Records what shipped in 18c.2 (activation gate, two diagnostic codes, position model, the new parse_term / term_to_form_a round-trip in ailang-surface, gate on clean-typecheck), the three known false negatives that are deliberate scope cuts (missing-consume-of-Own, lam captures conservative, pattern bindings start fresh), and the dispatch for 18c.3 (uniqueness inference + codegen inc/dec — the iter where RC actually starts collecting memory).
