+"""P1-4 regression: webhook server must isolate connections per ``db_path``.
+
+The previous implementation cached a single module-level
+``_DB_CONN`` and reused it across ``make_server`` calls regardless of
+the path argument.  That let two webhook server instances point at the
+same database while each thought it was talking to a different one.
+The fix keeps a per-path connection cache; this test locks the
+behaviour so future regressions collapse immediately.
