Artan fencing belirteçleri, kalp atışı kira (lease) tazelemesi ve gRPC izleme akışları uygulayan hata-toleranslı dağıtık kilit ve koordinasyon sistemi.

### 3 Olgunluk Seviyesi Yapılandırması

#### 1. Initial Target: 2,500 lock ops/sec

- **Garantiler**: Lease TTL Auto-Revocation
- **Altyapı Topolojisi**: 3-node shared etcd cluster.
- **Operasyonel Ödünleşim**: Shared cluster can suffer contention from background watch queries.

#### 2. Scaled Target: 20,000 lock ops/sec

- **Garantiler**: Strict Monotonic Fencing Tokens + Storage Gate Validation
- **Altyapı Topolojisi**: 5-node dedicated NVMe cluster isolated from application databases.
- **Operasyonel Ödünleşim**: Requires client libraries to propagate and validate fencing tokens at storage level.

#### 3. Ultra-Scale Target: 150,000 lock ops/sec

- **Garantiler**: Hierarchical Leases with Local In-Memory Pre-Fencing
- **Altyapı Topolojisi**: 7-node multi-datacenter cluster with dedicated optical cross-connects.
- **Operasyonel Ödünleşim**: High hardware and private fiber network infrastructure costs.

### Ele Alınan Hata Modları

- `DS-FAIL-01: Split-Brain Partitioning`
- `DS-FAIL-17: Zombie Leader Fencing Bypass`
