Follow these steps:

### 1. Identify the synthesis

Target: the synthesis or conclusion in the current context.

### 2. Map the load-bearing claims

Which assertions does the synthesis depend on? What would break if any proved false? Which claims support multiple parts of the conclusion?

### 3. Check for dropped inputs

Does each original perspective or piece of evidence appear? Was anything dismissed rather than integrated, or simplified to the point of distortion?

### 4. Test for internal contradictions

Does any part contradict another? Does the unified view require believing incompatible things? Does resolving one tension create new ones?

### 5. Challenge from multiple angles

What would a skeptic question? What would someone in each original position object to? Where would a domain expert find gaps?

### 6. Verify structural integrity

Does removing one piece cause collapse? Does it depend on unvalidated assumptions? Does the organizing principle actually unify what it claims to?

### 7. Identify brittleness

What new evidence would invalidate it? Which assumptions are least tested? Where is it strongest versus most vulnerable?

### 8. Render verdict

State whether the synthesis passes or fails the coherence test, with specific reasons and any caveats.
