Disclosure: This article was prepared with AI assistance for the H3Max operations team. The LemoLab film is a third-party reference, and no local reproduction is claimed.
Open the H3Max entry for this debugging reference as a context reference, while keeping it separate from the local debugging workflow. The page does not establish that H3Max can run this repository, control a terminal, or reproduce the film.
The reference case is LemoLab’s Clawd Moves In, a 59.4-second unofficial fan film. Compare against the distributed film for the debugging baseline and the retained movie alongside the symptom comparisons. The production repository for classifying debug evidence attributes it to Claude Opus 5.5, but those model sessions have not been independently verified here. This is not an H3Max benchmark.

For debugging, use one chain for every problem:
symptom → reproduction comparison → suspected layer → smallest fix → new evidence
Do not start with “change the animation.” Start by classifying what changed.
The visual specification for the debugging triage says the UI is rebuilt in HTML/CSS/SVG, the cursor represents the user, and Clawd represents software activity. Plan/diff/test figures are authored demo content, not benchmarks.
Hypothetical failure 1: a layout change moves Clawd off the edge
This is a hypothetical debugging example, not a reported observation.
Symptom: after a font or pane-layout change, Clawd appears slightly above or below the intended UI edge.
Reproduction comparison: compare the same landing before and after the layout change, including neighboring frames and camera framing.
Suspected layer: font metrics → DOM geometry → measured anchor → sprite contact.
Smallest fix: re-measure or correct the affected anchor logic. Do not start by adding an arbitrary sprite offset.
New evidence: fresh boundary frames showing the corrected contact, plus confirmation that readable text and captions are still clear.
Hypothetical failure 2: backward seeking produces another state
Again, this is a hypothetical case.
Symptom: timestamp T looks correct in normal playback but shows another theme, pane, camera, or Clawd state after seeking backward from a later time.
Reproduction comparison: compare T through fresh/direct/forward and backward paths.
Suspected layer: accumulated state, timer behavior, class mutation, or missing reset.
Smallest fix: make the affected scene state derive from absolute time rather than playback history.
New evidence: matching observable state at T across the different seek paths.
The scene chronology used for the seek comparison helps define what Prompt, Plan, Review, and Self-check should look like at a given part of the timeline.
Original frame at 28.512 seconds. It is reconstructed interface animation, not evidence of a live coding session.
Hypothetical failure 3: regenerated voice leaves fixed captions or foley behind
This is also hypothetical, not an observed defect in the source film.
Symptom: narration changes, but a landing, caption hold, camera cue, or foley event still behaves as if the old timing were active.
Reproduction comparison: compare old and regenerated word timings, then inspect every relevant W(id, word) dependency.
Suspected layer: compare the voice/word timings/W(id, word) chain with captions and foley fixed to absolute time. A fixed event may stay behind while a word-linked cue moves.
Smallest fix: update only the downstream cue that is genuinely stale. Do not compensate for a timing defect by changing unrelated geometry.
New evidence: reviewed word timings, fresh boundary frames, caption duration check, and listening confirmation around important word onsets.
A transcript match is not enough if foley masks the speech or the caption disappears before it can be read.
Reproduction and evidence appendix
Before running commands, confirm Git, Node 20+, FFmpeg/ffprobe, and Python 3.11–3.13 or uv. Use a fresh clone or reviewed copy, preserve the lockfile and actual local source, and do not overwrite an existing project.
git clone https://github.com/lemomo-ai/lemo-opuscar.git clawd-case
cd clawd-case
export LEMO_OPUSCAR_HOME="$PWD"
sh plugin/skills/lemo-opuscar/scripts/setup.sh deps voice
for BANK in salamander freepats karoryfer vcsl vsco2ce; do
sh tools/fetch.sh instruments "$BANK"
done
mkdir -p evidence
D=styles/living-screencast/demo
git rev-parse HEAD > evidence/clawd-commit.txt
npm ls --depth=0 > evidence/clawd-dependencies.txt
Preserve all five banks: salamander, freepats, karoryfer, vcsl, and vsco2ce.
Verify the current source before relying on 59.4 seconds at 30 fps. If unchanged, the expected picture count is 1,782 frames.
This prompt is newly written for this tutorial and is not recovered from the author’s original prompt or session:
Reproduce and analyze Clawd Moves In from the living-screencast demo source.
Inspect the current commit, locks, STYLE.md, DEMO.md, CREDITS, core APIs,
and demo/build.sh. Read the author MP4 and actual local files first.
Keep it an attributed unofficial fan-film reproduction. Do not claim the
reconstructed UI is a real recording or that its tests ran on H3Max. Preserve
Clawd's terminal-to-app journey, the existing chapters, and coherent demo data.
Report discrepancies with current product documentation without inventing new
features. No replacement stock footage or external image/video generation.
Inspect film.js, ui.js, clawd.js, main.js, voice files, word timings, and sound.py.
Explain the dependency plan and source duration/fps before building. Use the
source's 59.4 seconds and 30 fps only after checking them.
Keep crisp pixel-grid acting, a smoothly moving cursor, and a continuous camera.
Measure DOM anchors so Clawd lands on real element edges. Reserve text-free
space for the mascot and captions. Derive all scene state from absolute time;
reverse and arbitrary seeks must reproduce the same state in this environment.
If speech is regenerated, review every line and its word times before relying
on W(id, word) cues. Preserve original credits and fan-film disclosure. Use the
actual build/export interfaces. Save model/provider/effort logs, prompts,
modifications, frame checks, and the full output. Do not publish or report
an untested reconstruction as successful.
For intentional narration regeneration, use the narration build path for reproducing cue changes:
sh styles/living-screencast/demo/build.sh --vo
--vo regenerates narration. Review the generated audio and word timings before accepting them. Without it, usable existing voice assets are required. Current source uses 30 fps and six capture workers; do not invent another worker CLI flag.
Generate comparison stills:
node core/render/still.mjs "$D" 0 8.9 23 32 40.9 56 \
--out evidence/clawd-stills
For each symptom, add adjacent frames around the actual boundary being investigated. A still alone cannot reveal teleporting or audio masking.
Finally validate the artifact:
ffprobe -v error -count_frames -show_streams -show_format -of json \
styles/living-screencast/living-screencast.mp4
ffmpeg -v error -i styles/living-screencast/living-screencast.mp4 -f null -
Original frame at 48.114 seconds from the published LemoLab film. Animated interface and live operation remain separate.
Record actual duration, frame count, narration, subtitles, and the unofficial-fan-film disclosure. Do not claim byte identity with the web release unless supported by actual evidence.
Close the debug handoff with the asset inventory to retain with the debug evidence. MIT covers the repository code, not automatically Anthropic’s character/interface identity, OFL fonts, or third-party instrument samples.
The debugging discipline is therefore: reproduce the symptom, classify its layer, change the smallest responsible dependency, then create new evidence for that specific fix.
