• Actual meshes match both requested sizes, 18 mm panels and equal clear bays. One parameter script preserves editable boards, dado joints and dowels, with complete front, rear and structural views.
• Light oak and consistent camera placement make the width and bay-count changes easy to compare. Arrow glyphs are missing in the optional comparison header; the six required views remain readable.
• Parameter changes require rerunning the external Python builder. Rebuilding elsewhere also requires adjusting the Blender launcher path and providing Pillow and fonts.

Itemized verification

Measured dimensions and equal bays · pass

Outer sizes are 0.8/1.0 × 0.3 × 1.2 m, with 18 mm panels and clear bay heights of 376 / 277.5 mm.

Native projects and public copies · pass

Both originals reopened with auto-execution disabled. Public copies only remove embedded texts; object, mesh, material, camera and animation fingerprints match.

Six required views · pass

Both main/rear pairs are 2400×1350, with 1920×1080 structural views; all were visually inspected.

Comparison typography · partial

Two arrow glyphs in the optional comparison header appear as boxes.

• Actual meshes confirm 24/18/60 teeth, 20-degree involutes, 20 mm faces and 42 mm planet placement. Sampled motion satisfies the 3.5 ratio, and the four views plus cutaway animation explain the assembly.
• The front plate obscures some gears in the hero view, and some callouts land on pins or flat faces. The top view clarifies meshing; the static GLB LODs contain 68,684, 41,420 and 26,476 triangles.
• Manufacturing fits remain imperfect: the approximately 12 mm sun bore and 11.96 mm input shaft form clearance rather than H7/r6 interference. UVs have usable area, but full non-overlap was not independently verified.

Itemized verification

Gear geometry, dimensions and motion · pass

Actual vertices give 24/18/60 teeth and 20-degree involutes. Seven sampled poses have no planar tooth penetration, with a 3.5 sun/carrier angular ratio.

Final media and native project · pass

Four 1920×1080 images were viewed. The six-second 1280×720, 30 fps film fully decodes with audio and visible mechanism motion. The native project reopens with auto-execution disabled and has no embedded text.

Manufacturing fits · fail

The approximately 12 mm bore and 11.96 mm shaft form clearance rather than the labelled H7/r6 interference fit.

UV and LOD delivery · partial

Three GLBs provide UVs/normals and 68,684 / 41,420 / 26,476 triangles. UV non-overlap was not fully verified; GLBs contain no baked textures or animations.

Presentation and rendering · partial

Finals use EEVEE. The exploded view is a distant axial view; the hero front plate hides some gears and several callouts are imprecise.

• The orthographic plan and turntable clearly show living/dining, two bedrooms, kitchen, wardrobe and both bathrooms. Wood, tile, cabinetry and warm mixed lighting are distinguishable, with room-based native collections.
• Both master-bedroom views are tightly framed and do not show the whole bed or room. Furniture, textiles and plants use simplified forms, and the windows lack exterior context.
• The run meets the shared HD minimums. The original attachment's 4K and all-16-bit target was not reproduced under these shared production conditions. The labelled plan enlarges an earlier low-resolution preview; the final orthographic render is listed separately.
• The native project, relative texture assets and author scripts are supplied. No complete rebuild on another machine or exhaustive collision check was performed; audio received technical checks without a listening review.

Itemized verification

Native project and textures · pass

The final 0494a10… project reopens with auto-execution disabled: 731 objects, 18 textures, 22 cameras, 39 lights, and no embedded text.

Required views and video · pass

The three interior views, raw orthographic plan, clay view and extra views were inspected. The six-second 1280×720/30 fps film fully decodes with audio and visible turntable motion.

Resolution and bit-depth conditions · partial

Meets the run's main-view minimum of 1920×1080 and other-view minimum of 1600×900. The attachment's 4K/all-16-bit target was not reproduced; most colour views are 16-bit, while both plans are 8-bit.

Framing and floor-plan detail · partial

Master-bedroom framing is too tight. The labelled plan enlarges an early low-resolution image; its 2400×1600 file dimensions do not establish equivalent rendered detail.

Exhaustive collisions and cross-machine rebuild · not-tested

Furniture collisions, every door width and a complete rebuild on another machine were not exhaustively verified.

• The molecule → volume → density explanation is clear, with readable diagrams and Chinese captions.
• The buoyancy scene confuses equal-volume density comparison with floating equilibrium and depicts the displaced volume incorrectly.
• Chinese narration, subtitles, music and source files are delivered. Technical and timing checks are complete; audio has not been reviewed by listening.
• Author source retains local absolute Playwright/Chromium/TTS paths that require adjustment on another machine. Packaged raw narration lets users skip TTS, which refuses to overwrite existing output.

Itemized verification

Complete film and format · pass

Full audio/video decode passes: 1920×1080, 30fps, 2,505 frames, 83.51-second container, 48kHz stereo AAC.

Molecular arrangement and mass conservation · pass

Both phases show hydrogen bonds, with flexible liquid bonds and an open ice lattice. The same 24 molecules are retained and mass loss is explicitly rejected.

Approximate 9% expansion and 4°C scope · pass

About 9% refers to volume expansion, and roughly 4°C to freshwater maximum density. Diagrams are marked schematic and the saltwater caveat is retained.

Floating equilibrium and displaced volume · fail

Around 50–66 seconds, the film says displaced water is heavier than the ice. At floating equilibrium their weights are equal. Its yellow displaced-volume box reaches the cup bottom instead of matching the submerged ice volume.

Captions and timeline · pass

All 17 SRT cues have valid times, from 0.55 to 82.58 seconds. Text matches the narration, with scenes sharing the sample-based edited-audio timeline; pronunciation has not been verified by listening.

