charset=UTF-8 Content-Transfer-Encoding: 8bit Added new scenario generator method that creates truly balanced traffic patterns by pairing each A→B transfer with a corresponding B→A transfer of the same amount.

From 218a9eb96c210e1ef65d23d9256d7a789dfd5d99 Mon Sep 17 00:00:00 2001 From: nambrot Date: Tue, 27 Jan 2026 20:20:30 -0500 Subject: [PATCH 07/54] chore(rebalancer-sim): Regenerate scenarios with new format and balanced traffic - Updated all scenarios with embedded default configs and expectations - balanced-bidirectional now uses balancedTraffic generator for true balance - Added random-with-headroom scenario: random traffic with sufficient collateral Scenarios now self-contained with timing, bridge config, strategy config, and expected KPI assertions.

[PATCH 08/54] test(rebalancer-sim): Update tests to use scenario defaults and expectations - full-simulation tests now load defaults from scenario JSON files - Added dynamic strategy config wiring with deployed bridge addresses - Tests assert expectations from scenario files (minCompletionRate, etc.) - random-with-headroom test checks p50 latency < 500ms for headroom validation - Results saved to results/ directory for post-hoc analysis Co-Authored-By: Claude Opus 4.5 --- .../test/integration/deployment.test.ts | 120 +++--- .../test/integration/full-simulation.test.ts | 366

With multiple provider instances pointing to the same anvil RPC, this caused significant contention and 3-4 second delays for some transfers. Changes: - Disable polling on all JsonRpcProvider instances - Create and pass pre-configured MultiProtocolProvider with polling disabled to RebalancerService - Add cleanup for MultiProtocolProvider in RealRebalancerRunner Result: p95 latency dropped from ~4000ms to ~400-1000ms depending on scenario. Both rebalancers now show comparable performance.

Mon Sep 17 00:00:00 2001 From: nambrot Date: Fri, 30 Jan 2026 13:59:21 -0500 Subject: [PATCH 41/54] refactor(rebalancer-sim): Flatten directory structure and consolidate types MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses paulbalaji's PR review feedback on over-engineered structure: - Flatten single-file directories to src root - Consolidate 6 types.ts files into single src/types.ts (~800 lines) - Create runners/ directory for rebalancer implementations - Keep visualizer/ directory (has multiple related files) - Replace `export *` with explicit exports in index.ts - Update all imports across source and test files New structure: ``` src/ ├── BridgeMockController.ts ├── KPICollector.ts ├── MessageTracker.ts ├──
