Surface auto recharge as a callout in the balance card

[mrmps]

Auto recharge was a one-line row inside Billing details — technically present, practically invisible. Mobbin survey of pay-as-you-go billing pages shows the established pattern is a callout inside the balance card, not a settings row: OpenAI Platform ("Auto recharge is off — …your API requests will stop working. [Enable auto recharge]"), WRITER, Perplexity, fal — and Exa does the same.

Now, directly under the available balance:

• Off: ⟳ Auto recharge is off — When your balance runs out, new requests stop. Enable auto recharge to top up automatically. with a primary Enable auto recharge button that opens the settings dialog with the switch pre-enabled.
• On: ⟳ Auto recharge is on — Adds $10.00 when your balance falls below $2.00 · $0.00 of $50.00 used this month with Edit.
• Failed charge: destructive-tinted border, "update your payment method; retries pause for an hour" with Update payment method + Edit.
• Non-owners see the state without buttons; the strip only renders when pay-as-you-go is configured.

Uses the existing Nucleo icon set (new Refresh alias). Verified SSR on the dev server in off and on-with-cap states; 864 tests pass, typecheck green.

📝 Walkthrough

Walkthrough

The billing page moves auto-recharge status, controls, and failure messaging into a pay-as-you-go panel. The enable action opens the editor with auto recharge enabled. The icon exports a Refresh alias, and the billing-page test checks the updated enable label.

Changes

Billing auto-recharge

Layer / File(s)	Summary
Auto-recharge panel and editor flow src/components/ui/icons.tsx, src/features/billing/credits.tsx, tests/payment-method.test.ts	The billing page adds a pay-as-you-go panel with auto-recharge status, amount, threshold, monthly cap usage, and failure details. It moves the related controls and payment-method setup into the panel. The enable action opens the editor with auto recharge enabled. The test expects “Enable auto recharge” when no payment method is on file.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 28db8

Accounts without a monthly maximum cannot see their monthly usage in the new panel. This is a bounded display issue that can be fixed before merge or accepted for follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 28db8

The new control uses the existing billing editor and owner-restricted save path. No introduced authorization bypass was found, but the underlying authentication controls and some concurrent-edit behavior were not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The mutation takes settings values rather than a caller-supplied account ID and binds the update to the account ID returned by ownerBillingContext. The demonstrated write scope is the authenticated owner's active account.

Trust Boundaries and Controls

• observed — The new enable button reaches the same save handler as the edit controls. Server-side validation and ownerBillingContext remain between client-controlled settings and the database write; the underlying authentication and same-origin implementations were not independently inspected.

Resilience and Maintainability Implications

• observed — A failed save reports an error and permits retry; the database update is a single statement. Protection against stale concurrent owner edits is not demonstrated, but that limitation is in the pre-existing save path.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Show monthly usage when the monthly maximum is blank.

When autoRecharge.capCents is 0, this condition hides autoRecharge.monthUsedCents. An account without a monthly maximum therefore cannot see its monthly usage in the new panel. Show the amount used for every enabled account. Show “of {cap}” only when a cap exists.
