GDBS is one geometric substrate running 138 deterministic, citation-backed tools across legal, senior care, finance, pharma, RF, construction, compliance, and scientific computing. Each runs in your browser with nothing uploaded, and every result carries a trust verdict you can re-run and check.
Deterministic, citation-backed legal tools that run entirely in your browser: case-law search against the Supreme Court index and CourtListener (keyless, no AI), regulatory watch over the Federal Register, court-deadline and statute-of-limitations calculators, a drafting toolkit, litigation utilities, and evidence custody with SHA-256 chain-of-custody logging. Every result cites the rule it applied, and nothing is uploaded.
Built for elder-law attorneys, senior financial planners, and skilled-nursing and assisted-living administrators. Statutory math for Medicaid look-back penalties and spend-down, Medicare IRMAA surcharges and SNF benefit periods, PDPM per-diem rates, HPPD staffing compliance, HECM reverse-mortgage limits, and VA Aid and Attendance, each keyed to the CFR sections it uses. Everything runs client-side, so no protected health information leaves the browser.
PDPM SNF Per-Diem Rate CalculatorA deterministic, in-browser calculator for the Medicare Part A skilled-nursing per-diem under the Patient-Driven Payment Model (P…
Transparent, deterministic financial math with no black box and no hidden rounding: option pricing with full Greeks, bond duration and convexity, IRR and NPV with a solver trail, private-equity waterfalls exact to the penny, real-estate underwriting, and a full stack of tax, payroll, and HR-compliance calculators keyed to their IRC and CFR sections. Loan amortization carries a GeoNum precision audit that shows exactly where naive floating-point accumulation stops being trustworthy.
401(k) Vesting Schedule CalculatorExact 401(k) employer-match vesting math over the IRC 411(a)(2) statutory schedules - in your browser.
Loan Amortization with Precision AuditExact amortization math with a GeoNum drift audit that shows where naive f64 accumulation stops being trustworthy.
Reproducible, auditable computation for a regulated field: clinical-trial sample size and power, bioequivalence confidence intervals against the FDA window, whole-body PBPK pharmacokinetics, and drug patent and exclusivity timelines, alongside biomedical solvers for cardiac electrophysiology, oxygen transport, bioheat, and tumor growth. Every result is deterministic with a precision trail, which is what an electronic-records compliance context asks for.

A verifiable computational-chemistry pipeline with no learned models: molecule generation, deterministic chemical-validity checking, property-targeted graph sampling by explicit-energy detailed-balance MCMC, molecular embedding and distance, and active-learning ligand screening. A geometric, auditable alternative to stochastic generative approaches.

BIM and construction
5 tools
Building physics and coordination in the browser, each citing its governing standard: envelope energy and dynamic thermal characteristics (ISO 13786 and 6946), clash detection and quantity takeoff broad-phased on the GMDBS HVP address space, modal and seismic response (ASCE 7 equivalent lateral force), room acoustics, and structural-frame analysis with ASCE 7 load combinations.
Deterministic, CFR-cited controls: AML and BSA transaction-threshold monitoring, CMMC and NIST 800-171 SPRS scoring with the exact DoD weights, ACA affordability and COBRA timelines, OFAC SDN sanctions screening (local and keyless), and Benford-style anomaly flags. Auditable by construction.
AML Transaction Threshold MonitorBright-line BSA/FinCEN reporting rules applied by exact arithmetic, every flag cited to its CFR section.
The GeoNum Trust Index scores content integrity and produces embeddable, tamper-evident verification badges, so the integrity of a result or a document can be checked independently rather than taken on trust.

The most technically dramatic slice, and the credibility anchor for everything else: numerical relativity, general-relativistic magnetohydrodynamics, a gravitational-wave pipeline, all-electron Kohn-Sham DFT, molecular dynamics, plasma MHD, computational fluid dynamics on CPU and WebGPU, finite-element structures, and more, each checked against an analytic or published benchmark, in the browser as the stage before the cluster. The same geometric substrate that runs these also runs the legal, finance, and elder-care tools above: the substrate is the product, and the plugins prove it generalizes.

The platform layer
15 modules
The connective tissue that makes these tools deployable where auditability and client communication are requirements: case management with sealed-field encryption, a client portal with a hash-chained audit trail, a persistent workspace over the stateless engine, and the trust-verdict layer.
QuantumValidated in-browser computation for quantum.
Sandbox WorkspaceA persistent workspace over the stateless engine - save, re-run, and share.
Theory LabValidated in-browser computation for theory lab.
