First public open-source release of Cairn.

Cairn is a general-purpose problem-solving engine built around explicit state-space search. It was first validated on autonomous penetration testing and CTF-style tasks, but the underlying architecture is designed for broader goal-directed problem solving.

Highlights

• Explicit fact-intent graph for modeling progress through an unknown state space
• Blackboard-based coordination model with shared, objective state
• Three-task execution loop: Bootstrap, Reason, and Explore
• Docker-based dispatcher with per-project worker containers
• Interactive server UI for inspecting projects, facts, intents, and hints

Included in this release

• Initial public release of the Cairn server and dispatcher
• Default prompts and worker execution flow
• Current project protocol and documentation
• Public README, demo media, and setup instructions

Notes

• This is the initial OSS release of Cairn and the project is still evolving quickly
• Interfaces, prompts, and runtime behavior may change across early versions
• Cairn can support penetration testing, security assessment, and vulnerability research, but should only be used in explicitly authorized environments
