better-data: Security-sensitive changes

For library maintainers touching anything in better-data's security perimeter — Secret, EncryptionEngine, #[Sensitive], #[Encrypted], RequestSource guards, password handling. Mistakes in this perimeter aren't bugs that show up in tests; they're regressions that ship plaintext to disk or leak credentials in logs.

Misconception this skill corrects

"I'll add a debug-mode that logs the encrypted value's plaintext when developer mode is on — it's only for development."

Don't. The security-feature-with-bypass is the worst outcome — caller assumes redaction is universal, log infrastructure picks up the "debug" path in production by accident, plaintext lands in CloudWatch / Sentry / wp-debug.log forever. The discipline is no-bypass: Secret's __toString returns '***' (src/Secret.php:84-87), jsonSerialize returns '***' (src/Secret.php:89-92), __debugInfo (controls var_dump / print_r) returns ['value' => '***'] (src/Secret.php:99-103), __serialize THROWS SecretSerializationException (src/Secret.php:105-109).

The throwing __serialize is deliberate — a caller serialized a Secret has already made a security-relevant mistake. Relaxing it to redact instead would silently let the bug ship. The exception forces them to either ->reveal() explicitly (audit point) or rethink the flow.

Other AI-prone misconceptions:

"I'll cache the encryption key in a static property to avoid re-reading the constant on every call." Wrong — EncryptionEngine deliberately re-reads on every call (src/Encryption/EncryptionEngine.php:53-54) so key rotation via BETTER_DATA_ENCRYPTION_KEY_PREVIOUS actually works. A process-long cache defeats rotation.
"== and === are fine for comparing two Secrets; the constant-time stuff is paranoia." Wrong — string compare is timing-dependent and leaks length / first-byte equality through repeated probing. Secret::equals uses hash_equals (src/Secret.php:78-82). Always.
"If decryption fails, return null and the caller falls back to the default." Wrong — silent failure on decrypt is worse than an exception. A caller that gets null instead of the expected secret may treat it as "user never set a key" and proceed. EncryptionEngine::decrypt throws DecryptionFailedException (src/Encryption/EncryptionEngine.php:109,130).

When to use this skill

Trigger when ANY of the following is true:

The diff touches src/Secret.php, src/Encryption/EncryptionEngine.php, src/Attribute/Encrypted.php, src/Attribute/Sensitive.php.
The diff touches MetaKeyRegistry::register, route-owned-field handling, or RequestSource guards.
New code introduces a Secret typed property OR #[Encrypted] attribute.
New code calls EncryptionEngine::encrypt / decrypt / looksEncrypted.
New code introduces password handling (user_pass, hash storage, comparison).
Reviewing a PR that adds a "debug mode" / "verbose log" / "for development" flag near sensitive material.

Workflow

1. Threat model first (in the PR description or a code comment)

Write down explicitly:

What is this change preventing? (e.g. "API tokens stored as plaintext in wp_options.")
What remains un-prevented? (e.g. "Plaintext key in PHP memory between hydration and use; an attacker with PHP memory access can still read it.")
What's the threat model? (e.g. "Database compromise, log file exposure. NOT defending against in-memory attackers — that requires HSM-grade key management.")

The goal: a future contributor reads the comment and knows whether their proposed change preserves or breaks the model.

2. Loud over silent

Every degradation must throw. The catalog:

Condition	Throws
Encryption key constant not defined	`RuntimeException`
`decrypt` called on garbage	`DecryptionFailedException`
`decrypt` called with tampered ciphertext (GCM auth tag mismatch)	`DecryptionFailedException`
Secret `__serialize` invoked	`SecretSerializationException`
`MetaKeyRegistry::register` collision (one key, two DTOs)	`RuntimeException`
`RequestSource::noCollision` finds an unexpected route-owned field in the body	`RequestParamCollisionException`
`strict` mode + unknown DTO field in incoming data	`UnknownFieldException`

If you add a security feature, add a corresponding throw. Don't ship a flag that converts the throw into a warning.

3. Symmetric end-to-end

Every encrypt has a matching decrypt, every redact has a matching reveal. Lookup table:

Write side	Read side
`SinkProjection::prepareValue` encrypts when `#[Encrypted]`	`AttributeDrivenHydrator` decrypts when `#[Encrypted]`
`Presenter::toArray` redacts `Secret` / `#[Sensitive]`	Explicit `$secret->reveal()` inside `compute()` closure
`OptionSink::projectForStorage` encrypts	`OptionSource` decrypts
`__serialize` throws	`__unserialize` throws — symmetric blockage

If you add an encrypt path, you MUST add the matching decrypt path in the same PR. The reverse is also true. Asymmetry is a security regression because it preserves DATA but loses CONFIDENTIALITY.

