Remove all font processing in this PDF customomization. Leave the font files where they are.

**Adjusting PDF Customization**

I'm planning to modify PDF files by removing all font processing while leaving the font files intact. The workspace includes several relevant files, such as fop.xconf and custom XSL templates. I need to follow instructions carefully and start by inspecting these files. It looks like we might need to update the configurations in fop.xconf to disable font processing and remove any templates that reference fonts. I'll take a closer look to ensure accuracy without deleting necessary files. Let's inspect the relevant files now.

**Explaining font warnings**

The user is getting warnings related to missing font definitions for logical names like 'serif', 'sans-serif', and 'monospace'. This happens because they neutralized font mappings and disabled auto-detect. Since XSL references logical names in the output, FOP can't find corresponding physical fonts and issues warnings. To resolve this, they could re-enable auto-detect, restore mappings, change their XSL, or set a generic font family. However, they aimed to silence warnings while keeping the font files. It’s a bit tricky!

let's auto-detect

**Planning tool calls and updates**

I need to send a brief preamble to the user before making tool calls. The guidelines say to explain what I’m about to do. So I’ll say, “I’ll re-enable FOP auto-detect in `cfg/fop.xconf` to restore font registration.” Then, I’ll update the todo list to reflect this task. I’ll need to use the manage_todo_list tool to mark it as in-progress and ensure I provide the full list of items, which includes completed tasks.

still getting the error

---

_**Agent (copilot/claude-sonnet-4.6)**_

The user is still getting PDFX008W errors about font definitions not found. Let me think about this more carefully.

The PDFX008W error is from DITA-OT's PDF2 plugin (not FOP directly). It's DITA-OT's i18n font resolution system that reads `fo/font-mappings.xml` to map logical font names to physical font faces. 

We emptied `fo/font-mappings.xml` to just `<font-table/>`, which means the DITA-OT i18n processor can't find mappings for `serif`, `sans-serif`, `monospace` etc.


The issue is that we need to restore the standard CSS-to-logical font aliases in `font-mappings.xml` so DITA-OT can resolve generic font names like `serif` to its internal logical fonts like `Serif`. We also need the corresponding logical font definitions pointing to standard system fonts, otherwise the i18n processor will still fail to resolve them.

I'm realizing that when we provide a custom `font-mappings.xml`, it completely replaces the base plugin's version rather than merging with it. So the simplest approach is either to delete the custom file entirely so DITA-OT falls back to its defaults, or restore just the standard aliases and logical font mappings without the custom Calibri/Fira Sans entries. Let me check the `catalog.xml` to see if it's explicitly referencing the custom font-mappings file.

now let's default to using Calibri as the base font, fallback is Sans

---

_**Agent (copilot/claude-sonnet-4.6)**_

The user wants to set Calibri as the base font with Sans as fallback. This means:

1. In `fo/font-mappings.xml` - map the logical fonts to use Calibri as the primary font face, with Sans/Helvetica as fallback
2. In `fo/attrs/custom.xsl` - we removed all the `font-family` attributes earlier. We need to add back the `__fo__root` attribute set with `font-family` set to the appropriate logical name that maps to Calibri.

Since FOP uses `auto-detect` to find system fonts, Calibri should be available (it's a Windows system font). 

So I need to update the font mappings to point the logical font names to Calibri, then reference that logical name in the root attribute set. FOP's auto-detect will handle finding the actual system font. The real solution is to set `font-family` in `custom.xsl` to something like `"Calibri, sans-serif"` so FOP can fall back gracefully if Calibri isn't available, rather than trying to handle fallbacks purely through the font-mappings configuration. Updating font mappings and custom attributes...

I'm realizing that XSL-FO supports comma-separated font families just like CSS, so I can specify `Calibri, sans-serif` directly in the font-family attribute to let FOP try Calibri first and fall back to the generic sans-serif. The key is understanding how DITA-OT's font-mappings preprocessor works alongside the actual FO rendering—I need to decide whether to use logical names from font-mappings or direct font names in the rendered output. The cleanest solution is probably to keep the logical name mapping in font-mappings.xml while ensuring the FO attributes reference those names
