Crdt Effect

The Crdt effect provides the following built-in operations, wired into the VM and runtime.

Operation	Signature	Description
Crdt.increment	increment(field: String) -> Unit	Increment the current actor’s CRDT-backed counter field (gcounter/pncounter). The op-set guard rejects other CRDT types (nil); nil also outside an actor.
Crdt.decrement	decrement(field: String) -> Unit	Decrement the current actor’s pncounter field. Rejected (nil) on any other CRDT type; nil also outside an actor.
Crdt.add	add(field: String, item: String) -> Unit	Add an element to the current actor’s CRDT set field (gset/orset/aworset). Rejected (nil) on any other CRDT type; nil also outside an actor.
Crdt.remove	remove(field: String, item: String) -> Unit	Remove an element from the current actor’s CRDT set field (orset/aworset). Rejected (nil) on any other CRDT type; nil also outside an actor.
Crdt.set	set(field: String, value: String) -> Unit	Write a value to the current actor’s CRDT register field (lwwregister/mvregister). Rejected (nil) on any other CRDT type; nil also outside an actor.
Crdt.read	read(field: String) -> Int | String	Read the current actor’s CRDT field materialized value: the count for counters, the element count for sets/RGA, and the stored string for lwwregister (nil on a missing field or outside an actor).
