Vanna Federation

Flower ServerApp + ClientApp for five isolated FX desks.

Desks train an XGBoost model on private execution history. Only model updates leave the desk. The server aggregates with FedXgbBagging and exports one approved file: provider_evidence.json (fill, reject, slippage, latency per LP). Raw orders, client IDs, UTIs, and live intent are never shared.

This is one of two Flower App Bundles. Flower will not put an AgentApp in the same FAB as a ServerApp/ClientApp. The sister app is .

Simulation (local)

Expect 5 virtual SuperNodes. No Flower config edits required.

cd apps/federation
uv sync
uv run flwr run . --federation-config="num-supernodes=5" --stream

The ClientApp reads partition-id from context.node_config and generates deterministic synthetic desk data (or loads a saved partition if present).

SuperGrid (deployment)

Federation: @molyleela/Vanna. Needs 5 real SuperNodes online.

uv run flwr login supergrid
uv run flwr run . supergrid --federation @molyleela/Vanna --stream

Desk data stays on the SuperNode. Do not pass raw order files into the shared payload.

What this app does not do

Does not execute trades
Does not blacklist liquidity providers
Does not share client identities
