Key Features Implemented:

Predictive Velocity Engine (
VelocityEngine
):
Implemented a scientific "Harvest Maturity" algorithm that calculates Growing Degree Days (GDD) and correlates them with satellite-derived heat units.
The engine predicts the 0-100% readiness index and estimated yield volume (KG) per farm, adjusting for soil health and moisture stress.
Autonomous Futures Trading (
ForwardContract
):
Created a high-fidelity market model for Forward Contracts and Price Hedging.
Dynamic Hedge Ratio: As a core L3 requirement, the system automatically adjusts the hedge ratio (the percentage of crop to lock in) based on "Weather Volatility" scores. High volatility triggers higher lock-ins to protect the farmer against potential crop failure.
Forward-Looking Traceability:
Enhanced the
SupplyBatch
model to include a predicted_quality_grade based on pre-harvest environmental flux, allowing buyers to bid on specific quality standards weeks before the harvest.
Yield Liquidity API:
Implemented endpoints at /api/v1/futures/liquidity to allow farmers to see their predicted yield and recommended hedge positions.
Added /contract/lock for executing autonomous and manual trades.
Autonomous Market Sync & Audit:
Created a daily Celery task (tasks.velocity_market_sync) that updates maturity indices across all farms and adjusts hedge logs.
Enhanced the
AuditLog
with an autonomous_decision_flag to track AI-driven bidding decisions for financial audits.
