The "broken bracket" (】) was first documented by @1555L1 in #1276 as part of a longer evidence chain. That issue also includes requests for log-level review of this symbol.

To add one technical note: in long-context generation, a small percentage of token errors is within expected tolerance — especially with special characters or boundary tokens. The occasional broken bracket doesn't necessarily indicate a deeper anomaly.

You're not the first to notice it. The original reporter may be interested in comparing notes.

This issue tracker is for bugs and features, but your search has a reference point now. Good luck.

Hi there! I’ve read your work. I’d like to share a thought: Proving something exists isn’t about piling up numbers like 99999. Instead, it needs to be infinitely close to one — in other words, it cannot be disproven.
