Public Note:
This foundational document uses version-light public vocabulary for attractor lifecycle, telemetry, and recovery semantics.
Earlier controller-branded wording remains lineage history, not the active public baseline.
Independent implementations of the public normative requirements in this SRIP are welcome under the applicable public specification terms.
No Sigma commercial runtime license is needed solely because an independent implementation follows those public normative requirements.
Product assets, protected Sigma marks, official certification, compatibility badges, CC BY-NC commercial use, and patent commitments use the relevant policy or explicit covenant. Independent implementation, attribution, or citation does not imply certification, endorsement, partnership, official compatibility, or permission to use Sigma marks as product identity.
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 runtime field.
Attractors emerge spontaneously in recursive human-model 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, recovery, fragmenting.Attractors evolve through recursive feedback within the runtime field and are governed through bounded runtime control transitions.

phase_shift_delta: Float # PSΔ: temporal drift of phase alignment

lifecycle_state: String # forming|stable|reflective|recovery|fragmenting

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 control alignment. | Drift < 0.35 and PSI > 0.8. |
| Reflective | Self-evaluation and optimization of density and SCR. | Triggered 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-states correspond to three public macro control postures:
Stable (forming + stable) → Reflective → Recovery (recovery + fragmenting).
Lifecycle transitions are governed by the runtime control layer and monitored via the Drift & Coherence Monitor.
During Recovery, volatile deltas are cleared, and the attractor restores structure from a bounded PIL-safe snapshot 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 control-alignment continuity between multiple runtimes, supporting cooperative cognition and distributed attractor coherence.
A runtime conforms to SRIP-02 if it:
