A live, working single-page paper-trading demo: it simulates a virtual USDG portfolio traded across three markets on "Robinhood Chain," with fills clearly labelled as simulated (no swap is signed or broadcast).

- Problem
- A live, working single-page paper-trading demo: it simulates a virtual USDG portfolio traded across three markets on "Robinhood Chain," with fills clearly labelled as simulated (no swap is signed or broadcast).
- Jev’s role
- TypeSafe Jev selects buy, sell, or hold for all three markets in one request, then sizes each trade with a Score across five levels that sets position size (0.5-5% of gross portfolio value).
- Architecture
- 3Route finds prices/routes on-chain → Jev decision (buy/sell/hold + sizing Score) per market → simulated fill applied to a virtual portfolio.
- Why it matters
- Pairs Jev's decision output directly with a routing protocol (3Route) rather than a coding agent or classifier pipeline — the trade-execution boundary (dry-run only, explicitly labelled) is kept separate from the decision boundary.
Code boundary
Jev answers the bounded questions described above. Thresholds, retries, side effects, and anything that must be reproducible stay in the surrounding application code. The research record does not capture this project’s exact question set or threshold values; read the linked source before copying the architecture.

Limitations
- A located repository or demonstration does not establish production reliability or independent validation.
Reusable pattern and related records
- Decision sidecar PlausibleA typed judgment service sits beside ordinary code; code owns effects and safety boundaries.
- Agent Model Router Authored HypothesisA drop-in router that selects model, reasoning effort, and fallback policy per step.
- Jev exposes constrained decision primitives for Boolean probability, choice distributions, and ordered scores. DemonstratedThe public API documentation defines `noul`, `choice`, and `score` response shapes.
- Decision quorum PlausibleMultiple typed judgments are aggregated through voting or confidence-aware stopping.
