Issue: Potential Resource Leak in runLoad

The use of autocannon.track(instance) within the promise does not guarantee that the instance is properly cleaned up after the test completes. If the instance is not destroyed or closed, it may lead to resource exhaustion, especially when running multiple tests in sequence or under high concurrency.

Recommendation:
Ensure that the autocannon instance is properly destroyed after the test completes. You can do this by calling instance.stop() or similar cleanup logic in the callback, regardless of success or error:

const instance = autocannon(options, (err, result) => {
  instance.stop(); // Ensure cleanup
  if (err) {
    reject(err);
  } else {
    resolve(result);
  }
});

This will help prevent resource leaks and improve test reliability.

Format Validators May Not Fully Cover Edge Cases

The custom format validators for email, uuid, uri, and date-time use regular expressions and logic that do not fully comply with their respective standards (e.g., RFC 5322 for email). This can lead to false positives or negatives in validation, reducing the reliability of the test suite. For example, the email regex is simplistic and may not handle all valid/invalid emails, and the URI validator may accept non-HTTP/HTTPS schemes.

Recommendation: Consider using more robust validation libraries (such as validator.js) for format registration, or document the limitations of these validators to avoid confusion about what is actually being tested.

Optional and Nullable Type Handling Is Version-Dependent

The tests for optional and nullable types in object context (lines 364-373) are correct for the current TypeBox behavior, but TypeBox's handling of t.Optional and t.Null can be subtle and may change in future versions. If TypeBox changes its semantics, these tests could become misleading or fail unexpectedly.

Recommendation: Monitor TypeBox release notes for changes in optional/nullable semantics and update these tests accordingly to ensure continued correctness.

Ambiguous Ownership Handling

Passing ownerId: user?.id || "" may result in projects with an empty string as the owner if the user is unauthenticated. This can lead to ambiguous or invalid ownership records in the database. It is recommended to explicitly set ownerId to null (or omit the field) when unauthenticated, and ensure the service layer and database schema handle this case appropriately:

ownerId: user?.id ?? null

This approach makes the intent clearer and avoids potential issues with empty string values.

Lack of Validation for Arbitrary Object Fields

The settings and metadata fields are accepted as arbitrary objects (t.Record(t.String(), t.Unknown())) and passed directly to the service. Without additional validation or sanitization, this could allow storage of unexpected or malicious data. It is advisable to implement stricter validation or sanitization for these fields, or ensure the service layer enforces constraints to prevent injection or data integrity issues.

Issue: Error Handling Robustness

The error handling in the portrait generation logic assumes that result.error.value will always be present and have either a message or summary property. If the API response structure changes or is malformed, this could result in an uninformative error being thrown.

Recommendation:
Add explicit checks for the existence of result.error.value and its properties before accessing them. Provide a clear fallback error message if these are missing.

if (result.error) {
  const errorMsg = result.error.value?.message || result.error.value?.summary || JSON.stringify(result.error) || "Failed to generate portrait";
  throw new Error(errorMsg);

Issue: Base64 Extraction Safety

The code assumes that base64data.split(",")[1] will always yield a valid base64 string. If reader.result is not a valid data URL, this will be undefined, potentially causing the backend to receive invalid data.

Recommendation:
Validate that the split result contains the expected base64 string before proceeding. If not, handle the error gracefully.

const parts = base64data.split(",");
