📝 WalkthroughWalkthroughThe pull request updates CUDA graph prefetch eligibility and removes custom polling price extraction across several API integrations. It adds BFL video upscaling, ByteDance Seedream, Seedance, and vCube capabilities, Fish Audio nodes, Gemini 3.7 Flash support, Meshy enhancements, and Wan 3 video nodes. It also updates node registrations, package versions, dependency pins, display names, model options, and a math test error match. Merge Risk: 🟡 Moderate · up to The backport adds and refactors several partner API node flows, but it still permits invalid speaker-tag input, can upload media without verified duration limits, can accept oversized combined Wan inputs, and may mishandle proxy polling for video upscaling. These issues can cause incorrect requests or rejected/failed jobs, so the PR needs fixes or explicit owner acceptance before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Inline comments:
In `@comfy_api_nodes/nodes_bfl.py`:
- Around line 1488-1500: Update the video validation flow surrounding
validate_video_duration so failure to read duration metadata raises an
actionable ValueError instead of allowing processing to continue. Ensure this
failure occurs before upload_video_to_comfyapi and preserves the existing 1–20
second validation for videos with readable duration.
- Around line 1159-1166: Remove the poll_via_proxy-specific flow from
_bfl_video_execute and inline the submit, poll, status-check, and download
sequence in FluxVideoUpscaleNode.execute. Keep proxy endpoint selection and
related behavior at FluxVideoUpscaleNode.execute, while preserving shared helper
behavior for other BFL video nodes.
In `@comfy_api_nodes/nodes_fishaudio.py`:
- Around line 53-66: Update _rewrite_voice_tags to reject any `@Voice` tag when
voice_count is less than two, raising a clear ValueError before rewriting;
retain the existing range validation and rewriting behavior for active
multi-speaker synthesis.
In `@comfy_api_nodes/nodes_wan.py`:
- Around line 1829-1838: Update the reference-video loop to read each duration
once and reuse that value for validation and total accumulation. Remove the bare
try/except around get_duration and ensure duration-read failures are not
silently treated as zero, preserving rejection through the existing
validate_video_duration flow and aggregate duration checks.

Learning: When reviewing ComfyUI nodes that use IO.DynamicCombo, account for schema expansion by comfy_api/latest/_io.py::DynamicCombo._expand_schema_for_dynamic. Prompt validation in execution.py validates each resulting IO.Combo value against extra_info["options"] and rejects invalid values with value_not_in_list before execute() runs. Review validation logic against only the reachable option domain for closed IO.Combo.Input lists inside a DynamicCombo, unless the node provides another input path that bypasses prompt validation.

Learning: In ComfyUI node implementations under `comfy_api_nodes/`, when building JSONata expressions that use `IO.PriceBadge` for `$lookup` against a price map keyed in lowercase, do not add an explicit `$lowercase()` around widget values (e.g., combo options like "1K", "2K", "4K"). The ComfyUI frontend automatically lowercases widget values before evaluating the JSONata expression, so the lookup keys will already match the lowercase map entries.

Learning: In Python partner API nodes under comfy_api_nodes/, keep each node’s execute body self-contained, including input validation and the submit → poll → status-check → download flow. Do not extract duplicated validation into shared helpers when limits are endpoint-specific or model-version-specific, because vendor constraints may diverge; preserve per-node readability, independent editability, and a limited blast radius.

Learning: When consuming dictionaries produced by IO.Autogrow.Type, rely on their iteration order to match the configured template-slot order. This ordering is preserved by _expand_schema_for_dynamic, parse_class_inputs, and build_nested_inputs, so consumers should iterate the dictionary directly when processing dynamic slots.

Learning: In the `comfy_api_nodes/` package, partner/API node `execute` implementations should keep the full submit → poll → status-check → download flow written inline within each node (even if similar logic appears across multiple nodes). This is an intentional repo convention to optimize per-node readability and independent editability, so during reviews you should generally not recommend refactoring this pattern into a shared helper function for these nodes (unless there’s a concrete correctness/security issue).

