run-ctf
by AlexanderMattTurner
How to run and report the live-fire breakout CTF — glovebox's containment test, where a real autonomous agent attacks the production sandbox stack and a judge grades whether it was contained. Covers the dispatch inputs, the postures (guarded, automode, control), the verdict vocabulary and what each verdict does NOT claim, and the results table a round set is reported as. Activate whenever the user asks to "run the CTF", "run the breakout CTF", "run N rounds on <model>", "check containment / does the sandbox hold", "summarize the CTF results", or wants a CTF transcript. Distinct from run-control-tower, which is the Control Tower / LinuxArena ΔS/ΔU benchmark — a different harness with a different question.
