Merge Risk: 🔵 Low · up to A missing hub can leave behind an agreement that authorizes access and incurs fees. The issue is localized, but the stale agreement should be cleaned up before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Saved agreements now control both cross-realm access and payments. Normal consent checks constrain access, but recovery can leave an agreement active after its hub disappears, potentially retaining authorization or charges. The identified exposure is limited to game guilds and installations; negotiation menus are deferred. Retained concerns

Guildloads agreements independently from hubs. Loading then removes missing hubs without removing their agreements. During a later installation transfer,onTransferredskips cleanup whenhub == null. The stale agreement can therefore authorise the hub throughhubPermittedand can be charged bygetPayableHubFees.Call
