Br Audit Enrichment

better-route: Audit enrichment

Use audit enrichment when the standard route/method/status/duration event is not enough to debug or review sensitive operations.

Pattern

use BetterRoute\Middleware\Audit\AuditEnricherMiddleware;
use BetterRoute\Middleware\Audit\AuditMiddleware;

$router->middleware([
    $jwt,
    new AuditEnricherMiddleware([
        'resource' => 'account',
        'action' => 'update',
    ]),
    new AuditMiddleware($logger),
]);

AuditEnricherMiddleware writes safe fields to RequestContext::$attributes['audit']. AuditMiddleware merges that array into success/error events.

Fields

The enricher can add:

• authProvider
• authUserId
• authSubject
• idempotencyKey as sha1(raw-key), not the raw header
• optional clientIp
• static fields passed by the route, group, or integration

Rules

• Run auth before audit enrichment if auth fields are needed.
• Hash idempotency keys; do not log raw keys.
• Keep payment tokens, card data, secrets, cookies, bearer tokens, and full request bodies out of audit events.
• Add stable domain fields such as resource, action, and public-safe resource IDs.
• Use a private logger destination. Client error responses stay scrubbed; audit logs can be more useful but still need redaction.