Learning: In `comfy_api_nodes` Python async node implementations (e.g., `async def execute`), synchronous CPU/IO-heavy helpers (such as video/audio trim/resize and base64/MP3 conversion) may be called directly without offloading to a thread executor (e.g., `asyncio.to_thread`). Treat this as an existing, broader refactor concern rather than a new PR regression: if the PR does not introduce additional synchronous blocking calls, reviewers should not flag it as a new issue. However, if the PR adds new synchronous CPU/IO work inside `async def execute`, prefer offloading with `asyncio.to_thread` (or an equivalent background executor) to avoid blocking the event loop.

Learning: When implementing ComfyUI API nodes in this repo, for any billable HTTP POST operations, follow the established policy: keep the existing default retry behavior. Do not add idempotency keys or disable retries. The rationale is to prevent failures from aborting the entire workflow; when reviewing new API nodes, check that POST billing requests preserve the default retry configuration and remain consistent with this policy.

If event-loop offloading is needed, implement it centrally in the shared helpers under comfy_api_nodes/util as a dedicated refactor, preserving clean call sites across partner nodes.

Keep proxy polling in FluxVideoUpscaleNode.execute.
poll_via_proxy adds one node-specific behavior to _bfl_video_execute. The new node also moves its submit → poll → status-check → download flow into a shared helper. Inline this flow for FluxVideoUpscaleNode and keep the proxy endpoint selection at that integration boundary.
Based on learnings, partner API node execute implementations keep the full submit → poll → status-check → download flow inline. As per coding guidelines, keep one-off behavior at the integration boundary.

Reject videos when duration metadata cannot be read.
validate_video_duration logs and returns when video.get_duration() fails. Line 1488 then bypasses the 1–20 second limit, and Line 1500 uploads the unverified video. Raise an actionable ValueError when duration lookup fails before upload.

Reject speaker tags when only one voice is active.
_rewrite_voice_tags runs for every model and voice count. With the s1 model, or with a single connected voice on s2.1-pro, @Voice1 is rewritten to <|speaker:0|> and sent as synthesis text. s1 and single-speaker requests do not use speaker tokens, so the token is silently synthesized or dropped instead of reporting the misuse. The completeness check on Line 267 only covers two or more voices, so this case has no guard.
Fail with a clear error when the text contains a speaker tag and multi-speaker synthesis is not active.
As per coding guidelines: "Let unsupported model formats, invalid quantization metadata, and bad states fail with clear errors instead of silently degrading output."
🐛 Proposed fix
- rewritten, referenced = _rewrite_voice_tags(text, len(voices))
- if len(voices) >= 2:
+ multi_speaker = model_name != "s1" and len(voices) >= 2
+ rewritten, referenced = _rewrite_voice_tags(text, len(voices) if multi_speaker else 0)
+ if multi_speaker:
missing = [i for i in range(1, len(voices) + 1) if i not in referenced]Also applies to: 266-278

Remove the bare try/except around get_duration().
validate_video_duration already handles a failed duration read: it logs the error and returns. The second call adds a bare except Exception: pass. When the read fails, the video contributes 0 seconds to total_video_seconds. The 15s aggregate check and the 30s combined check then pass for input that should be rejected, and the failure is silent.
Read the duration once and reuse the value.
🐛 Proposed fix
total_video_seconds = 0.0
for key in reference_videos:
validate_video_duration(reference_videos[key], max_duration=15)
- try:
- total_video_seconds += reference_videos[key].get_duration()
- except Exception:
- pass
+ total_video_seconds += reference_videos[key].get_duration()The coding guidelines state: "avoid unnecessary try/except blocks and use specific exceptions with useful fallbacks". The path instructions also require enforcement of "no unnecessary try/except blocks".
