* 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.
- Unify publisher to 'mlsysbook' across all four extensions (tinytorch was 'tinytorch')
- Remove redundant onView: activation events (VS Code auto-generates from views declaration)
- Add workspaceContains: activation event to tinytorch (was empty)
- Add configurationDefaults with workbench.tree.indent: 16 to book, mlsysim, labs (tinytorch had it)
Use vscode.openWith(uri, 'jupyter-notebook') for .ipynb files so they
render in VS Code's notebook editor with cell support, rather than
opening as raw JSON text via openTextDocument.
The VS Code extension no longer implements any business logic — every
capability (module discovery, path resolution, system info, builds,
tests, clean) lives in Tito CLI commands. The extension is a pure UI
shell that delegates via `python3 -m tito.main`.
Tito CLI additions:
- `module list --json` for machine-readable module discovery
- `module path <num> --notebook|--source|--about` for file resolution
- `system info --json` for environment info
- `dev build html|serve|pdf|paper` wrapping make targets
- `dev clean [all|site]` wrapping make clean
- Banner suppression for --json and module path output
Extension hardening:
- Centralized CLI integration in utils/tito.ts (single TITO_CMD constant,
callTito, callTitoJson, titoTerminalCommand, isTitoAvailable, log/logError)
- Replaced all silent catch{} blocks with logged errors and user feedback
- Module tree shows error/empty states with actionable Setup/Health buttons
- Info tree shows "Tito CLI unavailable" when CLI is unreachable
- Removed all setTimeout refresh hacks — file watcher on .tito/progress.json
is the sole refresh mechanism
- Exit code tracking via onDidEndTerminalShellExecution
- Tito availability pre-flight check on activation
- BUILD_OUTPUTS constants for build artifact paths
- Zero execSync calls outside tito.ts, zero hardcoded command strings
Add the TinyTorch VS Code extension source package and align module code/docs references so APIs, milestones, and progression notes remain consistent across the curriculum.
