+# Smoke CI Gate - TEMPORARILY DISABLED
+#
+# Disabled at maintainer request. The gate currently fails for EVERY pull
+# request regardless of its contents: the pinned dependency set (e.g.
+# trie-db 0.28.0) no longer compiles under the stable rustc that CI
+# installs fresh on each run (1.98.0), so `cargo clippy --all-targets
+# --all-features` aborts before ever reaching project code, and the
+# workspace test step hits the same failure.
+#
+# Re-enable once the dependency/toolchain baseline is refreshed.
