better-data: Hydration and coercion

For library maintainers fixing or extending how stored / incoming values become typed property values on a DataObject. The coercion layer sits between the source's raw fetch and the constructor's typed parameters; modifying it touches every DTO that goes through ::fromArray.

Misconception this skill corrects

"I'll just settype($value, 'int') or (int) $value inside the hydrator — same effect."

Wrong. PHP's silent casts paper over invalid input — (int) 'abc' === 0, (int) '12foo' === 12, (bool) 'false' === true. better-data's coercion is intentionally strict: surprising input becomes TypeCoercionException with the field name, expected type, and offending value. Verified at src/Internal/TypeCoercer.php:46-58 and the per-helper throws (toString:197, toInt:218, toFloat:235, toBool:254).

The discipline is:

// WRONG inside coercion code
$intValue = (int) $value;

// RIGHT
$intValue = TypeCoercer::toInt($dtoClass, $fieldName, $value);
// throws TypeCoercionException if $value isn't a coercible int — caller gets the field
// name and value in the message instead of silently storing 0.

Other AI-prone misconceptions:

"I'll add a WP function call inside TypeCoercer — it makes the code shorter." Wrong — TypeCoercer is the one engine that MUST stay WP-free so its tests can run without a WP runtime. WP-aware logic goes in DataObject::coerceParameter or in the source.
"I'll add the Encrypted decryption to TypeCoercer." Wrong layer — attribute-aware coercion lives ABOVE TypeCoercer in DataObject::coerceParameter (src/DataObject.php:168). The pattern is: handle the attribute (decrypt, walk the list), then call TypeCoercer::coerce with the simpler value.

When to use this skill

Trigger when ANY of the following is true:

A bug report says "fromArray hydrates with the wrong type" or "casting issue".
The diff modifies src/Internal/TypeCoercer.php or src/DataObject.php::coerceParameter.
Adding support for a new primitive type or a new attribute that affects coercion.
Reviewing a PR that calls settype(), intval(), (int), or (string) inside coercion code.
Hitting TypeCoercionException at runtime and triaging.

Workflow

1. Choose the layer

Change type	Layer
New primitive (decimal type, IPv4 stored as string <-> int)	`TypeCoercer` (pure)
New WP-builtin handling (e.g. coerce `WP_Term` to a term ID)	`TypeCoercer` (still pure — `WP_Term` is just a class shape; check `instanceof` doesn't require WP runtime)
New attribute affects coercion (`#[Slug]` lowercase before string-coerce)	`DataObject::coerceParameter` (above TypeCoercer)
New attribute affects encryption / list coercion	`DataObject::coerceParameter`

The acid test: "Can my code run inside a unit test that does NOT bootstrap WordPress?" If yes, it can live in TypeCoercer. If no (calls wp_remote_get, reads $wpdb, looks up WP_User), it must live elsewhere.

2. Adding a primitive coercion

Inside TypeCoercer::coerce (src/Internal/TypeCoercer.php:83-88):

return match ($targetTypeName) {
    'string' => self::toString(...),
    'int'    => self::toInt(...),
    'float'  => self::toFloat(...),
    'bool'   => self::toBool(...),
    'array'  => self::toArray(...),
    // your new branch:
    'decimal' => self::toDecimal($dataObjectClass, $fieldName, $value),
    default  => throw TypeCoercionException::unsupportedType(...),
};

The helper:

private static function toDecimal(string $cls, string $field, mixed $value): Decimal
{
    if ($value instanceof Decimal) {
        return $value;
    }
    if (is_string($value) && \preg_match('/^-?\d+(\.\d+)?$/', $value)) {
        return new Decimal($value);
    }
    if (is_int($value) || is_float($value)) {
        return new Decimal((string) $value);
    }
    throw TypeCoercionException::for($cls, $field, 'decimal', $value);
}

Three rules:

Accept the type-as-input shortcut. $value instanceof Decimal returns it unchanged — caller passes back what they got.
Convert from common neighbors. Decimal accepts strings, ints, floats; rejects arrays, booleans, objects of other types.
Throw TypeCoercionException::for(...) with class + field + target + offending value when nothing matches.

3. Adding an attribute-aware coercion

Inside DataObject::coerceParameter (src/DataObject.php:168-220) BEFORE the TypeCoercer::coerce final delegation:

private static function coerceParameter(ReflectionParameter $parameter, mixed $value): mixed
{
    // Existing #[Encrypted] decryption (idempotent envelope check) — see lines 173-184.

    // Your new attribute-aware coercion — example: #[Slug] lowercases before string coerce.
    $slugAttr = $parameter->getAttributes(Slug::class)[0] ?? null;
    if ($slugAttr !== null && is_string($value)) {
        $value = \mb_strtolower($value);
        // Don't return here — let TypeCoercer handle the final string coercion below
        // so length / max-length attribute can also apply.
    }

    // Existing #[ListOf] handling (lines 185-208).

