Forkline is a replay-first tracing and diffing library for agentic AI workflows that lets you deterministically reproduce, fork, and compare agent runs to find exactly where behavior diverged.

A reusable workflow engine that executes workflows defined in JSON, with deterministic replay and an event log.

Spec‑first, replayable agent coordination engine with append‑only traces, determinism, and 2026‑ready engineering practices.

Benchmark for statistically valid AI scientist systems, using audit-closed protocols, transparency logs, and sequential inference to prevent false discoveries in autonomous research agents.
