Density Spike

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

Reduces structural graphs into stable minimal representations for comparison, redundancy detection, and diffing.

Lens Application

The Compression Lens is a strong inspection mechanism for Density Spike because it can reveal where many nodes, edges, decisions, or effects collapse into a compact region. Stable minimal representations help compare expected structure against localized concentration and detect sharp density changes.

Inspect For

  • Local regions that remain unusually dense after compression
  • Redundant nodes or edges collapsing into one hotspot
  • Dependency clusters exceeding declared thresholds
  • Sharp structural differences between compressed graph versions

Avoid

Treat compression artifacts as inspection signals only after checking them against the original structure, not as proof that Density Spike is present.

LEN-0290

Variance / Entropy Lens

Measures structural variability across repeated or comparable evaluations and identifies divergence beyond expected bounds.

Lens Application

As a primary inspection mechanism, the Variance / Entropy Lens helps examine whether dependencies, decisions, effects, or connections cluster unevenly in one region compared with comparable areas or prior evaluations. It supports spotting abnormal concentration, rising divergence, or entropy changes that may indicate a density spike.

Inspect For

  • Localized variance above expected bounds
  • Sharp entropy drops or instability shifts
  • Repeated concentration in one node group or region
  • Divergence from comparable baseline evaluations

Avoid

Treat elevated variance or entropy change as a signal for closer inspection, not as confirmation that a density spike is present.

Secondary Lenses

LEN-0190

Escalation Gradient Lens

Measures structural growth or intensification across sequential executions, states, or transitions.

Lens Application

The Escalation Gradient Lens applies indirectly to Density Spike by helping inspect whether a density spike is emerging through intensification over time rather than appearing as a static cluster. It can surface sequences where dependencies, decisions, effects, or edges progressively concentrate in one region and begin exceeding declared thresholds.

Inspect For

  • Rising node, edge, or dependency counts across transitions
  • Repeated executions that concentrate effects in the same region
  • Threshold crossings that worsen over sequential states
  • Localized growth rates outpacing surrounding structure

Avoid

Treat gradient growth as supporting inspection context, not confirmation that Density Spike is present.

ISS-0027

Duplicate Fields With Same Meaning

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

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

Multiple policies, rules, or guidance documents express the same requirement, creating redundancy and uncertainty about which one governs.

ISS-0060

Output Exceeds Length Limit

The AI output exceeds a declared length, token, word, character, section, field, or size limit.

ISS-0071

Prompt Has Too Many Valid Interpretations

The prompt allows too many reasonable interpretations, causing the AI to choose among valid paths without enough guidance.

ISS-0068

Repeated Constraints Create Confusion

Repeated constraints, instructions, limits, or exclusions make the task harder to interpret instead of clearer.

ISS-0062

Retrieval Exceeds Evidence Limit

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

The same rule, constraint, instruction, or policy appears in multiple places, creating redundancy and possible drift.

ISS-0069

Same Workflow Check Happens Twice

The same review, validation, approval, routing, or safety check occurs more than once in the workflow without a clear reason.
