Structural Patterns

Patterns

Canonical structural forms declared by Workbench Issues and connected to analytical Lenses.

PAT-0110

Asymmetric Structure

A structural condition where comparable regions receive unequal rule, constraint, or authority application without a declared differentiation rule.

PAT-0100

Authority Collision

A structural condition where multiple authorities claim governance over the same region without a declared precedence or resolution rule.

PAT-0220

Authority Merge Conflict

A structural condition where multiple authority states are combined over a shared scope without a declared merge, precedence, or reconciliation rule.

PAT-0230

Authority Shadowing

A structural condition where a declared authority is functionally overridden by another authority without an explicit override rule.

PAT-0240

Authority-State Mismatch

A structural condition where observed system state no longer aligns with the declared authority state that is supposed to govern it.

PAT-0140

Boundary Leakage

A structural condition where effects, permissions, state, data, or authority cross a declared boundary without an authorized exception.

PAT-0250

Circular Dependency

A structural condition where two or more elements depend on each other in a closed loop without an independent base condition or declared resolution mechanism.

PAT-0180

Compatibility Violation

A structural condition where a graph, object, behavior, or runtime state exceeds a declared compatibility envelope without an authorized exception.

PAT-0170

Constraints Underspecified

A structural condition where declared constraints are insufficient to eliminate ambiguity or multiple admissible states.

PAT-0190

Contract Drift

A structural condition where a declared contract changes but connected structures, implementations, consumers, or expectations do not update in sync.

PAT-0320

Convergence Failure

A structural condition where sequential or parallel states fail to resolve into an equivalent or coherent structure under shared authority and constraints.

PAT-0260

Cross-Layer Escalation

A structural condition where escalation originating in one layer propagates into another authority, boundary, or control layer without explicit authorization.

PAT-0270

Density Spike

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

PAT-0280

Density Vacuum

A structural condition where a region expected to contain sufficient nodes, edges, coverage, or relationships falls below declared density thresholds.

PAT-0290

Divergent Outputs

A structural condition where parallel evaluations under comparable scope and shared authority produce non-equivalent outputs.

PAT-0300

Escalation Growth

A structural condition where impact, authority, scope, or consequence increases across sequential states without a declared limiting mechanism.

PAT-0130

Incomplete Declaration

A structural condition where an element is declared but required attributes, dependencies, or linked definitions are missing.

PAT-0150

Interface Mismatch

A structural condition where observed interface behavior, shape, or exchange differs from the declared interface contract.

PAT-0330

Invariant Breakage

A structural condition where an observed state violates a declared invariant that is supposed to remain true.

PAT-0120

Missing Authority

A structural condition where a region, action, state, or decision path exists without a declared governing authority.

PAT-0210

Non-Deterministic Execution

A structural condition where equivalent inputs and declared constraints produce divergent outputs across executions.

PAT-0310

Orphaned Structure

A structural condition where a node, region, object, state, or declaration exists without linkage to the governing graph or integration pathway.

PAT-0340

Overreach

A structural condition where actions, effects, authority, or modifications extend beyond declared scope without authorization.

PAT-0350

Persistence Instability

A structural condition where persisted state cannot be stored and restored into an equivalent structure without alteration.

PAT-0360

Propagation Amplification

A structural condition where an effect, declaration, authority, constraint, or state increases in scope or intensity as it propagates beyond declared bounds.

PAT-0370

Redundant Declaration

A structural condition where multiple declarations produce equivalent structural effect without semantic differentiation.

PAT-0200

Reference Instability

A structural condition where references, identifiers, links, or anchors change across equivalent evaluations without a declared cause.

PAT-0160

Schema Breakage

A structural condition where an instance, graph, payload, or object violates the type, shape, or rule requirements of a declared schema.

PAT-0380

Silent Mutation

A structural condition where a change occurs without a corresponding declared update, authority update, or version change.

PAT-0390

Threshold Breach

A structural condition where an observed metric, value, state, or condition exceeds a declared quantitative or qualitative threshold.

PAT-0400

Unbounded Scope

A structural condition where an operation, authority, rule, or expansion has no declared upper bound, boundary, or termination condition.

PAT-0410

Unconstrained Expansion

A structural condition where a region, process, authority, or effect expands without governing constraints limiting growth.

PAT-0420

Undeclared Side Effect

A structural condition where an operation modifies regions outside its declared target scope without a declared propagation or side-effect rule.
