Summary
Extend
/branchto continue after committed assistant messages and tool-result boundaries, in addition to editing earlier user prompts. Assistant and tool checkpoints retain the selected item and open an empty draft for the next user message.Motivation
Builds on #115 toward message-level transcript navigation without discarding alternate futures.
Impact
Only a result that closes its complete tool-call batch is eligible; partial batches, orphan or duplicate results, and invalid ordering are rejected. Before-user checkout and its original-prompt prefill remain unchanged.
Technical details
Exact continuation prefixes
An ordered validator checks call/result structure without repairing, reordering, or borrowing later context. The existing historical address, provisional checkout, durable completion, and retry pipeline is reused without changing persistent lineage metadata.
Role-aware selection
The chooser labels User, Assistant, and Tool checkpoints and supports role filters. Roles are additive on the private response shape, with missing legacy values interpreted as User; preview text remains separate from the editable draft.
