Three infrastructure bugs fixed: - DNS resolution never populated the identity cache because Docker overwrites /etc/resolv.conf at container start. Fix: bind-mount resolv.conf in the chaos compose template, matching the static and sidecar test configs. - Traffic generator used config-time npubs for iperf3 targets, but ephemeral nodes generate fresh keypairs at startup. Fix: share the peer churn manager's runtime npub cache with the traffic manager. - Log analysis had no discovery counters and used wrong patterns. Fix: add discovery section with correct log message matching. Also adds timestamped output directories (YYYYMMDD-HHMMSS-scenario), coord_ttl_secs override in maelstrom.yaml, FIPS_SIM_OUTPUT env var support, and maelstrom-sparse scenario for sparse topology testing.

# Maelstrom-sparse: sparse geometric topology for discovery stress testing
|
|
#
|
|
# Uses random geometric graph with low radius to produce sparse connectivity
|
|
# (~3-4 peers per node), forcing multi-hop routing and heavy discovery usage.
|
|
# The short coord cache TTL (10s) ensures transit-warmed entries expire
|
|
# quickly, requiring rediscovery.
|
|
#
|
|
# Default: 50 nodes. Override with --nodes flag.
