Reproducibility and claim boundaries
Evidence, not a tutorial-shaped guess.
This page records what was downloaded, how every frame was retained and audited, how the capture mechanism was investigated, what was executed in Blender, which claims were corrected, and what remains unknown.
Source acquisition
Exact public media, hashed before interpretation.
1280×720 · H.264 High · 15 fps
295.466667 s · no audio
4,432 decoded frames
720×720 · H.264 High · variable timing
3.96 s · no audio
119 decoded frames
The formats were explicitly selected with yt-dlp. FFmpeg extraction used passthrough timing: no `-r`, fps filter, interpolation, decimation, `mpdecimate`, or scene-selection filter. Per-frame FFprobe PTS is authoritative, especially for the variable-timing companion.
Capture forensics
The clip is timed screenshots, not an input recording.
Main frame F4431 visibly shows “ChronoLapse by Keeyai” with Time Between Captures set to 1. At the public Chronolapse repository’s inspected commit, its screenshot routine copies a desktop bitmap with `wx.ScreenDC` and `MemoryDC.Blit`; it does not query or explicitly draw the operating-system cursor.

exact Chronolapse binary/commit used
Application-drawn overlays are different evidence: when Blender’s brush or resize circle appears, the ledger records every recoverable sampled frame with its screen-space center and radius. An inferred operation is never relabelled as a recorded click.
Original-resolution sequential audit
Every decoded frame is represented in the UI ledger.
Each range auditor inspected every assigned original PNG sequentially at 1280×720 for the main recording and 720×720 for the companion. Contact sheets and OCR navigated the corpus but did not substitute for native-frame inspection. The final strict compiler rejected missing or overlapping frames, invalid PTS, unmeasured visible cursors, and visible brush samples without radii.

Measured review throughput
Automation found attention targets; people still verified the pixels.
The navigation pass used FFprobe timestamps, exact PNG hashes, OpenCV luma and edge deltas, 320-pixel SSIM, perceptual hashes, contact sheets, and crop-specific OCR. None of those outputs counted as visual confirmation. The acceptance receipts were created only after an auditor opened every cited native PNG at original detail and compared its UI state with adjacent frames.

Caught claim errors
Full resolution changed the report.
- The glass mask dialog at F3333 is 128×128. The nearby 1024 belongs to the separate V.G. bake panel. Every reconstruction artifact was rebuilt after this correction.
- The compositor node at F4010 is named Pixelate, not Dilate.
- F4007–F4015 is the Compositor, not the Shader Editor. Exact hourglass execution remains unobserved; later creator replies confirm this reusable group provides final hard pixelization/antialias removal across models.
- F4214–F4267 remaps the falling stream’s UVs onto the sand image; it does not paint a vertical stream highlight.
- The sand dialog starts 128×128 Linear at F3595; image data later reads 64×64 at F3650. The transition itself is unknown.
Tool execution
The exact Blender and Ucupaint pair was executed in isolation.
Blender 5.1.0 and Ucupaint 2.4.5 are directly visible in the recording. Both official archives were hashed; the add-on was installed into an isolated Blender user environment rather than the global profile.

Primary process replay receipt
Twenty-five real `.blend` checkpoints, not a screenshot slideshow.
The replay rebuilds the visible process from default cube through final parenting. Every checkpoint embeds its source-frame range, evidence class, and replay operation. It is an evidence-linked reconstruction—not SquareAnon’s original file, topology, or hidden brush event log.

| Variant | Changed pixels vs final | Mean absolute RGB delta | Interpretation |
|---|---|---|---|
| Emission / unlit | 0.00% | 0.0000 | Reconstruction identity: unlit emission is this reconstruction’s final branch. |
| Linear filtering | 11.38% | 0.2023 | Localized but visible softening of nearest-filtered bands. |
| Opaque glass / no mask | 13.67% | 10.2435 | Sand visibility and glass storytelling collapse. |
| No vertex color | 34.41% | 2.0201 | Broad but relatively subtle value contribution. |
| Neutral textures | 35.35% | 18.3334 | Largest loss of authored material/form information. |
| Runtime Lambert | 35.02% | 12.8196 | Live light reshades the already painted surface. |
| Rotated runtime key | 35.02% | 17.6197 | Asset separation nearly disappears under the moved key. |
The reconstruction’s greyscale and two-value aids are diagnostic, not automated beauty passes. The two-value aid reveals a real weakness: much of our dark wood merges with the black background. The guide keeps that failure visible.
