The Regexta application implements a functional state logic that regulates the behavior of the interface and guarantees consistency between input and generated output.

State management is strictly connected to the regestum extraction process.

The “Editable” state represents the initial condition of the document.

At this stage:

• the user may freely insert or modify the text;
• it is possible to upload or replace a file;
• it is possible to select or modify the document type (Document Type);
• the output has not yet been generated.

The document remains in this state until execution of the “Extract Regestum” command.

After the extraction process is started, the document enters the “Extracted” state.

At this stage:

• the input area becomes read-only;
• the text can no longer be modified;
• the structured output is generated and displayed;
• output operations become available (Export, Copy, Save for authenticated users).

The transition to the “Extracted” state guarantees integrity between the analyzed content and the produced regestum.

The transition between states occurs according to the following rules:

• from “Editable” to “Extracted” through the “Extract Regestum” command;
• from “Extracted” to “Editable” through the “Reset” command.

The “Reset” command clears:

• the input content;
• the generated output;
• the read-only state.

The system therefore returns to the initial configuration, allowing a new processing cycle.

The application applies differentiated visibility and persistence rules according to authentication status.

Non-authenticated user:

• cannot save regesta within the platform;
• does not see the “Collections” page;
• may only export the result locally.

Authenticated user (Researcher):

• may save the generated regestum;
• may associate it with a Collection;
• may access the “Collections” page;
• may consult previously archived documents.

Admin:

• has full access to the contents and functionalities of the application.
