From 8d43eac45a2647fd5857c727718163042c99f63d Mon Sep 17 00:00:00 2001 From: Shay Date: Wed, 27 May 2026 16:19:59 -0700 Subject: [PATCH] feat(matcher-extension/ME-1): currency-per-unit composition admission MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lights up the dormant consumption path from PR #398. Extends _match_rate_with_currency with a new branch keyed on anchor_kind="currency_per_unit_composition" — when a statement carries the " bought at $ each" shape with a same-sentence proper-noun subject, the matcher publishes: - composition_shape = "bound(count) × bound(unit_cost)" - composed_initial = CandidateInitial(entity=Subject, quantity=Quantity(count*amount, dollars)) The PR #398 consumption wire in inject_from_match consults composition_registry on composition_shape: an affirms entry admits the pre-composed CandidateInitial; falsifies suppresses; absence refuses. Subject binding under Option A (refuse when same-sentence subject absent). Option B (placeholder) forbidden by the brief; Option C (cross-sentence lookup) is ME-2. Truth-test scorecard (6-row binding table from PR #399): #1 Synthetic Maria admits ........ PASS #2 Case 0050 stays refused ....... PASS #3 train_sample 3/47, no regress . PASS (3 correct preserved) #4 wrong == 0 preserved .......... PASS #5 public 150/150 unchanged ...... PASS #6 All PR #398 tests still pass .. PASS (38 tests + new 21 = 59) Case 0019 stays refused (Option A) — admitting it requires cross-sentence subject lookup (ME-2 brief).
