Quarto renders chapters at contents/vol{N}/{chapter}/{chapter}.html
(depth 3 from site root), which deployed as the double-nested URL
mlsysbook.ai/vol{N}/contents/vol{N}/{chapter}/{chapter}.html.
Fixes:
- Add .github/scripts/flatten-vol-urls.sh: post-build script that
moves contents/vol{N}/* to site root, fixes relative asset paths
(../../../ → ../), search.json hrefs, sitemap.xml, and absolute
URL refs in moved HTML files.
- book-publish-live.yml: run flatten script after artifact download,
before release manifests, for both vol1-site and vol2-site.
- book-preview-dev.yml: add flatten-vol-urls.sh to sparse checkout
and run flatten before rewrite-dev-urls so depth is correct.
- cloudflare-redirects.json: update all 37 "to" values to clean
/vol{N}/{chapter}/... form; add 33 backward-compat entries for
existing /vol{N}/contents/vol{N}/... live URLs.
- instructors/*.qmd: update 77 chapter hrefs to clean URL form.
Source fixes (instructors/*.qmd):
- Replace all short-form /vol1/{slug}.html URLs with correct full paths
/vol1/contents/vol1/{chapter}/{chapter}.html across course-map, foundations-
syllabus, scale-syllabus, tinyml-syllabus, getting-started, ta-guide
- Fix renamed chapter slugs: dl_primer→nn_computation, efficient_ai→
optimizations/model_compression, serving→model_serving, ops→ml_ops,
responsible_ai→responsible_engr (vol1), on_device_inference→model_serving
- Same pattern for all /vol2/{slug}.html → /vol2/contents/vol2/...
- Update broken tinytorch/INSTRUCTOR.html link to tinytorch/ index
Cloudflare redirects (external inbound traffic):
- Add shared/config/cloudflare-redirects.json with 37 301 redirects covering
all broken short-form chapter URLs
- Add infra-cloudflare-redirects.yml workflow that syncs the JSON to
Cloudflare's Redirect Rules API on every push to dev/main; uses
secrets.CLOUDFLARE_REDIRECTS_TOKEN (separate from Cache Purge token)
Link checker gap (root cause of missed 404s):
- Add shared/config/.lycheeignore-nightly without the blanket mlsysbook.ai
exclusion that was silently swallowing all broken internal links
- Update infra-link-rot-nightly.yml to use .lycheeignore-nightly so the
nightly sweep now catches broken mlsysbook.ai links that are live post-deploy
Add shared/config/_ecosystem-cards.qmd: one source of truth for the
'Part of the MLSysBook Ecosystem' section (full 7-member set). Each landing
page includes it; a small script marks the current site 'You are here' by
reading that site's own release-manifest meta, so one block shows each page
its own state. Replace the divergent inline sections in kits (3 hand-written
cards) and labs (prose paragraph); add the section to slides, instructors,
and mlsysim.
Add shared/config/footer-common.yml (mirrors navbar-common.yml) and point
slides, labs, kits, and instructors at it via metadata-files, replacing their
drifted inline footers. The release pill now lives in the footer right slot
(not dangling below the page) as a fixed muted-gray chip, pinned so it looks
identical regardless of each site's theme accent. mlsysim and the book keep
their own footers (dual license / build stamp) but carry the same pill span.
release-pill.html is now assets-only and populates every data-release-pill
span from each site's own release-manifest.
Every subsite's announcement bar Line 1 carried a 'Start reading →' / 'Start building →' / 'Get started →' link that pointed at the very subsite the reader was already on. Clicking it was a no-op self-navigation.
Strip the CTA from Line 1 across all 8 sites that have the regression:
- announcement-vol1.yml drop 'Start reading →'
- announcement-vol2.yml drop 'Start reading →'
- tinytorch drop 'Start building →'
- mlsysim drop 'Get started →'
- kits drop 'Get started →'
- labs drop 'Preview →'
- slides drop 'Browse decks →'
- instructors drop 'Start here →'
Line 1 keeps the bold identity statement, which is what readers came for. The other lines (Vol I / II links, sibling row, newsletter CTA) keep their navigations since they DO lead somewhere new.
announcement-book.yml is unchanged — its Line 1 already points at the ecosystem root (https://mlsysbook.ai/), not at /book/ where the reader is.
