runView passed `easy ? section : null` straight to Node.append(), which prints a null as the text "null". Spread the Simple-only section instead. AI-Assisted: Claude Code with Claude Opus 5.5; found the stray text while recording the walkthrough and wrote the fix Co-Authored-By: Claude Opus 5.5 <[email protected]>
- scripts/media/walkthrough.mjs renders assets/walkthrough.mp4 (with a poster and .vtt captions): npx penthera, an offline scan of the mock server, penthera ui --demo in Simple and Advanced mode, one fix approved, the owner report. The dashboard part is headless Chrome over CDP, recorded with Page.startScreencast; the terminal parts are VHS tapes in scripts/media/tapes/. Demo data only, every server on 127.0.0.1. - The Demo media workflow renders the video too and adds it to its PR. - scan.tape writes the README hero (assets/demo.gif) directly and scans with --offline. The agents and deps-diff tapes rendered a "Cannot find module" error (relative bin path after cd); they use an absolute path. - Tapes use a black and white theme with the #0000ed accent, as the dashboard does. - README and docs/index.md link the video under the screenshots. AI-Assisted: Claude Code with Claude Opus 5.5; wrote the recording script and tapes, rendered the media and the doc links Co-Authored-By: Claude Opus 5.5 <[email protected]>

Demo media for 1.8.0, after #63. No version bump. CHANGELOG entries are under [Unreleased] → Docs (and one line under Fixed).
The walkthrough (
assets/walkthrough.mp4, 82 s, 1.5 MB, H.264, no audio, captions burned in and inassets/walkthrough.vtt, posterassets/walkthrough-poster.jpg):npx penthera: the setup wizard on a scratch copy oftests/fixtures/init/apppenthera http://127.0.0.1:8765 --offline: the mock serverpenthera ui --demo: setup, then Simple mode (verdict, first problem), then Advanced (triage matrix, a finding)node scripts/media/walkthrough.mjsre-renders all of it. The terminal parts are VHS tapes inscripts/media/tapes/. The dashboard part runs headless Chrome over CDP, building onscripts/dashboard-screenshots.mjsand its fragment login (#70), and records withPage.startScreencast. That is the mechanism Playwright's video uses, so this adds no Playwright dependency. It uses demo data only:--demo, the mock server, a scratch git repo with a[email protected]identity, and every server on 127.0.0.1.npxis a shell function inside the tape, so the clip runs this checkout and never fetches from npm.GIFs
scan.tapenow writes the README heroassets/demo.gifdirectly (it used to writedemo-scan.gif), and scans with--offline.agentsanddeps-difftapes were broken on main: they rendered aCannot find module …/bin/penthera.jsstack trace, because they used a relative path aftercd. Both are fixed, anddemo-agents.gifanddemo-deps-diff.gifare committed.Workflow:
demo-media.ymlrenders the video after the tapes (CHROME=google-chrome, preinstalled on ubuntu-latest), uploads it with the GIFs, and adds it to the media PR. The script fails if the video goes over 8 MB, and it warns if the length falls outside 60 to 90 s. I have not run the workflow on GitHub; a dry run from the Actions tab would confirm it on Linux.One UI fix (its own commit): in Advanced mode, a run transcript showed a stray
nullunder its title, becauseNode.append(null)prints "null". It showed up in the recording.Checks:
npm run audit:internalpasses every gate: 1034 tests, pack 195 files, 716 KB packed against the 781 KB budget, and 0 broken links in 354. Assets are not infiles. Lint is clean, andscripts/ci/provenance.mjspasses.Not in this PR: the CLI says "ai tooling" in lower case under "What next", and the owner report spells "defence". Both are product copy, left for a separate change.
