…ision table The 103 rows left after §9-70.2 were attributed to candidate features with the §7 control (10 agents, measured where the feature can be emulated), and the two top designs were prototyped on a local branch and re-measured on all 626 rows: - helper propagation (F2): silent wrong answers 60 -> 44; - wide intermediates (WIDE): -3-though-the-answer-fits 52 -> 17, with measured risks outside the sample (a fast failure can become a hang, extracting a let changes the answer, MSVC has no checked int64 builtins, i64 itself overflows); - no mode changes a correct status-0 answer. STATUS ▶ entry (5) hands the choice to the user (§9-71.6, recommendation F2, Grok agrees); entry (4) moves byte-identical to start-block-052.md. The Delphi local gate passes with units that declare ML_ST_OVERFLOW. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… what clang accepts Grok verify: the reviewer's summary said 17,524, which its own four buckets contradict; re-running the same script (3 seeds x 200 x 80) gives 21,524 and 0 changes outside -3. clang 21 accepting __int128 was not in the evidence.
