From d79b30a1a64b71628a763b031e0f72f899495430 Mon Sep 17 00:00:00 2001 From: claude Date: Tue, 4 Aug 2026 15:37:54 +0400 Subject: [PATCH] =?UTF-8?q?phraser:=20one=20count=20helper,=20so=20the=20w?= =?UTF-8?q?eather=20says=20"1=20=D0=B3=D1=80=D0=B0=D0=B4=D1=83=D1=81"=20(V?= =?UTF-8?q?-521)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The weather line spelled "градусов" out in the template, which is the wrong form for 1-4 and for every number ending in 1-4. Russian inflects the noun after a numeral, so the count splits into the number and {word}. hostWord in cmd/mavend/netscan.go already knew the rule for устройство and was the only place that did. It moves to internal/phraser as CountWord, with Degrees and Devices over it, and the three call sites that counted devices now read the same helper the weather line does. Degrees rounds before it counts, so the noun agrees with the number she is about to say rather than the reading behind it, and a negative reading counts by its magnitude.
