Type player.data Keys

Each player carries a small key/value store at player.data. Augment CustomizablePlayerStorage to declare its keys and value types — get and set then autocomplete and type-check against your schema.

Declare the schemaCopy Anchor Link

await player.data.set('enabledAutoplay', true);

const enabled = await player.data.get('enabledAutoplay');
       
const enabled: boolean | undefined

get returns V | undefined for the key's declared type — here boolean | undefined — so unset keys are handled at the type level.

Keys starting with internal_Copy Anchor Link

Hoshimi keeps its own bookkeeping under internal_-prefixed keys, and those are hidden from every enumeration (keys(), values(), entries(), all()). Don't declare or write them — treat that prefix as reserved.