For the public launch, every site's "Alongside the book" (or "Build
with your students") row now lists StaffML alongside TinyTorch, Hardware
Kits, MLSys·im, and Labs. Two coupled changes:
• StaffML appended with verb "practice" — pairs cleanly with the
existing verbs (build / deploy / model / explore / practice).
• MLSys·im verb changed from "simulate" to "model" to match the
project's own self-description ("first-principles analytical
modeling for ML training and inference; model the physics before
you build"). MLSys·im is analytical, not Monte-Carlo simulation;
the new verb is more honest and the audience reads it cleanly.
Also restores tinytorch/quarto/config/announcement.yml to the canonical
4-line ecosystem template. That file had been silently rewritten to a
release-only banner ("🎉 v0.1.11 released — ...") by the
tinytorch-publish-live workflow, dropping the ecosystem cross-links
entirely. Restoration here; workflow fix is a separate commit.
Per-site row state after this commit (each site omits itself):
site, vol1, vol2: TinyTorch · Kits · MLSys·im · Labs · StaffML
instructors: TinyTorch · Kits · Slides · StaffML
kits: TinyTorch · MLSys·im · Labs · StaffML
labs: TinyTorch · Kits · MLSys·im · StaffML
mlsysim: TinyTorch · Kits · Labs · StaffML
tinytorch: Kits · MLSys·im · Labs · StaffML
slides: (teacher-focused row, unchanged)
The staffml site itself has its own Next.js ecosystem navbar
(EcosystemBar.tsx) which is out of scope for this Quarto-only sweep
and audited separately.
The .inv-table cells and .footer-cta card hardcoded light colors that
made text invisible against the dark theme. Added dark-mode overrides
for column text, hover row, last-column links, and the CTA card.
Markdown blockquotes (e.g. the Sample Decision Log entries on the
Assessment page) inherited Quarto's light-mode text color, leaving the
content nearly unreadable on the dark background. Style blockquotes
with the dark-mode body color, elevated surface, and indigo left border.
Mirrors the kits fix (#1623): navbar submenus rendered with a white
background in dark mode. Sets dropdown surface, items, headers, and
dividers to the Blueprint dark palette with indigo hover/active.
The sidebar entry pointed to https://mlsysbook.ai/tinytorch/INSTRUCTOR.html
which 404s — INSTRUCTOR.md lives in tinytorch/ but is not part of the
TinyTorch Quarto project (tinytorch/quarto/), so it never gets rendered
or published.
Point at the canonical GitHub source instead until the TinyTorch site
is updated to publish the instructor guide as a real page.
The dark-mode rule targeted .sidebar .sidebar-item a, but the rendered
sidebar uses a.sidebar-link and a.sidebar-item-toggle directly, so the
section headers and leaf links inherited the light theme and were
unreadable on the dark background.
Target the actual selectors (sidebar-link, sidebar-item-toggle,
menu-text), and cover the search input and TOC rail with the same
indigo accent.
Lab subtitles from Week 10 onward were shifted one position ahead of the
actual lab content. The URLs were correct (clicking would open the right
lab) but the displayed names described the wrong lab, misleading instructors
about what each week's lab covers.
Corrected subtitles cross-checked against each lab file's opening title:
- Lab 09: "Quantization (INT8/INT4)" → "The Data Selection Paradox"
- Lab 10: "The Roofline Model" → "The Compression Paradox"
- Lab 11: "Benchmarking Methodology" → "The Hardware Roofline"
- Lab 12: "Tail Latency (P99)" → "The Benchmarking Trap"
- Lab 13: "Drift Detection" → "The Tail Latency Trap"
- Lab 14: "Fairness and Efficiency" → "The Silent Degradation Problem"
- Lab 15: "Capstone Integration" → "No Free Fairness"
Local rendering of the previous redesign showed text bleed on the
longer secondary labels — "Hardware Kits: Reality" and
"TinyTorch: Implementation" sat right at the box edges with no inner
padding, "Labs: Simulation & Discovery" overflowed the rect bounds
on Safari. Per gemini-2.5-flash review (the user's preferred
gemini-3.1-pro-preview was at quota cap):
- Pillar box width 140 -> 170 px (extra ~7px padding either side
of the longest label).
- X coordinates of READ/EXPLORE shifted from 270 -> 255 to keep
them centred at x=340; BUILD shifted 475 -> 460 and DEPLOY
65 -> 50 to keep their outer edges aligned with the canvas
margin.
- Box centres unchanged, so the emoji + title + sublabel rows
stay vertically aligned.
- Re-snapped the four loop-arrow paths to the new box edges so
each marker terminates exactly at the perpendicular border:
READ→BUILD : M425,135 Q500,135 500,195
BUILD→EXPLORE : M500,265 Q500,345 425,345
EXPLORE→DEPLOY : M255,345 Q180,345 180,265
DEPLOY→READ : M180,195 Q180,135 255,135
- Y coords of arrow labels and annotation card text snapped to
the 5/10px grid (gemini change retained).
Verified by local render: no text spills outside any pillar; all
four arrows close into their target box edges; loop reads
clockwise; semantic palette unchanged.
The four-pillar-loop.svg used pill-shape boxes (`rx="12"`), bright
non-semantic accent colors (indigo, mint-green, amber, rose), and
indigo arrow markers — none of which matched .claude/rules/svg-style.md.
Reads as inconsistent next to vol1/vol2 figures and instructor-hub
material.
Changes (geometry preserved, only style):
- Box corners: rx="12" → rx="4" (standard process boxes per spec).
- Annotation cards: rx="6" → rx="4".
- Color roles mapped to the canonical semantic palette:
READ : compute blue (#cfe2f3 / #4a90c4)
BUILD : data-flow green (#d4edda / #3d9e5a)
EXPLORE : routing orange (#fdebd0 / #c87b2a)
DEPLOY : error/cost red (#f9d6d5 / #c44)
Center / annotations : neutral container (#f7f7f7 / #bbb)
- Arrow markers: indigo (#6366f1) → neutral (#555) per spec default.
- Loop arrow paths still curve around the center hub (cyclic
topology is the figure's content), but pulled clear of box
fills to avoid stroke-through-box defects.
- Title moved to canonical y=30 (was y=35).
- Footnote moved to canonical y=448 (was y=420), italic muted #999.
- Annotation cards widened to 180×40 to clear the footnote band.
- All coordinates snapped to 5/10px grid.
- Typography sizes tightened to the spec scale (titles 11/13,
secondary labels 9, sub 8).
Adds the Tier B (lite) versioning pattern to all three Quarto-only
sites in one commit — they have identical shape, so fragmenting would
add review burden without isolation benefit.
For each project:
- workflow_dispatch inputs: release_type/description/site_only/
explicit_version/confirm. Same shape as Tier A workflows so
operators see one consistent UI across the monorepo.
- New `prepare:` job calls _release-prepare.yml with tier=B and the
project's previous_tag_pattern.
- New manifest emit step before deploy: hashes the project's content
directory (excluding _build, .quarto, etc.) and writes
release-manifest.json into the build output. URL convention
matches the deploy path: /kits/, /labs/, /instructors/.
- New create-tag job: tags <project>-v<release_id> on success.
Tier B intentionally skips AI-generated release notes — the
description plus auto-generated commit list (where available) is
sufficient given the rapid iteration cadence and lower citation
stakes than book/staffml/tinytorch/mlsysim.
- Quarto _quarto.yml: <meta name="release-manifest"> in
include-in-header and shared/release/release-pill.html in
include-after-body.
No changes to Marimo notebook structure (labs), Quarto build commands,
PDF builds, or any project's content files.
Iterates on the post-merge 404 redesign across all 8 sub-sites:
- SVG roofline-plot fonts bumped for readability without changing
layout: axis labels 9.5pt to 14pt, region labels 9.5pt to 14pt,
title and "your page (404)" annotation 11pt to 16pt.
- Random-joke font shrunk from 1.6rem to 1.3rem (1.1rem on mobile)
so the joke no longer dominates the SVG above it.
- Removed the static "Looks like this page slipped past our load
balancer" subline from 6 sub-sites — it read as a competing static
joke alongside the random rotation. Slides and instructors keep
their informational sublines.
