From 69b9232acf5afe56140804e3d87801f976dbabb6 Mon Sep 17 00:00:00 2001 From: Jobdori Date: Sat, 4 Apr 2026 17:05:03 +0900 Subject: [PATCH] test(runtime): add cross-module integration tests (P1.2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add integration_tests.rs with 11 tests covering: - stale_branch + policy_engine: stale detection flows into policy, fresh branches don't trigger stale rules, end-to-end stale lane merge-forward action - green_contract + policy_engine: satisfied/unsatisfied contract evaluation, green level comparison for merge decisions - reconciliation + policy_engine: reconciled lanes match reconcile condition, reconciled context has correct defaults, non-reconciled lanes don't trigger reconcile rules - stale_branch module: apply_policy generates correct actions for rebase, merge-forward, warn-only, and fresh noop cases These tests verify that adjacent modules actually connect correctly — catching wiring gaps that unit tests miss.
