From e0aae73cf4238281326dccfb1b44e637cbbd5b87 Mon Sep 17 00:00:00 2001 From: Jeremie Fraeys Date: Mon, 23 Feb 2026 20:26:01 -0500 Subject: [PATCH] test(phase-7-9): audit verification, fault injection, integration tests Implement V.7, V.9, and integration test requirements: Audit Verification (V.7): - TestAuditVerificationJob: Chain verification and tamper detection Fault Injection (V.9): - TestNVMLUnavailableProvenanceFail, TestManifestWritePartialFailure - TestRedisUnavailableQueueBehavior, TestAuditLogUnavailableHaltsJob - TestConfigHashFailureProvenanceClosed, TestDiskFullDuringArtifactScan Integration Tests: - TestCrossTenantIsolation: Filesystem isolation verification - TestRunManifestReproducibility: Cross-run reproducibility - TestAuditLogPHIRedaction:
