From 1e46f1c74424cbd562953cec6b5c01d21ee4601f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rene=CC=81=20Verheij?= Date: Wed, 4 Mar 2026 11:56:12 +0800 Subject: [PATCH 1/2] =?UTF-8?q?fix:=20break=20circular=20dependency=20Shap?= =?UTF-8?q?e=E2=86=92QueryParser=E2=86=92LinkedStorage=E2=86=92Shape?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a dispatch registry (`queryDispatch.ts`) as a leaf module that both Shape and LinkedStorage import without importing each other. Remove QueryParser (was a pass-through with no logic). LinkedStorage registers as the dispatch provider in `setDefaultStore()`.