4. Never cache the raw key

The pattern at src/Encryption/EncryptionEngine.php:53-54 is:

private const CONST_PRIMARY = 'BETTER_DATA_ENCRYPTION_KEY';
private const CONST_PREVIOUS = 'BETTER_DATA_ENCRYPTION_KEY_PREVIOUS';

Each encrypt / decrypt call reads the constant fresh. NO static property holds the resolved key. Reason: rotation. The runbook is:

Define BETTER_DATA_ENCRYPTION_KEY with the new key.
Define BETTER_DATA_ENCRYPTION_KEY_PREVIOUS with the old key.
Wait for the rotation period (lazy migration: every read decrypts under the old key, every write re-encrypts under the new).
Eventually undefine BETTER_DATA_ENCRYPTION_KEY_PREVIOUS.

If you cached the key in a static, step 1 doesn't take effect until the PHP process restarts — which can be hours after the constant changes. Don't cache.

5. Constant-time comparison

Any string comparison involving secret material:

// WRONG — timing oracle
if ($candidate === $stored) { /* ... */ }

// RIGHT
if (\hash_equals($stored, $candidate)) { /* ... */ }

Secret::equals is the canonical example (src/Secret.php:78-82). For password verification, use password_verify (which is constant-time by design).

6. Unit-test contract for security changes

Three probes minimum:

public function test_tampering_throws(): void
{
    $ciphertext = EncryptionEngine::encrypt('hello');
    // Flip one byte after the bd:v1: prefix
    $tampered = substr($ciphertext, 0, 8) . 'X' . substr($ciphertext, 9);

    $this->expectException(DecryptionFailedException::class);
    EncryptionEngine::decrypt($tampered, 'field');
}

public function test_missing_key_throws(): void
{
    // ensure the constant is undefined for this test
    $this->expectException(RuntimeException::class);
    EncryptionEngine::encrypt('hello');
}

public function test_secret_does_not_leak_via_dump_or_json_or_serialize(): void
{
    $secret = new Secret('sk_live_supersecret');

    $this->assertSame('***', (string) $secret);
    $this->assertSame('"***"', \json_encode($secret));
    $this->assertStringNotContainsString('sk_live', \print_r($secret, true));
    $this->assertStringNotContainsString('sk_live', \var_export($secret, true));

    $this->expectException(SecretSerializationException::class);
    \serialize($secret);
}

Add a leak probe for any new property / class that wraps secret material. The probe should print_r / var_dump / json_encode / serialize and assert the raw value isn't present.

7. Stress scenario for the WP boundary

The companion plugin's stress suite covers live-WP behavior:

DTO hydrated from wp_options round-trips: option row contains ciphertext, hydrated DTO contains a Secret, reveal returns the original.
REST response for a DTO with Secret shows '***' (consumer never sees plaintext over the wire).
wp_options row inspection (raw SELECT) returns ciphertext, not plaintext.

wp better-data stress --filter Secret

A FAIL finding here blocks the change. A NOTE is acceptable but documented.

8. Run the full check

vendor/bin/phpunit
vendor/bin/phpstan analyse --memory-limit=1G
vendor/bin/php-cs-fixer fix
wp better-data stress

Critical rules

Loud over silent. Every security degradation throws. No "soft fail with warning", no "log and return null".
Symmetric end-to-end. Encrypt requires decrypt. Redact requires explicit reveal. New write path requires new read path.
Never cache the encryption key. EncryptionEngine re-reads the constant per call; key rotation depends on it.
hash_equals for any comparison involving secret material. == and === are timing oracles.
Secret::__serialize throws — do not relax to redact. The exception forces explicit ->reveal() (audit point) or rethink.
No "debug mode" that logs plaintext. Even conditionally. The flag inevitably runs in production.
Threat model in the PR description or a code comment. Future contributors need to know what's protected and what isn't.
Tamper probe + leak probe in unit tests for any change touching Secret / EncryptionEngine.
MetaKeyRegistry::register collisions throw. Two DTOs claiming the same meta_key is a programming error, not a coexistence-via-overwrite scenario.
RequestSource strict mode whitelist throws on unknown fields. Don't relax to "ignore unknown" — the strict mode IS the security boundary.
Constant-time comparison for password equality. Use password_verify for hashes; hash_equals for raw secret comparison.

Common mistakes

// WRONG — debug-mode plaintext logging
public function decrypt(string $ciphertext, string $field): string
{
    $plaintext = self::actualDecrypt($ciphertext);
    if (\defined('BETTER_DATA_DEBUG') && BETTER_DATA_DEBUG) {
        \error_log("Decrypted {$field}: {$plaintext}");  // INSECURE — plaintext to log
    }
    return $plaintext;
}

// RIGHT — no plaintext-leaking branches at all

// WRONG — silent failure on decrypt
public function decrypt(string $ciphertext, string $field): ?string
{
    try {
        return self::actualDecrypt($ciphertext);
    } catch (\Throwable) {
        return null;  // BUG — caller can't tell garbage data from missing data
    }
}

// RIGHT — let it throw
public function decrypt(string $ciphertext, string $field): string
{
    return self::actualDecrypt($ciphertext);
    //
