EN-029: Simulation mode

Phase: 4 -- Advanced (v3.0.0)
Dependencies: Phase 2 complete
Design Doc: 24-ensemble-network.md -- Section 13

Description

Implement simulation tooling for modeling network behavior with simulated LLMs, time compression, and scenario definitions.

Acceptance Criteria

• Simulation builder: network, scenario, chatModel, timeCompression
• Scenario builder: load profiles, failure profiles, latency profiles per ensemble
• SimulationChatModel.fast() -- deterministic, fast, configurable response characteristics
• LoadProfile: steady, ramp, spike
• FailureProfile: downAt(time, duration)
• LatencyProfile: fixed, multiply
• SimulationResult: bottlenecks, failure cascades, capacity report, token estimate
• Time compression (1 hour = 1 minute)

Tests

• Unit tests for scenario construction
• Unit test: LoadProfile ramp generates correct request rate
• Unit test: FailureProfile kills and restores at correct times
• Unit test: time compression factor applied correctly
• Integration test: simulate peak load, verify capacity report
