Extend parse_rekey to emit phase1_status / phase1_baseline_passed / phase1_baseline_total fields in signature.json by scraping rekey-test.sh's "Best observed baseline before timeout: N/M passed" line (the timeout path) and "Pre-rekey baseline (all 20 pairs): N/M passed" (the success path). Phase-5-shape parsing is unchanged. Extend mechanism_match_rekey to also fire on the Phase 1 characteristic 12/20 split — the multi-hop-routing-failure shape where direct-peer pairs pass and the four multi-hop pairs (x 2 directions) fail. The Phase 5 predicate remains intact for the pre-existing flake class. Add FIPS_MESH_LAB_NO_RESOURCE_LIMITS=1 to run_rekey_family for unconstrained characterization runs where the goal is to surface a race or scheduling artefact rather than reproduce GHA pressure. Default behaviour (variable unset) keeps the compose-resource-limits.yml overlay engaged. Documented in README.md and the in-script env-var header block.
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 8443) |
| rekey | 5 | UDP | Rekey integration test topology |
tor/ -- Tor Transport Integration
End-to-end Tor transport testing with Docker containers running real Tor daemons. Requires internet access for Tor bootstrapping.
| Scenario | Description |
|---|---|
| socks5-outbound | Outbound SOCKS5 connections through Tor to clearnet peer |
| directory-mode | Inbound via HiddenServiceDir onion service (co-located) |
nat/ -- NAT Traversal Lab
Real Docker NAT traversal tests for the Nostr/STUN bootstrap path,
using router containers with iptables-based NAT, a local Nostr relay,
and a local STUN responder.
| Scenario | Description |
|---|---|
| cone | Two NATed peers establish a UDP traversal path |
| symmetric | UDP traversal fails under symmetric NAT, TCP fallback wins |
| lan | Peers on the same LAN prefer local addresses over reflexive |
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). 20 scenarios covering general stress testing, cost-based parent selection, mixed link technologies (fiber/Bluetooth/WiFi), transport-specific validation (UDP, TCP, Ethernet), and ECN/congestion testing. 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.
interop/ -- Mixed-Version Interop Harness
On-demand harness that runs an N-node full mesh from a node-spec where
each node can run a different build of the FIPS daemon, then attributes
every FMP/FSP/rekey/connectivity failure to a specific version pair
(same-version vs MIXED). Used to catch interop regressions between
builds, not as a per-commit CI gate; not part of ci-local.sh.
mesh-lab/ -- Mesh Reliability Lab
On-demand harness that runs a chosen integration suite N times under a
configurable host-pressure profile (idle / light / github-runner-
equivalent / heavy via stress-ng), per-container netem impairment,
and optional trace-level RUST_LOG, capturing per-rep diagnostics and a
mechanism-match summary across the run. Used for statistical reliability
characterization of known flake classes under calibrated stress, not as
a per-commit gate; not part of ci-local.sh.
