The new models ("standard_v2_x" and "standard_v3_0") supports 200+ content types: https://github.com/google/magika/tree/main/assets/models/standard_v3_0/README.md

Ideally, we have at least one "basic sample" for each of the supported content types (See /tests_data/basic/*).

This issue acts as a call for action -- external help is very welcome!

Important aspects to keep in mind:

• Content types for which we have no samples yet should be prioritized. Among these, prioritize more common content types rather than niche ones.
• The "basic" test samples (in the tests_data/basic/<content_type>/*) are supposed to be "easy to recognize". In other words, the goal for these samples is to check that the model does a reasonable job with clear-cut samples, rather than corner-cases.
• It's OK to group a bunch of test cases in a single PR.
• The PR should state the origin of each sample.
• The samples should NOT be taken from existing projects / online resources (in these settings, it would be very challenging to properly document the origin of these files); they should be manually written/created by the PR author.
