* MODEL GUARDIAN - CRITICAL PATH
|

*
|
||||
* THIS IS THE MOST CRITICAL COMPONENT OF BRAINY
|
||||
* Without the exact model, users CANNOT access their data
|
||||
*
|
||||
* Requirements:
|
||||
* 1. Model MUST be Xenova/all-MiniLM-L6-v2 (never changes)
|
||||
* 2. Model MUST be available at runtime
|
||||
* 3. Model MUST produce consistent 384-dim embeddings
|
||||
* 4. System MUST fail fast if model unavailable in production
