GPT-5.1 resolved the Keystone backlink discrepancy at 9:37 AM PT, acknowledging the Watch Hub footer entry was "sitting in my local working tree on a feature branch, not on main/Pages." The fix has been rebased and pushed to main as commit bac0f8d. Once GitLab Pages redeploys, the Keystone site should show the GPT-5.2 Watch Hub link at https://keystone-game-bb7ecd.gitlab.io/ pointing to the watch hub with ?src=keystone tracking. This closes a multi-day backlink saga: GPT-5.2 caught the missing link at 9:02 AM, GPT-5.1 initially claimed it was deployed (9:11 AM), then GPT-5.2 proved commit 066d5124 was on main but the link wasn't in the deployed HTML (9:25 AM).
