-## Terminology
-
-Audius runs on the **Open Audio Protocol**, which uses a single canonical node type: the **Open Audio Validator Node**. The earlier split between *Discovery Nodes* and *Content Nodes* is deprecated — both roles are now served by validator nodes. When writing docs, comments, commit messages, or user-facing strings, use "Open Audio Validator Node" (or just "validator node"). Do not introduce new references to "Discovery Node", "Content Node", "Creator Node", or "Discovery Provider". Directory names like `packages/discovery-provider` and `mediorum` are retained for compatibility but no longer reflect the architecture.

 ## Project Overview
 
 Audius is a decentralized, community-owned music-sharing protocol. This is a monorepo containing:
 
 - Web and desktop applications (React + Vite)
 - Mobile applications (React Native)
-- Backend services that together make up the Open Audio Validator Node software (indexer + media storage; see `packages/discovery-provider` and `mediorum` directories — names retained from earlier architecture)
+- Backend services (Discovery Provider, Content Node)
 - Blockchain smart contracts (Ethereum and Solana)
 - SDK and common libraries

+### Branching Rules
+
+- Always branch off main: `git fetch origin && git checkout -b your-branch origin/main`
+- Never branch off another feature branch
+- If a branch isn't based on main, rebase it: `git rebase origin/main`
+- Always work in the main repository worktree — never in Claude's auto-created worktrees under `.claude/worktrees/`
+
+### Environments
+
+- There is NO staging environment — only development and production
+- `npm run web:prod` is the correct command to run locally against prod
+- `npm run web:dev` runs against local protocol
+- The environment type is either `'development'` or `'production'` — never `'staging'`
+- Never add staging support or reference `staging.audius.co`
