From 6e51f2c5bb366b6daa81c3e6cb3a8a47dff5cbec Mon Sep 17 00:00:00 2001 From: Florent Tapponnier <160007691+Flotapponnier@users.noreply.github.com> Date: Tue, 8 Sep 2026 11:34:30 +0200 Subject: [PATCH] fix(243): scope headline and report to the Singapore probe, drop the Asia-Pacific claim Same rescoping as the main hotfix, applied to the two-region dev version: the headline still cites Singapore, the region tabs stay, every chain-wide superlative and the unsourced Asia-Pacific justification are gone.
