## Critical Blockers
### P0 - MUST FIX BEFORE BETA
#### 🔴 CRITICAL: Security Hardening
**Problem:** Finalize API Key storage migration
**Impact:** Security best practices compliance
**Solution:** Move all remaining keys to secure BuildConfig/Keystore
**Implementation:**
```kotlin
// Target architecture:
private val API_KEY = BuildConfig.SERVICE_API_KEY
// In local.properties:
SERVICE_API_KEY=your_secure_key_here
// In build.gradle.kts:
buildConfigField("String", "SERVICE_API_KEY", "\"${properties["SERVICE_API_KEY"]}\"")
```
---
### P1 - HIGH PRIORITY (1-3 weeks)
#### 🟠 ONNX Embeddings Stub (2-3 weeks)
