• Refactor
  • Switched prefill and decode workers to round-robin load balancing for more predictable distribution.
• Chores
  • Removed creation of the expert distribution recording directory and related environment variable to streamline startup.

Walkthrough

The deployment YAML fixes the container command from python3E to python3 for prefill and decode. The launch script removes expert-distribution recording setup and switches worker flags to round-robin load balancing for prefill and a prefill round-robin balance flag for decode. No other arguments or control flow changes.

Changes

Cohort / File(s)	Summary
Deployment config command fix components/backends/sglang/deploy/disagg.yaml	Corrected container command interpreter from python3E to python3 for prefill and decode entries; no other config changes.
Launch script flag updates components/backends/sglang/launch/disagg_dp_attn.sh	Removed expert distribution recording dir/env setup; replaced --expert-distribution-recorder-mode stat with --load-balance-method round_robin (prefill) and --prefill-round-robin-balance (decode).

Poem

I twitch my ears at flags anew,
Round-robin hops, a balanced queue.
Python’s path now clear and bright,
No stray E to steal the night.
I thump, deploy, then swiftly go—
Prefill, decode, in perfect flow. 🐇✨

❌ Failed checks (1 warning, 1 inconclusive)

Check name	Status	Explanation	Resolution
Description Check	⚠️ Warning	The pull request description provides only a brief statement “Fixes 2 release bugs” and does not follow the repository’s required template. It lacks an Overview, Details on the changes, guidance on where reviewers should start, and any Related Issues section. Without these structured sections, reviewers do not have the context or specific pointers needed to evaluate the pull request effectively.	Please expand the description to match the repository template by adding an Overview that summarizes the purpose of the bug fixes, a Details section outlining the specific changes in each file, a “Where should the reviewer start?” section listing key files to review, and a Related Issues section that closes or references the appropriate issue numbers.
Title Check	❓ Inconclusive	The title “chore: typo and new commands” is too vague to clearly communicate the main changes in this pull request. It mentions a “typo” and “new commands” without specifying that it corrects the Python interpreter invocation in disagg.yaml or updates load balancing flags in the launch script. This lack of detail makes it hard for other team members to understand the primary purpose at a glance.	Please update the title to more specifically reflect the key changes, for example by referencing the corrected Python3E interpreter invocation and the adjustment of load-balancing flags in the disagg deployment and launch scripts; a concise yet descriptive title will help teammates quickly grasp the main purpose of the pull request.
