OSC 633;D command finished
ESC ] 633 ; D ; exitcode BELOSC 633;D marks command completion and includes the exit code as a parameter, mirroring OSC 133;D. The format is OSC 633 ; D ; exitcode BEL.
This is the marker that drives VS Code's command decoration gutter: green check for success (exit 0), red X for failure (non-zero exit). It's also what enables the run-recent-command picker to filter by success/failure status, and what gives the terminal command duration data for performance analysis.

OSC 633 ; D ; 0 BEL and verify the terminal consumes the sequence (cursor doesn't advance, terminal remains responsive).The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
