A registration under a stranger's name is said and skipped, not fatal

A module implementing a seat its credential does not (yet) claim registered tools under the seat's
name; the runtime treated them as the module's own, refused to serve another module's key, and the
whole runtime restarted in a loop — postgres on the control node, 2026-10-01, whose credential predated
the claims. Such a registration is now named in the log and left out; the module's own tools serve.
