Highlights

This release adds Pi as a supported dispatcher worker backend.

Cairn can now run with Claude Code, Codex, or Pi workers, enabling more flexible agent orchestration for autonomous security exploration workflows.

What's New

• Added Pi worker support in the dispatcher
• Added Pi session recovery and JSONL output parsing
• Added conclude-phase compatibility for Pi execution flows
• Added Pi worker configuration example to dispatch.yaml

Notes

• Pi support has been validated across bootstrap, reason, explore, and conclude flows
• Existing Claude Code and Codex worker behavior remains unchanged