- Joke pool tightened 97 to 79 via a strict ML-systems-centric test:
if you could swap "page" for any generic web/ops resource and the
joke still works, cut. Cuts removed the H&P canonical material
(Amdahl's Law, TLB miss, Dennard scaling, false sharing, fat-tree
topology) that is general computer architecture rather than ML
systems specifically. 19 borderline jokes were rewritten to anchor
punchlines in concepts only ML practitioners decode (KV cache,
gradient AllReduce, prefill, ZeRO, speculative-decode acceptance,
1F1B schedule, ridge point, BPE merges).
Replace the inline-game 404 across all 8 sub-sites with a unified
design: roofline-plot illustration, random pick from a 97-joke
editorial-curated pool, dual CTA (home + playground), and a
GitHub-issue-backed contribute link for community submissions.
The joke pool was curated through a multi-agent editorial process:
4 generators (each with a different ML systems lens) produced 240
candidates; 5 reviewer personas (architect, NLP researcher, production
engineer, undergrad, copy editor) scored each; the synthesizer kept 92
surviving jokes plus 5 new canonical-architecture additions (Amdahl,
TLB, Dennard, false sharing, fat-tree topology) the architect flagged
as missing from the H&P-tradition canon.
Self-contained CSS with prefers-color-scheme: dark adapts to host
themes without coupling to each sub-site's bespoke styling. SVG
follows the book's semantic palette (blue memory-bound slope, green
compute roof, MIT red error annotation). Per-site navigation
preserved across all sub-sites.
Adds .github/ISSUE_TEMPLATE/404_joke.yml so contributions arrive
structured (joke text, theme dropdown, license checkbox) and
auto-tagged (site, 404-joke, good-first-issue) for triage.
- Added 'KV Cache Packer' to teach PagedAttention and KV fragmentation
- Added 'Cluster Commander' to teach Slurm scheduling and fleet fragmentation
- Registered all 14 games in the runtime registry
- Fixed WebGL rendering loops to avoid performance overhead and crashes
- Updated 404 pages across all workspaces to route to the new games Playground
- Overrode default Quarto 'S' search shortcut to Shift+? to free up typing controls
Align the MLSys·im code, docs, paper, website, workflows, and lab wheel for the 0.1.1 release. This also fixes runtime/API issues found during release review and prepares the paper PDF plus archive package.
Align public README and site messaging around the curriculum components, adoption paths, and current early-release status so newcomers can move from reading to building, deployment, practice, and teaching.
Every site's announcement bar now follows one template:
Line 1 — identity + primary CTA (what is THIS site)
Line 2 — the book (or, on book sites, the other volume)
Line 3 — "Alongside the book:" sibling row (3 most-relevant verbs)
Line 4 — newsletter
The book is the anchor of the curriculum; every other site is a verb
applied to it — TinyTorch (build), Hardware Kits (deploy), MLSys·im
(simulate), Labs (explore), Slides + Instructors (teach). Making that
shape visible in every bar turns nine independent sites into chapters
of one curriculum.
Removed stale copy: "Happy New Year!" on kits + labs, "coming in 2026"
on labs (we are in 2026; replaced with "Coming Summer 2026"), TinyTorch
v0.1.10 single-line release notice (belonged in a release changelog,
not the always-visible nav bar).
Normalized outbound links: /book -> /vol1/ and /vol2/, consistent
trailing-slash hygiene on every URL. Newsletter link points to
https://mlsysbook.ai/newsletter/ (the actual Quarto page) instead of
#subscribe (which only resolves on the landing page).
The landing site (mlsysbook.ai) uses a 5-line variant that covers all
four learner verbs + the teacher-tools row; every other site uses the
4-line form.
StaffML is a Next.js app, not a Quarto site, so its banner is out of
scope for this PR and will ship as a separate React component change.
Add `text` language tag to 25 unlabeled fenced code blocks across the
public-facing READMEs. Mostly directory-tree listings, all-contributors
bot instructions, and pseudo-output ASCII blocks — none were getting
syntax highlighting anyway, but the explicit tag silences markdownlint
MD040 and signals intent ("this is plain text, not a forgotten lang").
