+## Development quality gate
+
+Compiler warnings are denied by project configuration. Before accepting any
+change, run the complete gate:
+
+```sh
+./scripts/quality-gate.sh
+```
+
+It requires clean `cargo fmt --check` output, runs Clippy across every target and
+feature with `-D warnings`, executes all tests, builds warning-free documentation,
+and produces the release binary. Any warning, formatting difference, test failure,
+or build failure stops the gate.
