From 735e15cb2c560a552acc7519c819d7b0fab10f39 Mon Sep 17 00:00:00 2001 From: igneum-labs <337424239+igneum-labs@users.noreply.github.com> Date: Sat, 3 Oct 2026 22:17:37 +0000 Subject: [PATCH] Harness: consensus attack catalogue runner and first results tools/harness runs the standard consensus-attack catalogue against a private test network of our own igneumd nodes (127.0.0.1 ports 27200+, /tmp/igneum-harness, never the live devnet or the PC node), with a pass criterion per scenario from the spec and a measured result each. Built on the node fork's own crates (igneum-harness-sim on kaspa_utils::sim as simpa does; igneum-p2p-probe for the wire). Scenarios: 1 withholding, 2 timestamp edges and drift, 3 partition and heal, 4 eclipse, 5 malformed and boundary inputs on every p2p and RPC surface, 6 resource exhaustion, 7 fast-miner flood. Finality and difficulty-controller scenarios are stubs with their criteria written. bench-log: one dated entry, a row per scenario (criterion, measured, pass or fail). First run: 19 of 20 measured rows pass. Findings recorded in the entry: scenario 5 reproduces ledger M15 on HEAD (bogus past-day or DAA headers build a 256 MiB cache before rejection; the r3-fixes branch removes it); scenario 1 at 45% hash with burst withholding shows a selfish-mining blue-share gain (50.7% of blues), the one failing row.
