Chaos harness enhancements: - transport_mix config: weighted random transport assignment for random topologies (erdos_renyi, random_geometric) with UDP/Ethernet/TCP - Replace LoRa with Bluetooth L2CAP in cost-based/mixed-tech scenarios using realistic netem values (15-40ms delay, 5-15ms jitter, 2-8% loss) - New churn-20-mixed scenario: 20-node Erdos-Renyi with 60% UDP, 20% Ethernet, 20% TCP, full netem/link-flap/churn/bandwidth config - Expanded chaos README with full scenario catalog in four categories Static harness: - Updated README with topology table and scenario count

FIPS Testing
Integration and simulation test harnesses for FIPS, using Docker containers running the full protocol stack.
Test Harnesses
static/ -- Static Docker Network
Fixed topologies with manual scripts for building, config generation, connectivity tests (ping, iperf), and network impairment (netem). Useful for deterministic debugging and validating specific topology configurations.
| Topology | Nodes | Transport | Description |
|---|---|---|---|
| mesh | 5 | UDP | Sparse mesh, 6 links, multi-hop |
| chain | 5 | UDP | Linear chain, max 4-hop paths |
| mesh-public | 5+1 | UDP | Mesh with external public node |
| tcp-chain | 3 | TCP | Linear chain over TCP (port 443) |
chaos/ -- Stochastic Simulation
Automated network testing with configurable node counts, topology algorithms (random geometric, Erdos-Renyi, chain, explicit), and fault injection (netem mutation, link flaps, traffic generation, node churn). 16 scenarios covering general stress testing, cost-based parent selection, mixed link technologies (fiber/Bluetooth/WiFi), and transport-specific validation (UDP, TCP, Ethernet). Scenarios are defined in YAML and executed via a Python harness that manages the full lifecycle: topology generation, Docker orchestration, fault scheduling, log collection, and analysis.
