Module finalterm 

Shell-integration prompt and command markers using OSC 133.

Category

OSC 133 marks prompt start, command input start, command execution, and command completion. Terminals can use these markers to segment scrollback.

OSC framing

Writers use 7-bit OSC with BEL termination: ESC ] 133 ; <mark> [;data] BEL. write_finalterm is the generic form; the other functions encode the standard A, B, C, and D markers.

Mode interaction

These markers are not controlled by a DECSET mode. They are passive metadata embedded in the output stream.
