Using a JSON field as an id
Hello! I want to cache API results in the database and I was wondering if it'd be possible to use the id in the JSON field as an id, perhaps through @@id or some client extension?

Type definitions must be strings or objects (was undefined)
Hello! When importing a module that is using Arktype, I get the error Type definitions must be strings or objects (was undefined). I am not sure what it means. What should I be looking for to solve it?

Conform to an existing type
Hello! Is there a way to force a def to conform to an existing typescript type? 
export const chatDef = type({
    id: 'number',
    chatType: "private' | 'public'",
    title: 'string',
    username: 'string'
  // force this
}) satisfies Pick<Jsonify<Chat>, 'id' | 'chatType' | 'title' | 'username'>
export const chatDef = type({
    id: 'number',
    chatType: "private' | 'public'",
    title: 'string',
    username: 'string'
  // force this
}) satisfies Pick<Jsonify<Chat>, 'id' | 'chatType' | 'title' | 'username'>

Node of kind optional is not valid as a required definition
Hello! Whenever I use a type with an optional key with a default value like this: 
const def = type({
    'agree?': 'boolean = true',
})
const def = type({
    'agree?': 'boolean = true',
})
I get the error Node of kind optional is not valid as a required definition. What could it mean? Note that I'm also updating the type via map, but removing that mapping appeared to have no effect so far. Removing the default value throws no error

ParseError: undefined must be a PropertyKey or stringifyNonKey must be passed to options
Hello! When key isn't provided in the .map function, the above error is thrown. Not working code: 
const mapTypes = <T extends typeof typee>(t: T) =>
    t.map((prop) => {
        const key = prop.key
        const value = prop.value

        if (value.extends(type.number)) {
            return [prop, { value: value.or('string.numeric.parse') }]
        }

        if (value.extends('boolean')) {
            return [prop, { value: value.or(['string', '=>', (v) => v === 'on']) }]
        }

        return prop
    })
const mapTypes = <T extends typeof typee>(t: T) =>
    t.map((prop) => {
        const key = prop.key
        const value = prop.value

        if (value.extends(type.number)) {
            return [prop, { value: value.or('string.numeric.parse') }]
        }

        if (value.extends('boolean')) {
            return [prop, { value: value.or(['string', '=>', (v) => v === 'on']) }]
        }

        return prop
    })
Working code (simply added key to return object): 
const mapTypes = <T extends typeof typee>(t: T) =>
    t.map((prop) => {
        const key = prop.key
        const value = prop.value

        if (value.extends(type.number)) {
            return [prop, { key, value: value.or('string.numeric.parse') }]
        }

        if (value.extends('boolean')) {
            return [
                prop,
                { key, value: value.or(['string', '=>', (v) => v === 'on']) },
            ]
        }

        return prop
    })
const mapTypes = <T extends typeof typee>(t: T) =>
    t.map((prop) => {
        const key = prop.key
        const value = prop.value

        if (value.extends(type.number)) {
            return [prop, { key, value: value.or('string.numeric.parse') }]
        }

        if (value.extends('boolean')) {
            return [
                prop,
                { key, value: value.or(['string', '=>', (v) => v === 'on']) },
            ]
        }

        return prop
    })
Is there a reason for this behavior? I would expect the key to already be present on the prop

Dynamic type based on another value
Given a theoretical example like this: 
const formDef = type({
    agree: 'boolean',
    clauses: ['===', 'first', 'second'],
})
const formDef = type({
    agree: 'boolean',
    clauses: ['===', 'first', 'second'],
})
Is it possible to only have clauses be required if agree is true?

Extracting defaults at runtime
Hello! What is the canon way to extract the default values of the type on runtime? I'd like to uuse the defaults from the type as defaults in a form. 
const formDef = type({
    cars: '5 < number < 100 = 50',
    name: ['string[]', '=', []],
    active: 'boolean = true',
})

<Form
    defaultValue={
        // ...defaults from formDef
    }
>
const formDef = type({
    cars: '5 < number < 100 = 50',
    name: ['string[]', '=', []],
    active: 'boolean = true',
})

<Form
    defaultValue={
        // ...defaults from formDef

Extracting intent into runtime
Hello! What is the canon way to extract keys from types like these: 
const type1 = type({
  intent: '"hello"',
 })

const type2 = type({
  intent: '"hello"',
}).or({
  intent: '"bye"',
})
const type1 = type({
  intent: '"hello"',
 })

const type2 = type({
  intent: '"hello"',
}).or({
  intent: '"bye"',
})
In a way that the resulting object is 
{
  intent: {
    hello: 'hello'
  }
}

{
  intent: {
    hello: 'hello',
    bye: 'bye'
  }
}
{
  intent: {
    hello: 'hello'
  }
}

{
  intent: {
    hello: 'hello',
    bye: 'bye'
  }
}
? Would it be achieved with internal.distribute?

