Bump nvidia-cudnn-frontend from 1.29.0 to 1.31.0 in the Bridge and final framework container overrides, and regenerate uv.lock with the updated Python 3.12 wheel hashes. Only cuDNN Frontend changes version; existing Transformer Engine, MCore, TileLang, and TVM FFI pins are preserved.

Companion release PR: #6431 (r0.7.0).

Validation:

  • uv lock --check passed in the CI container.
  • uv run pre-commit run --all-files passed in the CI container with the existing environment (UV_NO_SYNC=1).
  • uv run --no-sync python -m pytest tests/unit_tests/utils/test_gdn_utils.py -q -rA: 67 passed with Frontend 1.31.0 installed, including the installed Frontend FROST version-floor and parser checks.
  • git diff --check passed.

GPU kernels were not exercised locally because the host has an NVIDIA driver/library mismatch. L0/L1 CI is requested with needs-more-tests. No tests are quarantined.

Automatic Claude reviews have been retired. To request a pull-request review, post a comment containing:

/review

Add model=claude to use a Claude reviewer (the default is model=codex). mode=light|strict selects the review depth; for example, /review model=claude mode=strict. Comment /review help for all options.