GitHub's github-markdown-css applies:
.markdown-body table { display: block; width: max-content; max-width: 100%; }
The HTML width="100%" attribute is a presentational hint with lower
specificity than the class selector, so tables with short cell content
were sizing to max-content and not stretching to fill the column.
Tables with long sentences per cell stretched fine, masking the bug.
Add inline style="width:100%" (specificity 1,0,0,0) which overrides
the class-selector rule. Keep width="100%" attribute as a fallback for
non-GitHub renderers (VSCode preview, GitLab, plain HTML viewers).
54 tables updated across 10 READMEs + the two contributor-sync scripts
that regenerate auto-managed tables.
The sub-project READMEs used an old-school nested-table card design
with hardcoded bgcolor="#ffffff", "#cfd6dd", "#eef2f7" plus deprecated
HTML4 attributes (cellpadding, cellspacing, border). It looked good in
light mode but produced harsh white islands in GitHub's dark theme,
which is what most readers see today.
Across 11 sub-READMEs:
- Strip the card wrapper so data tables are just clean
<table width="100%"> with semantic <thead>/<tbody>. Headers keep
their column widths; bgcolor/valign/zebra-stripe cruft is removed
(GitHub provides its own theme-aware striping).
- Convert the early-release callouts (and mlperf-edu's two-tier
status block + "source of truth" note + interviews' two info boxes)
to GitHub-native > [!NOTE] / > [!WARNING] / > [!TIP] callouts.
These are theme-aware, get proper icons, and render correctly in
light AND dark mode.
Net result: 528 lines of HTML cruft removed, 230 lines of clean
markdown added. Visual identity is preserved (callouts still stand
out, tables still stretch full-width) while becoming dark-mode safe
and consistent with the main README.
Add `width="100%"` to every HTML content and contributor table across all
project READMEs so they render full-width on GitHub instead of collapsing
to natural content width. Cell-level `width="X%"` percentages were already
in place but only take effect once the table itself has an explicit width.
Also update the contributor-sync scripts so the auto-generated tables stay
consistent on the next bot run:
- .github/workflows/contributors/generate_main_readme.py
- .github/workflows/contributors/generate_readme_tables.py
Scope: 27 files, 85 tables. Sub-project READMEs that already use the
"card" pattern (labs/, kits/ content sections with <table width="98%">
wrappers) are intentionally untouched.
The Resources sidebar in instructors/_quarto.yml advertised a "Labs
Instructor Guide" pointing at /labs/INSTRUCTOR_GUIDE.html, but no such
file exists anywhere in the labs/ source tree — so the link has always
404'd. Playwright smoke against the live instructor site picks this up
as a hard broken link.
Drop the entry. If a labs instructor guide is authored in the future,
re-add with a real href.
- Add wrap_readme_data_tables.py to frame <table>+<thead>/<tbody> blocks in a
98% width panel (#cfd6dd border, #eef2f7 headers, zebra body rows where
applied manually in converted tables).
- Apply wraps to book, kits, labs, slides, tinytorch; tbody wraps for kits
docs/related and instructors overview.
- Convert remaining Markdown tables in mlsysim, mlperf-edu, and interviews to
the same HTML pattern; replace StaffML markdown callouts with HTML panels.
- Add thead rows to kits/instructors body-only tables for clearer hierarchy.
Replace markdown blockquotes with a shared centered table pattern
(cellpadding, bgcolor panel, h3 + aligned paragraphs) so GitHub renders
consistent spacing. Align labs and mlsysim DEV-BANNER with the same layout
and 2026 messaging.
Use a short top-of-README callout for periodic-table, StaffML, TinyTorch,
slides, and instructors: live with the 2026 release, expect steady iteration,
link to GitHub issues. Slides banner replaces dev-only wording with the same
framing while keeping dev/live badges.
* feat(footer): build-time "last updated" stamp
Add a small build-time stamp to the page footer ("Last updated YYYY-MM-DD
· <site> · <commit>") so readers can see at a glance that the site is
fresh. Quarto's per-page `date-modified` already exists for chapter
pages, but it doesn't capture site-level rebuilds (theme tweaks,
navbar changes, deploy reruns).
