# Singularity for ComfyUI

https://github.com/DIIIUA/ComfyUI-Event-Equality-Core/

Singularity is a public-alpha ComfyUI custom node for Wan I2V / V2V cascade continuation.

Its main feature is the Tail 5 Continuation Gate: the workflow can pause between cascade segments, show the source image plus five tail-frame candidates, let you choose the best continuation frame, then continue the same run and save one final stitched video.

In simple terms:

```text

Generate a segment.

Pause.

Pick the best tail frame.

Continue the same run.

Get one stitched final video and a report.

```

## Why This Matters

Long Wan extension workflows usually require a lot of manual work:

- generate a short clip;

- find a good last frame;

- reload that frame as a new source;

- run another clip;

- stitch separate outputs later;

- guess where the continuity broke.

Singularity moves that loop into one node.

You still make the creative decision, but the node gives you the pause point, frame candidates, continue button, final stitch, and diagnostics.

## Key Features

- One visible ComfyUI node: Singularity.

- Wan I2V cascade generation.

- Up to five cascade segments in the current public alpha.

- Optional pause after cascade 1, 2, 3, and 4.

- Tail 5 Continuation Gate:

- Source

- Tail 1

- Tail 2

- Tail 3

- Tail 4

- Tail 5

- Result

- Manual tail-frame selection with a green outline.

- Same-run continuation after selecting a frame.

- One final stitched video.

- Markdown runtime report.

- Public-safe default: Observe Only, neutral deltas, reports on, trace off.

## Named Function Layers

Tail 5 Continuation Gate

The frame-choice layer. You choose which tail frame should become the next segment source.

Same-Run Cascade Stitch

The final-output layer. The node saves one stitched video instead of leaving you with separate segment clips.

Observer Math Baseline

The safe default. It records what happened without intentionally changing generation tensors.

Prompt-Pure Strategy Map

Prompt analysis stays report-side. The public default does not inject formula text into the model-facing prompt.

Completion Report Gate

The report tells you whether the route completed. CompletionGate = PASS means a final video exists; it is not a visual-quality guarantee.

Seam And Drift Diagnostics

The report can show cascade seam jumps, motion spikes, tail/source continuity pressure, and other clues about where the continuation changed.

## R178 Update

Version:

```text

0.1.1-r178

Singularity R178

Tail 5 Continuation Gate

```

R178 updates the public surface:

- cleaner visible mode names;

- grouped UI sections;

- hidden internal transport controls;

- native ComfyUI image upload preserved;

- Tail 5 panel stabilized for pause/continue;

- clean public baseline with no active generation-math mutation;

- improved report evidence for continuation, seam, and public-readiness checks.

## Public Defaults

```text

cascade_count = 2

pause_after_cascade_1 = true

frames_per_cascade = 49

width = 704

height = 1280

fps = 16

seed = 123

math_control_mode = Observe Only

high_delta_strength = 1.0

low_delta_strength = 1.0

strategy_field_mode = OFF

sampler_trace_mode = OFF

prompt_transcode_mode = Report Only

save_video = true

save_report = true

```

If the default resolution is too heavy, lower it before rendering. A small test size such as 416 x 608 is useful for fast comparisons.

## Important Notes

- This is a public alpha.

- The node is Wan-first.

- Models are not included.

- Current public cascade limit is 5.

- Heavy resolutions require more VRAM and time.

- Always inspect the final MP4.

- CompletionGate = PASS means the route completed, not that the video is artistically perfect.

- Research modes are available, but they can change or break the output.

## Recommended First Test

```text

cascade_count = 2

pause_after_cascade_1 = true

frames_per_cascade = 49

fps = 16

seed = 123

math_control_mode = Observe Only

sampler_trace_mode = OFF

prompt_transcode_mode = Report Only

save_video = true

save_report = true

```

Run the workflow, choose the best tail frame at the pause, continue, then review the final stitched video and report.
