How to access the title in postprocessors and in the directory config?

[c33s]

i am trying two things:

1. put the downloaded files in a folder structure with the current date, the category (site) and the title.

...
    "extractor": {
        "directory": ["{now:%Y-%m-%d}", "{'uncategorized'|category}", "{'untitled'|title}"],
    },
...

this config always leads to 2023-02-22/uncategorized/untitled even if the dumped metadata json files contain all the required data (title and category).
i don't understand why this is not working. if i remove the directory extractor from the config i get the default directory name which correctly contains the title.

2. create a pdf with the postprocessors.

...
    "extractor": {
        "postprocessors": [
            {
                "name": "exec",
                "command": "cd {} && convert *.jpg doc.pdf",
                "#command": ["convert", "{_directory}*.jpg", "{_directory}{_filename}.pdf"],
                "async": false,
                "event": "finalize",
            },
            {
                "name": "exec",
                "command": ["cp", "{_directory}doc.pdf", "{_directory}{uncategorized|category|title}.pdf" ],
                "async": false,
                "event": "finalize",
            }
        ],
    },
...

my first problem is that i can only choose between string command without the replacement patterns but with the possibility to use && to combine commands or the array command which has some replacement patterns but no && function. because of this limitation (or wrong usage of this tool by me) i split the process in two execs on finalize (one string to convert to a hardcoded name and one array which copies the hardcoded name to the title)

i am trying to create a pdf with all images with the directory name or the title but there is no "parent dir" replacement pattern and the {uncategorized|category|title} sadly has only the category set.
what am i doing wrong? why is the title not set? how to access the title in finalize? can i somehow concat commands with the array structure?

{'uncategorized'|category}", "{'untitled'|title}"

Alternatives are applied from left-to-right, so it should be
{category|'uncategorized'}", "{title|'untitled'}"
(read it as "use {category} if it has a value, otherwise 'uncategorized')

The idea is to call your own script with the right arguments, but I guess that doesn't really work on Windows. Using multiple exec post processors is a nice workaround.
