Defined in:

Overview

Read-only Flipper adapter over the client's frozen snapshot (design doc §5). HARD RULE: get/get_multi/get_all build fresh, UNFROZEN top-level hashes on every call — Flipper::Adapters::Memoizable mutates the Hash we return (response.default_proc =, memoizable.rb:103), so a frozen or shared return value would raise FrozenError on every memoized request.
