# Facilities and Resources

Ryan James York · https://ryanjamesyork.com/facilities

> The computing, data, provenance and laboratory resources the programme runs on, in the form of a facilities statement.

Stated at the level of a facilities statement; specific identifiers, locations and commercial terms are available to funders and partners under agreement.

## Computing

Modelling, training and Monte-Carlo evaluation run on rented GPU instances of the 24 GB class in a secured United States region, with persistent volumes, and on a local CUDA workstation. Toolchains are pinned by version and every run records its configuration and output digests. No result depends on hardware that cannot be rented again.

## Data infrastructure

Source and pointers are held in version control with a content-addressed binary store, synced by an idempotent, resumable process under an append-only doctrine; a single commit identifier reproduces the corpus. Off-site copies go to immutable, object-locked storage with a daily, weekly and monthly retention ladder and periodic read-back verification. Secrets and deploy keys are held per repository and never committed.

## Provenance and verification tooling

An append-only, hash-chained, Ed25519-signed artifact ledger with four checks per entry; an instrument journal that signs each measurement at acquisition with per-instrument sequence numbers; a release gate that runs determinism, reproducibility, cross-model agreement, journal validity, optimisation-gain and probe-sanity checks before any result is admitted ([Finding 2026.4](https://ryanjamesyork.com/findings/2026/4)); and a claim-status discipline carried in every artifact's metadata. The verifier is a separate implementation from the writer.

## Laboratory access

The programme is self-funded and holds access to dry-laboratory analysis capacity and, through academic characterisation partners on a fee-for-service basis, to wet-laboratory space and characterisation instruments: Raman spectroscopy at several excitation wavelengths, atomic-force microscopy, and focused-ion-beam sectioning. Materials and measurement are bought rather than built: commercial CVD graphene wafers and films, pre-patterned field-effect test chips, a probe station, and a glovebox, with day-rate instrument time for Raman and AFM. The programme owns the method (the pipeline, the harness, the ledger) rather than the instruments.

## Personnel

The author leads the programme and the platform. A small team of part-time researchers covers dry-laboratory analysis and, at the measured phase, acquisition at partner instruments, with a fractional metrology and quality consultant engaged for the blind-repeatability and verification legs. The team expands with funding.

## Research environment

The work is carried out by SSX360 Corp., a Delaware corporation based in Honolulu, Hawaiʻi, whose provenance and audit tooling is the programme's infrastructure and whose open protocol, [Matrix Scroll](https://ryanjamesyork.com/software), is released under Apache-2.0. The company's positioning as an independent audit layer, one that never holds the keys of the systems it verifies, is the institutional form of the programme's independence rule ([§2.5](https://ryanjamesyork.com/2#s5)).
