+# deploy/windows/installer/bundle/ is BUILD OUTPUT: build-installer.sh stages a
+# complete copy of the application there, plugins included. Without this,
+# collection walked into it and imported every plugin a second time under a
+# second path, so SQLAlchemy raised "Table 'printeditems' is already defined for
+# this MetaData instance" and the whole suite failed to collect - on a tree with
+# nothing wrong in it, purely because somebody had built an installer first.
+#
+# It only started biting when the bundle grew from four plugins to thirteen,
+# which is the sort of delay that makes this look like a code fault rather than
+# a stale artefact.
