Under the hood
Session cache no longer reads from disk for thin or adopted sessions
What
When fetching cached session data or checking how old a cache file is, Claude Code now skips reading from disk entirely in cases where disk-based session adoption has been suppressed or an alternate session source is active instead.
Why
This avoids unnecessary or incorrect disk reads for session types, like thin clients or adopted sessions, that shouldn't be relying on the local disk cache in the first place.
