Overview

FYOS Methodology

FYOS uses a clean-core v2 methodology — a conservative, trust-aware framework for evaluating crypto yield opportunities.

This section explains how FYOS works and how to interpret its outputs correctly.

Core Principles

1. Score Is Not Deployability

edge_value_score_v2 measures opportunity attractiveness.

edge_capacity_24h determines deployability.

A high-scoring opportunity can still be undeployable if structural capacity is missing.

2. Gross Is Not Realistic

Raw funding APR or gross basis spread overstates realistic returns.

FYOS applies reality adjustments (fees, slippage, decay, trust haircuts) before presenting actionable metrics.

3. Persistence Uses Deterministic Decay

Current persistence handling comes from deterministic decay, not from deprecated survivability-led math.

4. Observed Risk Is Part Of The Core

Downside interpretation uses observed risk evidence — historical data about actual outcomes.

5. Prescriptive Outputs Are Bounded

  • Planner output is a bounded recommendation, not execution instruction
  • Simulator output is scenario analysis, not forecast truth
  • Reality output is an evidence surface, not a promise surface

Strategy Families

Historical / Deprecated

Two Strategy Families

FYOS supports two complementary strategy families:

Funding Arbitrage

Captures funding rate payments on perpetual futures.

  • Variable, ongoing returns
  • Open-ended duration
  • Primary metric: decay_adjusted_return

Basis / Cash & Carry

Captures the spot-futures spread on delivery contracts.

  • Fixed returns at entry (for hold-to-expiry)
  • Expiry-linked duration
  • Primary metric: model_adjusted_basis_apr

Both families share the same trust-aware, reality-adjusted framework.

What Is Deprecated

The following are not part of current primary methodology:

  • Survivability as primary score input
  • soft_capacity_usd as primary deployability truth
  • Old edge_value_score as canonical ranker
  • Survivability-weighted economics

These may appear in archives, diagnostics, or compatibility paths but are not certified for primary product use.

Interpretation Cheat Sheet

SignalMeaning
High edge_value_score_v2 + missing edge_capacity_24hAttractive, not deployable
bounded-grade coverageUsable, but reduced authority
Planner outputBounded recommendation
Simulator outputScenario result, not prediction
gross_basis_aprRaw view, not realistic
model_adjusted_basis_aprExecution-aware basis view

Philosophy

FYOS is designed as a pessimistic, trust-aware decision system.

The core belief:

Gross crypto yield is not the same as realistic deployable yield.

Therefore FYOS:

  • Is conservative by default
  • Avoids optimistic rescue logic
  • Separates signal from deployability
  • Exposes limitations explicitly
  • Uses scenario tools as scenario tools, not as guarantees

This methodology creates a system you can reason about honestly.
