Transcript replay's pass-2 loader rewritten to track messages by assistant/run-link ancestry
The internal logic used when loading or replaying a saved conversation transcript (pass2) was substantially rewritten. It now decides whether to include each line of the transcript by tracing back to its nearest "assistant" message and tracking "runLink" entries through helper functions, rather than using a flat list of offsets as before.
This is an internal rework of how transcripts are reconstructed; it changes how the loader determines what belongs together in a conversation, which affects the accuracy of transcript replay rather than anything directly visible in the UI.
The finding does not say what behavior difference, if any, this produces for a user.
