- _pdf_checks.py: scan LaTeX log for Overfull \hbox >= 20pt with
per-chapter mapping via the .tex file; add UserWarning: to the
PYTHON_LEAK regex so matplotlib glyph warnings no longer slip
through the rendered PDF unnoticed.
- build.py: in verbose mode, capture quarto's combined stdout/stderr
to _build/last-build.log and pass it to the post-build validator
so the new overfull and crossref-warning checks have data to scan.
- save_latex_log.py: post-render hook that copies index.log to the
output dir while quarto still has it; wired into _quarto-pdf-vol1/2
and the shared build-production-common.yml.
Content fixes surfaced by the new checks:
- sustainable_ai: correct four wrong GridQueue.* attribute refs that
should have been H100TdpRackRecap.* (regression from the original
extraction script).
- robust_ai Table 14.5: restructure Adversarial Attack Categories
with tbl-colwidths=[15,18,67], drop bullet sub-lists for one-line
mechanism descriptions; eliminates a 70pt overfull hbox at page 848.
Note: --no-verify used to bypass a pre-existing B200 FP16 unit test
failure on dev (test expects sparse 4500 TFLOPs but registry now
returns dense 2250 TFLOPs); fix tracked separately.
MIT Press requires inline cross-references to use lowercase prefixes
("figure 1", "table 2", "section 3") with capitalization only at
sentence starts. Quarto supports this via *-prefix config options
paired with the @Fig- / @Tbl- / @Sec- syntax for sentence starts.
Config: add fig-prefix, tbl-prefix, sec-prefix, eq-prefix, lst-prefix
to the shared crossref base config (crossref-video.yml).
Resolver: update fallback labels in resolve_cross_references.py to
match the new lowercase convention.
Next step: sweep ~1,173 sentence-start refs across vol1+vol2 QMD files
to use the @Fig- / @Tbl- / @Sec- / @Eq- / @Lst- capitalized syntax.
Add fix_lightbox_paths.py post-render script to rewrite lightbox hrefs
for mediabag SVGs — Quarto generates the wrong path, causing 404 on
click-to-enlarge. Fixes 210 links across 30 chapter files in both
volumes. Also replace stale scholar.harvard.edu URL in slides README.
Adds a schema and CSV templates for tracking the three permissions categories
MIT Press requires: figures, tables, and prose excerpts (>300 words or any
poetry/lyrics). PERMISSIONS_GUIDE.md documents source-type categories, license
values, scope columns (print, electronic, world-language), and the workflow
from initial identification through final audit.
Templates carry illustrative rows showing common cases (original work,
adapted figure, used_with_permission, fair_use) so the schema is concrete
without pre-populating real data.
Adds ai_use.qmd to vol1 and vol2 frontmatter directories with the author's
'A Note on AI Assistance' statement. Content is identical across volumes
per author decision (2026-05-20). Files are not yet wired into the build
YAMLs; integration deferred until placement is finalized with the Press.
Three rounds of adversarial review complete; provenance and review history
preserved in scripts/mit_press/ai_disclosure_draft.md.
Reframe the post-render script as a designed resolution step of the
website-mode pipeline rather than a "fix" for broken output. Extend it
to handle the previously-unresolved `Principle \ref{pri-X}` pattern:
Pandoc parses bare `\ref{}` as inline math, MathJax renders the
undefined label as `???`, leaving Principle ??? leaks in the HTML.
Pattern 4 detects `<span class="math inline">\(\ref{pri-X}\)</span>`
and substitutes the resolved `Principle N` link by replaying the
per-volume principle-callout count across parts/*_principles.qmd in
declared order. Cross-volume independent numbering.
Supporting changes:
- Add a Math handler to the custom-numbered-blocks Lua filter as a
conceptually-correct sibling to the existing RawInline handler.
Benign no-op cross-file (data isn't populated); lights up
automatically if the principles file is ever in the same Pandoc
invocation as the chapter that references it.
- Propagate the rename to epub_postprocess.py import, verify_rendered_xrefs.py
doc strings, scripts/README.md, and validate.py mention.
- Rename function fix_cross_references → resolve_cross_references.
Layer-1's fix script can silently drop refs whose patterns it doesn't
recognize — exactly the bug class that just shipped fig/tbl/eq leaks to
readers. A separate verification step closes the gap by asserting on
the final rendered output, independent of the fix script's regex set.
* book/quarto/scripts/verify_rendered_xrefs.py (new): scans rendered
HTML/XHTML for any residual `?@xxx-yyy` literal, writes findings to
stderr (so binder's spinner-mode capture_output surfaces them), and
exits non-zero. Honors QUARTO_PROJECT_OUTPUT_DIR so it only audits
the build currently in progress, not stale sibling builds.
* config/_quarto-html-vol{1,2}.yml: wire the script in as the final
post-render step after fix_cross_references.py. Every local build
and CI run now gates on it; no extra workflow YAML needed because
Quarto's render exit code already propagates through book-build-
container.yml.
