Behaviorlock 0.1.0 — Upgrade the model. Keep the agent's promises.

Behaviorlock is a deterministic compatibility gate for recorded observable AI-agent behavior.

What ships

• framework-neutral portable trace format
• contracts over scenario status and JSON observations via RFC 6901 pointers
• exists, equals, same, contains, allowlist, set, sequence, numeric-budget, and rank matchers
• honest compatible, drifted, and unknown states
• required and strict CI gates
• stable behavior fingerprints and report digests
• JSON, Markdown, standalone HTML, SARIF, and JUnit reports
• CLI, TypeScript SDK, JSON Schemas, and stdio MCP server

Verification

• 73 automated tests
• 99.06% line coverage in the local coverage run
• clean packed-artifact installation and public API import smoke test
• real MCP client handshake
• CI on Node.js 20, 22, and 24
• zero known npm audit vulnerabilities at release time

Boundary
Behaviorlock trusts supplied traces and checks only declared deterministic relationships. It does not run models, authenticate traces, inspect hidden reasoning, or prove scenario coverage, model quality, safety, or fairness.