Pieces:
- shared/scripts/inject-build-stamp.sh: wraps a token-replace over a
build directory. Search-and-replace on `<!-- MLSB_BUILD_STAMP -->`
means sites that haven't adopted the token are unaffected — opt-in
rollout per subsite.
- book/quarto/config/shared/html/footer-common.yml: token added next
to the existing copyright line in the shared book footer.
- shared/config/footer-site.yml: token added next to the copyright
in the unified-site footer.
- shared/config/site-head.html: minimal CSS for `.mlsb-build-stamp`
(small, neutral, dark-mode aware).
- .github/workflows/kits-publish-live.yml: representative wiring —
runs the stamp step after build and before deploy. Other publish-
live workflows can adopt the step the same way as they roll
through release-prep validation.
* feat(navbar): expose paper.pdf for TinyTorch / MLSys·im / StaffML
Each of these subsites already builds a companion paper.tex in CI and
ships the PDF alongside the HTML site. Surface those papers in the
navbar dropdowns where readers actually look for them:
Build menu:
- TinyTorch → site
- TinyTorch Paper (file-pdf icon, opens in new tab)
→ /tinytorch/assets/downloads/TinyTorch-Paper.pdf
- MLSys·im → site
- MLSys·im Paper (file-pdf icon, opens in new tab)
→ /mlsysim/mlsysim-paper.pdf
Prepare menu (after a separator):
- StaffML Paper (file-pdf icon, opens in new tab)
→ /staffml/downloads/StaffML-Paper.pdf
Paper URLs are intentionally kept in lockstep with the build steps in
tinytorch-publish-live (assets/downloads/), mlsysim-publish-live
(site root), and staffml-publish-live (out/downloads/). If a build
path moves, both the workflow and this navbar entry need to move
together — there is no single source.
* feat(404): per-site 404 pages for slides / instructors / unified site
The book, kits, labs, mlsysim, and tinytorch subsites already have
flavored 404.qmd pages that route lost readers to the right
neighborhood. Add the missing three so every subsite under
mlsysbook.ai has a coherent recovery experience instead of falling
back to GitHub Pages' default white-page 404.
- slides/404.qmd — slide-deck flavored copy, pointers back to
the deck index, the volumes, and the hub.
- instructors/404.qmd — instructor-flavored copy, pointers to the
course map, slides, and both volumes.
- site/404.qmd — landing-page flavored copy, the most
ecosystem-wide nav (links to every subsite)
because this is the most common 404 source
for inbound links from the legacy single-
volume mlsysbook.ai.
StaffML already has its own React not-found.tsx so no work needed.
TinyTorch's legacy Sphinx 404.md is preserved for now (still wired on
the Sphinx site that hasn't migrated yet).
* ci(precommit): block subsite-mirror drift on shared assets
Add a pre-commit hook that runs `shared/scripts/sync-mirrors.sh --check`
on every commit. The hook fails if any of the per-subsite real-file
mirrors (subscribe-modal.js, theme SCSS partials, logo) has drifted
from its canonical source in `shared/`.
Why a guard, not just a sync: Quarto's resource-copy step preserves
symlinks instead of dereferencing them, so we have to keep real
copies. Without the guard, "I'll edit the canonical and forget to
re-sync" silently re-introduces the duplicate-divergence bug we just
spent effort fixing. `always_run: true` because a mirror can drift via
deletion of the canonical, not just by editing the canonical itself.
To re-sync after a deliberate change:
bash shared/scripts/sync-mirrors.sh
* refactor(audit): duplicate-file finder + clean up obvious leftover
Add shared/scripts/find-duplicates.py as a periodic duplication
auditor. It SHA-1 hashes every source-y file across the ecosystem
roots, groups identical contents, subtracts the intentional groups
declared in shared/scripts/sync-mirrors.sh, and reports the rest as
unintended duplicates. JSON report written to .audit/duplicates.json
for CI ingest later; --strict makes it exit non-zero.
Defaults err on the side of being useful out of the box:
- Skips symlinks (those are deliberate aliases, not duplicates).
- Skips small files (<256B) — LICENSE stubs, .gitkeep, etc.
- Skips _site / _build / node_modules / .next / out / .git.
