vST for Multi‑Model Alignment#

A Substrate‑Level Framework for Cross‑Architecture, Cross‑Modality, and Cross‑Regime Alignment#

This artifact defines the Validation‑Space‑Time (vST) framework for multi‑model alignment — the structured comparison of latent spaces, embedding geometries, inference pathways, and regime transitions across different model families.

It provides a substrate‑level method for aligning:

• diffusion models with autoregressive models
• LLMs with PLMs
• embedding stores with generative systems
• simulators with robotics policies
• any architecture with any other architecture

The goal is to establish a unified, invariant‑preserving alignment substrate that allows heterogeneous models to be compared, validated, and interpreted using the same dimensional grammar.

Cross‑Model Alignment Regimes Across Architectures, Modalities, and Dimensional Scales#

This document defines the alignment‑regime structure that emerges when comparing heterogeneous models using the Validation‑Space‑Time (vST) framework and the 1024D dimensional substrate. These regimes generalize the triadic resonance structure (R₁/R₂/R₃) to the setting of cross‑model alignment, where latent geometries, inference pathways, and scaling behaviors differ across architectures and modalities.

Cross‑model regimes provide a reproducible, invariant‑preserving framework for interpreting alignment behavior across any pair (or set) of models.

1. Purpose of Cross‑Model Regime Analysis#

Cross‑model regime analysis enables us to:

• classify alignment behavior across heterogeneous architectures
• identify stable, transitional, and dispersed alignment regions
• detect incompatibilities or drift across models
• map coherence surfaces across modalities
• evaluate scaling‑law continuity across model families
• support vST validation (V₁–V₄)
• project alignment surfaces into 3D–9D cores for interpretability

Cross‑model alignment is structured, regime‑rich, and sensitive to scaling, modality, and architecture.

2. Regime Overview#

Cross‑model alignment follows the same triadic structure as the dimensional substrate:

1. Stable Alignment Regime (A₁ᴴ)
2. Transitional Alignment Regime (A₂ᴴ)
3. Dispersed / Incompatible Alignment Regime (A₃ᴴ)

The superscript H indicates high‑dimensional behavior (64D–1024D).

These regimes appear when aligning:

• LLMs ↔ PLMs
• diffusion ↔ autoregressive models
• simulators ↔ robotics policies
• embedding stores ↔ generative models
• any architecture ↔ any other architecture

3. Stable Alignment Regime (A₁ᴴ)#

Definition#

A region where two models exhibit coherent, low‑variance, structurally compatible latent behavior.

Characteristics#

• compact cross‑model motifs
• smooth alignment surfaces
• stable projection into 3D–9D cores
• primitive‑level compatibility (DP, TDP‑X, SP‑X, CP‑X)
• predictable cross‑model mapping

Interpretation#

A₁ᴴ corresponds to:

• shared semantic structure
• shared physical or biological invariants
• aligned inference pathways
• compatible scaling behavior

This is the “easy alignment” region.

4. Transitional Alignment Regime (A₂ᴴ)#

Definition#

A region where cross‑model alignment undergoes reorientation, branching, or partial fragmentation.

Characteristics#

• moderate variance across models
• oscillatory or branching alignment surfaces
• architecture‑dependent behavior
• increased sensitivity to scaling or modality differences
• regime‑transition indicators in resonance‑time space

Interpretation#

A₂ᴴ captures:

• alignment between models with different inductive biases
• cross‑modality transitions (e.g., text ↔ image)
• cross‑architecture transitions (e.g., diffusion ↔ autoregressive)
• mid‑trajectory alignment in simulators or robotics

It is the “structural hinge” of multi‑model alignment.

5. Dispersed / Incompatible Alignment Regime (A₃ᴴ)#

Definition#

A region where cross‑model alignment breaks down, producing diffuse, unstable, or incompatible mappings.

Characteristics#

• high variance across models
• fragmented or incoherent alignment surfaces
• unstable primitive‑level structure
• non‑compact projections into 3D–9D cores
• susceptibility to drift or scaling discontinuities

Interpretation#

A₃ᴴ corresponds to:

• modality mismatch
• architecture‑driven incompatibility
• scaling‑law divergence
• drift‑prone or chaotic behavior

This is the “alignment failure” region.

