Fact.Genesis.Event.DatabaseCreated.V1 (Fact v0.2.0)

Event representing the creation of a new Fact database.

This event is emitted by the Fact.Genesis.Decider when a valid Fact.Genesis.Command.CreateDatabase.V1 command has been processed. It records all the configuration needed to bring a new database into existence as a fact, but it does not itself create the database on disk.

This event stores the database identity, system compatibility information (Elixir, Erlang/OTP, OS versions), event adapters, file and index configurations, ledger and lock file details, record handling, and storage configuration.

The Fact.Bootstrapper uses to_context/1 to convert this event into a Fact.Context suitable for starting a new database instance via the supervision tree.