- Source-y suffix list (.js, .ts, .scss, .css, .html, .yml, .py, .sh).
Binary assets (images, PDFs) are NOT scanned because their dup
story is different (logos, icons are intentionally repeated).
Initial-cleanup pass:
- Delete tinytorch/scripts/cleanup_repo_history.sh — byte-identical
leftover; the canonical version lives at
tinytorch/tools/maintenance/cleanup_history.sh and is the one
referenced by tinytorch/tools/maintenance/README.md.
After this commit the only remaining unintended duplicate is
runHistoryProvider.ts in three vscode-ext packages (kits / labs /
tinytorch). Promoting that into a shared vscode-ext package is real
refactor work — out of scope for release-prep, captured for later.
Add .audit/ and _audit/ (the latter from the Playwright site-audit
script) to .gitignore.
* docs(release-prep): handoff notes covering all five PR groupings
Add a single document at the worktree root that walks through what
this branch contains, why each piece is there, the recommended PR
split (PR-1 safety-net, PR-2 visual polish, PR-3 scripts/audits/
cleanup, PR-4 TinyTorch prep, PR-5 cutover skeletons), what was
intentionally LEFT OUT (and why), and what verification was done
locally vs. what still needs the dev mirror to exercise.
Treat this as the cover memo for the staged-rollout foundation
work; once the five PRs are individually merged into dev, this file
will outlive the branch but the per-PR sections still document why
each piece exists for anyone debugging months from now.
Audit of the eight sub-project READMEs showed inconsistent surrounding
text around the auto-managed contributor table — some had a Legend line,
some didn't; instructors used a different heading style; interviews was
missing the thanks blurb and CTA; mlsysim was missing the END marker
and the recognition CTA.
Standardize all eight to the same template: heading + thanks blurb +
legend + ALL-CONTRIBUTORS markers + Recognize-a-contributor CTA.
Per-project quirks preserved: interviews keeps its closing author
sign-off paragraph; CTA wording stays project-specific (e.g. labs
suggests "code, tutorial, test, or doc" while kits suggests
"tool, test, video, or doc").
Per-project sections kept (not consolidated into root). Sub-READMEs
are landing pages, sub-projects could be extracted to standalone repos
later, and recognition is more meaningful where the work lives. The
root README continues to aggregate everything via the existing
sectioned tables.
Closes the gap where Slides and Instructor Site were first-class Quarto
sites but invisible to the contributor recognition pipeline, and fixes
two pre-existing holes for mlsysim/interviews.
Workflows
- all-contributors-add.yml: add `slides` and `instructors` to PROJECTS;
add `slide`/`instructor` aliases. Tighten the LLM prompt with explicit
multi-type and emoji/punctuation rules, and add a deterministic regex
fallback that scans the trigger comment for type keywords and unions
them with the LLM result so a flaky classification never drops a tag.
- update-contributors.yml: add `mlsysim`, `interviews`, `slides`,
`instructors` to the push trigger paths and to the file/commit lists,
so edits to those configs actually rebuild and push READMEs.
Generators
- generate_main_readme.py: refactor the per-section block to a single
PROJECT_SECTIONS table so adding a project is one line; add Slides
and Instructor Site sections.
- generate_readme_tables.py: register `slides` and `instructors`.
Configs / READMEs
- New `slides/.all-contributorsrc` and `instructors/.all-contributorsrc`
seeded with profvjreddi.
- Add ALL-CONTRIBUTORS-LIST markers + recognize-a-contributor blurb to
`slides/README.md` and `instructors/README.md`.
- Regenerate root, slides, instructors, and (sorted-badge drift) the
interviews README via the generators.
Docs
- Refresh `.github/workflows/contributors/README.md` to list all 8
projects and document the canonical-list-in-PROJECTS contract.
- Replace inline Google Fonts <link> tags in all 8 site configs with
a single `- file: shared/config/site-head.html` reference, so fonts
(Inter 400-800, JetBrains Mono) and Font Awesome are inherited from

- Add missing Inter weight 800 (was only in site-head.html, not configs)
- Add carousel CSS + JS for MLSys·im landing page (arrows, dots, slides,
auto-rotation, keyboard nav) — fixes non-functional < > buttons
