Records the drop-symbol scheme (uniform @drop_<m>_<T> for every ADT, even no-boxed-children ones; pair+env drop fns for escaping closures), field_drop_call's per-type dispatch and the three fall-back cases (Str / Fn / Type::Var), the unchanged Term::Let emission gates, and the explicit deferral of stack-recursion to 18e's worklist allocator. Also lists the four known-debt items (stack-recursive drop, closure-typed ADT fields, Type::Var fields, fn parameters) so 18d's design surface is clear.
