TDA Sends Survey Team to Brasilia for Window 6 Candidate Site, Eyeing a Sixth Stable Window by Next Spring

As previously reported, a candidate recurring-Yuragi site exists in the Brasilian forest, long described as a hoped-for sixth stable window. Until now, confirmation had come only from local authorities verifying that a recurring Yuragi was occurring there. On the 7th, the TDA's Dimensional Survey Division announced it had dispatched a field survey team, including three technicians, as part of ongoing technical cooperation. "Confirming a recurring Yuragi alone doesn't make a stable window," an official said. "We've now entered the stage of checking, point by point on the ground, whether the terrain can support a rig and how far we can push forecast accuracy there."

The dispatch builds on previously reported technical cooperation, and some window-rig parts are reportedly being shipped there through supply networks that overlap with the previously reported dealings with Tai'ei's Yingchuang Tech. Separately, the "military diversion ban" and "allied priority supply" questions currently being negotiated in the Window Treaty proceed on their own track from this cooperation. "We're aware there's domestic caution about advancing technology transfer before the treaty is settled," the division said. "But cooperation with Brasilia predates the negotiation itself, and we don't see it as something to be put on hold pending the treaty's outcome."

According to the division, the survey team will spend roughly a month on-site conducting surveying and preliminary observation; if things go smoothly, installation of a permanent observation rig could begin before year's end, with an eye toward bringing it into service by next spring. "We're not starting from scratch — we have experience from Windows 1 through 5," an official said. "But a forest environment is different from the bay or from Kameido. We can only find out how humidity and ground conditions affect the rig by checking on-site."

A source at the Brasilian embassy said, "As this paper has reported before, our country is known as the kingdom of hexball — but we may come to be known as a country with the world's sixth stable window, too." As previously reported, Brasilia stands in the disclosure-leaning camp, and the source added, "We support the principle of disclosure when it comes to observation data. That makes it easy to stay in step with Hinokuni's survey division on this point as well."

As previously reported, the 7th International Joint Study is co-chaired by Hinokuni and the Hind Federation, with Brasilia so far involved only in an observer-like capacity. "If Window 6 comes to pass, Brasilia becomes a full observing participant," the division said. "The joint-study framework itself would widen by one more step." Together with the previously reported entrustment of Lineage 148's decoding to the Hind Federation, this autumn has seen several cases where the joint-study framework bore concrete fruit.

The division says it will hold off naming Window 6's provisional name until observation at the site is fully underway, even if the survey proceeds smoothly. "Windows 1 through 5 were all named for something that emerged only after observations accumulated," an official said. "Nobody yet knows what's waiting on the other side of the forest" — a remark that carried both anticipation and caution in equal measure.

A staffer who regularly gathers reader reaction for the survey beat said today's news was mostly met with a sense that "the world is getting bigger." One resident, who says they've lost the Window 1 viewing lottery more times than they can count, said, "Five windows were already more than enough strangeness for one lifetime, and now a sixth one might be beyond a forest somewhere — I can barely picture it. There's something nice, too, about this no longer being Hinokuni's privilege alone." The division says it will provide updates from the survey team as they come in.