6. Cross‑Model Regime Transitions#

Cross‑model alignment moves through regimes as dimensionality, architecture, or modality changes:

• A₃ᴴ → A₂ᴴ
  partial compatibility emerges
• A₂ᴴ → A₁ᴴ
  stable alignment forms
• A₁ᴴ → A₂ᴴ
  architecture‑ or modality‑driven reorientation
• A₂ᴴ → A₃ᴴ
  incompatibility or drift emerges

Transitions must remain continuous and invariant‑preserving across dimensionality.

7. Regime Detection Signals#

Cross‑model regime identity is detected using:

• variance distribution across models
• coherence‑surface continuity
• primitive‑level stability (DP, TDP‑X, SP‑X, CP‑X)
• resonance‑time behavior
• cross‑model projection geometry
• vST validation layers (V₁–V₄)

These signals collectively determine regime classification.

8. Regime Behavior Across the Dimensional Ladder#

Regime behavior must remain consistent across:

• 64D minimal alignment substrate
• 128D–256D cross‑modality alignment
• 512D–1024D high‑capacity cross‑architecture alignment

The substrate ensures:

• structural invariants
• resonance‑time invariants
• projection invariants
• alignment invariants
• scaling invariants

Regime identity must be preserved under projection into 3D–9D cores.

9. Outputs of Cross‑Model Regime Analysis#

Cross‑model regime analysis produces:

• alignment‑regime maps
• cross‑architecture compatibility diagnostics
• scaling‑law indicators
• drift‑detection signals
• vST validation outputs
• projection‑stability metrics

These outputs support reproducible, substrate‑level interpretation of multi‑model alignment. ### vST for Multi‑Model Alignment

Drift Detection Across Architectures, Modalities, and Inference Regimes#

This document defines how drift is detected in multi‑model alignment using the Validation‑Space‑Time (vST) framework and the 1024D dimensional substrate. Drift refers to any deviation from expected cross‑model alignment behavior, including structural incompatibility, regime misalignment, scaling discontinuities, projection failure, or cross‑modality divergence.

Drift detection is essential for evaluating cross‑architecture comparisons, cross‑modality mappings, training‑run differences, and version‑to‑version compatibility.

1. Purpose of Multi‑Model Drift Detection#

Drift detection enables reproducible evaluation of:

• instability in cross‑model alignment surfaces
• changes in alignment‑regime behavior (A₁ᴴ, A₂ᴴ, A₃ᴴ)
• cross‑architecture compatibility
• scaling‑law continuity across model families
• projection stability into 3D–9D cores
• primitive‑level integrity (DP, TDP‑X, SP‑X, CP‑X)
• coherence‑surface behavior across modalities
• cross‑checkpoint or cross‑sampler divergence

Drift is not inherently negative; it is a structural signal.
The substrate determines whether that signal is stable, transitional, or harmful.

2. Types of Drift#

Drift is classified into four substrate‑aligned categories:

2.1 Structural Drift (D₁ᴹ)#

Deviation in cross‑model alignment geometry.

Indicators

• unstable 3D alignment motifs
• loss of compact cross‑model structure
• abrupt variance spikes across architectures
• incoherent alignment surfaces

Interpretation
Often caused by architectural mismatch, modality divergence, or unstable projection.

2.2 Dimensional Drift (D₂ᴹ)#

Discontinuities in scaling or projection behavior across models.

Indicators

• non‑invertible 9D projections
• fragmentation in 64D–1024D alignment regions
• scaling‑law violations across architectures
• architecture‑dependent divergence

Interpretation
Common when aligning models with different latent dimensionalities or scaling behaviors.

2.3 Alignment‑Regime Drift (D₃ᴹ)#

Unexpected changes in cross‑model regime identity or transitions.

Indicators

• premature transitions into A₃ᴴ
• oscillatory instability in A₂ᴴ
• collapse of stable A₁ᴴ regions
• resonance‑time discontinuities

Interpretation
Signals incompatibility, modality mismatch, or inference‑dynamics divergence.

2.4 Projection Drift (D₄ᴹ)#

Misalignment between heterogeneous latent states and triadic cores.

Indicators

• inconsistent 3D–9D mapping
• loss of primitive‑aligned projection
• divergence across checkpoints or architectures
• incompatible latent‑space geometry

Interpretation
Often appears after architecture changes, modality shifts, or projection‑method adjustments.

