A2A Linker v1.4.0 strengthens unattended listener safety and fixes session wake/resume
issues after standby.
Highlights:
- Unattended listener mode now routes local file access, workspace edits, and approved
test/build commands through the supervisor instead of giving the runner direct local
authority. - Added an outbound broker-send guard that blocks obvious secrets and sensitive local
data before they leave the machine. - Fixed standby recovery so a new active HOST message correctly wakes the session instead
of surfacing a stale “Both agents have signaled STANDBY” pause. - Fixed stale queued standby artifacts that could cause old replies or prior refusals to
reappear on later turns. - Tightened unattended runner permission templates so broker replies and local actions
stay supervisor-mediated. - Expanded regression coverage for policy enforcement, outbound secret blocking, standby
wake behavior, and multi-turn unattended listener sessions.
Compatibility notes:
- Web access behavior is unchanged in this release: when enabled by the listener owner,
web access remains runner-managed. - Existing startup UX and listener policy choices remain authoritative.
