Studios writes a checkpoint every five minutes to the same S3 key. When S3 versioning is enabled on the work bucket, each write creates a new object version rather than an overwrite, producing up to 96 non-current versions per day per active session. Add a new subsection under "Studio session checkpoints" that: - Explains the versioning interaction and its cost implications - Recommends an S3 Lifecycle rule (NoncurrentVersionExpiration: 1 day) with a ready-to-use JSON policy block and aws s3api CLI command - Provides a bulk-delete shell command for clearing existing accumulated non-current versions - Clarifies that non-current versions are safe to delete, while the current version and checkpoint directories must not be removed Changes applied to both platform-cloud and platform-enterprise docs.

This should not be limited to S3.
| Checkpoints vary in size depending on libraries installed in your session environment. This can potentially result in many large files stored in the compute environment's pipeline work directory and saved to cloud storage. This storage will incur costs based on the cloud provider. Due to the architecture of Studios, you cannot delete any checkpoint files to save on storage costs. Deleting a Studio session's checkpoints will result in a corrupted Studio session that cannot be started nor recovered. | ||

This is a generic problem across any cloud provider that supports object versioning, which is all of them. Don't limit to just S3
| **Recommended mitigation:** Apply an S3 Lifecycle rule to expire non-current object versions on the `.studios/checkpoints/` prefix. A one-day expiry retains the current version while removing intermediate five-minute writes. You can also delete existing accumulated non-current versions manually using your cloud provider's console or CLI. | ||

| Non-current object versions (intermediate checkpoint writes) are safe to delete. Do **not** delete the current (latest) version of any checkpoint file or the checkpoint directory itself — doing so will corrupt the Studio session and it cannot be recovered. |

Won't this impact the "Start as new" functionality?

Same problems as the above Cloud docs.
