Yellow private channels

Run SPECTER-backed channel discovery and management with Yellow endpoints

Create flow

1. Call POST /api/v1/yellow/channel/create with recipient, token, amount.
2. Receive generated stealth address and announcement data.
3. Backend publishes announcement with channel metadata to registry.

Discover flow

1. Recipient calls POST /api/v1/yellow/channel/discover with keys.
2. API scans registry and returns discovered channels.

Practical caveats

• Fund and close endpoints return placeholder tx hashes in current backend behavior.
• Final settlement is dependent on external Yellow infra and not fully executed by this backend.
