Welcome to the Hydra One computational reproducibility and review packet. This repository serves as a bounded, advisory-only computational lane for green-hydrogen catalyst discovery. It contains a rigorously reviewed set of four top catalyst candidates, surrogate structure artifacts, and verifiable proof of existence (Prior Art) anchored on the blockchain.

The objective of this project is to screen bounded alkaline/AEM-adjacent oxygen-evolution catalyst candidates for green hydrogen production. Candidates were ranked based on a multi-factor score including activity, durability, cost efficiency, corrosion resistance, and manufacturability.

Target Parameters:

• Electrolyzer family: AEM
• Catalyst focus: Anode oxygen evolution
• Electrolyte environment: Alkaline
• Current density target: 0.88 A/cm²
• Maximum overpotential: 395 mV
• Durability target: 1850 h
• Max. critical mineral intensity: 0.30

After screening 24 initial candidates down to 13 review-grade candidates, the following four emerged as the strongest computational candidates. Below are their specific target parameters and surrogate formulas based on our multi-factor scoring:

Note: This packet represents a strong computational basis for follow-on scientific discussion. It does not yet claim physical synthesis readiness or experimentally confirmed crystal truth.

This packet is designed as a computational discovery accelerator and peer-review mechanism. Researchers and reviewers can leverage this repository in five distinct ways:

• 1. Crystallographic Analysis (3D Visualization): The .cif files inside the evidence_bundle contain the exact atomic 3D structures and lattices. These can be opened directly in visualization software (e.g., VESTA, Avogadro, or PyMOL) for visual inspection.
• 2. Advanced Simulation & DFT Routing: Researchers can bypass early trial-and-error by feeding these .cif structures into high-fidelity physical simulators (e.g., VASP, Quantum ESPRESSO). This allows independent teams to conduct their own deep Density Functional Theory (DFT) analyses on the Gibbs Free Energy profiles of the oxygen evolution reaction (OER).
• 3. Wet-Lab Synthesis Guidance: If theoretical experts validate these calculations, the specific stoichiometries, binder fractions, and support combinations provide explicit starting points for a chemist to synthesize the materials in a real wet-lab (e.g., via co-precipitation) for physical AEM testing.
• 4. AI Decision Logic Auditing: Reviewers can inspect the JSON files (such as hydra-one-campaign.json) to audit why the Hydra One system selected these top 4 candidates out of the initial 24, examining the algorithmic trade-offs made between durability, cost, and efficiency. The entire pipeline can be cryptographically reproduced using scripts/reproduce_bundle_outputs.mjs.
• 5. Intellectual Property & Prior Art: The Base L2 blockchain anchor serves as an immutable mathematical timestamp (Proof of Existence). This protects the public domain by acting as verifiable open Prior Art, preventing external entities from inappropriately patenting these specific simulated architectural designs.

• briefing/: Human-readable executive summaries, candidate details, and review guidelines.
• evidence_bundle/computational_repro_bundle_2026-03-23/: Machine-readable evidence, surrogate relaxations, and final CIF files for the top candidates.
• attachments/: Ready-to-send ZIP archives (if applicable).
