Overview

A live, dot-accessible view over a resolved configuration.

Identity-stable per config key (the same instance is returned by repeat client.config.get / get_or_create calls). Every read goes through the underlying client’s resolved-config cache, so WebSocket updates are picked up automatically — there is no subscribe step.

#get_bool(item_key, default, description: nil) ⇒ Object

Typed getters (ADR-037 §2.13)

Each registers the item (key, type, default, description) on first call within the process, then returns the resolved value. When the resolved value can’t be coerced to the getter’s type — including the “not yet set on the server” case — the in-code default is returned and a debug message is logged.
