Conversation
Add a "custom" fork option that reveals a Python-DSL textarea for defining ad-hoc SSZ containers using consensus-specs syntax. Lets users serialize/ deserialize types from unreleased forks or one-off shapes without waiting for them to land in @lodestar/types. Parser accepts multiple `class Foo(Container):` blocks, resolves field type idents against forks.fulu and built-in primitives (uint8..256, boolean), and accepts either integer literals or @lodestar/params constants for List/Vector/Bitlist/Bitvector/ByteList/ByteVector sizes. Compilation runs in both main thread (for the UI Type instance) and the worker (for serialize/deserialize), debounced 300ms. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
