Keep fail-fast installation checks for Ghostscript command presence, but defer executing Ghostscript until the final verification phase where full runtime dependencies and PATH are in place.
Add immediate per-tool post-install checks with explicit command resolution and exit handling, keep end-of-job final verification with isolated per-tool reporting, and ensure rsvg-convert is installed/verified for Quarto PDF SVG conversion.
- Add explicit ENV PATH directive (Phase 15) so Docker layers
inherit tool paths instead of relying on registry writes
- Reorder phases: TeX Live moved last (slowest, fail last)
- Create stable symlink C:\texlive\bin\windows for year-agnostic PATH
- Skip pip self-upgrade to avoid WinError 3 shim lock
- Use gswin64c (correct Scoop binary name) instead of gs
- Add rsvg-convert fallback to Chocolatey if Scoop fails
- Replace fragile verification loop with Test-Tool function
- Relax ErrorActionPreference for Chocolatey TeX Live in baremetal
- Baremetal workflow: verification step now tracks failures and exits
non-zero when tools are missing (previously always reported success)
- Baremetal workflow: R.exe --version replaced with Rscript --version
to avoid PowerShell Invoke-History alias collision
- Windows Dockerfile: Quarto install switched from direct zip download
(C:\quarto-1.9.27\bin) to scoop install extras/quarto for consistent
PATH handling via Scoop shims
- Windows Dockerfile: final verification rewritten with failure tracking
and exit 1 on missing tools
Introduces Windows HTML, PDF, and EPUB build configurations for both Volume I and Volume II in the GitHub Actions workflow, expanding the available output formats for the book.
Updates Quarto callout and figure syntax from `::::` to `:::` across numerous content files for consistency and compatibility.
Removes unreferenced `war_stories.bib` and `data_engineering.bib` bibliography files and their corresponding entries in Quarto configuration.
Standardizes internal references to the 'Responsible AI' chapter by updating `@sec-responsible-engineering` to `@sec-responsible-ai` for improved linking accuracy throughout the text.
The CI workflow hard-pinned black==24.10.0 separately from requirements.txt
(which said >=23.0.0), causing version skew that reformatted 11 QMD files
on every CI run. Remove the override and let requirements.txt be the single
source of truth, bumped to >=24.0.0 to align with current latest.
Pin Black in the dev validation workflow so book-format-python produces deterministic output across local and CI environments, preventing first-pass auto-format churn from failing pre-commit.
Updates the book publishing workflow to conditionally verify downloaded artifacts based on the `deploy_target` input, preventing failures during partial deployments.
Explicitly sets the output filenames for EPUB and PDF builds in Quarto configurations, ensuring consistent naming for generated book artifacts.
- Quarto 1.9.27: Linux (.deb), Windows (direct download; Scoop Extras has 1.8.27)
- R 4.5.2: Linux (CRAN jammy-cran40), Windows (Scoop main/r)
- Baremetal: quarto-actions/setup for both Linux and Windows
- Remove ggrepel version pin (R 4.5.x supports ggrepel 0.9.7)
- Update docs: BUILD.md, CONTAINER_BUILDS.md, docker READMEs
Include pandas in validate-dev fallback dependencies to satisfy mlsysim.sim imports during book-mlsys-test-units when base requirements install partially fails.
Add fallback hook dependencies in validate-dev and apply trailing-whitespace fixes to lab plan files so pre-commit no longer fails on auto-modifications.
Switch container/baremetal/validate/preview/live flows to vol1+vol2 artifacts, keep baremetal in dev validation, and add stable single-book navbar link.
Allows a single `@all-contributors` comment to add or update a contributor across multiple projects simultaneously.
Updates the workflow to:
- Detect multiple projects from explicit mentions in the trigger comment.
- Iterate over all detected projects to update their respective `.all-contributorsrc` files and project `README.md` tables.
- Adapt commit messages and bot replies to reflect multi-project changes.
This improves efficiency for managing contributors in multi-project repositories by reducing repetitive commands.
- Add -v2 to cache key to invalidate stale R package cache
- Add ggrepel to verification step to catch missing packages early
- Fixes hw_acceleration.qmd build failure (fig-processor-trends chunk)
- Add git pull --rebase before push so concurrent comment-triggered runs
don't reject each other (only one of three runs had succeeded for PR 1179).
