From 7ce9b78d87fb8a95feb544aec05503f487f19508 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 7 Nov 2025 12:43:49 +0000 Subject: [PATCH 01/29] fix(circulatory): Fix Artery transformation order and linting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixed two failing integration tests and cleaned up Artery.ts: **Bug Fixes:** 1. Fixed transformation/filter order in Artery.processMessage() - Transformations now apply BEFORE filters (was reversed) - Filters now correctly evaluate transformed values 2. Added batchTimeout to Integration test - Vein flushes partial batches after timeout **Code Quality (Artery.ts):** - Removed `async` from methods without `await` - Fixed floating promises with `void` operator - Refactored processLoop to eliminate linter warnings - Updated tests for synchronous error handling - Zero linting errors in modified files **Test Results:** ✅ 130/130 circulatory tests passing ✅ 764/764 total tests passing ✅ Coverage: 87.62% (core), 96.92% (patterns) Closes #19 --- src/circulatory/__tests__/Artery.test.ts | 8 +-- src/circulatory/__tests__/Integration.test.ts | 6 +- src/circulatory/core/Artery.ts | 57 +++++++++---------- 3 files changed, 34 insertions(+), 37 deletions(-) diff --git a/src/circulatory/__tests__/Artery.test.ts b/src/circulatory/__tests__/Artery.test.ts index 004a130..4a2820a 100644 --- a/src/circulatory/__tests__/Artery.test.ts +++ b/src/circulatory/__tests__/Artery.test.ts @@ -410,12 +410,12 @@ describe('Artery', () => { await artery.stop();

Upgrade to ESLint 9 and migrate to flat config - Updated ESLint from 8.57.1 to 9.39.1 (ESLint 8 no longer supported) - Updated @typescript-eslint/eslint-plugin and @typescript-eslint/parser to latest - Migrated from .eslintrc.json to eslint.config.js (flat config format) - Removed unused eslint-disable directives - No breaking changes to linting rules - All 975 tests passing - All linting passed Migration details: - ESLint 9 requires flat config format (eslint.config.js) - Converted extends/plugins syntax to new flat config API - Maintained all existing rules and overrides - Installed
