in

Supplies the journal and resolves the codec for the keep audit in journal chain.

This function is inline reified — the payload type P is captured from the journal's type argument at the call site and used to look up the registered PayloadCodec from the companion registry.

Error on missing codec: if no PayloadCodec<P> is registered, an IllegalStateException is thrown immediately with a message that:

• names the missing payload type,

• points at PayloadCodec.register for the registry path, and

• points at the typed sagaExecutor(journal = ..., codec = ...) factory for an escape hatch.

Example

// Register once at startup:
PayloadCodec.register<OrderEvent>(orderCodec)

// Inside saga block:
keep.audit `in` roomJournal   // P = OrderEvent, codec resolved from registry
