+CI pins Node 24. On this VM, `node` on `PATH` can resolve to an older binary under `/exec-daemon` ahead of nvm. Select Node 24 in the same shell before `npm` or `cdk`:
+
+```bash
+export NVM_DIR="$HOME/.nvm"
+. "$NVM_DIR/nvm.sh"
+nvm use 24
+export PATH="$(dirname "$(nvm which 24)"):$PATH"
+```

+Canonical checks: `npm ci`, `npm run build`, `npx cdk synth`. Also run `cdk diff` for every stack this change touches and review the output before opening the PR. Do not `cdk deploy` from this environment.
