📝 WalkthroughWalkthroughThis change adds native Bernini v2 support. It introduces shared guidance, media, preset, manifest, and sharded-checkpoint utilities. It implements Qwen multimodal processing, mRoPE handling, planner models, MaskGIT planning, and runtime loading. It adds Wan renderer nodes, dual-expert guidance, flow-UniPC sampling, node registration, and rotary-embedding dtype preservation. Unit tests cover the main planner, renderer, loading, scheduling, and utility paths. Merge Risk: 🟡 Moderate · up to The new Bernini v2 pipeline can reject valid seeds, consume excessive GPU memory on larger inputs, and mishandle several edge cases such as visual-item limits, single-character negative prompts, timestep precision, and malformed model metadata. These bounded correctness and runtime risks should be addressed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Validate the schema_version type before the cast.
int() accepts any numeric-looking value. If a manifest contains "schema_version": "v3" or null, int() raises ValueError: invalid literal for int() with base 10: 'v3' or TypeError. Neither message names the manifest path, so the user cannot tell which package is invalid. Every other check in this function reports a clear, path-aware error. Reject non-integer values with the same style.

Build the sigma schedule in float32, then cast.
set_timesteps is called at Line 372 with dtype=z.dtype, which is bfloat16 in the normal planner path. torch.linspace therefore rounds every sigma to 8 mantissa bits before the shift transform compresses the high end further. step then resolves the current index with torch.argmin((self.timesteps - timestep).abs()) at Line 297. If two neighbouring timesteps round to the same bfloat16 value, argmin returns the first index, and the step uses the wrong next_sigma - sigma delta. The schedule is a few hundred scalars, so computing it in float32 costs nothing and removes the collision.

Lines 454-455 are dead code; the mutation is discarded.
cond["inputs"][:, cond["output_mask"], :] uses boolean advanced indexing, which returns a copy rather than a view. target[:, indices, :] = current therefore writes into a temporary that is never read and never written back. The loop at Lines 456-459 already handles the cond branch correctly, because it performs the explicit write-back at Line 459.
Beyond the confusion, this copy is allocated on every planning step. With target_count near MAX_VIT_TARGET_TOKENS and a 7B hidden width, that is tens of MiB of wasted device allocation per step, for up to 50 steps.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Build the additive mask in the compute dtype to avoid a quadratic float32 allocation.
build_custom_attention_mask always materializes an [B,L,L] float32 tensor. create_plan in comfy/ldm/bernini_v2/planner.py (Line 274) moves this tensor to the load device and keeps it for all three branches for the whole planning loop. plan_forward in comfy/ldm/bernini_v2/qwen.py (Line 170) then allocates a fresh bf16 copy on every call, which is three calls per planning step for up to 50 steps.
The cost grows with L**2. MAX_VIT_TARGET_TOKENS is 4096, so a source video plus a video target puts L in the several-thousand range: at L = 8192 each float32 mask is 256 MiB, and three resident branches hold about 768 MiB of device memory before any activation.
Accept a dtype argument so the caller builds the mask once in the model compute dtype. This halves the resident footprint and removes the repeated per-call cast.

More than 64 visual items raises an opaque IndexError.
_visual_pattern indexes pads[visual_id] without a bounds check. max_visual_items defaults to 64, and split_reference_images in comfy/ldm/bernini_v2/planner.py (Line 120) expands each IMAGE batch into one entry per frame.

The len(negative_prompt) > 1 test silently ignores a one-character negative prompt.
A negative prompt of exactly one character (for example "1", or a single CJK glyph) fails this test. The uncond branch then falls back to the positive message text instead of the negative prompt, so negative guidance is silently lost for that input. Use an emptiness test instead of a length threshold.
