Highlights

Caretaker LLM Triage Orchestrator: Implemented the LLM triage orchestrator and container build configuration to support caretaker triage workflows.
Enhanced Workspace Trust & Sandbox Hardening: Aligned macOS permissive Seatbelt profiles with the deny-default model and enforced workspace trust and task isolation in the Agent-to-Agent (A2A) server to prevent remote code execution (RCE).
Core Robustness & API Protections: Mitigated infinite ReAct and prompt injection loops, and prevented 400 Bad Request errors by grouping cancelled tool responses and coalescing consecutive roles.
Robust Credentials & Fallbacks: Restored the GOOGLE_APPLICATION_CREDENTIALS environment variable fallback and sequentially verified cached credentials.
Evaluation Coverage Reporting: Added a new command to generate comprehensive eval coverage reports.
