Add pdfmanagement-testphase to TinyTeX bundle

[gordonwoodhull]

Hi @cderv,

I noticed that pdf-standard tests were taking a long time and timing out.

It's due to indirectly required package pdfmanagement-testphase.

So I asked DeepWiki how to add another package to tinytex.

Summary

• Add pdfmanagement-testphase to tools/pkgs-yihui.txt

The latex-lab package (added in 16ccf03) provides \DocumentMetadata support for PDF/A and PDF/UA standards. However, latex-lab loads pdfmanagement-testphase at runtime, and this package is not declared as a TeX Live dependency of latex-lab, so it doesn't get pulled in automatically when the TinyTeX bundle is built.

This causes a slow auto-install (~10+ minutes on Windows) the first time a PDF/A document is compiled with TinyTeX, because tlmgr needs to update itself and then search for and install the missing package. We noticed this causing consistent CI timeouts in Quarto's test suite on Windows (example).

Process followed

Per DeepWiki guidance for adding a package to the TinyTeX bundle:

1. Added pdfmanagement-testphase to tools/pkgs-yihui.txt in alphabetical order
2. tools/sort.R can be run to verify alphabetical order and deduplicate against pkgs-custom.txt
3. tools/test-packages.R is the full validation script (compiles test documents and verifies packages) — CI workflow .github/workflows/required-latex-pkgs.yaml should run this automatically

Test plan

• CI workflow verifies package list
• Confirm pdfmanagement-testphase is not already in pkgs-custom.txt (verified: it is not)
• Confirm alphabetical ordering is correct (between pdfpages and pdfsync)

Why pdfmanagement-testphase is still needed as a separate package

I (Claude) investigated why this package still has "testphase" in its name given that \DocumentMetadata is fully baked into the LaTeX kernel as of 2023+.

Per CTAN and the latex3/pdfresources repo, the LaTeX Project has been planning to merge this into the kernel since 2021, but as of version 0.96y (2026-01-23) that still hasn't happened. The README says:

"The code is currently provided as independent package. At a later stage it will be integrated into the LaTeX kernel (or in parts into permanent support packages)."

The dependency chain is:

1. \DocumentMetadata{} — kernel command (production since LaTeX 2023)
2. → loads support files from latex-lab (already in pkgs-yihui.txt)
3. → which loads pdfmanagement-testphase for the actual PDF management (dictionaries, annotations, PDF standards, embedded files)

So it's production-required code with a historical "testphase" name, and TeX Live doesn't declare it as a formal package dependency of latex-lab, which is why it needs to be listed explicitly.

All good. I understand why this is needed.

@yihui I let you merge - We never discussed it so I want to verify if you prefer to clean the commit message from Antrophic Claude attribution in this repo. Thanks.

That's okay to me. It will be nice if we could know in the future when this "testphase" package is no longer needed so we can remove it from the list accordingly (I'm not sure if we can tell it from our current GHA checks).

Thanks!