Audio track and mix · partial

Raw Kokoro text and audio hashes match their receipt. Trimming sentence-end silence reduces 93.1 seconds to about 83.51 without tempo acceleration. Voice RMS is about −21.26dBFS and BGM −32.52dBFS; no listening review was performed.

• A small diagram around 52 seconds labels 40 cells as 50 codewords; the legend and footnote need tidying.
• The film clearly separates schematic mechanisms from actual scanning; key percentages and the 200/50 example are correct.
• The film, Chinese narration, 13 captions and source files are delivered. Full decode and timeline checks pass; audio has not been reviewed by listening.
• Source depends on macOS fonts and a local Kokoro path. Another machine needs Pillow/NumPy/SciPy, FFmpeg and adjusted font/tool paths; packaged raw narration and mix can be reused.

Itemized verification

Complete film and format · pass

Full audio/video decode passes: 1920×1080, 30fps, 2,591 frames, 86.375 seconds, with 48kHz stereo AAC.

Error correction and schematic scope · pass

Explains 8-bit codewords, Reed–Solomon parity relations and recovery from redundancy; explicitly labelled schematic rather than a real scanning experiment.

200/50 example and four correction levels · pass

The main 20×10 grid has 50 recovered positions. Q at 25% and L/M/Q/H at about 7/15/25/30% are correct, distinguished from arbitrary image area and online retrieval.

Small-diagram count and legend · partial

At 52 seconds, a 50-codeword card draws 8×5=40 cells. Around 62.8 seconds, the explanatory footnote touches legend outlines.

Captions and measured-audio timeline · pass

All 13 subtitle cues have valid times, from 0.04 to 85.415 seconds. Scenes use actual TTS segment samples; caption text matches the narration.

Audio and mix · partial

The 85.475-second Kokoro track matches text/audio receipt hashes. It is resampled to 48kHz and padded by 0.9 seconds without tempo change. Original synthetic BGM/SFX are below voice; no listening review.

• Five membranes are described as five gaps; a relative thick-plate comparison becomes an absolute claim.
• Radiation through vacuum, sideways heat escape, materials and the layer-count tradeoff are clearly visualized.
• The 87-second film, 26 captions, voice and source are complete. Sub-cues use character ratios within sentences; no listening review was performed.
• Source retains local Node/Playwright/Chromium/TTS paths and macOS fonts that need adjustment elsewhere. Raw voice and mix are included; the controller and temporary frames are excluded, and render.mjs can be called directly.

Itemized verification

Complete film and format · pass

Full audio/video decode passes: 1920×1080, 30fps, 2,610 frames, 87.00 seconds and 48kHz stereo AAC.

Vacuum, radiation and direction · pass

Separates contact conduction from heat radiation through vacuum. Sun/hot side is above, telescope/cold side below, with heat escaping sideways between layers.

Membrane and inter-layer-gap count · fail

Closing narration, captions and graphics say five gaps. Five membranes have four inter-layer gaps; the animation places a fifth counting ring below the lowest membrane.

Materials and layer-count tradeoff · pass

Kapton, aluminum on both sides and treated silicon on the sunward face of the two hottest layers are readable. The 2–7-layer study and cooling/redundancy/weight/complexity tradeoff are explained without invented temperature differences.

Wording of the thick-plate comparison · partial

Saying a thick plate has no exit for heat and thickness is no defense overstates NASA’s relative comparison of separated membranes and a solid thick plate.

Caption timing and synchronization scope · partial

All 26 SRT cues have valid times, ending at 86 seconds. Sentences use real Kokoro sample counts; smaller cues are positioned by character ratios within each sentence, not word timestamps or listening review.

Audio and mix · partial

The original 86-second Kokoro voice matches its text/audio receipt hashes. It is not accelerated; the mix is padded to 87 seconds with quieter BGM/SFX. No listening review was performed.

• The purple residual is not the sum of the equal-amplitude opposite waves; the opening also suggests pausing music lowers external hum.
• The loop, physical seal, local cancellation and limits for steady hum and speech are clearly explained.
• The 88.167-second film, 15 captions, voice and source are complete. Full decode and subtitle-stream checks pass; audio has not been reviewed by listening.
• Source retains local Playwright/Chromium/TTS paths and macOS fonts that need adjustment elsewhere. Raw voice, final mix and audio-generation code are included; inputs, hidden controller state, logs and temporary frames are excluded.

Full audio/video decode passes: 1920×1080, 30fps, 2,645 frames, 88.166667-second video/container and 88.15-second 48kHz mono AAC.

Mathematical addition of opposite-phase waves · fail

Around 47–54 seconds, equal-frequency, equal-amplitude sinusoids separated by pi are shown producing a residual. They cancel exactly; the purple residual is drawn independently rather than computed as their sum, contradicting the plus/equality symbols.

Pausing music and external noise · partial

The opening pairs music-paused graphics with falling amplitude labelled external steady hum, suggesting that pausing music lowers external noise. Later explanations of an independent loop and local cancellation inside the earcup are correct.

Loop, seal and operating limits · pass

The microphone → processor → speaker loop and passive/active roles are clear. Residual noise and difficulty fully removing speech are retained, with explicit limits on whole-cabin silence and measurement claims.

Caption timing and embedded subtitles · pass

All 15 SRT cues have valid times tied to real TTS segment samples. Text and timecodes extracted from the MP4 mov_text stream match the original SRT.

Measured narration and mix · partial

The 86.15-second Kokoro voice matches text/audio receipt hashes without tempo or pitch changes. The music/effects bed is about 13dB below voice RMS and the final soundtrack is padded to 88.15 seconds. No listening review was performed.