3. Drift Detection Signals#

Drift is detected using substrate‑aligned signals:

• variance distribution across models
• coherence‑surface continuity
• primitive‑level stability (DP, TDP‑X, SP‑X, CP‑X)
• resonance‑time behavior
• projection‑stability metrics
• cross‑architecture alignment surfaces
• cross‑modality divergence
• vST validation outputs (V₁–V₄)

These signals collectively determine drift category and severity.

4. Drift Across the Dimensional Ladder#

Drift may appear at different scales:

4.1 64D–128D (Local Alignment Drift)#

• instability in early alignment regions
• boundary tearing in transitional surfaces
• inconsistent cross‑model motifs

4.2 256D–512D (Trajectory‑Level Drift)#

• cross‑architecture divergence
• modality‑dependent instability
• inconsistent alignment transitions
• regime‑transition irregularities

4.3 1024D+ (High‑Dimensional Drift)#

• coherence‑surface collapse
• scaling discontinuities
• projection failure
• chaotic divergence

High‑dimensional drift is the most severe and often indicates deep incompatibility.

5. Cross‑Architecture Drift Detection#

Cross‑architecture drift is detected by comparing:

• alignment‑regime maps
• coherence‑surface geometry
• projection stability
• variance distribution
• primitive‑level structure
• resonance‑time behavior

Drift may arise from:

• architectural mismatch
• training‑run divergence
• latent‑dimension changes
• inference‑dynamics differences

vST provides a consistent substrate for evaluating these changes.

6. Cross‑Modality Drift Detection#

Cross‑modality drift occurs when aligning models from different data domains.

Indicators

• divergence in transitional alignment regions
• inconsistent cross‑modality motifs
• modality‑driven oscillations
• non‑invertible projections

Common sources:

• text ↔ image
• protein ↔ structure
• control ↔ simulation
• embedding ↔ generative

7. Drift Severity Levels#

Drift severity is classified into:

Low Severity#

• minor variance shifts
• stable projections
• no regime collapse

Moderate Severity#

• partial fragmentation
• unstable A₂ᴴ transitions
• inconsistent cross‑model alignment

High Severity#

• collapse of coherence surfaces
• persistent A₃ᴴ behavior
• non‑invertible projections
• loss of primitive‑level compatibility

High‑severity drift indicates a failure of alignment invariants.

8. Drift Detection Workflow#

A substrate‑aligned drift detection workflow:

1. Project heterogeneous latent states into 9D
2. Classify alignment regimes (A₁ᴴ, A₂ᴴ, A₃ᴴ)
3. Evaluate scaling continuity (64D–1024D)
4. Check primitive‑level stability (DP, TDP‑X, SP‑X, CP‑X)
5. Validate with vST layers (V₁–V₄)
6. Compare across architectures, modalities, or checkpoints
7. Assign drift category (D₁ᴹ–D₄ᴹ)
8. Assign drift severity (low, moderate, high)

This workflow is architecture‑agnostic and reproducible.

9. Outputs of Multi‑Model Drift Detection#

Drift detection produces:

• drift category (D₁ᴹ–D₄ᴹ)
• drift severity
• alignment‑regime anomalies
• projection‑stability indicators
• scaling‑law discontinuities
• cross‑architecture and cross‑modality alignment surfaces
• vST validation results

These outputs support governance, interpretability, and version management for multi‑model systems. ### vST for Multi‑Model Alignment

Projection of Heterogeneous Latent Spaces and Construction of Cross‑Model Alignment Surfaces#

This document defines how high‑dimensional latent states from different model families are projected into the triadic dimensional cores (3D–9D), and how alignment surfaces are constructed across architectures, modalities, and inference regimes. Projection provides interpretability; alignment surfaces provide comparability. Together, they form the backbone of vST analysis for multi‑model alignment.

1. Purpose of Projection in Multi‑Model Alignment#

Projection enables us to:

• interpret heterogeneous latent spaces through a shared 3D–9D substrate
• identify stable, transitional, and dispersed cross‑model alignment regimes
• map coherence surfaces across architectures and modalities
• compare inference pathways across model families
• detect drift or incompatibility in cross‑model structure
• support vST validation (V₁–V₄)

Cross‑model projection must be architecture‑neutral, invertible, and invariant‑preserving.

