# Detection Lab — Instructor Edition  
### Structural Detection Module • RTT/1  
### Instructor Guidance for Teaching Structure-First Detection
 
---
 
## 1. Purpose of This Lab
 
This lab trains students to detect **structure**, not content.
 
Your role as instructor is to:
 
- guide attention  
- reinforce structural heuristics  
- prevent interpretation  
- prevent conclusion‑making  
- maintain zero drift  
- evaluate detection packets for structural accuracy  
 
Students must never be told:
 
- what they are detecting  
- what the structure “means”  
- what conclusion to reach  
 
Your job is to teach **how detection works**, not what to detect.

## 2. Learning Outcomes
 
By the end of this lab, students should be able to:
 
- identify structural motifs  
- detect boundaries and transitions  
- recognize invariants  
- sense drift and deformation  
- identify regime signals  
- evaluate coherence  
- produce a complete Detection Packet  
 
They should *not* be able to:
 
- interpret content  
- diagnose meaning  
- infer purpose  
- guess the target  
 
If they attempt to interpret, redirect them to structure.

## 3. Lab Materials
 
You will need:
 
- 3–5 structural samples (text, code, JSON, logs, schemas)  
- the Detection Primer  
- the Detection Packet template  
- the Heuristic Suite  
- the five operators (Detection, Drift Sense, Regime Awareness, Continuity Compass, Triangulation)  
 
Samples must be:
 
- domain‑neutral  
- content‑safe  
- structurally interesting  
- varied in density, symmetry, and drift

## 4. Lab Flow (Instructor Protocol)
 
### **Step 1 — Cold Scan (No Guidance)**  
Students examine the sample silently for 60–90 seconds.  
They write down:
 
- what repeats  
- what changes  
- what feels stable  
- what feels broken  
 
Do not answer questions.  
Do not explain structure.  
Do not hint at meaning.
 
---
 
### **Step 2 — Heuristic Activation**  
Introduce 3–5 heuristics:
 
- Repetition  
- Boundary  
- Invariant  
- Deformation  
- Coherence  
 
Ask students to re‑scan the sample using only these heuristics.
 
---
 
### **Step 3 — Structural Marking**  
Students mark:
 
- motifs  
- boundaries  
- invariants  
- anomalies  
- regime hints  
 
Instructor checks for:
 
- over‑interpretation  
- semantic drift  
- premature conclusions  
 
Redirect with:  
**“Describe the structure, not the meaning.”**
 
---
 
### **Step 4 — Detection Packet Construction**  
Students fill out:
 
- motifs_detected  
- boundaries  
- invariants  
- anomalies  
- regime_hints  
- confidence  
- notes  
 
Instructor checks for:
 
- structural accuracy  
- heuristic alignment  
- absence of interpretation  
- clarity of boundaries  
- correct identification of invariants  
 
---
 
### **Step 5 — Drift Sense Checkpoint**  
Ask students:
 
- Where does the structure bend?  
- Where does the rhythm break?  
- Where does the density shift?  
 
Instructor evaluates:
 
- drift detection accuracy  
- ability to distinguish noise from deformation  
 
---
 
### **Step 6 — Regime Awareness Checkpoint**  
Ask students:
 
- Does the structure feel formal, emergent, chaotic, or hybrid?  
- What signals support that?  
 
Instructor checks:
 
- regime reasoning is structural, not semantic  
- no domain assumptions  
- no content interpretation  
 
---
 
### **Step 7 — Triangulation**  
Students combine:
 
- motifs  
- invariants  
- drift signals  
- regime hints  
 
Instructor checks:
 
- triangulation is structural  
- no leaps to meaning  
- no narrative construction  
 
---
 
## 5. Evaluation Rubric
 
### **A. Structural Accuracy (40%)**  
Correct identification of:
 
- motifs  
- boundaries  
- invariants  
- anomalies  
 
### **B. Heuristic Application (25%)**  
Proper use of:
 
- repetition  
- boundary  
- invariant  
- deformation  
- coherence  
 
### **C. Drift & Regime Awareness (20%)**  
Ability to detect:
 
- drift signatures  
- regime signals  
 
### **D. Zero Interpretation (15%)**  
No:
 
- meaning  
- diagnosis  
- conclusion  
- narrative  
 
Interpretation = automatic deduction.

## 6. Instructor Redirection Phrases
 
Use these when students drift into meaning:
 
- “Stay with the structure.”  
- “Describe what you see, not what it means.”  
- “Focus on the pattern, not the story.”  
- “Interpretation is downstream — detection is upstream.”  
- “Return to the heuristics.”  
 
These phrases maintain structural discipline.

## 7. Common Student Errors
 
### **Error 1 — Interpretation**  
Fix: Redirect to structure.
 
### **Error 2 — Overfitting**  
Fix: Emphasize invariants.
 
### **Error 3 — Missing Drift**  
Fix: Highlight deformation heuristic.
 
### **Error 4 — Confusing Noise with Structure**  
Fix: Use density + coherence heuristics.
 
### **Error 5 — Premature Regime Assignment**  
Fix: Require multiple supporting signals.

## 8. Instructor Notes
 
- Never reveal the target.  
- Never confirm or deny student guesses.  
- Never imply meaning.  
- Maintain structural neutrality.  
- Reinforce heuristics constantly.  
- Reward clarity, not correctness.  
 
The goal is **structural literacy**, not discovery.

## 9. Completion Criteria
 
A student has mastered this lab when they can:
 
- detect structure in any sample  
- identify drift and invariants  
- sense regime without interpreting  
- produce a clean Detection Packet  
- maintain zero semantic drift  
 
This is the foundation of all higher‑order detection work.
