* polish(tinytorch/diagrams): align 23 Lab Guide SVGs with book style guide
The hand-authored diagrams under tinytorch/quarto/assets/images/diagrams/
were drifting from the ML Systems SVG style guide — they used Tailwind
CSS greys and custom oranges instead of the book palette. This made them
visually clash with the canonical big-picture-module-flow.svg (under
assets/images/svg/) and with every other diagram in the textbook.
Normalize to book style:
- Fills: #f4f5f7, #f8f9fa, #e5e7eb → #f7f7f7 / #bbb (book neutrals)
- Text: #1f2937, #6b7280 → #333 / #999 (book text hierarchy)
- Arrows: #9ca3af → #555 (book neutral stroke)
- Accent orange: #fff1e8 / #ff8246 → #fdebd0 / #c87b2a (book routing)
- Corner radius: rx="2" → rx="4" per style-guide standard
- Stroke width: flat "1" → "1.2" (secondary tier per style guide)
- Section titles: font-size="11" (bold) → "12" per style-guide headers
No content, layout, or positional changes — only style-token swaps.
All 23 SVGs re-validated as well-formed XML.
Side effect: the orphan diagrams/00_big-picture-module-flow.svg is also
normalized. The canonical big-picture is under assets/images/svg/ and
was already book-styled (not touched by this pass).
* polish(tinytorch/01_tensor): port Cache Tiling systems callout from ABOUT.md
The stashed work from the tinytorch-updates branch included a Cache
Tiling "Systems Implication" callout for Module 01, but it lived in
tinytorch/src/01_tensor/ABOUT.md — a path that was retired when the
module docs consolidated into tinytorch/quarto/modules/. The companion
"Contiguous Memory & Strides" callout from the same stash already made
it over during the consolidation; this one got left behind.
Insert the callout right after the matmul O(n³) explanation (the
natural bridge into "why does the naive loop lose to BLAS?"), and
before the Shape Manipulation section. Progressive-disclosure check:
every concept the callout introduces (cache misses, BLAS, O(n³) vs
O(n²)) is already on the page or introduced inline in the callout
itself (Memory-Bound / Compute-Bound are defined parenthetically).
The pattern matches the existing book-style sidebar on line 587.
* deps: bump TypeScript 5→6, @types/node 20→25, ipykernel 6→7
Resolves 9 stale Dependabot PRs (#1494, #1497, #1490, #1491, #1479,
#1477, #1475, #1467, #1454) whose package-lock conflicts blocked
auto-rebase.
VSCode extensions: bump TypeScript devDep to ^6.0.3 and @types/node to
^25.6.0 across book-ext, mlsysim-ext, labs-ext, kits-ext, tinytorch-ext.
Regenerate lockfiles.
TypeScript 6.0 no longer auto-includes ambient @types packages; add
explicit "types": ["node", "vscode"] to each tsconfig so
child_process / fs / Buffer / vscode API types continue to resolve.
All 5 extensions now compile clean with TS 6.0.3 + @types/node 25.6.0.
TinyTorch: bump ipykernel floor to >=7.2.0 in pyproject.toml,
requirements.txt, and binder/requirements.txt.
Notebooks use short names (tensor.ipynb, not 01_tensor.ipynb) but docs
and Binder postBuild scripts used the prefixed form. This caused broken
Binder links and incorrect paths in troubleshooting guides.
Fixes: harvard-edge/cs249r_book#1176
- Update all repository references to point to harvard-edge/cs249r_book
- Fix Binder URLs to include tinytorch/ path prefix
- Fix Colab URLs to include tinytorch/ path prefix
- Update marimo-badges.js with correct repo and path
- Fix dataset documentation URLs
- Update module ABOUT.md files with correct source links
