Goal: Switch the system into a strict, template-driven manual examination mode when low vision confidence values align with a lack of reference data
Interaction: User-to-System
Stimulus: The workspace detects a critical double-blind failure criteria match during the case evaluation phase
SysResponse: Disables automated diagnostic suggestions entirely and forces a standardized manual morphology review
Title [Verb + Noun]: Activate Clinical Investigation Mode
UC-ID: UC-35956
VerboseForm: The use case 'Activate Clinical Investigation Mode' defines a User-to-System interaction where the UP5 aims to Switch the system into a strict, template-driven manual examination mode when low vision confidence values align with a lack of reference data. This workflow is triggered when The workspace detects a critical double-blind failure criteria match during the case evaluation phase, causing the system to respond by providing Disables automated diagnostic suggestions entirely and forces a standardized manual morphology review.

# Use Case Deep-Dive: Activate Clinical Investigation Mode

## 1. Structural Preconditions & Postconditions
* **Preconditions:**
  * System classification loops return low-confidence indices.
  * Authoritative RAG reference lookups return no matches, indicating an unmapped anatomical variant or a severe image anomaly.
* **Postconditions (Success State):**
  * Automated suggestions are masked out to prevent cognitive bias.
  * Mandatory manual template verification frameworks are deployed into active workspace view.

## 2. Interaction Scenarios (Step-by-Step Flow)

### Main Success Scenario (Happy Path)
1. **System** monitors deep-learning inference score bounds during case evaluation.
2. **System** runs background reference data lookups and catches a dual failure state (Low confidence + Empty knowledge reference).
3. **System** drops the standard review interface layout to prevent automated suggestion bias or human misinterpretation loops.
4. **System** changes UI display focus markers to activate an explicit, template-driven investigation layout.
5. **System** includes `UC_Q4_Annotate` to force manual measurement entries.
