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
