Records the inference's max-over-paths semantics, the codegen gates (consume_count == 0, body-tail-not-binder, block-not-terminated, non-escape membership), the @-prefix elide on closure-pair globals, the rc_box_drop fixture's choice of a no-boxed-children ADT (shallow free sufficient), and the explicit scope cut for per-type drop fn (18c.4). Closes with the dispatch note for 18c.4 and the reminder that the new CLAUDE.md tidy-iter rule fires after 18f when the 18-arc closes.
