Smith::Session::Transcript

Cutting the transcript is not a plain slice: providers reject a request where a tool_use has no matching tool_result, the same invariant Context.compact upholds.

Class methods

index_after(messages : Array(Smith::LLM::Message), id : String) : Int32 | Nil

Where the transcript has to be cut so that id is the last message left.

nil means the message is not there any more — compaction replaced it with a summary. That is a real answer, not a failure: a rewind to such a checkpoint restores its files and leaves the transcript alone, rather than guessing at a position and cutting somewhere else.
