# Tetracta — Quantitative Research Engine (methodology card)

> A capability and methodology overview of our production quantitative pipeline. **By policy this
> card contains no performance figures** — no Sharpe, no returns, no information-coefficient values,
> no signal internals. It describes *how* we build, evaluate, and harden, not *what the numbers are*
> or *what the alpha is.* Performance and signals are shared only with **licensed institutions**
> under contract, with appropriate disclaimers — never as retail investment advice.

## What it is
A production-grade, walk-forward, **multi-horizon cross-sectional** research pipeline:
**data → signal → model → decision**. It runs today and produces models on a live universe of
large-cap equities.

## Engineering discipline (the part that travels)

| Principle | What we do |
|---|---|
| **Leak-hardening** | Strict point-in-time discipline; no look-ahead in features, labels, or splits. |
| **Walk-forward** | Out-of-sample evaluation rolls forward in time; no in-sample cherry-picking. |
| **Placebo / null testing** | Every claimed effect is checked against a shuffled / null control to rule out artifacts. |
| **Statistical significance** | Effects reported with autocorrelation-robust significance, not raw point estimates. |
| **Multiple horizons** | Cross-sectional ranking is evaluated across several forecast horizons, intraday to multi-week. |
| **Honesty card** | Each result ships with a fixed disclosure of its assumptions, regime, and known confounds. |
| **In-production SPC** | The same gradient-norm / process-control gates that watch our LLM training also watch model health here. |
| **Deterministic** | Pipelines are reproducible end-to-end; results regenerate from sealed inputs. |

## Why it matters
This is rare bench strength: ~20 years of multi-sector industrial and analytical-engineering
experience (signal processing / FFT, predictive maintenance, optimization, numerical methods,
economics) applied to turning raw data into **decisions you can audit**. The methodology — not any
particular number — is the asset.

## How we engage (B2B only)
- **Technology / infrastructure licence** — license the pipeline to a licensed institution.
- **Research-as-input** — signals as a research input to a licensed institution, with disclaimers.
- **Build-out consulting** — stand up a model / backtest infrastructure with your team.
