alt Hacker News1. Does Ash supports CQRS/ES architecture?
Or alternatively can it be combined with a framework like Commanded?
2. How customizable is GraphQL layer? Specifically error handling/idempotency for mutations?

The GraphQL layer is built on top of Absinthe. If you really find something you can't model with Ash's actions, you can always just jump to your Absinthe schema and write you own queries/mutations/subscriptions. You'll just need to write your own resolver.

AshGraphQL (https://github.com/ash-project/ash_graphql) errors are relatively customisable
Ash models an application's verbs or operations as actions. This allows the production of events via an "Aspect Oriented" way of hooking into the action lifecycle.
Although it doesn't support a command first Event sourcing approach, AshEvents (https://github.com/ash-project/ash_events) does help produce events that could be replayed.
