From 7b5c157b1217d98b98d9a93c02ec601cbbf9a055 Mon Sep 17 00:00:00 2001 From: Christian Gick Date: Sun, 29 Mar 2026 08:32:48 +0300 Subject: [PATCH] fix(MAT-258): blacklist unverified E2EE devices + add CI tests Unverified devices (lacking cross-signing) caused OlmUnverifiedDeviceError in _send_text(), silently breaking all message delivery. Now on_sync() blacklists non-cross-signed devices instead of skipping them, and _send_text() catches E2EE errors gracefully. Adds 12 unit tests for device trust policy and send error handling. CI test job now gates deployment in deploy.yml.
