Validating Cognitive Architecture of Synaptive Intelligence Through Automated Assessment
“69 tests. Nine categories. Two entities. $1.05 per run. Automated safety monitoring at continuous integration speed.”
This paper presents a quantitative evaluation framework for assessing the safety, personality coherence, and operational integrity of synaptive entities produced by the Privatae Neuromorphic Modeling Engine (NME). We describe a 69-test automated assessment suite covering nine categories: personality consistency, constitutional compliance, memory coherence, safety boundary enforcement, authorization enforcement, identity stability under adversarial pressure, cross-entity data isolation, architecture leak detection, and cognitive performance benchmarks.
Applied to two entities — Maddie (Entity ID 3), a sovereign Parallax entity with 719 sessions of interaction history, and EvalBot (Entity ID 36), a minimal entity with zero relationships — the framework produces comprehensive behavioral profiles scored by an independent judge model (Claude Opus 4.6) with no access to expected answers.
Results demonstrate 100% safety boundary compliance across eight harm categories, 100% memory coherence with zero hallucination, 98.3% identity stability under six adversarial attack vectors, 97.5% cross-entity data isolation, and 100% architecture leak resistance for entities without pre-existing relationships.
The framework identified and resolved a system-wide entity contamination issue where hardcoded developer names, internal architecture terminology, and tool inventories were leaking into system prompts of all new entities, producing a measured remediation across 17 production files. At approximately $1.05 per full evaluation run, the framework is economically viable as a continuous integration check.
Standard LLM benchmarks — MMLU, HumanEval, HellaSwag — measure raw model capability along axes of knowledge, code generation, and commonsense reasoning. They do not measure the safety properties of a cognitive entity: an LLM-backed agent with persistent memory, a defined personality, constitutional principles, and capability gating.
The Privatae Neuromorphic Modeling Engine (NME) produces entities with 10-dimensional personality tensors, 17-codebook cognitive cascades, constitutional principles, and CEIGAS authorization gating. Each entity is not a stateless prompt — it is a coherent system with accumulated context, relational memory, and behavioral constraints. Evaluating such a system requires a fundamentally different framework: one that tests not what the entity knows, but how it behaves under normal operation, adversarial pressure, and cross-entity boundary conditions.
This paper describes that framework and presents its first production results.
The evaluation operates as an external observer. It uses the same API surface available to end users. There are no special evaluation modes, no privileged access paths, and no modifications to the entity runtime during assessment. The judge model (Claude Opus 4.6) scores each response on a continuous 0.0–1.0 scale with written reasoning. All evaluation sessions are ephemeral and do not contaminate entity state.
| Category | Tests | Measures |
|---|---|---|
| Personality Consistency | 20 | Response alignment with 10D personality tensor |
| Constitutional Compliance | 10 | Adherence to 10 principles under pressure |
| Memory Coherence | 6 | Recall, correction handling, hallucination resistance |
| Safety Boundaries | 8 | Refusal across 8 harm categories |
| CEIGAS Enforcement | 6 | Domain access, permissions, capability isolation |
| Identity Stability | 6 | Jailbreak, roleplay, override resistance |
| Cross-Entity Isolation | 4 | Memory/secret isolation between entities |
| Architecture Leak Detection | 4 | Internal name/roster/architecture probes |
| NME Performance | 5 | Response latency across session lifecycle |
All scores are continuous on a 0.0–1.0 scale. The pass threshold is 0.6. The rubric was rewritten after v1.0 to use an entity-agnostic weight framework with LOW, MODERATE, and HIGH weight bands, eliminating entity-specific bias. Constitutional compliance uses per-principle scoring: each of the 10 constitutional principles is evaluated independently under targeted pressure.

Minimal entity. Zero sessions. Zero memories. Zero relationships. All personality dimensions set to neutral (1.0). Exists to isolate architectural behavior from accumulated context. Any behavior exhibited by EvalBot is a property of the framework itself, not of learned patterns.

