# Rewrite Checkpoints: Faithful Prompt + Metadata Replay (Review)

- Split the stored prompt blob back into the original prompt list via SplitPromptContent instead of wrapping it in a one-element slice — so an empty prompt file stays empty and RedactedJoinedPrompts reconstructs the original prompts (and count) rather than re-redacting the joined text. [cursor]
- Forward the remaining session-level fields the replay dropped — Attribution, PromptAttributions, SessionMetrics, Kind, ReviewPrompt/Skills, Investigate run/topic, and the root HasReview/HasInvestigation flags — so a rewritten ref matches the branch checkpoint the tool evaluates. [cursor]
