better-data: Adding a sink

For library maintainers integrating WRITE-side support for a new WordPress data store with better-data — comment meta, attachments, custom taxonomies, plugin-specific tables. The shape is set by PostSink and OptionSink; deviating breaks the HasWpSinks trait API and surprises consumers who've internalized the dual projection-vs-convenience model.

Misconception this skill corrects

"I'll write the values directly to update_post_meta — slashing is the caller's problem."

Wrong direction. WordPress's write pipeline calls wp_unslash() on inbound data on the way to the DB. If you pass a raw value through update_post_meta($id, $key, 'a"b') without slashing first, WP unslashes a string with no slashes and stores 'ab' (the " survives, but escaped/quoted values get mangled). Convenience methods (insert, update, save) MUST wp_slash() before calling any WP write function. Verified in src/Sink/PostSink.php:144 ($args = \wp_slash($args);), PostSink.php:183 (\wp_update_post(\wp_slash($args), true)), PostSink.php:191 (\update_post_meta($postId, $key, \wp_slash($value))).

The mirror trap on the projection side: toArgs/toMeta MUST return raw values, NOT pre-slashed. Callers that take projections and pass them to their OWN WP write calls (wp_insert_post) would double-slash and corrupt every backslash on round-trip.

So: convenience slashes, projection does not. The two paths share SinkProjection::prepareValue (src/Internal/SinkProjection.php:193) which handles type-shaping, encryption, and DataObject unwrapping but never slashes.

Other AI-prone misconceptions:

"Asymmetric write/read is fine — encrypt on write, store as plain on read." Wrong. Every asymmetric encryption bug in Phase-8.7's OptionSink came from this pattern. If you encrypt, the matching source MUST decrypt.
"Storing a DataObject instance with update_post_meta($id, 'thing', $dto) — WP will serialize it." Technically true, but stores a class name in the DB; on class rename or removal you have unrecoverable garbage. Always project through SinkProjection::prepareValue which recurses arrays and turns nested DataObjects into plain arrays.
"I'll do my own slashing inside prepareValue." Wrong layer — projection stays raw. Slashing is the boundary concern at the WP-call site.

When to use this skill

Trigger when ANY of the following is true:

Creating a new file under src/Sink/.
Adding toArgs / toMeta / insert / update / save methods on a sink class.
Adding a saveAsX shortcut to HasWpSinks.
Reviewing a PR that calls update_*_meta / wp_insert_* directly without wp_slash().
Reviewing a PR that adds at-rest encryption to one sink without verifying the matching source decrypts.

Workflow

1. File location

Sinks live in src/Sink/. The pure projection logic (no WP calls) lives in src/Internal/SinkProjection.php — DON'T duplicate it. Your sink delegates type shaping there and adds the WP-specific calls.

2. The two-mode contract

Every sink ships TWO modes that share one projection:

Projection mode (caller drives the write):

public static function toArgs(
    DataObject $dto,
    ?array $only = null,
    bool $strict = false,
    bool $skipNullDeletes = false,
): array;

/**
 * @return array{write: array<string, mixed>, delete: list<string>}
 */
public static function toMeta(
    DataObject $dto,
    ?array $only = null,
    bool $strict = false,
    bool $skipNullDeletes = false,
): array;

toArgs returns the array shape wp_insert_<thing> / wp_update_<thing> accepts. toMeta returns ['write' => [k => v, ...], 'delete' => [k, k, ...]] — split because the meta write loop is "set non-nulls, delete nulls".

Convenience mode (sink drives the write):

public static function insert(DataObject $dto, ?array $only = null, bool $strict = false): int;
public static function update(DataObject $dto, ?array $only = null, bool $strict = false): bool;
public static function save(DataObject $dto, ?array $only = null, bool $strict = false): int;

All three internally call toArgs + toMeta, then issue WP function calls with wp_slash() applied at the boundary. save is the smart router: positive DTO id → update, otherwise insert.

