From 863be6780a3219e1a048adea7eff64dbf5923c0c Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Sat, 9 May 2026 11:27:38 +0000 Subject: [PATCH 1/7] fix(a2a): validate session_id at entry of _handle_session_close before devcontainer cleanup The _handle_session_close handler in the A2A local facade previously validated session_id only after checking whether a session service was wired. When no session service was available, _cleanup_session_devcontainers() was invoked with an empty or missing session_id, risking incorrect container lifecycle operations on unknown sessions. This fix moves validation to the top of _handle_session_close so it applies uniformly across both code paths. Updated BDD tests in features/a2a_facade_wiring.feature and features/a2a_facade_coverage.feature to reflect the new validation behavior.
