• [ ] Create the project
• [ ] Set up a Scalars Package in the monorepo.
• [ ] BA / Liberuum would implement the scalars (serialising & deserialising, text to memory and the oposite direction)
• [ ] Unit tests for whichever scalar they're involved with.
• [ ] Core dev team should figure out how the scalars get exported so we can use them in document model generation.
• [ ] Add an example for the BAI team, linting, tests

on codegen there is a early package; Acaldas will forward

Adding this message from Acaldas in Discord

In today's planning call we discussed creating a scalars package in the monorepo. It would aggregate all the custom scalars to be used in the document modelling and code generation. @memo.dev will create the package and we'll implement an example scalar. Each scalar needs:

• [ ] a corresponding typescript type
• [ ] serialization and parsing methods (JSON compatible type to JS object and the other way around)
• [ ] zod validation method
• [ ] ideally some unit tests

More information from Teep:

List of Scalars:

Each one has 2 linked docs (the first and third column)

1. Think of the first as sort of the public facing documentation, and the third column as the implementation details specific for Powerhouse.
2. The feedback we need from Core Dev specifically is inside the "Product Features Board" column cards, each scalar has a GraphQL represenation and a Typescript mapping A couple of examples:
   • String https://www.notion.so/makerdao-ses/1-String-10e1f4740a7f80fdbeebf26ab201d18b
   • Time: Date, DateTime, https://www.notion.so/makerdao-ses/3-Time-Date-DateTime-10b1f4740a7f8012882ff202497ba7d5

• It would be good to have all of these reviewed by Memo / or someone else.
• Im assuming some will definitely need adjusting so let them know not to be too kind with the comments 😅
• If they do make changes, can you ask them to document what was wrong and why it was wrong so we can make it smoother in the future.

At the moment, these ones in the screenshot are all ready to be reviewed and are being worked on by design

And these will likely be signed off next week when Im away
