How to use reject correctly?
But I specified actual in reject. 
actual: `${(data.size / 1024 / 1024).toFixed(2)}MB`,
actual: `${(data.size / 1024 / 1024).toFixed(2)}MB`,

Okay. Why is the actual not the one I specified in reject, but the default one? Am I misunderstanding how this is supposed to work?

The code above works without exception, only the error texts are not what I expect and there is no custom actual. But if I remove expected from reject in the code above, I get an exception. I will add min repo later

How to use reject correctly?
I did this 
export const schema = type({
  name: type("string > 0"),
  phone: "string",
  "files[]?": type("File | File[] < 6").narrow((data, ctx) => {
    const MAX_SIZE = 4 * 1024 * 1024;

    if (Array.isArray(data)) {
      const totalSize = data.reduce((sum, file) => sum + file.size, 0);
      if (totalSize > MAX_SIZE) {
        return ctx.reject({
          actual: `${data.length} files, ${totalSize} bytes total`,
          expected: `Total files size should be less than 4MB`,
        });
      }
      return true;
    }

    if (data.size > MAX_SIZE) {
      return ctx.reject({
        actual: `${(data.size / 1024 / 1024).toFixed(2)}MB`,
        expected: "File size should be less than 4MB",
      });
    }

    return true;
  }),
}).onUndeclaredKey("delete");
export const schema = type({
  name: type("string > 0"),
  phone: "string",
  "files[]?": type("File | File[] < 6").narrow((data, ctx) => {
    const MAX_SIZE = 4 * 1024 * 1024;

    if (Array.isArray(data)) {
      const totalSize = data.reduce((sum, file) => sum + file.size, 0);
      if (totalSize > MAX_SIZE) {
        return ctx.reject({
          actual: `${data.length} files, ${totalSize} bytes total`,
          expected: `Total files size should be less than 4MB`,
        });
      }
      return true;
    }

    if (data.size > MAX_SIZE) {
      return ctx.reject({
        actual: `${(data.size / 1024 / 1024).toFixed(2)}MB`,
        expected: "File size should be less than 4MB",
      });
    }

    return true;
  }),
}).onUndeclaredKey("delete");
in server action i have this 
    const data = type("FormData.parse").pipe(schema)(formData);
    if (data instanceof type.errors) {
      console.dir(data.flatProblemsByPath);
      return {
        status: "error",
        message: "Form validation failed",
        errors: data.flatProblemsByPath,
      };
    }
    const data = type("FormData.parse").pipe(schema)(formData);
    if (data instanceof type.errors) {
      console.dir(data.flatProblemsByPath);
      return {
        status: "error",
        message: "Form validation failed",
        errors: data.flatProblemsByPath,
      };
    }
when i upload file with 5MB console.dir(data.flatProblemsByPath) prints 
{
  email: [ 'must be an email address' ],
  name: [ 'must be non-empty' ],
  '["files[]"]': [
    '["files[]"] must be File size should be less than 4MB or an array (was File)'
  ]
}
{
  email: [ 'must be an email address' ],
  name: [ 'must be non-empty' ],
  '["files[]"]': [
    '["files[]"] must be File size should be less than 4MB or an array (was File)'
  ]
}

That is, I want to get an error if it is not a file or an array of files, and also get an error on the size of the files

How to use reject correctly?
with this code it works 
 return ctx.reject({
      message: "File size should be less than 4MB",
      actual: `${(data.size/1024/1024).toFixed(2)}MB`,
      expected: "File size should be less than 4MB",
    });
 return ctx.reject({
      message: "File size should be less than 4MB",
      actual: `${(data.size/1024/1024).toFixed(2)}MB`,
      expected: "File size should be less than 4MB",
    });
but console.dir(data.flatProblemsByPath) shows me 
  '["files[]"]': [
    '["files[]"] must be File size should be less than 4MB or an array (was File)'
  ]
  '["files[]"]': [
    '["files[]"] must be File size should be less than 4MB or an array (was File)'
  ]
without narrow errors looks different 
 '["files[]"]': [ 'must be a string (was an object)' ]
 '["files[]"]': [ 'must be a string (was an object)' ]
(I changed the type on purpose to get the error)

Easy format errors like in Zod?
Yes, I think you're right, there is no one-size-fits-all option) I'm just speculating based on other examples

Yes I realize that, but it can be necessary and valid, as an example in laravel https://laravel.com/docs/12.x/validation#validation-error-response-format.

looks cool!. Can the second method be added just in case, like flatMessageByPath?

Easy format errors like in Zod?
I just gave an example above, it is not about the error text itself, but about the format. I need write this code to format errors like in zod to get this { email: [ 'email must be an email address (was "")' ], message: [ 'message must be non-empty' ], name: [ 'name must be non-empty' ] } if (data instanceof type.errors) { const formattedErrors: Record<string, string[]> = {}; for (const problem of data.issues) { const field = problem.path.stringify(); if (!formattedErrors[field]) { formattedErrors[field] = []; } formattedErrors[field].push(problem.message); } console.dir(formattedErrors) }

I need to show validation errors under each input. I'm just saying that I need to go through the object, pull out the error text and compose it into an array. Zod has a built-in method for this. I think this is a common use case, no?

Yeah, I've seen it and I've watched it. But it's not quite the same. I often need this format for api response errors: { email: ['invalid email, 'spam mailbox'] }
