Replaces the earlier "RC + inference, no annotations" position with a two-layer architecture: inference (intra-fn) + mandatory LLM-author mode annotations on fn signatures (inter-fn). Adds structured rationale for rejecting region inference (regions assume stack-shaped lifetimes; real programs need non-stack-shaped lifetimes for caches / memo tables) and linear types as primary mechanism. Schema additions enumerated for the 18-series: Type::Borrow / Type::Own (Iter 18a) Term::Clone (Iter 18c) Term::ReuseAs (Iter 18d) TypeDef.drop_iterative (Iter 18e) Migration plan extended from 18a-d (4 iters) to 18a-f (6 iters). JOURNAL records the regions excursion, the scope-shape reduction, and the LLM-author lever as the structural advantage Decision 10 cashes in on.
