#### `--no-cas` flag for disabling CAS per command

The new `--no-cas` flag disables the CAS for a single invocation, even when the `cas` experiment is enabled. It is available on [`run`](/reference/cli/commands/run), [`stack generate`](/reference/cli/commands/stack/generate), and [`stack run`](/reference/cli/commands/stack/run).

```bash
terragrunt stack generate --experiment cas --no-cas
```

This is useful when you want to fall back to the standard getter path without unwinding experiment configuration.

Generation and runs error when `--no-cas` is combined with `update_source_with_cas = true` on any reachable `unit`, `stack`, or `terraform` block, since relative sources in catalog repositories cannot be resolved without the CAS.
