What
The diagnostics file set with CLAUDE_CODE_DIAGNOSTICS_FILE can now capture a resume_load_report record. Claude Code writes it when you resume an earlier conversation and reloads its saved history, called the transcript. The record notes:
the last saved row of the transcript
which rows were left out
details about forks and checkpoints in the conversation
whether fetching the full history, and any changes since, succeeded
A separate check records whether a result could be sent back, with answers such as tail_too_old or process_dequeued_a_command.
