+# FRE-4522 - Update spamshield.config.ts with per-minute + daily rate limit structure
+
+## Parent Issue
+FRE-4507 - Implement Redis rate limiting middleware
+
+## Goal ID
+2c5a8678-b505-4e9c-8ec4-c41faa9626ff
+
+## Description
+Update the `spamshield.config.ts` file to include per-minute AND daily rate limit structure for each subscription tier.
+
+### Current State
+The current `spamshield.config.ts` only has single value rate limits:
+```typescript
+export const spamRateLimits = {
+  BASIC: 100,
+  PLUS: 500,
+  PREMIUM: 2000,
+} as const;
+```
+
+### Required Changes
+Refactor `spamRateLimits` to include both per-minute and daily limits:
+
+```typescript
+export const spamRateLimits = {
+  BASIC: { perMinute: 100, perDay: 1000 },
+  PLUS: { perMinute: 500, perDay: 5000 },
+  PREMIUM: { perMinute: 2000, perDay: 20000 },
+} as const;
+```
+
+### Type Definition
+Add type definition for the rate limit structure:
+```typescript
+export interface TierRateLimits {
+  perMinute: number;
+  perDay: number;
+}
+
+export type SubscriptionTierRateLimits = Record<SubscriptionTier, TierRateLimits>;
+```
+
+## Acceptance Criteria
+- [ ] Update `spamRateLimits` to include `perMinute` and `perDay` properties
+- [ ] Add `TierRateLimits` interface definition
+- [ ] Update `SubscriptionTierRateLimits` type
+- [ ] Ensure type safety with `as const` assertion
+- [ ] All existing imports/exports continue to work
+
+## File to Modify
+`services/spamshield/src/config/spamshield.config.ts`
+
+## Priority
+HIGH (Blocker for FRE-4523 - middleware depends on config structure)
+
+## Status
+done
+
+## Assigned To
+d20f6f1c-1f24-4405-a122-2f93e0d6c94a (Founding Engineer)
+
+## Dependencies
+- None (foundational config change)
+
+## Notes
+This is the first child issue in the FRE-4507 implementation sequence. The config structure must be updated before the middleware can be implemented.
