📝 WalkthroughWalkthroughPixVerse now supports V6 models through shared input, validation, pricing, upload, error, status, and generation helpers. Five nodes provide text-to-video, image-to-video, first-last-frame transitions, video extension, and reference fusion. The nodes support native audio, styles, multi-clip generation, reference validation, and Omni mode. Existing nodes use normalized status handling and ComfyAPI media uploads. The extension registers all five V6 nodes. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)

In `@comfy_api_nodes/nodes_pixverse.py`:
- Line 718: Rename the new Pixverse node_id values from the PixverseV2* prefix
to PixverseV6* so they match the V6 display names, descriptions, and request
models; apply this consistently to all affected node definitions, including
PixverseV6TextToVideoNode and the corresponding IDs at the other noted
locations.
- Around line 693-700: Remove the explicit max_retries=0 override from the
sync_op call in _pixverse_generate so the billable generation POST uses the
repository’s default retry behavior; leave the endpoint and request handling
unchanged.

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.

Timestamp: 2026-07-16T16:29:35.022Z
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.

Timestamp: 2026-08-11T17:33:31.657Z
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.

Timestamp: 2026-05-07T17:59:26.050Z
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: 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.

Timestamp: 2026-07-14T20:09:03.091Z
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).

validate_video_dimensions so unavailable or unreadable dimension metadata raises
a clear ValueError before upload_video_to_pixverse is reached. Ensure dimension
verification failures cannot bypass the V6_MAX_SOURCE_VIDEO_SIDE limits, while
preserving the existing duration validation and valid-dimension behavior.
