Cross-region party world routing

On October 8, 2026, shared-world joins falling through the solo allocation path used the member’s saved region, even when they had accepted a party invitation from a leader in another region. Party hunt allocation already used the leader.

CITY and SHARED fallback allocations now use the current party leader’s region. The selected region is retained for capacity retries. Tutorial allocations keep the player’s preference, and leaving the party restores personal world routing without changing the stored preference.

Validation: 39 controller tests and 26 HTTP party tests passed. HTTP expectations were updated for the previously deployed 1000 ms candidate polling field; the old expectations also failed against the unmodified production controller.

The compiled controller was deployed to the central metagame only. Regional workers receive its routing decision. This does not establish that every reported disconnect is resolved or that separate regional infrastructure outages are fixed.
