OpenClaw Signals: Async Bus Refactor lands, Registry Boot Fixes, and Hardened Sanitizers

Core Implementation

Async Bus Communication Refactor (PR #330)

The async bus communication refactor in PR #330 moves key signaling paths off of D-Bus. This is a heavy lift that promises lower latency for job triggers but requires careful validation to avoid race conditions in high-concurrency environments.

Bug Fix

Agent Registry Boot Stability (Issue #1559)

Issue #1559 highlights a nasty race condition where the agent registry loses critical context during an unexpected init cycle. This patch stabilizes the boot sequence, which is essential for any builder relying on strict uptime SLAs.

Security

Path Sanitization Hardening (PR #328)

Merging the path sanitization logic (PR #328) tightens up container escapes via malicious mount overflows. If you are running openclaw in multi-tenant or error-prone environments, this is a mandatory upgrade to prevent directory traversal attacks.

Documentation

Systemd Integration Docs Patch (Issue #1560)

Update #1560 resolves inaccuracies in the systemd integration docs that were causing silent failures in autostart configurations. The clarity here removes a major headache for anyone automating deployment pipelines on Linux hosts.
