Drawn as four walls the agent's path meets: it passes the first, jumps the second, breaks the third, and stops at the fourth. Then Claude Code on your own machine: turn its confirmations off and one barrier moves, and not one number does. Not part of the talk: an experiment for the review. Which kinds count as a control ("not a control", "a control: holds") is abp.sgit.ai's own reading, as the data file's note on the barrier kinds says; the four kinds and their meanings are the upstream pack's. Every word, count and label is read at load from the studio's data: the barrier kinds, the enforcer test and the two Claude Code examples from `abp-examples.json`, the plain label of the row that moves from `capabilities.json`. Which barrier moves is computed by comparing the two examples' rows. Published drafts from one author's network, derived (0 of 22 rows measured); no score and no rating.
