# Singularity R91 for ComfyUISingularity is a public-alpha ComfyUI custom node for Wan I2V / V2V cascade continuation.It is built for users who want longer Wan videos without manually extracting a last frame, loading it again, making another short clip, and stitching everything later.## What It DoesSingularity turns this manual loop:```textgenerate a short clipfind a good tail frameload that frame as the next sourcegenerate the next cliprepeatstitch everything later```into one controlled node workflow:```textgeneratepausechoose a tail framecontinue the same runsave one stitched final video```## Main Features- One visible ComfyUI node: <code>Singularity</code>.- Wan I2V / V2V cascade continuation.- Up to five cascade segments in this public alpha.- Optional pause after cascade 1, 2, 3, and 4.- Detached Source / Tail 1 / Tail 2 / Tail 3 / Result panel under the node.- Manual tail-frame selection before continuation.- Same-run resume instead of unrelated separate renders.- Final stitched video output.- Markdown report output with cascade, motion, runtime, delta, and Strategy diagnostics.- Clean public defaults: no bundled image, empty positive prompt, built-in Wan-style Chinese negative prompt.- Native ComfyUI image upload button is preserved.## New In R91R91 is a stabilization update for modern ComfyUI Desktop.- Visible title now shows <code>Singularity R91</code>.- The public node surface is clean for fresh installs.- The <code>math_control_mode</code> dropdown now shows only the clean public modes.- Older saved workflow values are still normalized by the backend.- Pause/continue UI remains detached below the node.- The native upload button is preserved.- Strategy Control Surface diagnostics are included in reports.- Experimental math remains neutral by default.## About The MathSingularity studies generation as an event:```textOutcome(t-1) + ObservedBehavior(t-1)= Strategy(t)= ObservedBehavior(t+1) + Outcome(t+1)```For normal users, this means the node helps you inspect whether the source image, prompt meaning, model behavior, sampler route, motion, and final video are staying connected.This is not a magic quality button. It is a control and diagnostics layer.Use <code>OBSERVE_ONLY</code> for a safe baseline.Use <code>STRATEGY_PRESSURE_WINDOW</code> only when you intentionally want to test bounded experimental math. With <code>high_delta_strength = 1.0</code> and <code>low_delta_strength = 1.0</code>, it stays neutral.Use <code>LATENT_DELTA_SCALE</code> and <code>DEEP_STEP_DELTA_CONTROL</code> only for research.## Recommended First Test```textcascade_count = 2pause_after_cascade_1 = trueframes_per_cascade = 49width = 704height = 1280fps = 16seed = 123math_control_mode = OBSERVE_ONLYhigh_delta_strength = 1.0low_delta_strength = 1.0save_video = truesave_report = true```Pick a source image, write a clear prompt, generate, choose a tail frame when the panel appears, continue, then inspect the final stitched video and report.## Public Alpha Notes- Models are not included.- This is Wan-first.- Heavy resolutions require more VRAM and time.- <code>CompletionGate = PASS</code> means the route completed and a final video exists. It does not guarantee perfect visual quality.- Always inspect the final video, not only the report.

# Singularity R91 Changelog## 0.1.1-r91 - Public StabilizationR91 is a public stabilization release for the current Singularity node.### Added / Updated- Public version promoted to <code>0.1.1-r91</code>.- Visible node title updated to <code>Singularity R91</code>.- Cleaner <code>math_control_mode</code> dropdown: - <code>OBSERVE_ONLY</code> - <code>LATENT_DELTA_SCALE</code> - <code>STRATEGY_PRESSURE_WINDOW</code> - <code>DEEP_STEP_DELTA_CONTROL</code>- Strategy Control Surface diagnostics are now part of the public report layer.- Reports can show how <code>STRATEGY_PRESSURE_WINDOW</code> compresses requested strength into a bounded effective strength.### Stabilized- Two-cascade pause/continue route.- Tail-frame selection panel.- Final stitched video output.- Native ComfyUI image upload button.- Source / Tail / Result panel behavior in modern ComfyUI Desktop.- Prompt purity: formula/topology text is not injected into the model-facing prompt.- Neutral math behavior: <code>high_delta_strength = 1.0</code> and <code>low_delta_strength = 1.0</code> do not mutate the latent delta route.### Public Defaults```textsource_image_file = nonepositive_prompt = emptynegative_prompt = built-in Wan-style Chinese negative promptcascade_count = 2pause_after_cascade_1 = trueframes_per_cascade = 49width = 704height = 1280fps = 16seed = 123math_control_mode = OBSERVE_ONLYhigh_delta_strength = 1.0low_delta_strength = 1.0image_crop = wan_nativesave_video = truesave_report = truesampler_trace_mode = OFF```### Validation- Python compile check passed.- Frontend JavaScript syntax check passed.- ComfyUI Manager JSON validation passed.- Installed Desktop node copy synced to R91.- Installed Documents node copy synced to R91.- Key source / installed file hashes match.- Pre-release ComfyUI Desktop smoke-test completed: - two cascades - pause / continue - final video saved - report saved - <code>EventCoreBodySummary = PASS</code> - neutral <code>STRATEGY_PRESSURE_WINDOW</code> output matched the neutral baseline visually <code>SSIM = 1.0</code>, <code>PSNR = infinite</code>)### ImportantExperimental math modes are still research tools. They can change motion, stability, and quality. Start with <code>OBSERVE_ONLY</code>, then change one variable at a time.
