+# Type check
+npm run type-check 2>&1
+
+# Check for any `any` types (should be zero)
+grep -rn ': any' src/ --include='*.ts' --include='*.vue' | grep -v node_modules | grep -v '.d.ts'
+
+# Check for inline Tailwind violations (long class strings)
+grep -rn 'class="[^"]\{100,\}"' src/ --include='*.vue'
+
+# Check for TODO/FIXME
+grep -rn 'TODO\|FIXME' src/ --include='*.ts' --include='*.vue'
+
+# Check for console.log (should be cleaned before production)
+grep -rn 'console\.\(log\|warn\|error\)' src/ --include='*.ts' --include='*.vue' | wc -l

+```bash
+sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.228 \
+  'source ~/.cargo/env && cd ~/archy/core && cargo clippy --all-targets --all-features 2>&1 && cargo fmt --all -- --check 2>&1'
