Dirty records

They are local IndexedDB records whose metadata has: __dirty__: true

Meaning: the client has a local change that has not been safely acknowledged by the server yet.

Examples:

• You create a row offline: metadata = { uid, created_at, __dirty__: true, __operation__: 'create' }

• You update a row offline: metadata = { uid, created_at, updated_at, __dirty__: true, __operation__: 'update' }

• You delete a row offline: metadata = { uid, created_at, deleted_at, __dirty__: true, __operation__: 'delete' }

Once the server confirms the mutation, the client stores: __dirty__: false Dirty metadata is durable in IndexedDB. If the browser closes before sync succeeds, the mutation is still remembered and retried later.
