The issue tracker's history lasts seven days on the events stream and its bucket fills toward a cap with no warning (issues 501, 502). A module may now declare `logs`; the controller creates each as a stream on the bus (create-or-update, never deleted or recreated, reported when undeclared), issues it to the owner's assignments in their membership, grants the runtime exactly the append and direct-read subjects, and raises a condition when any module's bucket or log reaches 75% of its cap, cleared below 70%.
