What is live.
What is not.

EPSILON separates working behavior from future ambition. This page is the public contract for method, data, and limitations.

Operational

Evidence engine

Baseline + four atomic perturbations + one joint execution stress

Operational

Machine-evaluable metric, operator, threshold, and required scope

Operational

epsilon.evidence.v2 JSON with calculation and data fingerprints

Documented

Signals use information through the prior close; positions apply to the next return

Not connected

Research instrument only; no orders, brokerage, or custody

Evaluation access

Adjusted daily bars are queried server-side under the owner’s provider account and remain subject to provider terms.

Method / no hidden leap

A claim is paired with a metric, comparison operator, threshold, and perturbation scope before computation.

Historical strategies use only information available through the prior close. This prevents same-period look-ahead.

Four one-factor runs isolate sensitivity; one joint stress exposes execution interactions. Survival is evidence of local robustness, not proof.

The export includes configuration, exact outcomes, baseline ledger, provider provenance, limitations, and deterministic fingerprints.

Limitations / read before use

Not investment advice.Results are research outputs and do not recommend trades or predict future performance.
Historical universes are user-selected.EPSILON does not yet provide a point-in-time constituent database, so survivorship bias remains possible.
Adjusted bars simplify reality.Daily close-to-close simulation omits intraday liquidity, market impact, taxes, borrow constraints, and partial fills.
Public open corpus is pending.The bundled corpus manifest remains unapproved; it is not used by the production engine.
No account or storage layer.Claims and settings are processed to produce the response and are not stored by EPSILON.
