This system judges code and returns a verdict:\n\u003e **VERIFIED**, or a concrete **counterexample**.*\n\n**Forseti puts a formal verifier inside the agent's coding loop.** As coding agents write\nfaster than anyone can review, trust has to move from *\"a human looked at it\"* (LGTM) to\n*\"the code carries a proof\"* (Q.E.D.). Forseti closes that loop:\n\n```\nwrite  →  verify (ESBMC)  →  counterexample  →  fix  →  ↺\n```\n\nThe agent never hands you the broken draft — you see the version that already passed.\n\n## The bar (Jan 2027)\n\nA **demoable** ESBMC-in-the-loop system that self-corrects on a **non-toy** example,\nplus a public writeup. Engine fixes and a Lean backend are *supporting*, not the metric.\n\n## Status\n\nH2 2026 Igalia investment (Jul 2026 → Jan 2027).
