Especially the ability to switch an ongoing conversation from Claude Code to Codex or Gemini (if you run out of tokens).
We’ve been working on security for multi-turn agent loops and noticed most detection approaches operate on isolated prompts. This paper introduces a framework for modeling intent trajectories across sequences in real time (<20ms), enabling enforcement before harmful actions occur.
Happy to answer technical questions or discuss assumptions in the paper.
Highflame’s new tool Palisade brings a zero-trust approach to the AI model supply chain. It validates format and structural integrity, detects hidden malicious patterns, verifies provenance via Sigstore/SLSA, and can even trigger behavioral checks to surface backdoors that only activate under certain inputs. Built in Rust for speed and scalability, Palisade makes it feasible to gate models before they hit inference servers or CI/CD pipelines, turning “download and hope” into a verifiable trust boundary.
Author here — happy to answer questions about threat models, performance tradeoffs, or how this fits into CI/CD.
Its free, extensible with yara support and can be adapted to the needs of an enterprise.
