What's Changed
Removed
- Legacy context window fallback code — transcript parsing,
context_na_messagesegment,build_na_line(), andfallbackoption forpercentage/tokenssegments have been removed. Claude Code now providesused_percentagereliably, making these mechanisms unnecessary. Ifused_percentageis missing, the status line produces no output instead of showing an N/A fallback.
