Bot review (bedrock-claude-opus-5) — DM the bot to share feedback.

Docs-only change: reorganizes the 0.46 CHANGELOG entries into *Quantization* / *Speculative Decoding* / *Megatron Framework* / *Misc* subgroups (matching the existing 0.45 style), folds the top-level Experimental section into 0.46 Misc as an (Experimental) bullet, and opens a 0.47 placeholder section.

I fetched the full file at the PR branch and verified nothing was dropped in the shuffle — every removed bullet (D-PACE, streaming spec-dec, Domino, CP/DP, Minitron variants + sub-bullets, VLM prune/PTQ/distill, day0-release, --target_dla, prepare_megatron_data_blend, puzzletron) reappears exactly once, and no duplicates were introduced. The mis-nested "Nested submodel reverse mappings…" paragraph is correctly promoted from an indented continuation of the ONNX FP16/BF16 bullet to its own Bug Fixes bullet. RST structure (heading underline length, bullet indentation for sub-lists) is valid.

Two entries are net-new rather than moved (grouped-GEMM TEGroupedMLP Minitron pruning with --no_moe_grouped_gemm, and distill.py --checkpoint_keep_last -1 / export_distilled_megatron_to_hf.py --export_iterations); I confirmed both features exist in the repo (examples/megatron_bridge/prune_minitron.py, examples/megatron_bridge/README.md + tests), so these look like previously-missing changelog entries being backfilled — fine, just slightly beyond "refactor".

Minor, non-blocking: the new 0.47 section is four bold headers with no content yet, and 0.46 is still dated 2026-08-xx (unreleased) — if 0.46 hasn't shipped, the 0.47 stub may be premature. No licensing files touched, no tests needed for a changelog-only change.

In `@CHANGELOG.rst`:
- Around line 79-80: Move the VILA/NVILA support removal and minimum NeMo
container requirement entries from the `**Deprecations**` section into
`**Backward Breaking Changes**` in `CHANGELOG.rst`, preserving their existing
text and order. Keep `**Deprecations**` limited to changes that remain
functional during migration.
- Line 71: Update the recommendation in the changelog entry to direct users to
the canonical examples/hf_ptq path instead of the compatibility examples/llm_ptq
symlink, while preserving the existing AutoDeploy guidance.
