## What it does / 核心功能

- Precious-metals vault / 贵金属账本（金库）: record jewelry, bars, and coins by category, metal, weight (g / oz / tael), purity (e.g. 9999, 999, 916/22K, 750/18K), and purchase cost. Material value = weight × purity factor × live market reference price.
- Buyback reference / 回收参考: material value × an adjustable discount. This is a personal estimate, not a dealer payout.
- Quotes / 行情: international spot, China market, and jewelry-store listing quotes side by side, each labeled with market, currency, and update time. Historical K-line and a weight ⇄ amount converter sit on the Quotes tab.
- Life ledger / 生活账本（记账）: income and spending converted into grams of gold at the current gold price (`grams = cash amount ÷ live gold price per gram`). Original cash amounts stay on the entry.
- Local-first / 本地优先: core ledgers stay in the device sandbox. No account is required. Optional Google / Apple sign-in is only for identity and alerts. Export `bullion-note-backup.json` via the system share sheet.

## Positioning / 口径

- Material value is not a jewelry-store retail price and not a guaranteed recycler payout.
- All quotes are reference figures with source and timestamp. Actual purchase, sale, or recovery amounts follow the dealer, exchange, or store.
- Bullion Note does not trade, hold funds, or give investment, tax, or legal advice.