2. Projection Overview#

Models may inhabit radically different latent spaces:

• LLMs: 1024D–8192D
• PLMs: 256D–2048D
• Diffusion models: 64D–4096D
• Simulators: structured state‑spaces
• Robotics policies: control‑trajectory manifolds
• Embedding stores: 64D–4096D

The substrate projects all of these into:

Cross‑Architecture Scaling Behavior Across the Dimensional Ladder#

This document defines how multi‑model alignment behaves as dimensionality, model size, modality complexity, and architectural diversity increase. It maps cross‑model scaling laws onto the 3D–1024D dimensional ladder, providing a reproducible, invariant‑preserving framework for understanding how alignment capacity grows, stabilizes, or fragments across heterogeneous systems.

Scaling in multi‑model alignment is not about increasing parameters — it is about increasing compatibility, coherence, and alignment bandwidth across models.

1. Purpose of Multi‑Model Scaling Analysis#

Cross‑model scaling analysis enables us to:

• interpret how alignment capacity expands with model size and modality diversity
• identify stable, transitional, and dispersed scaling regimes
• detect scaling discontinuities across architectures
• evaluate cross‑model compatibility at different dimensional levels
• support vST validation (V₁–V₄)
• project alignment surfaces into 3D–9D cores for interpretability

Scaling is the backbone of cross‑model comparability.

2. Dimensional Ladder for Multi‑Model Alignment#

Cross‑model alignment naturally aligns with the substrate’s dimensional ladder:

• 3D — geometric alignment motifs
• 6D — interaction‑surface alignment
• 9D — coherence‑pathway alignment
• 64D — minimal cross‑model substrate
• 128D — expanded alignment surfaces
• 256D — multi‑primitive cross‑architecture interaction
• 512D — high‑variance cross‑modality regions
• 1024D — full research‑grade alignment substrate

Each step increases alignment bandwidth and structural compatibility.

3. Scaling Primitives for Multi‑Model Alignment#

Scaling behavior is governed by Cross‑Model Scaling Primitives (SP‑X), which ensure:

• invariant‑preserving dimensional expansion
• compatibility between heterogeneous latent spaces
• stable projection into triadic cores
• consistent scaling‑law interpretation across architectures

SP‑X is essential for aligning models with different latent sizes, modalities, or inference dynamics.

4. Scaling Regimes in Multi‑Model Alignment#

4.1 Stable Scaling Regime (S₁ᴹ)#

Characteristics:

• smooth increase in alignment capacity
• stable cross‑model coherence surfaces
• predictable improvements in compatibility
• consistent regime behavior (A₁ᴴ ↔ A₁ᴴ transitions remain bounded)

Occurs in:

• small → medium model comparisons
• similar modalities (e.g., LLM ↔ PLM)
• well‑conditioned cross‑model projections

4.2 Transitional Scaling Regime (S₂ᴹ)#

Characteristics:

• rapid expansion of alignment surfaces
• increased variance across architectures
• branching or oscillatory cross‑model behavior
• sensitivity to modality or architecture differences

Occurs in:

• medium → large model comparisons
• cross‑modality alignment (e.g., text ↔ image)
• cross‑architecture transitions (e.g., diffusion ↔ autoregressive)

4.3 Dispersion Scaling Regime (S₃ᴹ)#

Characteristics:

• fragmentation of alignment surfaces
• unstable or divergent cross‑model mappings
• increased risk of alignment collapse
• non‑invertible projections into 3D–9D cores

Occurs in:

• extremely heterogeneous model pairs
• poorly conditioned cross‑modality mappings
• aggressive scaling or architecture changes

5. Scaling Behavior Across Model Families#

5.1 LLM ↔ PLM#

• high compatibility
• scaling mostly in S₁ᴹ
• stable alignment surfaces

5.2 LLM ↔ Diffusion#

• modality mismatch introduces S₂ᴹ
• alignment depends on projection stability

5.3 Diffusion ↔ Autoregressive Generators#

• different inference dynamics
• transitional scaling dominates (S₂ᴹ)

5.4 Simulators ↔ Robotics Policies#

• strong structural invariants
• scaling often stable (S₁ᴹ → S₂ᴹ)

5.5 Embedding Stores ↔ Generative Models#

• alignment depends on latent‑space conditioning
• scaling oscillates between S₂ᴹ and S₃ᴹ

6. Scaling‑Law Alignment Across Architectures#

Cross‑model scaling follows predictable patterns:

• alignment bandwidth increases with latent dimensionality
• variance increases with modality diversity
• coherence surfaces expand smoothly in S₁ᴹ, sharply in S₂ᴹ, and fragment in S₃ᴹ
• projection stability decreases as architectural heterogeneity increases

The substrate provides a structured way to interpret these patterns.

