Issue #5: Feature Flags Not Implemented

Severity: MEDIUM Priority: P1 Component: Core/Configuration Assignee: TBD Estimated Effort: 4 hours

Description: Feature flags for gradual rollout of Phase 1 features have not been implemented in FleetConfig.

Expected Changes:

interface FleetConfig {
  features?: {
    multiModelRouter?: boolean;  // Default: false
    streaming?: boolean;          // Default: false
  };
}

Acceptance Criteria:

• Feature flags in FleetConfig
• Default values (off) preserve backward compatibility
• Can enable/disable at runtime
• Configuration migration automatic
• Tests validate flag behavior
• Documentation explains flags

Dependencies: Issue #1, Issue #2

Blocked By: None (can implement independently)

Blocks: Gradual rollout strategy

🟢 LOW PRIORITY (Nice to Have)

Issue #6: Performance Benchmarks Not Established

Severity: LOW Priority: P2 Component: Testing/Performance Assignee: TBD Estimated Effort: 8 hours

Description: Performance benchmarks for Phase 1 features do not exist to validate targets.

Required Benchmarks:

• Model selection speed (<10ms target)
• Cost calculation accuracy (±5% target)
• Streaming latency (<100ms target)
• Memory usage during streaming
• Throughput with vs without router

Acceptance Criteria:

• Benchmark suite created
• Baseline established
• Targets validated
• CI/CD integration
• Performance regression alerts
• Results documented

Dependencies: Issue #1, Issue #2

Blocked By: Issue #1, Issue #2

Blocks: Performance optimization
