Add interactive study note on World Models (Ha & Schmidhuber)#33
Merged
Conversation
- README: rewrite Structure/CI sections to match the actual tree and workflow (removed references to nonexistent head/header/footer.html, about.md, blog.md; correct the CI trigger description). - Gemfile: drop unused jekyll-seo-tag (meta is hand-rolled in _includes/meta.html); add html-proofer in a :test group for CI. - Remove dead Disqus code (site.disqus was never configured, so it never rendered): delete _includes/disqus.html and its include in post.html. - default.html: remove the IE<9 html5shiv block (dead http:// googlecode URL) and the leftover "Created with Jekyll Now" comment. - Harden insecure/protocol-relative URLs to https:// (svg-icons StackOverflow link, GoatCounter analytics script). - _config.yml: trim empty footer-links template fields; drop CNAME from exclude (the file no longer exists). - Commit Gemfile.lock for reproducible builds (un-ignore it). - CI: add a pull_request job that runs jekyll build + html-proofer (internal links/images, UTF-8 locale) so branches are verified before merge; gate the CV-build/deploy job to non-PR events. - CLAUDE.md: generalize the stale hard-coded development-branch reference.

html-proofer 5.2.1 pulls in async → console 1.36, which requires Ruby >= 3.3. The workflow pinned Ruby 3.2, so `bundle install` failed to resolve the locked gems. Bump both jobs to Ruby 3.3 to match the committed Gemfile.lock, and update the matching note in CLAUDE.md.

Adds a skill at .claude/skills/add-study-note/ that scaffolds, fact-checks, and previews the site's interactive Study Note posts: - driver.mjs: builds the Jekyll site and screenshots a note in light + dark with headless Chrome (puppeteer-core + chrome-headless-shell), plus the /study-notes/ index, so a new note can be verified visually before push. - template.html: a conventions-correct scaffold (.study-note wrapper, --sn-* tokens, slider demo, adaptive SVG chart with the theme MutationObserver). - SKILL.md: the authoring workflow — research/fact-check with /deep-research, write per docs/_posts/CLAUDE.md, then preview via the driver. Documents the rbenv jekyll-binstub workaround and the placeholder-date build gotcha. node_modules/ and screenshots/ are gitignored (regenerated artifacts).

A standalone study note explaining the World Models paper: the V/M/C split (VAE vision, MDN-RNN memory, tiny CMA-ES controller), training the controller inside the model's dreamed rollouts, and the temperature knob behind the cheating/sweet-spot trade-off. Three theme-aware vanilla-JS demos: - V->M->C pipeline plus a latent-bottleneck canvas (compression trade-off) - an MDN-RNN "dream" rollout whose futures collapse or fan out with tau - the paper's actual VizDoom Take Cover dream-vs-real temperature sweep Follows the study-note design system (--sn-* tokens, MutationObserver redraw) and cross-links the temperature/entropy and MDP notes.

What
A new interactive Study Note explaining the World Models paper (David Ha & Jürgen Schmidhuber, 2018) — a standalone
layout: postHTML file atdocs/_posts/2026-06-23-world-models.html, live at/world-models/.It teaches the paper concept-first: the agent splits into a large world model trained unsupervised plus a tiny controller trained by evolution:
z.[z, h], trained with CMA-ES.Three interactive, theme-aware demos (vanilla JS)
Conventions
--sn-*tokens only, theMutationObserverredraw pattern (including manual canvas re-theming), concept-first voice.Verification
Built the site and screenshotted the note in light and dark plus the
/study-notes/index via theadd-study-notedriver. Confirmed: all demos render, dark mode is genuinely dark with the canvas re-themed, Demo B collapses/fans with τ, Demo C shows the inverted-U, and the note appears on the index with its excerpt.🤖 Generated with Claude Code