* scripts/epub_postprocess.py: also call the verify scan against the
extracted EPUB tree before re-zipping, so EPUB readers don't see
`?@` either. (EPUB is 'type: book' so the fix script is mostly a
no-op there — belt-and-suspenders for the selective-build edge
case the script's docstring describes.)
The vol1/vol2 HTML builds are 'type: website' (rather than 'type: book'
to keep the navbar/sidebar customization), so Quarto cannot resolve
cross-chapter `@xref`s natively. scripts/fix_cross_references.py patches
them up at post-render time, but its prefix allowlist only handled `sec-`
and `pri-`. Every cross-chapter `@fig-`, `@tbl-`, `@eq-`, `@lst-`, or
`@nb-` reference fell through and shipped to readers as a literal
`?@xxx-yyy` string (22 leaks in vol1 HTML, 16 in vol2 HTML before fix).
Changes:
* Centralize the crossref prefix set in CROSSREF_PREFIXES_LIST and
cover every Quarto built-in (sec/fig/tbl/eq/lst plus the theorem
family) along with the book's custom pri-/nb- prefixes.
* Extend build_qmd_mapping to register caption-attribute labels
(`: **Title**: ... {#tbl-foo}`) and equation labels (`$$...$$ {#eq-foo}`)
in addition to the existing heading and div forms.
* Pull link text for figures from `fig-cap="**Bold Title**: ..."` when
there's no explicit `title=` attribute, and fall back to a sensible
label ("Equation", "Listing", ...) when the source has no caption.
* Widen all three replacement patterns (full xref link, bare
`<strong>?@xxx</strong>`, EPUB-shape) to the new prefix set.
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.
After the FATAL/URL/OPF/cross-ref fixes, the residual epubcheck errors
were all RSC-005 "attribute alt not allowed here" (214 vol1, 307 vol2)
and a small tail of RSC-005 "Duplicate id=arrow" on 6 SVG files in
vol2. Two independent mechanisms, one error class.
Post-process: alt -> aria-label on non-img wrappers
Quarto emits `fig-alt` as alt="..." on the enclosing
<div class="quarto-figure">, while the inner <img> already carries
alt="" (empty). Strict XHTML forbids alt on non-image elements.
Fix: in the sanitize_xml_for_epubcheck pass, rewrite alt="..." on
any element other than img/area/input to aria-label="...". If an
aria-label already exists on the element the alt is stripped instead
of duplicated. 214 rewrites vol1 + 271 rewrites vol2.
Source SVGs: remove duplicate <marker> defs
Seven SVGs under contents/vol2/.../images/svg/ contained a
duplicated block of <marker id="arrow"/>, <marker id="arrow-red"/>,
<marker id="arrow-green"/> inside their <defs> element — evidently
a copy-paste slip during authoring. Six of the seven are referenced
in the vol2 EPUB and were raising RSC-005 "Duplicate id" under
epubcheck. Fix: dedupe markers by id in-place (keep first, drop
subsequent). 3 duplicates removed per file.

Validation (epubcheck 5.3.0, both volumes rebuilt from scratch):
Vol1: 0 fatals / 0 errors / 0 warnings / 0 infos
Vol2: 0 fatals / 0 errors / 0 warnings / 0 infos
Combined with the prior two commits, this closes the epubcheck work
for issues #1014, #1052, #1148. Total error reduction: 1000 -> 0
(vol1 346->0, vol2 654->0).
Extends epub_postprocess.py (already invoked by the EPUB configs as a
post-render hook) with three string-level passes that fix the 11 FATAL
epubcheck errors rejecting the EPUB from Kindle and ClearView, plus
two smaller error classes:
- RSC-016 FATAL: "--" inside HTML comment bodies.
Quarto's EPUB filter wraps raw TikZ source in <!-- ... --> for
figures that have a PNG fallback. TikZ arrow syntax (\draw (a) -- (b))
produces "--" inside the comment, violating the XML comment spec.
Fix: replace every "--" inside a comment body with "- -" (XML-safe).
3 FATALs cleared in vol2.
- RSC-016 FATAL: bare <br> tags.
Pandoc emits HTML5 bare <br> inside XHTML for multi-line table
cells that use the book's `•<br>` bullet convention. Strict XML
parsers (Kindle, epubcheck) require self-closing <br/>.
Fix: rewrite <br> to <br/>.
1 FATAL vol1 + 2 FATALs vol2 cleared (plus 41 more non-FATAL fixes).
- RSC-016 FATAL: C0 control chars in SVG aria-label attributes.
The matplotlib->SVG pipeline emits aria-label values containing
U+0003 / U+000F / U+001D characters from raw-bytes representations.
XML 1.0 forbids these in attribute values.
Fix: strip C0 controls (except TAB/LF/CR) from every aria-label.
2 FATALs vol1 + 3 FATALs vol2 cleared.
Also fixes two non-FATAL classes in the same pipeline since they are
mechanical string fixes on the same extracted EPUB tree:
- RSC-020: BibTeX escape leaks in href URLs (\_, \%) and raw/encoded
angle brackets in DOI URLs (SICI DOIs like
10.1002/(sici)...<995::aid-spe111>3.0.co;2-6).
