Summary

• Credit purchase descriptions showed a malformed amount, e.g. addition of 10 credits for Tokens at %!d(float64=1000)[usd].
• Checkout metadata is stored as JSON, so the synced Stripe amount_total reads back as a float64, and formatting it with %d fails. It is now converted with cast.ToInt64, the same way the product quantity is read.
• Stripe reports the amount in the currency's minor unit, so the description now shows it in the major unit with the ISO code, using golang.org/x/text/currency for the number of decimals: at 10.00 USD instead of at 1000[usd], and 1000 JPY for a zero-decimal currency. An unknown currency code keeps the old 1000[xyz] format.
• golang.org/x/text moves from an indirect to a direct dependency.
• Descriptions of credits that were already added are not changed.

📝 Summary

Summary by CodeRabbit

• Improvements
  • Credit descriptions now display Stripe totals in major currency units with the ISO currency code and standard decimal precision. When a currency code cannot be parsed, the amount is shown in minor units with the original code.

Walkthrough

Checkout credit descriptions now use formatted amounts with parsed ISO currency codes and currency-specific decimal scales. Invalid currency codes retain the minor-unit amount and original code in brackets.

Changes

Checkout credit descriptions

Layer / File(s)	Summary
Format checkout credit amounts billing/checkout/service.go, go.mod	When the total and currency are present, the checkout uses formatAmount in the credit description. The helper formats valid ISO currency codes as scaled amounts followed by the parsed code. Invalid codes use the minor-unit amount and original code in brackets. golang.org/x/text is declared as a direct dependency.

• observed — billing (service) was modified; 1 changed file maps to changed impact.
• observed — go.mod (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in billing/checkout/service.go: Added math and the currency, language, and message imports required for currency-aware amount formatting.
• observed — Modified behavior in billing/checkout/service.go: When both the total amount and a string currency are present, the credit description now uses formatAmount instead of displaying the raw amount followed by the currency code.
• observed — Modified behavior in billing/checkout/service.go: Added formatAmount, which parses the uppercased ISO currency code and returns the raw minor-unit amount with the original code in brackets if parsing fails. Otherwise, it uses the currency’s standard rounding scale to convert minor units, renders the amount with an English-locale narrow currency symbol, and removes the first space.
• observed — Modified behavior in go.mod: golang.org/x/text remains at v0.40.0 but is no longer marked as indirect.
