, rubrics, or expectations change without the surrounding workflow updating correctly.

## Primary Pattern

- 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.

## Declared Patterns

- 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-0350 — Persistence Instability
  - URL: /workbench/patterns/persistence-instability/
  - Summary: A structural condition where persisted state cannot be stored and restored into an equivalent structure without alteration.
- PAT-0370 — Redundant Declaration
  - URL: /workbench/patterns/redundant-declaration/
  - Summary: A structural condition where multiple declarations produce equivalent structural effect without semantic differentiation.

## Derived Primary Lenses

- 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-0280 — Reference Stability Lens
  - URL: /workbench/lenses/reference-stability-lens/
  - Summary: Evaluates whether structural references, identifiers, nodes, and edges remain consistent across execution cycles or comparable states.

## Derived Secondary 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-0180 — Determinism Lens
  - URL: /workbench/lenses/determinism-lens/
  - Summary: Evaluates whether identical structural inputs produce equivalent structural outputs across repeated executions.
