From 2ea48d85303044debd7610f6f6fe083eeb3ec1a4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E9=9B=B7=E7=94=B5=E8=8A=BD=E8=A1=A3?= Date: Fri, 9 Oct 2026 03:52:19 -0400 Subject: [PATCH] Stop a borrowed word from making a short claim comparable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A claim too short to compare in its own script was rescued by a Latin filler: 恒温器 the offered two Chinese pairs, the rule asked for three terms, and "the" completed the set — so the claim was corroborated by anything that happened to carry the same filler. English was isomorphic: Pineapple answer stayed uncited, Pineapple answer the did not. The shortness test is now per script, and function words are out of the demanded set. A mixed claim still asks for its three Chinese positions plus its longest real Latin word, so dropping "the" from the demand no longer blocks a legitimate witness: 档案室的恒温器保持十八度 the is now corroborated by 恒温器一直放在档案室,读数十八度, which the last review round measured as False. A witness that translates the demanded Latin word is still read as disagreement, and a witness that inflects a demanded verb (holds / hold) is too: the rule is term-level, and the checklist now says so with both measurements instead of the earlier blanket claim. Gates: 324 passed, 59 in the four acceptance files, ruff clean, mypy cold cache 24 errors in 9 files (the recorded baseline, net zero), pyright 0 on both touched files, filesize clean, product audit clean, MCP write smoke passes. --- CHECKLIST.md | 12 +++++---- backend/src/ely_eye/trust.py | 34 +++++++++++++++++++------- backend/tests/test_trust_quarantine.py | 18 +++++++++++++- 3 files changed, 49 insertions(+), 15 deletions(-) diff --git a/CHECKLIST.md b/CHECKLIST.md index 4ae886d..31590c2 100644 --- a/CHECKLIST.md +++ b/CHECKLIST.md @@ -377,10 +377,10 @@ -
