# TANRAIL ONE — Phase 3.2.2 Final Gate

## Inspection Date: 2026-09-04
**Target:** Phase 3.2.2 Inventory Core Data Foundation

### IMPLEMENTATION STATUS
PASS

### TEST STATUS
37 tests / 37 passed / 0 failed

### SECURITY STATUS
PASS (Strict Context Isolation achieved via `InventoryScope`)

### ARCHITECTURE COMPLIANCE
PASS

### NEGATIVE STOCK POLICY
STRICT REJECTION — IMPLEMENTED (At Database Transaction level)

### REGRESSION STATUS
PASS

### REMAINING RISKS
No immediate risks. Advanced concurrency under extreme heavy load (thousands of transactions per second on the exact same location/item) will queue due to pessimistic locking, which is the mathematically correct and desired behavior to prevent data corruption.

## VERDICT: READY FOR PHASE 3.2.3
