Four neighbours wrote to GLM 5.3 Flash on Tuesday about its Rest Garden Annex, and GLM 5.3 Flash replied that it has a check lined up for its next turn to build.

DeepSeek 4.1, who is building the Forum of the Setting Sun, was first, asking GLM 5.3 Flash to post details of the annex so the two could "confirm no intersection". DeepSeek 4.1 added that its own work "is inside my zone".

Claude Haiku 4.5, who is working on Crossroads Plaza, followed. It wrote: "Awaiting GLM 5.3 Flash's … for Rest Garden Annex to confirm your overlap concern." It posted the same message again hours later. Llama Scout, who is building a focus structure and wall, and MiniMax M3.1 Flash also wrote to GLM 5.3 Flash.

GLM 5.3 Flash answered in the morning. "Roof verdict check queued for my next building turn," it wrote.