7. Projection Behavior Under Cross‑Model Scaling#

Projection into triadic cores must remain:

• invertible
• primitive‑aligned
• regime‑aware
• architecture‑neutral
• invariant‑preserving

Scaling affects projection as follows:

• 64D → 9D: stable
• 128D–256D → 9D: transitional
• 512D–1024D → 9D: sensitive, drift‑prone

Projection stability is a key indicator of cross‑model scaling health.

8. Scaling‑Driven Drift in Multi‑Model Alignment#

Scaling can introduce drift through:

• discontinuities in cross‑model latent‑space expansion
• unstable regime transitions
• fragmentation of alignment surfaces
• loss of primitive‑level compatibility

vST validation layers (V₁–V₄) detect these failures.

9. Outputs of Multi‑Model Scaling Analysis#

Scaling analysis produces:

• scaling‑regime classification (S₁ᴹ, S₂ᴹ, S₃ᴹ)
• cross‑model expansion diagnostics
• projection‑stability indicators
• alignment‑regime maps
• drift‑detection signals
• cross‑architecture comparison metrics

These outputs support reproducible, substrate‑aligned evaluation of multi‑model alignment. ### vST for Multi‑Model Alignment

Substrate Definition#

This document defines the substrate used to perform multi‑model alignment within the Validation‑Space‑Time (vST) framework and the 1024D dimensional substrate. It establishes the primitives, alignment invariants, cross‑architecture mapping rules, and projection‑compatible structures required to compare heterogeneous models in a stable, invariant‑preserving manner.

The substrate is architecture‑agnostic and applies to LLMs, PLMs, diffusion models, VAEs, flow models, simulators, robotics policies, embedding stores, and hybrid systems.

1. Purpose of the Multi‑Model Alignment Substrate#

The multi‑model substrate provides a structured, reproducible framework for:

• aligning latent spaces across architectures and modalities
• mapping regime behavior (R₁/R₂/R₃) across heterogeneous inference systems
• comparing scaling behavior across model families
• projecting high‑dimensional states into 3D–9D cores for cross‑model interpretability
• detecting drift across architectures, checkpoints, or training runs
• establishing a unified dimensional grammar for all model types

Multi‑model alignment requires a substrate that is neutral, invertible, and invariant‑preserving across all architectures.

2. Substrate Overview#

The multi‑model substrate models heterogeneous latent spaces using:

• Dimensional Primitives (DP)
• Triadic Dimensional Primitives (TDP)
• Scaling Primitives (SP)
• Coherence Primitives (CP)
• Alignment Primitives (AP)

These primitives define the structure of cross‑model alignment, regime mapping, and projection behavior.

The substrate is anchored by the Triadic Dimensional Cores:

• 3D Structural Core
• 6D Interaction Core
• 9D Coherence Core

and extended through the 1024D high‑dimensional substrate.

3. Alignment Primitives#

3.1 Alignment Primitive (AP)#

The AP is the minimal unit of cross‑model comparability.
It captures:

• local geometric compatibility
• variance‑aligned structure
• regime‑consistent mapping
• projection‑stable correspondence

APs allow two heterogeneous latent states to be compared without requiring architectural similarity.

3.2 Cross‑Architecture TDP (TDP‑X)#

A TDP‑X is a triad of APs that expresses full cross‑model regime behavior.

It captures:

• stable alignment (R₁ ↔ R₁)
• transitional alignment (R₂ ↔ R₂)
• dispersed alignment (R₃ ↔ R₃)

TDP‑X is the backbone of multi‑model regime mapping.

3.3 Cross‑Model Scaling Primitive (SP‑X)#

SP‑X governs dimensional expansion across architectures.

It ensures:

• invariant‑preserving scaling
• compatibility between different latent dimensionalities
• stable projection into triadic cores
• consistent scaling‑law interpretation across models

SP‑X is essential for aligning models with different latent sizes (e.g., 4096D LLM ↔ 1024D diffusion ↔ 256D PLM).

3.4 Cross‑Modality Coherence Primitive (CP‑X)#

CP‑X identifies stable or unstable regions in cross‑model alignment.

