tradingview/scanner-check — reverse-engineered prompt

Build me a simple data repository for checking what symbols should show up in a TradingView style market scanner.

I want separate JSON files for each market or asset group, like America, Canada, India, forex, crypto, bonds, futures, and so on. Each market should be able to have a blacklist for symbols that should not appear, a manual blacklist for things we explicitly hide, a manual whitelist for things we explicitly allow, and a validator whitelist where needed.

Keep it lightweight and easy for another service to read. No fancy app or UI is needed. The main goal is clean, consistent JSON files with predictable names so a scanner checker can load the right file for a country or asset type and know what to include or exclude.

Please set up the repository structure, add the market files, keep the naming consistent, and make sure the JSON is valid everywhere.
