From 1c61b117ae5675a345632ec7cc23a8edfae4c354 Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Tue, 12 May 2026 17:16:42 +0000 Subject: [PATCH] fix(canvas): case-insensitive extension lookup in getIcon + topology test fix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two pre-existing canvas test failures: 1. canvas/src/components/tabs/FilesTab/tree.ts:getIcon() FILE_ICONS keys are lowercase (".json") but the extension was looked up as-is (".JSON"). Result: FILE_ICONS[".JSON"] → undefined → fallback "📄" instead of "{}". Fix: lowercase the extension before FILE_ICONS lookup. Also added ?. null-coalescing on split().pop() to handle filenames without extension. 2. canvas/src/store/__tests__/canvas-topology-pure.test.ts sortParentsBeforeChildren test expectation was wrong: it assumed orphan would come after root, but when parentId references a missing node the orphan keeps its input order (orphan, then root). Updated the expectation and corrected the comment to match the actual behaviour. Closes #697.
