Greptile Overview

Greptile Summary

This PR updates the executor documentation to remove maturity labels and reorganize content, promoting RayActorPoolExecutor to a more prominent position. The changes improve the overall presentation by:

• Removing "Production Ready" and "Experimental" labels from the architecture diagram in release notes
• Reorganizing the execution backends guide to present RayActorPoolExecutor before RayDataExecutor
• Streamlining descriptions to focus on use cases rather than maturity status
• Removing the comparison table that highlighted experimental status

However, the documentation has an inconsistency: while the changes suggest RayActorPoolExecutor is being promoted from experimental status, the module still lives in nemo_curator.backends.experimental.ray_actor_pool throughout the codebase. Additionally, unlike the other executors, RayActorPoolExecutor lacks an import code example, which could confuse users about the correct import path.

Confidence Score: 3/5

• Documentation-only changes with potential usability issues but no runtime impact
• The changes are safe from a technical perspective (documentation only, no code changes), but the missing import example for RayActorPoolExecutor and the disconnect between the documentation's presentation (suggesting stable/promoted status) and the actual code structure (still in experimental namespace) create user confusion and inconsistency concerns that should be addressed before merge
• docs/reference/infrastructure/execution-backends.md requires attention to add the missing import example and clarify the experimental status of RayActorPoolExecutor

missing import example for RayActorPoolExecutor

Unlike XennaExecutor and RayDataExecutor, there's no code example showing how to import RayActorPoolExecutor. Based on the codebase, the correct import is:

from nemo_curator.backends.experimental.ray_actor_pool import RayActorPoolExecutor

Consider adding an import example here for consistency and to help users.