Converting Zod to Arktype
Hello! I'm really interested in using Conform instead of React Hook Form for better DX and server-side capabilities. However, it doesn't have Ark support yet, so I'll have to create my own simple patch. Are there by any chance some examples or comparisons between Zod and Arktype architectures to go off of when translating these files, namely to extract the name of the constraints like Array in runtime? expression might be "key"? pun intended https://github.com/edmundhung/conform/blob/main/packages/conform-zod/constraint.ts https://github.com/edmundhung/conform/blob/main/packages/conform-zod/parse.ts Also, is there an way to do something like superRefine for custom run-time conditions? https://zod.dev/?id=superrefine

Default number
Hello! Setting this brings the expected result, when ran through inferAmbient: 
const queryType = type({
    page: 'number',
})

// Result:
number
const queryType = type({
    page: 'number',
})

// Result:
number
But adding a default value returns a function signature: 
const queryType = type({
    page: 'number = 1',
})

// Result
page?: ((In?: number | undefined) => Default<1>) | undefined
const queryType = type({
    page: 'number = 1',
})

// Result
page?: ((In?: number | undefined) => Default<1>) | undefined
How can I get the number type in the editor when providing a default value?

Accept number in string type
Hello! I'm parsing each value in a form with JSON.parse to convert string values like false to actual booleans. Unfortunately, this introduces the issue, that if someone inputs 123 into a text field, it gets parsed into a number type by JSON.parse. Then if the field is type string. An error is thrown, since number is not assignable to string. How should a type look like, if it should handle such a situation?

Extract type from or
Hello! Is it possible, using the following schema: 
const userType = type({
    intent: "'profile'",
    name: 'string>0',
    surname: 'string>4',
})
.or({
    intent: "'private'",
    password: 'string>0',
})
const userType = type({
    intent: "'profile'",
    name: 'string>0',
    surname: 'string>4',
})
.or({
    intent: "'private'",
    password: 'string>0',
})
to extract one of the types ("find" it by the intent field)? I'd like to use it for multiple forms on a page. It's possible to split it into multiple types, but having it in one type is more readable to me

Get type without constraints
Hello! inferAmbient retuns types with constraints like moreThanLength<0>, which when I try to access values to, I get Type 'string' is not assignable to type 'moreThanLength<0>'. Is it possible to extract a more basic type?

must be an instance of FormData (was object)
Hello! This code: 
const formData = await request.clone().formData();

const formSchema = type({
    name: 'string>0',
    surname: 'string>0'
})

const parseForm = type('parse.formData').pipe(formSchema)

const formResult = parseForm(formData)
const formData = await request.clone().formData();

const formSchema = type({
    name: 'string>0',
    surname: 'string>0'
})

const parseForm = type('parse.formData').pipe(formSchema)

const formResult = parseForm(formData)
Throws following error: 
must be an instance of FormData (was object)
must be an instance of FormData (was object)
However, formData is instanceof FormData and the log also says it's FormData: 
ArkError {
  input: {
    code: 'proto',
    description: 'an instance of FormData',
    proto: [class FormData]
  },
  ' arkKind': 'error',
  path: [],
  data: FormData { name: 'Plat', surname: '' },
...
ArkError {
  input: {
    code: 'proto',
    description: 'an instance of FormData',
    proto: [class FormData]
  },
  ' arkKind': 'error',
  path: [],
  data: FormData { name: 'Plat', surname: '' },
...
What am I doing wrong?

Error internationalization (i18n)
Hello! Is it possible to translate the errors into other languages? In my previous setup I was using this for such funtionality: https://github.com/aiji42/zod-i18n I saw this issue opened for individual fields, which would really be great: https://github.com/arktypeio/arktype/issues/722 Is this the way for "general" errors? https://github.com/arktypeio/arktype/issues/404

Tried to initialize an $ark registry in a monorepo
Hello! In a pnpm workspace, I have 2 packages depending on arktype. This means that each package depends on arktype separately. However, when I import them into a central vite project, I get the error: 
Tried to initialize an $ark registry but one already existed. This probably means you are either depending on multiple versions of an arktype package, or importing the same package from both ESM and CJS.
Review package.json versions across your repo to ensure consistency.
Tried to initialize an $ark registry but one already existed. This probably means you are either depending on multiple versions of an arktype package, or importing the same package from both ESM and CJS.
Review package.json versions across your repo to ensure consistency.
Both packages are compiled to ESM, and the arktype version is identical, so the issue must be in them clashing inside of the vite project. What would be a good way to avoid this error?
