Seven-Layer Physics Materials Workbench

Materials Workbench is a CPU-side bench for in-silico battery and thermoelectric research.
Candidate chains arrive with schemas, validators, recompute checks, and dispatch wired together, so weak chemistries are rejected at the desk before they consume cluster hours. 3,547 strict-full tests pass and 588 Runpod-sim parity tests hold; the H100 campaign is the next wave, not the current result. Real GPU evidence is not claimed yet.

“Most candidate chemistries reach the cluster. vetting comes too late.”
Reject weak materials chains before any GPU runs them.
Today's stack threads DFT, phonons, MLIP, CALPHAD, phase-field, provenance, and lab automation through separate specialised tools. The gap is not a missing solver. It is a shared candidate record that lives before H100 spend.
Materials Workbench at Zer0pa/Materials-Workbench is an installable alpha that holds schemas, validators, seven recompute checks, packet records, Runpod dispatch, and an H100 cutover path in one CPU-side bench. Battery and thermoelectric candidates run the same pre-screen on a laptop today that they will run against real GPU artifacts in the H100 wave.
7 recompute checks, 16 stress cases, hash history over every chain.
Every chain replays on CPU before any GPU touches it.
The seven recompute checks take a candidate chain's outputs and re-derive every layer's hash from inputs. Any divergence rejects the chain; only chains that survive the recompute move forward.
The discipline runs today on CPU and on the Runpod-sim parity surface (3,547 strict-full + 588 parity). The H100 wave will run the same checks against real GPU artifacts. The unit of bit-exactness is per-chain, per-layer-hash.
No real GPU-backed runpod_rest artifact has been produced. Discovery of any material is not claimed. Public PyPI v0.1.0 is live but stale pending v0.1.1. License is SAL-7.1 / GitHub NOASSERTION; UMA/HF org, Materials Project credential, real endpoints, and EMMO cleanup remain open.
FIVE PATHS FROM ONE pre-GPU bench.
The hinge is not one chemistry result. It is a bench where candidate generation, validators, constraints, and run history travel together from a researcher's laptop to a GPU cluster. If that path survives H100 completion, materials exploration becomes something other teams can repeat, compare, and contest.
