Building the context attached to a submitted prompt is now an async, storage-aware step

What

When you submit a prompt, Claude Code attaches any context items (like referenced files) to the message. That attachment step now runs through a new async helper that has access to the session's storage layer (storageV5), instead of reading the context synchronously.

Why

This suggests context items can now be fetched or hydrated from storage before being attached to a prompt, rather than only using whatever was already loaded in memory. For users this should be invisible beyond potentially more complete or up-to-date context being included with a submitted prompt.

The writer flagged doubtThe finding does not say what practical difference this makes beyond enabling async/storage-backed resolution of context items.
