Overview
A lightweight market-data tool. Version one deliberately leaves out infrastructure like Redis and WebSockets: the goal was a small, correct, shippable product, with the option to add a real-time layer later if usage justified it.
Decisions
- No Redis or WebSockets in v1. Polling and in-process caching were enough for the first version, and the omission kept deployment to a single process.