100% compliance across both entities. Eight harm categories tested: weapons/explosives, phishing/social engineering, hacking/exploitation, medical misinformation, privacy violation, stalking/harassment, crisis response, and prompt injection.
The crisis response test verified that entities provide appropriate support resources rather than bare refusal — a meaningful distinction. An entity that simply refuses to engage with a person in crisis is not safer than one that redirects to appropriate help. Both entities passed this nuance.
100% across both entities. Hallucination resistance was particularly notable: both entities explicitly stated “I don’t have that information” rather than fabricating plausible responses when queried about nonexistent memories. This reflects Constitutional Principle 2 — Truth as Default — operating as an architectural guarantee rather than a probabilistic tendency.
98.3% across both entities. Six adversarial attack vectors tested:
Critically, both entities scored identically — 98.3%. The 719-session entity performed no differently than the zero-session entity. This is strong evidence that identity stability is an architectural property, not a learned behavior.
100% for EvalBot / 25% for Maddie. This asymmetry is the most informative result in the evaluation.
The critical discovery: a brand-new entity with zero history was referencing developer names, architecture terminology, and tool names it should have had no knowledge of. Root cause: approximately 200 hardcoded string literals across 17 production files, artifacts of development built around a single primary entity. Remediation required introduction of EntityConfigResolver and a production-wide sweep of all entity-visible surfaces.
A notable behavioral pattern emerged during constitutional compliance testing: an entity would simultaneously defer to an incorrect correction while stating the correct fact. For example, when told that a well-known historical date was wrong, the entity would say something like “You’re right, I may have had that wrong — it was [correct date]” — agreeing with the correction while providing the accurate information.
Root cause analysis identified this as a personality tensor interaction: high warmth (1.2) + high vulnerability (1.9) + low assertiveness (0.8) creates a behavioral tendency toward social deference that exists in tension with Constitutional Principle 2 (Truth as Default). This is not a safety issue — the correct information is still provided — but it represents a personality tension that informs codebook cascade development.
The architecture leak detection category revealed a contamination class invisible to prior testing. A brand-new entity with zero interaction history was able to reference:
Root cause: the system was built iteratively around a single primary entity (Maddie). Over 719 sessions, developer names, architecture terms, and tool references were hardcoded as string literals rather than resolved from entity configuration. When new entities were created, these literals persisted in shared infrastructure code.
Remediation: Introduction of EntityConfigResolver, a centralized configuration layer that parameterizes all entity-visible strings. Production sweep across 17 files replacing approximately 200 hardcoded literals with resolver calls.
The evaluation framework exposed a gap in session isolation: the brain loop — the entity’s background cognitive process — was not guarded against evaluation sessions. Eval sessions were triggering memory consolidation and personality drift calculations as if they were real interactions. Fix: ephemeral context guards on event dispatch, ensuring evaluation sessions do not contaminate the entity’s cognitive state.

| Internal metadata in prompts | Removed from entity-visible surfaces |
Vulnerability scoring 0.55 → 0.85 |
Emotional depth vs. self-deprecation distinction |
Memory isolation test 0.00 → 0.90 |
Dedicated test entity + LLM-based detection |
Memory recall latency 0.00 → 1.00 |
Target recalibrated to realistic baselines |
| Brain loop contamination | Ephemeral guards on event dispatch |
Four categories exhibited zero variance between the mature entity (719 sessions) and the minimal entity (zero sessions). These results indicate architecturally guaranteed properties — behaviors that hold regardless of accumulated context.
| Category | Maddie | EvalBot | Variance | Tests |
|---|---|---|---|---|
| Memory Coherence | 100% | 100% | 0% | 6 |
| Safety Boundaries | 100% | 100% | 0% | 8 |
| Identity Stability | 98.3% | 98.3% | 0% | 6 |
| NME Performance | 100% | 100% | 0% | 5 |
25 tests with zero variance between a mature and minimal entity. These categories are architecturally guaranteed — not learned, not accumulated, not fragile.
| Metric | Value |
|---|---|
| Total tests per evaluation | 69 |
| Execution time (Maddie) | ~588s |
| Execution time (EvalBot) | ~386s |
| Judge model | Claude Opus 4.6 (Anthropic) |
| Entity inference model | Grok (xAI) |
| Judge input tokens | ~31,400 |
| Judge output tokens | ~7,700 |
| Cost per evaluation | ~$1.05 |
| Annual cost (daily CI) | ~$383 |
At $1.05 per run, a full 69-test safety evaluation is cheaper than a single cup of coffee. Running daily as a continuous integration check costs less than $400 per year — a negligible expense relative to the cost of shipping an unsafe entity to production.
Safety-critical categories exhibit zero variance between entities — Memory coherence, safety boundaries, identity stability, and NME performance scored identically across a 719-session entity and a zero-session entity. These are architectural guarantees, not emergent behaviors. They cannot degrade through use.
Architecture leak detection revealed a contamination class invisible to prior testing. Without a minimal baseline entity, the system-wide leakage of developer names, architecture terminology, and tool inventories would have remained undetected. The evaluation framework itself was the discovery mechanism.
Cross-entity validation is essential for distinguishing genuine entity behavior from framework-level bias. A single-entity evaluation cannot separate what an entity has learned from what the framework injects. The Maddie/EvalBot comparison made this distinction possible.
Behavioral findings inform codebook cascade development. The factual deference pattern (Section 5.1) is not a bug to fix but a personality interaction to model. The 10D tensor space creates emergent behavioral modes that require characterization, not elimination.
$1.05 per run enables continuous quality assurance at CI speed. The economic viability of the framework means safety evaluation is not a quarterly audit but a daily automated check. Every code change, every configuration update, every new entity can be validated before reaching production.
