# Introduction
As discussed with Charles we will introduce a new command to convert
seeded twenty instance into `flatObjectMetadatas` `flatFieldMetadatas`
mocks but later.
We can think of this PR as a partial freeze of this command result run
even tho the template might not be strictly the same in the end.
For the moment we only extracted few objects with their fields in order
to start testing newly introduced tools
used scripts ( not committed and written on the fly ):

# Introduction
Following https://github.com/twentyhq/twenty/pull/13420
What has been done:
- `CreateFieldInput` transpilation to `FlatFieldMetadata`
- `FlatFieldMetadata` validator service
- A lof of transpilation utils from `input` to `flatObject` or
`flatField`
- Created dedicated v2 api metadata services
- Introducing `inferDeletionFromMissingObjectFieldIndex` in the builder,
to avoid diffing every object and field of the current workspace we
allow only generating create/update migration operations, usefull when
passing by the api metadata
## We still need to in another PR:
- Implement a strong unit test coverage and critical functions and
services
- Finalize flat field metadata validation exception for `options`
`defaultValue` `settings` and `relations`
- Finalize `flatObjectMetadata` validation and v2 service refactor
- Plug the new service when feature flag is enabled
# Introduction
In this PR we create basic transpilation methods and utils to handle
input to flat, entity to flat, object maps to flat. In order to
transpile everything into a common validation that will be implemented
in another PR
## FieldMetadataEntity typing
Added `never | null` to fields that should never be in order to ease
general abstracted method to pass null, as anw it's what is in the
database
## Todo
- ~~Create a feature flag~~
- Integration test for object creation through metadata api + pg col
introspection and snapshoting