    // Final fallback to pure TypeCoercer.
    return TypeCoercer::coerce(
        static::class,
        $parameter->getName(),
        $parameter->getType(),
        $value,
    );
}

Pattern: read the attribute → mutate $value (or recurse, or replace) → fall through to TypeCoercer for the final type cast. Don't duplicate TypeCoercer's logic above it.

4. Idempotency for read-side transformations

#[Encrypted] is the canonical example of an idempotent transformation (DataObject.php:173-184):

if (is_string($value)
    && $value !== ''
    && EncryptionEngine::looksEncrypted($value)
    && $parameter->getAttributes(Encrypted::class) !== []
) {
    $value = EncryptionEngine::decrypt($value, $parameter->getName());
}

Three checks: is it a non-empty string, does it look like a bd:v1: envelope, does the property carry #[Encrypted]. If any check fails, the transformation no-ops — so a freshly-decrypted value passing through this path again doesn't double-decrypt. Apply the same idempotency principle to your transformation.

5. Tests

Each coercion path needs unit tests:

Primitive coercions → tests/Unit/TypeCoercionTest.php. Cover the type itself, neighbor types (int from numeric string, etc.), and rejection (array → int throws).
Attribute-aware coercions → their own file, e.g. tests/Unit/SlugAttributeTest.php, tests/Unit/ListOfTest.php, tests/Unit/EncryptedAttributeTest.php, tests/Unit/SecretTest.php.

Two specific shapes per coercion:

public function test_it_coerces_a_valid_input(): void
{
    $dto = MyDto::fromArray(['decimalField' => '1.50']);
    $this->assertInstanceOf(Decimal::class, $dto->decimalField);
    $this->assertSame('1.50', (string) $dto->decimalField);
}

public function test_it_throws_on_invalid_input(): void
{
    $this->expectException(TypeCoercionException::class);
    MyDto::fromArray(['decimalField' => 'abc']);
}

6. Run the full check

vendor/bin/phpunit
vendor/bin/phpstan analyse --memory-limit=1G
vendor/bin/php-cs-fixer fix
wp better-data stress  # if the change can affect WP-side hydration

Critical rules

TypeCoercer stays pure. No WP function calls, no $_* superglobals, no globals, no constants. Must be unit-testable without WP bootstrap.
Attribute-aware coercion lives in DataObject::coerceParameter. Read attribute → transform value → optionally fall through to TypeCoercer.
Use the explicit helpers (toString, toInt, toFloat, toBool, toArray). Never settype(), intval(), (int) cast on unchecked input — those silently turn invalid data into 0/false.
Throw TypeCoercionException on anything surprising. Caller gets class + field + expected type + offending value in the message.
Idempotency for read-side transformations. A value that's already been transformed (decrypted, lowercased, parsed) should pass through unchanged on the next call. Use a "looks like the post-transform shape?" check.
Accept the type-as-input shortcut. If a coercion target is Decimal, Decimal $value === $value short-circuits.
Single-attribute change goes in ONE PR with all relevant engines wired. A new attribute that affects coercion also affects RestSchemaBuilder, sink projection, etc. — don't ship partial.

Common mistakes

// WRONG — settype inside coercion
private static function toInt(string $cls, string $field, mixed $value): int
{
    \settype($value, 'integer');  // 'abc' silently becomes 0
    return $value;
}

// RIGHT — explicit checks + throw on bad input
private static function toInt(string $cls, string $field, mixed $value): int
{
    if (\is_int($value)) {
        return $value;
    }
    if (\is_string($value) && \preg_match('/^-?\d+$/', $value)) {
        return (int) $value;
    }
    if (\is_float($value) && \floor($value) === $value) {
        return (int) $value;
    }
    throw TypeCoercionException::for($cls, $field, 'int', $value);
}

// WRONG — WP function call in TypeCoercer
private static function toUserId(string $cls, string $field, mixed $value): int
{
    if (\is_string($value)) {
        return (int) \get_user_by('login', $value)?->ID;  // WRONG: not WP-free
    }
    return self::toInt($cls, $field, $value);
}

// RIGHT — keep WP-aware logic in src/Source/ where it belongs

// WRONG — duplicating TypeCoercer logic in coerceParameter
private static function coerceParameter(ReflectionParameter $parameter, mixed $value): mixed
{
    $type = $parameter->getType()->getName();
    if ($type === 'int') {
        return (int) $value;  // WRONG: reimplements toInt, loses the validation
    }
    // ...
}

// RIGHT — let TypeCoercer handle primitive types after attribute logic
return TypeCoercer::coerce(
    static::class,
    $parameter->getName(),
    $parameter->getType(),
    $value,
);

// WRONG — non-idempotent read-side transformation
if ($parameter->getAttributes(Encrypted::class) !== []) {
    $value = EncryptionEngine::decrypt($value, $parameter->getName());
}
// Crash on the second pass: trying to decrypt already-plaintext value.

if (\is_string($value)
    && $value !== ''
    && EncryptionEngine::looksEncrypted($value)
    && $parameter->getAttributes(Encrypted::class) !== []
) {
    $value = EncryptionEngine::decrypt($value, $parameter->getName());

# better-data: Hydration and coercion
