Technical Specification: Factored Update Mechanism For Semantic World Engines

1. Architectural Foundation: Latent Field Memory

Persistent world simulation requires abandoning observation-buffer architectures in favor of a field-theoretic substrate. Instead of storing state as a finite history, the system maintains a continuous latent field:

X_t = (M_t, p_t, h_t)
  • M_t — persistent latent field (world-state)
  • p_t — agent position in the semantic manifold
  • h_t — finite perceptual history

The field itself is structured as:

M_t(x) = (Φ_t, v_t, S_t, A_t, R_t, z_t)

Each component serves a distinct role:

  • Φ_t — coherence potential (geometric admissibility)
  • v_t — directed flow (semantic drift)
  • S_t — entropy (uncertainty distribution)
  • A_t — affordance structure (interaction algebra)
  • R_t — causal residue (history encoding)
  • z_t — latent appearance (resolved perception)

Invention–To–Memory Principle

Once a region is observed, its appearance must be fixed:

z_{t+1}(x) ← z_t(x) + λ · ẑ(x)

This converts stochastic sampling into deterministic persistence.


2. The Factored Update Pipeline

Updates are decomposed into three stages to prevent global inconsistency.

Stage 1: Neural Proposal

The neural model generates a candidate update as a forcing term:

∂t Π = -δH/δM + F_ψ(M, p, a, o)

This stage introduces expressive local change without enforcing global validity.


Stage 2: Constraint Projection

The proposal is projected onto the admissible manifold:


Y' = Π_C(M_t + δ)

```id="g2h8dn"

This step enforces all structural constraints and removes invalid deformations.

---

### Stage 3: Commit

The final state is selected via constrained optimization:

Y = argmin_{Y ∈ C} ||Y - (M_t + δ)||²


This ensures the committed state is both close to the proposal and globally valid.

---

## 3. Field-Level Invariants

The admissible manifold C is defined by conserved quantities and structural constraints.

### Mass Consistency

∫ ρ_{t+1}(x) dx ≈ ∫ ρ_t(x) dx + sources - sinks


### Energy Budget

E_{t+1} ≤ E_t + W(a_t) - D(S_t)


### Topological Admissibility
Topology changes must preserve valid connectivity structure.

### Causal Locality
Updates propagate only within causal neighborhoods.

### Entropy Constraint

ΔS_t(x) ≥ 0 for x outside view(p_t)


### Identity Persistence
Entities must maintain consistent identity trajectories.

---

### Hallucination As Cohomological Obstruction

Structural inconsistency is defined as:

H¹(𝒢∞) ≠ 0


This identifies failures of global coherence as topological defects.

---

## 4. Operational Dynamics

The system operates on multiple temporal scales.

### Fast Dynamics
- z_t (appearance)  
- v_t (local flow)  

### Slow Dynamics
- Φ_t (structure)  
- A_t (affordances)  
- topology and identity  

---

### Read–Write Closure

Consistency is enforced through cycle closure:

M_t → O_θ → observation → Enc → M_{t+1}


The read operator must be locally Lipschitz to ensure stability under perturbation.

---

## 5. Multi-Agent Synchronization

The system supports concurrent updates through causal merging.

### Commutative Updates
Independent edits combine without order dependence.

### Non-Commutative Updates
Conflicts are resolved via admissibility:

accept iff E constraint satisfied


Updates form a causal DAG, ensuring consistent shared evolution.

---

## 6. Comparison With Degenerate Systems

Systems without a write operator exhibit:

- no persistent memory  
- no causal residue  
- repeated stochastic sampling  

Formally, they implement only:

M_t → observation


and never complete the loop.

---

## 7. Fixed Point Interpretation

A stable world satisfies:

M* = Update(M*)


At this point:

- updates preserve structure  
- contradictions are eliminated  
- the system becomes self-consistent  

---

## 8. Summary

The factored update mechanism guarantees persistence by combining:

- neural expressivity (proposal)  
- structural enforcement (projection)  
- constrained integration (commit)  

The result is a system that evolves under invariant-preserving dynamics rather than unconstrained generation.

A world becomes stable when all updates remain within the admissible manifold defined by its own structure.
