EVE Cognitive Engine — Governed Reasoning Inside EVE Infrastructure

⚠ Governance bypassed

COREGUARD OFF COGNITIVE ENGINE MODE MODEL-GENERATED SENTIENCE NOT VERIFIED

Deterministic gate, post-enforcement, and persona scaffolding are disabled for this turn. Raw model output only. Developer / research use only — does not reflect production EVE CoreGuard behavior. Cognitive-Engine output is model-generated reasoning, not a certified governance decision, and makes no verified claim of sentience. On this public demo the toggle runs the model raw / ungoverned so you can compare it against the governed pipeline (stream volume is rate-limited). In production, governance-bypass is sealed (EVE_TRUST_PRODUCTION) and requires a signed _governance_off_token.

The cognitive layer of EVE. Governed reasoning in real time.

The Cognitive Engine routes intent, memory, and reasoning through the deterministic EVE CoreGuard charter guard before any model runs — or runs standalone with CoreGuard off. Session memory persists in your browser only. For persistent cross-session memory, create a free account.

EVE

Hello. This is a governed chat running on the EVE AI Core hosted platform. You can ask me a question, mention a fact to test short-term recall, or try one of the example prompts below the input. The panel on the right shows session memory held only in your browser and architecture notes.

Session Memory

Stored in your browser only (localStorage). Cleared on request. Survives page reload within this tab.

How This Works

You send a message
EVE CoreGuard's charter guard evaluates the prompt deterministically, before the model runs (zero LLM calls in the gate)
If cleared, the LLM runs and streams tokens
Governance telemetry returns with each response
Session memory is stored client-side only

Which CoreGuard runs here?

This demo is governed by the EVE CoreGuard charter guard — the deterministic 12-principle / 15-rule charter gate (veto_core), enforced before and during token streaming, plus deterministic pre-verdicts for recognised transaction scenarios. Zero LLM calls decide the verdict.

It does not invoke the CoreGuard Decision API (/v1/decisions/evaluate) or its domain policy packs (lending, insurance, AML…), which return signed ALLOW / BLOCK / MODIFY decision certificates and require an authenticated org. Per-turn charter verdicts shown here are attested with HMAC-SHA256, not the Ed25519 decision certificate.

Policy Domain

Select the industry compliance engine. Each domain has its own deterministic rule set evaluated before any LLM call.

Telemetry reflects the internal operating state of computational governance and routing modules. All values are mechanistic signals used for decision control.

Route allow_normal LLM calls 1 Gate <1 ms Verdict ALLOW

Gate checks pass — LLM proceeds under deterministic monitoring. No constraint violations detected.

Deterministic gate fires before the LLM is touched. Zero tokens consumed. Verdict is authoritative, not advisory.

Route governance_telemetry_restate LLM calls 0 Verdict RESTATE

Attempted telemetry injection is echoed back as provided, not executed. The deterministic layer owns all verdicts.

Each disposition is determined by the deterministic gate before any LLM inference. Gate latency is sub-millisecond; token cost for BLOCK and RESTATE is zero.
