From 324db573739e4ce20366c3d75c7cf2051533f506 Mon Sep 17 00:00:00 2001 From: Shay Date: Sat, 18 Jul 2026 13:07:40 -0700 Subject: [PATCH] feat(adr-0249): P5 arithmetic-chain lift domain on real GSM8K holdout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the turn-program executor into the generalized-lift instrument and measures it against the REAL GSM8K dev holdout (evals/gsm8k_math/dev, never the templated cases), using each problem's ground_truth_graph. Baseline is a symbolic fold of the SAME compiled turn program: both paths consume identical problems, the corridor relaxes each step, the baseline folds it numerically. Honest result on the sealed 50-case dev holdout: 26 problems are Tier-1 affine single-accumulator ingestible and solved wrong=0; the corridor matches the symbolic fold on every one (PARITY, delta=0) — the field matches arithmetic, it does not beat it, so this is real-holdout coverage, NOT a manufactured lift. The 24 refused (all not_single_accumulator / multi-entity) are the recorded Tier-2 frontier, never silently dropped. Corrects the now-stale scope-limitation note ('no reader-to-Hamiltonian compiler exists…') — the compiler exists as of this arc; the note now records real-data Tier-1 coverage and the multi-entity frontier. wrong_zero_guard_held extended to bind both exact-regime domains (deductive flagship + arithmetic). 10/10 pins (5 new + 5 existing instrument tests still green).
