Why: workspace writes had no checkpoint, and a 5xx before any output stopped the turn instead of trying the next configured model. Evidence: GOWORK=off go test ./internal/runtime/ ./internal/runmgr/ ./internal/tools/ ./internal/settings/ ./internal/server/ ./internal/app/ Impact: models.chat.fallbacks defaults to empty, so existing runs keep their model. Rewind restores only tracked writes and appends a system note. Usage records the model that served. Refs: feature/durable-rewind Co-authored-by: Cursor <cursoragent@cursor.com>
