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

# Cost-Based Parent Selection: Mixed Technology 7-Node Test

# Topology (explicit, multiple link types):
|
|
#
|
|
# n01 (root)
|
|
# / | \
|
|
# fiber | fiber BT
|
|
# / | \
|
|
# n02 n03 n04
|
|
# | | \ |
|
|
# fiber fiber \ fiber
|
|
# | | wifi |
|
|
# n05 n06 n07
|
|
#
|
|
# Cross-links: n03-n05 (fiber), n04-n06 (wifi)
|
|
#
|
|
# Test subjects:
|
|
# - n06 has edges to n03 (fiber) and n04 (wifi) — should prefer n03
|
|
# - n04's link to root is Bluetooth (L2CAP), so n04 has higher-cost parent link
|
|
# - n07 connects only to n04 (no choice, stuck with Bluetooth upstream)
|
|
#
|
|
# Validation: tree snapshot shows n06's parent is n03 (not n04).
