# Elata Development Rules

## Project Context
This is an Elata app built on the Elata protocol with biometric SDK integration.

## Key References
- Protocol docs: https://docs.elata.bio/apps/what-are-elata-apps
- SDK docs: https://docs.elata.bio/sdk/overview

## SDK Packages
- `@elata-biosciences/rppg-web`: Camera-based rPPG (createRppgSession)
- `@elata-biosciences/eeg-web`: EEG processing (initEegWasm, band_powers)
- `@elata-biosciences/eeg-web-ble`: Web Bluetooth (BleTransport)

## Protocol Contracts
- AppFactory: deploys token stacks
- AppBondingCurve: constant-product price discovery
- FeeRouterV2: fee routing (80% contributors, 20% treasury)
- ContributorSplit: pull-based contributor payouts

## Standards
- TypeScript, React, Vite
- Use createRppgSession for rPPG (not raw processor)
- Use BleTransport.startStreaming() for BLE
- No em-dashes