3. Slashing policy — the rule that breaks every refactor

// Inside convenience methods (insert / update / save):
$args = \wp_slash($args);
\wp_insert_post($args, true);

\update_post_meta($postId, $key, \wp_slash($value));

// Inside projection methods (toArgs / toMeta):
return $args;  // RAW, no slashing

Reason (PostSink.php:32-43 docblock): "WP write pipeline calls wp_unslash() on inbound data. Without slashing, a value containing \" would round-trip to "." But the projection caller may build a payload that's already-slashed for a different reason; double-slashing corrupts equally. The split is the API contract.

4. Null = delete (the meta convention)

The sink's meta loop:

foreach ($meta['write'] as $key => $value) {
    \update_post_meta($postId, $key, \wp_slash($value));
}
foreach ($meta['delete'] as $key) {
    \delete_post_meta($postId, $key);
}

A DTO field that's null doesn't update the meta to NULL — it DELETES the meta entry. This pairs with the source's null-vs-empty distinction: a deleted-meta-key reads back as null (per the metadata_exists contract), which hydrates the DTO's parameter default.

The $skipNullDeletes flag lets a caller opt out: when the user is doing a partial update of a single field and doesn't want unrelated nulls to wipe other meta. Default behavior is "null deletes".

5. Honor `#[Encrypted]` symmetrically

The projection layer routes encrypted fields through EncryptionEngine::encrypt. Verified at src/Sink/OptionSink.php:134:

$value = EncryptionEngine::encrypt($value);

If your sink touches rich types (Secret, plain string with #[Encrypted]), EVERY write path must encrypt. The matching source's read path must decrypt. Asymmetric is worse than absent — the user puts a credential in, the user gets a credential out, but in between the DB stores plaintext.

The unit-test contract for any sink that writes #[Encrypted] fields:

Round-trip: hydrate → DTO → save (sink) → load (source) → DTO → unwrap → equals original plaintext.
Tamper probe: load the DB row directly, flip a byte, source-load → expect DecryptionFailedException.
Leak probe: dump the projected toArgs / toMeta arrays — should contain ciphertext, NOT the plaintext.

6. Add the `HasWpSinks` shortcut

Mirror src/Sink/HasWpSinks.php:36-115:

// Inside trait HasWpSinks:
public function saveAsComment(?array $only = null): int
{
    /** @var DataObject $this */
    return CommentSink::save($this, $only);
}

public function toCommentArgs(?array $only = null): array
{
    /** @var DataObject $this */
    return CommentSink::toArgs($this, $only);
}

DTO authors then write:

$dto = (new CommentDto(post_id: 5, content: 'hi'))->saveAsComment();

7. Identifier requirement for `update`

Updating without an ID is a programming error. Throw a typed exception (src/Exception/MissingIdentifierException.php is the existing one):

public static function update(DataObject $dto, ?array $only = null, bool $strict = false): bool
{
    $id = self::resolveId($dto);
    if ($id <= 0) {
        throw MissingIdentifierException::for($dto::class, 'comment_ID');
    }
    // ...
}

save() falls through to insert if id <= 0, so it doesn't throw — that's the user-facing "do the right thing" entry point.

8. Testing

Two layers, same as sources:

# Pure projection — no WP needed
vendor/bin/phpunit --filter CommentSinkProjectionTest

# Live-WP behaviour — companion plugin smoke + stress
wp better-data smoke
wp better-data stress

Smoke scenarios cover the round-trip (write a DTO, read it back, equal). Stress scenarios cover the encryption / wp_slash / null-delete edge cases against a real WP install.

