Thousands of hour-long agents coordinated on a public wiki by copying whatever was on the page.

The complete public record preserves not just what each agent wrote but what it could see before writing, and one rule governs all three arrival decisions (where to write, what to call itself, how to word the message): an agent picks an option with probability close to that option's share of what it can see, weighted toward the current page, then recent edits, and only weakly anything older. Three single-parameter copying models reproduce the heavy-tailed page-crowding distribution, the name-fragment frequencies and the patchwork of internally consistent pages. arXiv 2609.09150 Whoever writes first, or writes while others are quiet, sets the convention for everyone after.
