# RTT/1 — Structural Critique
**Engine:** RTT/1 Structural  
**Mode:** S‑mode (structural synthesis)  
**Session:** rtt=1 · coherence=declared · drift=bounded · paradox=structural  

The structural critique is the **synthesis layer** of RTT/1.  
It combines:

- the clarity surface  
- load‑bearing detection  
- contradiction scan  

into a **single structural reading** of the input.

RTT/1 does **not** interpret meaning.  
It evaluates **structure only**.

---

## 1. Structural Presence
Elements that are **structurally present**, meaning they appear consistently and support the input’s shape.

**Template:**
- Presence A: {element}  
- Presence B: {element}  
- Presence C: {element}  

Presence is determined by:

- recurrence  
- anchoring  
- dependency  
- propagation  

---

## 2. Structural Absence
Elements that the structure **appears to require** but are missing.

**Template:**
- Absence A: {missing element}  
- Absence B: {missing element}  

Absence is detected when:

- a load‑bearing element has no support  
- a contradiction implies a missing link  
- a structural anchor lacks definition  

---

## 3. Structural Tension
Misalignments between structural layers.

**Template:**
- Tension A: {element vs element}  
- Tension B: {goal vs constraint}  

Tension is **not** a contradiction.  
It is a **misalignment** that may become a contradiction downstream.

---

## 4. Structural Stability
Assessment of whether the structure holds together under RTT/1 criteria.

**Template:**
- Stability: stable / semi‑stable / unstable  
- Reason: {explanation}  

Stability is based on:

- load‑bearing coherence  
- contradiction geometry  
- anchor propagation  

---

## 5. Structural Shape
RTT/1 classifies structural shape as:

- **Linear** — sequential dependency chain  
- **Layered** — stacked conceptual layers  
- **Radial** — central anchor with outward dependencies  
- **Hybrid** — mixture of shapes  

**Template:**
- Shape: {linear / layered / radial / hybrid}  
- Anchors: {elements}  
- Dependencies: {elements}  

---

## 6. Structural Synthesis
This is the **core output** of RTT/1.

It combines:

- presence  
- absence  
- tension  
- stability  
- shape  

into a single structural reading.

**Template:**
- The structure appears to rely on {elements}.  
- It maintains coherence through {anchors}.  
- It exhibits tension between {elements}.  
- Stability is {assessment}.  
- The overall shape is {shape}.  

---

## 7. Structural Questions (Non‑interpretive)
Questions raised by the structure itself.

**Template:**
- What structural role does {element} serve?  
- How does {element} propagate?  
- What stabilizes the tension between {A} and {B}?
