+
+## Task Completion Requirements
+
+- All of `bun fmt`, `bun lint`, and `bun typecheck` must pass before considering tasks completed.
+- NEVER run `bun test`. Always use `bun run test` (runs Vitest).
+
+## Project Snapshot
+
+Neon Code is a comprehensive portoflio management and equity research platform. It helps analysts manage their portfolio, organize research and view individual stocks. 
+
+This repository is a VERY EARLY WIP. Proposing sweeping changes that improve long-term maintainability is encouraged.
+
+## Core Priorities
+
+1. Performance first.
+2. Reliability first.
+3. Keep behavior predictable under load and during failures (session restarts, reconnects, partial streams).
+
+If a tradeoff is required, choose correctness and robustness over short-term convenience.
+
+## Maintainability
+
+Long term maintainability is a core priority. If you add new functionality, first check if there are shared logic that can be extracted to a separate module. Duplicate logic across mulitple files is a code smell and should be avoided. Don't be afraid to change existing code. Don't take shortcuts by just adding local logic to solve a problem.
