Serge review automation is now reachable behind the VPN, and a critical xet file download issue tied to redacted hashes in gated repos is resolved.

Transformers shipped a VPN relay workflow [1] that re-signs and re-delivers webhook events to Serge's internal endpoint, making AI-assisted code review functional for the first time. The same PR established .ai/review-rules.md to orient the model toward repo conventions. In parallel, the CI harness unified all GitHub API calls into a single function [2] with pre-flight token validation and per-request rate-limit logging, eliminating silent failures from expired credentials. Transformers-ci split its slowest-tests and failing-tests panels by CPU vs GPU [4], after GPU jobs dominated the raw leaderboard and pushed actionable CPU tests off-screen; the same series added run_id to failure traces [3] so the dashboard can now answer "has this test failed in the last N runs of its job?" The huggingface_hub team fixed a critical xet download failure [6] where tree-cache queries returned redacted hashes (64 asterisks) on gated repos, causing hex parsing to fail; the fix validates cache entries on read and write. TRL unblocked bitsandbytes 0.50.0 support [5] by fixing quantization tests and reverting a temporary version pin, while also correcting a latent dtype-comparison bug.

Action items

→ If you maintain xet file downloads on gated repos, upgrade huggingface_hub immediately huggingface/huggingface_hub [immediate]
→ Update TRL and accept bitsandbytes 0.50.0 in your dependency chain huggingface/trl [plan]
→ Monitor transformers-ci dashboard panels for reduced noise on CPU test visibility huggingface/transformers-ci [monitor]