- Manually add @salmanmkc as code contributor to tinytorch and kits
(labs was already added by the single successful run).
The LLM (llama3.1:8b) was hallucinating usernames — e.g. returning
"pipmea" instead of "pipme". Since the username is always present as
an @mention in the trigger line, extract it deterministically via regex
in Step 1 and only use the LLM to classify contribution types.
Display version number and release date (e.g., "v0.1.8 · Feb 7, 2026")
next to the "Under Construction" badge in the top nav bar. Version and
date are declared as top-of-file constants in wip-banner.js for easy
CI sed updates. Publish workflow now bumps 6 files instead of 5.
Add generate_team.py script that reads .all-contributorsrc and generates
the team.md page automatically. This keeps the website team page in sync
with the README contributors.
- Add tinytorch/site/scripts/generate_team.py
- Update both deploy workflows to run the script before building
- Contributors added via @all-contributors now appear on the website
The script runs during site build, so team.md stays fresh with each deploy.
Slides were not loading on the live site because the PDFs exist in a
GitHub Release (tinytorch-slides-v0.1.0) but were never downloaded
during the build process. The .gitignore has *.pdf which prevents
slides from being committed to git.
Add a step to both deployment workflows to download all slide PDFs
from the release and inject them into _static/slides/ before deploy.

On PR events, github.ref_name resolves to the merge ref (e.g.
"1159/merge") which doesn't exist on raw.githubusercontent.com,
causing a 404. Use github.head_ref (the actual source branch)
for PRs, falling back to ref_name for push events.
Also adds -f flag to curl so HTTP errors fail immediately with
a clear message instead of silently saving the 404 HTML page.
LLM now only parses username + contribution types (strict 2-field JSON).
Project detection is fully deterministic from file paths:
tinytorch/ → tinytorch, book/ → book, kits/ → kits, labs/ → labs
If project cannot be determined, the bot asks the user instead of
silently defaulting to book. Also removes @AndreaMattiaGaravagno
from book/.all-contributorsrc (was incorrectly added there by the
old workflow — their PR only touched tinytorch/ files).
Fork PRs downgrade GITHUB_TOKEN to read-only, causing 403 when
applying labels. pull_request_target runs in the base repo context
and grants the declared write permissions.
Instead of a separate workflow, adds a 'site_only' boolean checkbox
to the existing Publish (Live) workflow. When checked:
- Skips version bump (pyproject.toml, badges, installer, announcement)
- Skips PDF generation
- Skips tag creation and GitHub Release
The build & deploy steps still run identically. One workflow, two modes.
Removes the previously added tinytorch-deploy-site-only.yml.
Adds a new workflow 'TinyTorch · 🌐 Deploy Site Only' for deploying
website content updates without triggering version bumps, tags, or
releases. Ideal for:
- Typo fixes
- Team page updates
- CSS/styling changes
- Documentation updates
Use 'Publish (Live)' for versioned releases, 'Deploy Site Only' for
quick website-only updates.
- Default test_type: quick → all (run full validation by default)
- Default os: linux → all (test both platforms by default)
- Rename 'release' → 'user-journey' to match CLI --user-journey flag
- Fix 'standard' to correctly stop at stage 5 (was running user-journey)
- Reorder options to show defaults first in dropdown
- Change Validate (Dev) icon from 💯 to ✅ for Book and TinyTorch
- Change Update PDFs icon from 📄 to 📑 (bookmark tabs)
- Fix workflow_run references to match exact workflow names
This makes it easier to visually distinguish between Validate and
Publish operations in the GitHub Actions UI.
Bug Fix:
- Export failures now return early in module complete, preventing
progress from being updated when export fails. This fixes the issue
where students could start Module 02 even though tensor.py was
never exported.
New --user-journey test:
- Simulates exact student flow: module start --no-jupyter → module complete
- Runs milestones at natural unlock checkpoints (not all at end)
- Milestone checkpoints: after modules 03, 08, 09, 13, 19
- Explicit step-by-step output for easy CI debugging
New --no-jupyter flag:
- Added to 'tito module start' for CI/testing
- Creates notebook but skips opening Jupyter