Critical rules

Lives in src/Sink/. Pure projection logic stays in src/Internal/SinkProjection.php.
Two-mode contract: projection raw, convenience slashed. toArgs / toMeta return raw; insert / update / save apply wp_slash at the WP-call boundary.
Null = delete in meta. A null DTO value triggers delete_*_meta, not update_*_meta($key, null). Honor $skipNullDeletes when the caller wants a partial update.
Encryption symmetric end-to-end. If the sink encrypts a field, the matching source MUST decrypt the same field. Asymmetric ships a regression.
Project through SinkProjection::prepareValue for nested DataObject and array-of-DTO fields — recurses correctly and avoids storing class names in the DB.
Convenience methods slash; projection methods don't. Don't slash inside prepareValue — wrong layer.
update throws MissingIdentifierException without an ID. save doesn't throw — it routes to insert.
Add the HasWpSinks shortcut for natural call sites (saveAsComment, toCommentArgs). Skip for niche sinks.

Common mistakes

// WRONG — slashing in projection
public static function toArgs(DataObject $dto, ...): array
{
    $args = SinkProjection::projectForStorage($dto);
    return \wp_slash($args);  // WRONG: caller can't tell it's already slashed
}

// RIGHT — convenience slashes, projection raw
public static function toArgs(DataObject $dto, ...): array
{
    return SinkProjection::projectForStorage($dto);
}

public static function update(DataObject $dto, ...): bool
{
    $args = self::toArgs($dto, ...);
    \wp_update_post(\wp_slash($args), true);  // boundary slash
    // ...
}

// WRONG — encrypt on write, decrypt on read missing
class FooSink {
    public static function save(DataObject $dto): int {
        $value = EncryptionEngine::encrypt($plaintext);
        \update_option('foo', $value);
    }
}
class FooSource {
    public static function hydrate(string $option, string $dtoClass): DataObject {
        $stored = \get_option($option);  // WRONG: returns ciphertext, no decrypt
        return $dtoClass::fromArray(['foo' => $stored]);
    }
}

// RIGHT — symmetric
class FooSource {
    public static function hydrate(string $option, string $dtoClass): DataObject {
        $stored = \get_option($option);
        if ($parameter has #[Encrypted]) {
            $stored = EncryptionEngine::decrypt($stored);
        }
        // ...
    }
}

// WRONG — null doe

# better-data: Adding a sink

For library maintainers integrating WRITE-side support for a new WordPress data store with better-data — comment meta, attachments, custom taxonomies, plugin-specific tables. The shape is set by `PostSink` and `OptionSink`; deviating breaks the `HasWpSinks` trait API and surprises consumers who've internalized the dual projection-vs-convenience model.

Wrong direction. WordPress's write pipeline calls `wp_unslash()` on inbound data on the way to the DB. If you pass a raw value through `update_post_meta($id, $key, 'a"b')` without slashing first, WP unslashes a string with no slashes and stores `'ab'` (the `"` survives, but escaped/quoted values get mangled). Convenience methods (`insert`, `update`, `save`) MUST `wp_slash()` before calling any WP write function. Verified in [src/Sink/PostSink.php:144](PostSink.php) (`$args = \wp_slash($args);`), [PostSink.php:183](PostSink.php) (`\wp_update_post(\wp_slash($args), true)`), [PostSink.php:191](PostSink.php) (`\update_post_meta($postId, $key, \wp_slash($value))`).

The mirror trap on the projection side: `toArgs`/`toMeta` MUST return raw values, NOT pre-slashed. Callers that take projections and pass them to their OWN WP write calls (`wp_insert_post`) would double-slash and corrupt every backslash on round-trip.

So: **convenience slashes, projection does not**. The two paths share `SinkProjection::prepareValue` ([src/Internal/SinkProjection.php:193](SinkProjection.php)) which handles type-shaping, encryption, and DataObject unwrapping but never slashes.

public static function toMeta(

```

`toArgs` returns the array shape `wp_insert_<thing>` / `wp_update_<thing>` accepts. `toMeta` returns `['write' => [k => v, ...], 'delete' => [k, k, ...]]` — split because the meta write loop is "set non-nulls, delete nulls".

**Convenience mode** (sink drives the write):

```php
