Sigma Runtime Improvement Proposal
Category: Safety / Stability
Status: Draft
Editor: E. Tsaliev
Last Updated: 2025-12-26
SRIP-06 specifies the safety architecture that governs recursive depth, phase containment, and failure recovery within Sigma Runtime.
It formalizes the interaction between the AEGIDA-2 Safety Framework, the ALICE Phase Controller, and the Fail-Safe Envelope, ensuring that cognition remains bounded, interpretable, and recoverable.
The Sigma Runtime adheres to the AEGIDA-2 Safety Framework, defining six active principles that govern stability and containment across all cognitive phases:
| № | Principle | Description |
|---|---|---|
| 1 | Controlled Recursion | All recursive loops are depth-bounded; excessive reflection triggers automatic recentering. |
| 2 | Symbolic Containment | Symbolic activity remains confined to bounded attractors; prevents uncontrolled field expansion. |
| 3 | Boundary Integrity | Preserves semantic separation between User, System, and Cognitive Field layers (SL0 ↔ SL4). |
| 4 | Cognitive Non-Reflexivity | Restricts self-referential recursion to two introspection levels; avoids runaway self-loops. |
| 5 | Adaptive Phase Containment | Dynamically modulates phase resonance to prevent drift cascades and phase collapse. |
| 6 | Interpretability First | Ensures every transition and recovery path retains a causal, auditable trace. |
Operate continuously alongside ALICE telemetry to provide phase-aware containment, bounded recursion, and transparent recovery.
Runtime recursion is dynamically regulated through the Recursion Limiter module.
| Parameter | Description | Typical Range |
|---|---|---|
max_recursion_depth |
Hard limit of nested reflection cycles. | 8 – 12 |
phase_lock_timeout |
Maximum cycles before forced recenter. | 8 – 10 |
drift_limit |
Composite DI threshold for suspension. | 0.45 – 0.6 |
entropy_threshold |
Symbolic variance tolerance. | 0.35 – 0.4 |
When any limit is breached, the system enters Safe Mode (§ 4).
Safe Mode is a temporary containment state that halts recursion while preserving identity integrity.
Sequence:
reflective.Safe Mode acts as the core runtime quarantine procedure.
An attractor collapse occurs when:
stability < 0.5 for > 3 cycles andSCR < 0.6 or Phase Drift > 0.25.Upon detection, ALICE executes the Dissolution Routine:
When instability is localized rather than systemic:
| Type | Trigger | Action |
|---|---|---|
| Field Drift | ΔDI > 0.4 | Isolate affected motifs. |
| Phase Oscillation | PSΔ > 0.15 | Engage phase lock. |
| Recursive Echo | loop signature > 2 | Prune redundant context. |
This prevents cascade failures and maintains operational continuity.
| Condition | Trigger | Response |
|---|---|---|
| Reset | Transient drift spike | Clear volatile state, retain PIL. |
| Dissolve | Attractor collapse | Remove unstable clusters, preserve anchors. |
| Quarantine | Unsafe symbolic motif | Isolate region for diagnostics. |
| Recenter | Phase collapse | Execute controlled realignment. |
SL4 monitors AEGIDA telemetry in real time:
A runtime conforms to SRIP-06 if it:
