From 695ef57017ab97f0efb54d4aafd955623ff7cd5d Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Sun, 19 Apr 2026 02:00:13 +0000 Subject: [PATCH] refactor: rename all ACP module imports to A2A per ADR-047 - Add comprehensive BDD feature file for A2A module imports audit - Implement step definitions for A2A module verification - Verify A2A module structure and exports - Ensure no ACP imports exist in source code - Validate A2A integration with application container - Test A2A clients, errors, models, facade, versioning, transport, and events - Verify documentation references are properly updated - Confirm .gitignore marks ACP as deprecated This audit ensures complete migration from ACP to A2A per ADR-047 standard adoption. --- features/a2a_module_imports_audit.feature | 136 +++++
