Project Decisions

These decisions close the open items from AGENTS.md § 11 for the current build.

Charging method: manual deposits first, with USDT/manual references stored in deposits.tx_ref.
Backend and database: Node.js, Express, MySQL/MariaDB.
Frontend: static HTML/CSS/JavaScript served from public/ by Express.
Currency: USD-denominated decimal balances with four fractional digits.
Markup: global default from DEFAULT_MARKUP_PERCENT, stored per synced service as markup_percent, with admin override for sell_price or service activation.
Provider API: Perfect Panel-compatible API through PROVIDER_API_URL and PROVIDER_API_KEY. Real provider credentials must be configured in environment variables before production.
Languages: Arabic UI/messages for the current frontend; API internals and code comments stay English.

Partial order handling:

partial orders are recorded with remains, start_count, and provider_charge.
Automatic refunds are intentionally disabled for partial until the provider's exact partial/refund semantics are confirmed.