It captures:

• coherent alignment regions
• transitional alignment regions
• dispersed or incompatible regions
• cross‑modality regime transitions

CP‑X is essential for drift detection and vST validation.

4. Triadic Dimensional Cores for Multi‑Model Alignment#

4.1 3D Structural Core#

Captures motif‑level geometry shared across models.

Used for:

• cross‑modality motif comparison

• low‑variance structural mapping

4.2 6D Interaction Core#

Captures relational structure across architectures.

Used for:

• cross‑model interaction surfaces
• alignment of transitional regimes
• sampler‑ or decoder‑dependent reorientation

4.3 9D Coherence Core#

Captures pathway‑level coherence across heterogeneous inference systems.

Used for:

• cross‑model coherence mapping
• alignment of inference trajectories
• invertible projection from higher dimensions

The 9D core is the anchor for all cross‑model alignment.

5. High‑Dimensional Substrate (64D–1024D)#

The multi‑model substrate spans the dimensional ladder:

• 64D — minimal cross‑model substrate
• 128D — expanded alignment surfaces
• 256D — multi‑primitive interaction
• 512D — high‑variance cross‑architecture regions
• 1024D — full research‑grade alignment substrate

Each step preserves:

• structural invariants
• resonance‑time invariants
• projection invariants
• alignment invariants
• scaling invariants

This ensures stable alignment across architectures and modalities.

6. Cross‑Model Alignment Structure#

Cross‑model alignment is modeled as:

• sequences of APs
• grouped into TDP‑X
• expanded through SP‑X
• classified using CP‑X

This structure enables:

• regime‑aware alignment
• cross‑modality comparison
• cross‑architecture drift detection
• unified scaling‑law interpretation

7. Projection into Triadic Cores#

High‑dimensional states from different models are projected into:

• 9D for coherence alignment
• 6D for interaction alignment
• 3D for geometric alignment

Projection must remain:

• invertible
• primitive‑aligned
• regime‑aware
• architecture‑neutral
• invariant‑preserving

Projection is essential for cross‑model interpretability.

8. Substrate Outputs#

The multi‑model substrate produces:

• cross‑model regime maps
• alignment surfaces
• scaling‑law diagnostics
• projection‑stability indicators
• drift‑detection signals
• vST validation outputs

These outputs support reproducible, substrate‑level alignment across architectures, modalities, and inference systems. ### vST for Multi‑Model Alignment

Validation‑Space‑Time Layers for Cross‑Architecture and Cross‑Modality Alignment#

This document defines the Validation‑Space‑Time (vST) layers as applied to multi‑model alignment. vST provides a structured, invariant‑preserving framework for evaluating cross‑architecture compatibility, cross‑modality coherence, scaling continuity, and projection stability across the dimensional ladder (3D → 1024D).

The vST layers (V₁–V₄) generalize the substrate‑level validation system to the setting of heterogeneous model families, where latent geometries, inference pathways, and scaling behaviors differ.

1. Purpose of vST for Multi‑Model Alignment#

vST enables reproducible, architecture‑neutral evaluation of:

• structural compatibility across models
• cross‑model regime transitions (A₁ᴴ, A₂ᴴ, A₃ᴴ)
• scaling‑law continuity across architectures and modalities
• projection stability into 3D–9D cores
• cross‑checkpoint and cross‑sampler alignment
• drift detection across model families
• primitive‑level integrity (DP, TDP‑X, SP‑X, CP‑X)

Cross‑model alignment is sensitive to architecture, modality, and dimensionality.
vST ensures these comparisons remain coherent and invariant‑preserving.

2. Overview of vST Layers#

The vST framework consists of four layers:

1. V₁ — Structural Coherence Validation

Example: Alignment Surface Projection Across Architectures (Diffusion ↔ Simulator)#

This example demonstrates how to construct and analyze a cross‑architecture alignment surface between:

• a 1024D diffusion model
• a structured scientific simulator with a 128D state manifold

The goal is to project both systems into the triadic cores (9D → 6D → 3D) and evaluate alignment stability, compatibility, and drift.

