## ADDED Requirements

### Requirement: Cache Telemetry SHALL Include Memory Amplification Signals
Operational telemetry MUST expose cache domain memory usage indicators and representation amplification factors.

#### Scenario: Deep health telemetry request
- **WHEN** operators inspect cache telemetry
- **THEN** telemetry MUST include per-domain memory footprint and amplification indicators sufficient to detect redundant structures

### Requirement: Efficiency Benchmarks SHALL Gate Cache Refactor Rollout
Cache/query efficiency changes MUST be validated against baseline latency and memory benchmarks before rollout.

#### Scenario: Pre-release validation
- **WHEN** cache refactor changes are prepared for deployment
- **THEN** benchmark results MUST demonstrate no regression beyond configured thresholds for P95 latency and memory usage
