# **DSLO v0.8 — Context Geometry Surface**  
**Version:** 0.8  
**DOI:** 10.5281/zenodo.22180700  
**Surface Class:** Context Geometry  
**Meta‑Class:** Cross‑Domain (M1–M5)

## **1. Purpose of This Surface**
The **Context Geometry Surface** defines the geometric primitives used to model **context**, **context‑shift**, **context‑alignment**, and **context‑stability** across biological, cultural, machine, economic, and abstract systems.

It is one of the twelve lawful geometry surfaces included in the **DSLO v0.8 Federated Geometry Expansion**.

This surface is:

- **strictly additive**  
- **geometry‑only**  
- **substrate‑derived**  
- **invariant‑preserving**  
- **non‑runtime**  
- **non‑agentic**  
- **public‑layer safe**  

It introduces **no physics**, **no substrate‑skin**, **no Umbrella 12**, and **no v0.9 references**.

---

## **2. Scientific Role**
The Context Geometry Surface provides the geometric vocabulary required to model:

### **Context Stability**
How systems maintain lawful behavior under changing conditions.

### **Context Shift Geometry**
How context transitions occur without violating invariants.

### **Context Alignment Geometry**
How multiple agents or domains align context to maintain coherence.

### **Context Drift Channels**
How context drifts under load, signal change, or environmental variation.

### **Context Identity Geometry**
How identity is preserved across context transitions.

These primitives support:

- federated thermodynamic ecology  
- multi‑agent context alignment  
- lawful drift propagation  
- invariant‑preserving transitions  
- cross‑domain interoperability

## **3. Lineage**
This surface inherits **exclusively** from the DSLO v0.7 substrate and manifold suite.

From the DSLO v0.7 Geometry Layer declaration:

> “DSLO v0.7 establishes a closed, lawful geometry layer spanning biological, cultural, machine, economic, and abstract systems.”

And:

> “Properties: substrate_neutral, invariant_preserving, lawful, non_reconstructible, public_layer_safe.”

The v0.5 finance substrate also demonstrates lawful cross‑domain geometry:

> “identity_preserved: boolean”  
> “manifold_legal: boolean”

These excerpts show DSLO’s lawful substrate‑neutral geometry and its cross‑domain applicability — the same principles used in the v0.8 context surface.

## **4. Geometry Primitives**
The Context Geometry Surface defines the following lawful primitives:

### **CX1 — Context Stability Envelope**
Stability envelopes for context across all DSLO domains.

### **CX2 — Context Shift Geometry**
Lawful geometric transitions between context states.

### **CX3 — Context Alignment Geometry**
Geometric structures for aligning context across multi‑agent and multi‑domain systems.

### **CX4 — Context Drift Channels**
Lawful drift channels for context under load, signal change, or environmental variation.

### **CX5 — Context Identity Geometry**
Identity‑preserving context structures across biological, cultural, machine, economic, and abstract systems.

---

## **5. Invariant Families**
This surface stabilizes the following invariant families:

### **IF‑C1 — Context Stability Invariants**
Ensure stability across context transitions and alignment geometry.

### **IF‑C2 — Context Continuity Invariants**
Ensure continuity across context drift channels and stability envelopes.

### **IF‑C3 — Context Identity Invariants**
Ensure identity preservation across context shifts and alignment geometry.

---

## **6. Continuity Bands**
The surface defines two continuity bands:

### **CB‑C1 — Context Continuity Band**
Ensures lawful continuity across context stability and drift geometry.

### **CB‑C2 — Alignment Continuity Band**
Ensures continuity across context alignment geometry.

---

## **7. Alignment Targets**
This surface aligns with:

- geometry surfaces  
- domain surfaces  
- invariant surfaces  
- mapping surfaces  
- registry surfaces  
- ecology geometry  
- federated geometry  

It does **not** introduce runtime behavior or agentic transitions.

---

## **8. Legality & Posture**
This surface follows all v0.8 legality constraints:

- geometry‑only  
- strictly additive  
- substrate‑derived  
- invariant‑preserving  
- non‑runtime  
- non‑agentic  
- public‑layer safe  
- no references to v0.9  
- no references to physics or substrate‑skin  
- no references to Umbrella 12  
- no references to sibling v0.8 artifacts  

---

## **9. Continuity Statement**
The Context Geometry Surface:

- inherits exclusively from DSLO v0.7  
- extends geometry only  
- preserves all invariants  
- introduces no substrate modifications  
- remains fully lawful under DSLO v0.8  
- provides context geometry for federated thermodynamic modeling
