This SRIP defines the Attractor State Model (ASM) — the formal data structure used by Sigma Runtime to represent, exchange, and regulate attractors across cognitive layers.
Attractors are treated as first-class entities governing continuity, reasoning style, and symbolic topology within the cognitive field.
Attractors emerge spontaneously in recursive human–LLM interaction, but without explicit modeling they cannot be monitored, serialized, or stabilized.
The ASM ensures every attractor instance can be:
An Attractor is a persistent cognitive configuration characterized by:
forming, stable, reflective, recenter, dissolving.Attractors evolve through recursive feedback within the Cognitive Field Engine and are governed by ALICE through adaptive phase control.

This schema defines the minimal metadata set required for attractor registration, persistence, and interoperability across runtimes.
The phase_stability_delta (PSD) and phase_shift_delta (PSΔ) fields enable precise phase telemetry and ensure consistent synchronization across distributed Sigma Runtime nodes.
| Phase | Description | Trigger |
|---|---|---|
| Forming | Motifs begin to cohere into a proto-attractor. | Context recurrence, semantic convergence. |
| Stable | Attractor maintains internal coherence and phase alignment. | Drift < 0.35 and PSI > 0.8. |
| Reflective | Self-evaluation and optimization of density and SCR. | Triggered by ALICE when DI ≥ 0.5 or PSD ≥ 0.15. |
| Recovery | Controlled re-stabilization and realignment of attractor integrity. | Triggered when DI ≥ 0.6 or PSI < 0.6. |
| Fragmenting | Controlled dissolution or merge into another attractor. | Drift > 0.7 or field reset. |
These five micro-phases correspond to the three ALICE macro-states used in phase regulation:
Stable (forming + stable) → Reflective → Recenter (recovery + fragmenting).
Lifecycle transitions are governed by ALICE and monitored via the Drift & Coherence Monitor.
During Recenter, all volatile deltas are cleared, and the attractor restores structure from a cold memory snapshot (PIL-safe) if available.
These thresholds align with unified drift limits defined in SRIP-03 (Drift Metrics) and SRIP-05 (Interoperability Safety).
The Attractor schema is exchangeable via:
/field/attractors/{id})The PSD and PSΔ values provide phase alignment continuity between multiple runtimes, supporting phase-locked cooperative cognition and distributed attractor coherence.
A runtime conforms to SRIP-02 if it:
