- Database queries are in repositories only — no raw Drift queries in providers or widgets
- After any changes to Drift tables or DAOs, run `dart run build_runner build --delete-conflicting-outputs`
### Feature Gating Rules
- Never check `user.isVip` or `plan == UserPlan.vip` directly in widgets or screens
- All access control goes through `featureFlagsProvider` — read the relevant flag, wrap with `PaywallGuard`
- Quantity limits (e.g. max accounts) are enforced inside repositories, not in widgets — throw `FeatureLimitException` on violation
- Routes that are entirely VIP-only use GoRouter `redirect` reading `featureFlagsProvider`
- Adding a new gated feature means: add a getter to `FeatureFlags`, implement in `FreeFeatureFlags` and `VipFeatureFlags`, then use in UI/repo
## Code Style
**No comments anywhere in the codebase.** No `//`, no `/* */`, no `///` doc comments. Code must be self-explanatory through naming.

final flags = ref.watch(featureFlagsProvider);
return PaywallGuard(
canAccess: flags.canExportCsv,

**Quantity limits in repositories**:

final flags = ref.read(featureFlagsProvider);
final count = await _db.countAccounts();
if (flags.maxAccounts != -1 && count >= flags.maxAccounts) {
return Result.failure(FeatureLimitException());
}
return Result.success(await _db.insertAccount(account));

**VIP-only routes** — use GoRouter redirect, never guard inside the screen itself:
```dart
GoRoute(
path: '/analytics',
redirect: (context, state) {
final flags = ref.read(featureFlagsProvider);
return flags.canSeeAnalytics ? null : '/paywall';
},