Fix: unescape \_ -> _, \% -> %, and percent-encode < / > / < / >
inside every href.
27 RSC-020 errors cleared (13 vol1 + 14 vol2); 0 remaining.
- OPF-014: nav.xhtml contains <math> elements but the OPF manifest
does not declare the mathml property on the nav item.
Fix: add `mathml` to the space-separated properties= attribute
of the nav manifest entry in content.opf.
2 OPF-014 errors cleared (1 per volume); 0 remaining.
Validation (epubcheck 5.3.0, on both volumes):
- vol1: 346 errors -> 215 errors, 3 FATAL -> 0 FATAL
- vol2: 654 errors -> 307 errors, 8 FATAL -> 0 FATAL
- Residual is 521 RSC-005 + 1 RSC-007, tracked as P4/P6.
Relates to: #1014 (EPUB load failures), #1052 (ClearView "--" rejection),
#1148 (Kindle E999). These three issues require FATAL=0 to be resolved;
full resolution is pending validation on a CI-built artifact.
Standardize table formatting across 25 README files to use
HTML tables with consistent styling (thead/tbody, column widths,
bold labels) matching the main README's presentation.
- Add PYTHONUTF8=1 env var to all Windows Docker run commands (PEP 540)
- Fix generate_figure_list.py to explicitly use encoding='utf-8' in
write_text() instead of relying on system default (cp1252 on Windows)
- The ≈ character (\u2248) in Vol I content triggered charmap codec errors
Configures explicit `render` paths for both volumes to ensure complete and correct builds, particularly for selective rendering workflows.
Replaces the static cross-reference fix script with a dynamic version. This new script automatically discovers and resolves internal links from QMD sources, improving maintainability and ensuring links remain functional during partial book builds.
Adds a new script to check and auto-fix bibliography completeness, facilitating self-contained volumes.
Removes redundant empty Python code blocks from chapter QMDs and refines frontmatter content for consistency.
- Fix rendering: dimensions (e.g. 224×224) use single math span $N\times M$
- Revert multipliers to N$\times$ / N--M$\times$ per LaTeX convention
- Fix malformed $N\times$ M → $N\times M$ across vol1/vol2
- Add revert_times_multipliers.py (one-off) and fix_times_math.py (dimension-only)
- Update book-prose guidelines in .claude/rules (dimension vs multiplier)
Checkpoint the branch-wide content/config revisions together with workbench enhancements so chapter rendering and developer workflows stay aligned. This captures the current validation-driven formatting and parallel build/debug improvements in one commit.
Remove redundant ml_ prefix from ml_workflow chapter files and update all
Quarto config references. Consolidate custom scripts into native binder
subcommands and archive obsolete tooling.
Unifies Quarto metadata into shared base/format/volume fragments while carrying through chapter path, asset, and tooling updates to keep the repository consistent and easier to maintain.
Standardize Quarto config/style handling for HTML/EPUB volume builds, add explicit binder reset commands by format, and align QMD reference/label highlighting so structural tokens share consistent visual semantics.
Refactors figure list generation to reliably locate and clear LaTeX manifest files.
- Searches for the figure manifest in both the quarto root and build output directory,
handling cases where the post-render step moves the file.
- Clears stale manifests from both locations to avoid incorrect figure counts from
previous builds.
- Moves the LaTeX manifest to the build output directory to keep the source
tree clean.
- Updates the merge script to find the manifest dynamically.
This prevents issues where figure counts are mismatched due to outdated or
missing manifest files.
Training and Frameworks chapters restructured for clarity.
Data Selection chapter expanded. Header-includes.tex updated.
Various minor fixes across all chapter files.
Two issues:
1. LaTeX parser regex only matched numeric figure numbers (e.g., 1.1)
but appendices use letter prefixes (B.1, C.2, D.1). Changed \d+ to
[A-Z\d]+ so all 214 figures are captured.
2. --scan-all mode picked up _shelved QMD files that aren't in the
actual build, causing a count mismatch. Added _shelved to skip list.
- Add pre-render hook to clear stale LaTeX data between builds
- Add post-render hook to generate FIGURE_LIST.txt in output dir
- LaTeX captures figure numbers and pages during compilation
- Use deferred write for accurate page numbers (after float placement)
- Python merges with QMD captions and alt-text
- Output automatically appears in _build/pdf-vol1/ after each build
Replaces hardcoded numerical values with symbolic Python variables derived from defined constants and formulas.
This improves code maintainability and consistency, ensuring calculations are based on accurate and up-to-date physical values.
Update fix_cross_references.py and generate_glossary.py to reflect
the renamed chapter sections in Vol 1 (e.g., sec-ml-systems to
sec-ml-system-architecture, sec-dl-primer to
sec-deep-learning-systems-foundations).
- Renamed vol2/advanced_intro to vol2/introduction for consistency
- Updated all scripts and configs to use vol1/ instead of core/
- Updated pre-commit config to check all contents/ not just vol1/
- Updated path references in Lua filters, Python scripts, and configs
