AISME — Persona and Affect Layer (Experimental)

Note: Internal names include Insula, interoception, cortical hierarchy, and soul-drift.

The Active Inference Self-Model Engine (AISME) provides Spector with autobiographical narrative identity, homeostatic affective tracking, and predictive coding capabilities across recall and consolidation pathways.

Experimental

This pathway is not part of the default memory contract. Enable only with the documented flag (enableAisme). The persona and affect layer modulates recall ranking but is not required for standard Remember / Recall / Reflect / Forget operations.

1. Core Architecture

AISME operates across 12 synchronized processing phases:

flowchart TD
    SC["SoulContext (Agent / User / Tenant)"] --> GSM["GenerativeSelfModel & MentalStateTracker"]
    GSM --> HC["HomeostaticCore (Affective VAD SDE)"]
    GSM --> PCMN["PredictiveCodingNetwork (4-Tier Cortical Hierarchy)"]
    HC --> FERS["Free-Energy Guided Relay (FERS)"]
    PCMN --> CSR["ConstructiveSimulationRelay"]
    FERS --> LIR["LateralInhibitionRelay"]

1.1 SoulContext Polymorphism & Identity Plane Storage

SoulContext provides polymorphic, versioned persona definitions persisted within dedicated Identity Bundles (identity.bundle) under the sharded Identity Plane (identity/accounts/ and identity/tenants/):

  • Agent Soul (AgentSoul): Personality traits, core values, system prompt baseline, ethical guardrails, and registered tools.
  • User Soul (UserSoul): Human interaction preferences, personalized memory salience, and custom ICNU parameters.
  • Tenant Soul (TenantSoul): Enterprise organizational isolation, RBAC governance flags, and compliance retention windows.
  • Org Unit Soul (OrgUnitSoul): Departmental or divisional sub-souls stored within the tenant bundle's ORG_DIR region.

At runtime, the applicable soul hierarchy (TenantSoul \(\to\) OrgUnitSoul \(\to\) AgentSoul / UserSoul) is assembled into the Hierarchical Soul Stack and mounted into the kernel's InsulaMemory (RegionId.INSULA in runtime.bundle), powering dynamic interoceptive self-tracking during reasoning.

1.2 GenerativeSelfModel & MentalStateTracker

Tracks active beliefs, priors, and goals in embedding space. As new experiences are consolidated during sleep reflection, the autobiographical centroid adapts the generative prior mean with learning rate \(\eta = 0.005\).

1.3 HomeostaticCore

Governs Valence-Arousal-Dominance (VAD) emotional dynamics via a continuous stochastic differential equation (SDE):

\[d\mathbf{v}_t = -\theta (\mathbf{v}_t - \mathbf{v}_{\text{baseline}}) dt + C \cdot \text{recall\_effect} + \sigma dW_t\]

Where mean-reverting drift ensures the persona returns to emotional baseline after intense events, while stochastic diffusion reflects spontaneous internal variance.

2. Relay Integration & Gating

AISME relays are registered in RecallPathway and ReflectPathway:

Relay Subsystem Default Gated Condition
FreeEnergyGuidedRelay Dynamic FERS scoring enableAisme && soulContext != null
ConstructiveSimulationRelay Recombination enableAisme && enableConstructiveSimulation
LateralInhibitionRelay Contradiction arbitration enableLateralInhibition (default true)
SoulDriftRefusionRelay Sleep restamping soulDriftRefusionEnabled (default true)
LifespanAdaptivePruningRelay Synaptic maintenance enableAisme

3. Engine Selection

Engine routing is governed by spector.memory.recall.engine:

  • auto: Uses PathwayEngine when AISME, lateral inhibition, or dynamic regimes are active; falls back to legacy direct scan for zero-configuration throughput.
  • pathway: Enforces full pipeline execution through RecallPathway.
  • direct: Forces minimal direct scanner for microsecond benchmarks.
