Invention you can check.
PIE is an evolutionary invention engine where physics is the only judge. It evolves engineering geometry from scratch — and it is architected so it cannot lie about the results. Every solver result on this site traces to a hashed artifact, and the manifest that proves it is published.
See the evidence What it can discover The run that failed honestlyCalculiX-certified declared envelope
An evolved AM payload bracket carries a declared 200 kg-payload rotorcraft load envelope where the conventional plate-and-gusset design fails torsion outright. Same solver, same material, same load cases. It is heavier than the conventional part — 1.165 kg vs 0.946 kg. We say that plainly, because the alternative is you finding out later.
The receipt on the right is not a mock-up. It is the certification record for that bracket — CalculiX static + eigenfrequency on a Gmsh mesh of 31,487 nodes / 126,665 tets. Full case study →

} Two hands, and a firewall between them.
Evolutionary search over CPPN networks, field-lattices, hybrid genomes. LLMs and surrogates may suggest and route. They are firewalled from ever judging fitness.
CalculiX FEA on Gmsh meshes, lattice-Boltzmann pore flow, validated in-house cores. Only real-solver results are claim-grade.
Preregistered claims, an append-only ground-truth ledger, and a compiler that machine-traces every published number to a hashed artifact.
The same engine and the same firewall run at every scale — crystal microstructures, architected lattices, printable components, water and power networks, coupled machines, dynamical systems. The full range, with each family's evidence tier →
How the architecture works
A combustion-chamber sector coupon, print-ready.
Built to a turbojet OEM's publicly documented envelope: CalculiX FEA
(axial E 136.72 GPa, first yield
165.01 MPa), converged pore-flow LBM, watertight
print files. Its report's 10 headline claims machine-compiled
ALL_TRACED.
Nine campaigns. The search got better each time.
validated_sidecar not a baseline beat
Across nine real-solver-certified campaigns on the same declared engine-support bracket contract, PIE's own best safety-passing design got 47.2% lighter campaign to campaign, and 56.3% lighter within a single 12-hour run — every point CalculiX/Gmsh certified. The declared naive baseline for this contract still fails outright (SF 0.748 against 1.5 required), so there is nothing passing to beat. This is the search improving against itself, stated as exactly that. Full case study →
The proxy promised twelve winners. The solver failed all twelve.
A 1,063-generation run, driven by a fast in-loop proxy, sent its twelve best candidates to CalculiX certification. Real torsion safety factors came back 0.97–1.28, all below the 1.5 bar. Nothing shipped.
Then the system turned on its own proxy:
- measured it 40.1% optimistic — 12 of 12 candidates over-promised
- found its reported accuracy understated ~81× against reality
- found its confidence band ~48σ too narrow
- filed all 12 failures in the failure museum as evidence for the next run
Most engineering-AI pipelines would have published the mirage. PIE's architecture exists so it can't.
The full story, with numbersHeld to its own rules.
Envelope, load cases, safety bar, baseline and the exact claim ceiling — frozen before iteration 1, so the claim cannot be adapted to the result.
Append-only, content-addressed record of every real-solver certification — passes and failures. Proxy results cannot enter by construction.
Every outbound number maps to a JSON path in a hashed artifact and is machine-checked: ALL_TRACED, or named failures. No manifest, no publication.
An independent verification lane re-runs the rulers itself rather than accepting reported numbers. No result grades itself.

Your load envelope, your boundary conditions. PIE evolves and solver-certifies candidates; you get print-ready geometry and the full evidence chain.