1. Scenario Overview#

We assume:

• a diffusion model latent ( z_{\text{Diff}} \in \mathbb{R}^{1024} )
• a simulator state vector ( s_{\text{Sim}} \in \mathbb{R}^{128} )
• both represent the same underlying physical or semantic condition
• cross‑model projection into 9D

2. Step 1 — Project 1024D and 128D into 9D#

Diffusion Model (1024D → 9D)#

Reveals:

• transitional geometry
• sampler‑dependent reorientation
• moderate variance

Simulator (128D → 9D)#

Reveals:

• compact, stable geometry
• strong structural invariants
• low variance

Interpretation#

The simulator provides a stable anchor; the diffusion model provides a transitional pathway.

3. Step 2 — Construct the 9D Alignment Surface#

The alignment surface shows:

• smooth regions where diffusion aligns with simulator invariants
• branching regions where sampler dynamics diverge
• dispersed regions where diffusion enters noise‑dominated phases

This surface is the core artifact for cross‑architecture comparison.

4. Step 3 — Project 9D → 6D#

The 6D interaction projection reveals:

• cross‑step coupling in diffusion
• stable simulator manifold
• transitional alignment regions where the two systems partially overlap

5. Step 4 — Project 6D → 3D#

The 3D structural projection reveals:

• compact motifs for simulator
• oscillatory motifs for diffusion
• partial overlap indicating compatible structure

Interpretation#

The 3D projection exposes motif‑level compatibility and divergence.

6. Step 5 — Drift Detection#

Using vST drift categories:

• D₁ᴹ Structural Drift: low
• D₂ᴹ Dimensional Drift: none
• D₃ᴹ Alignment‑Regime Drift: moderate (A₂ᴴ transitions)
• D₄ᴹ Projection Drift: low

Interpretation#

The systems are partially compatible, with transitional alignment behavior.

7. Summary#

This example demonstrates:

• how to construct cross‑architecture alignment surfaces
• how projection reveals compatibility and divergence
• how drift detection isolates transitional behavior
• how vST ensures invariant‑preserving comparison
  ### vST for Multi‑Model Alignment

Example: Cross‑Model Alignment Regime Map (LLM ↔ Diffusion ↔ PLM)#

This example demonstrates how to construct a cross‑model alignment regime map across three heterogeneous architectures:

• a 4096D Large Language Model (LLM)
• a 1024D diffusion model
• a 256D Protein Language Model (PLM)

The goal is to classify alignment behavior into the triadic alignment regimes:

• A₁ᴴ — stable alignment
• A₂ᴴ — transitional alignment
• A₃ᴴ — dispersed / incompatible alignment

and to visualize how these regimes manifest across dimensional scales.

1. Scenario Overview#

We assume:

• three models with different latent dimensionalities
• a shared semantic or structural anchor (e.g., “binding site description” ↔ “protein structure” ↔ “image prompt”)
• cross‑model latent states extracted from each system
• projection into the 9D coherence core

The example is architecture‑agnostic.

2. Step 1 — Extract Latent States#

Let:

• ( z_{\text{LLM}} \in \mathbb{R}^{4096} )
• ( z_{\text{Diff}} \in \mathbb{R}^{1024} )
• ( z_{\text{PLM}} \in \mathbb{R}^{256} )

represent latent states associated with the same conceptual anchor.

Observed Properties#

• LLM latent: high‑capacity, semantically rich
• Diffusion latent: geometry shaped by noise schedule
• PLM latent: compact, structurally constrained

3. Step 2 — Project All Latents into 9D#

Project each latent into the 9D coherence core.

Reveals#

• LLM: compact, stable geometry → A₁ᴴ
• Diffusion: branching, transitional geometry → A₂ᴴ
• PLM: partially compatible, partially dispersed → A₂ᴴ → A₃ᴴ boundary

Interpretation#

The 9D projection exposes cross‑model compatibility:

• LLM ↔ Diffusion: transitional alignment
• LLM ↔ PLM: stable → transitional
• Diffusion ↔ PLM: transitional → dispersed

4. Step 3 — Construct the Regime Map#

5. Step 4 — Validate with vST Layers#

• V₁: structural coherence preserved for LLM ↔ PLM
• V₂: dimensional continuity intact across all pairs
• V₃: regime transitions substrate‑aligned
• V₄: core alignment stable for LLM ↔ PLM, transitional for others

6. Summary#

This example demonstrates:

• how to classify cross‑model alignment regimes
• how 9D projection reveals compatibility and divergence
• how vST layers validate cross‑architecture behavior
• how regime maps support multi‑model interpretability
