# Named buckets

Credits can be split into independent, named pools on the same entity — for example promotional and purchased credit that should never be spent against each other. On the facade, bucket() narrows the scope; buckets(\[...\]) sums several for reading:

```php
$promo = Credits::for($user)->bucket('promotional');   // an immutable scope — keep and reuse it
$promo->add(100, 'welcome promo');
$promo->balance();                                     // 100

Credits::for($user)->bucket('purchased')->add(50, 'top-up');

Credits::for($user)->buckets(['promotional', 'purchased'])->balance(); // 150 — summed, read-only
Credits::for($user)->total();                                          // every bucket
```

Every trait method accepts the same optional bucket argument:

```php
$user->modifyCredits(100, 'welcome promo', bucket: 'promotional');
$user->modifyCredits(50, 'top-up', bucket: 'purchased');

$user->creditsBalance(bucket: 'promotional'); // 100
$user->creditsBalance(bucket: 'purchased');   // 50
```

Balances are fully isolated per bucket, and the overdraft guard is enforced per bucket — a deduction against purchased cannot draw on promotional credit.

## The default bucket

When you omit the bucket, the configured default\_bucket ('default') is used for both reads and writes. A bucket-less balance query therefore returns the default bucket only — it does not sum across every bucket:

```php
$user->modifyCredits(25);                         // lands in the 'default' bucket
$user->creditsBalance();                          // 25  (the default bucket only)
$user->creditsBalance(bucket: 'promotional');     // 100
```

Single-pool usage needs no changes: every call without a bucket operates on one pool. setCreditsTo() and hasCredits() take the same bucket argument, and credits:modify has a --bucket= option.

## Totals across buckets

When you do want a combined figure, sum a chosen set of buckets or every bucket the entity owns:

```php
// Sum a chosen set of buckets (names are de-duplicated; an empty list returns 0).
$user->creditsBalanceForBuckets(['promotional', 'purchased']); // 150

// Sum every bucket on the entity.
$user->totalCreditsBalance(); // 175

// Both accept an optional point-in-time argument.
$user->totalCreditsBalance(now()->subWeek());
$user->creditsBalanceForBuckets(['promotional', 'purchased'], now()->subWeek());
```

Each bucket fits the signed 64-bit ledger, but several together may not: a total past int64 throws money’s AmountOverflow instead of returning a capped number.
