 # DESCRIPTION--------------------------------------------------------------------------
   # This configuration defines three main CI trigger patterns:
     # 1. Pull Request Validation: Validation performed on PR basis
+      # - we have mandatory minimal checks that run on all PRs (even if only docs are changed)
+      # - we have more extensive pr_code_changes_checks that run if code is changed
     # 2. Nightly Development: Test set run nightly (validates most important test cases)
     # 3. Weekly Full Validation: Test set run weekly (validates all test cases to prevent any surprises)
   # Each pattern represents different balance between validation depth, execution time and CI resource usage
 
 # TRIGGER PATTERNS-------------------------------------------------------------------

-  # This test validates Standards, Package tests, Project tests and Desktop standalone tests to ensure that main platforms are covered

+    # 1) PR changes code in com.unity.netcode.gameobjects package (Editor, Runtime or Tests folders) or in testproject folder or package.json file

 # Run all relevant tasks when a pull request targeting the develop or release branch is created or updated.
 # In order to have better coverage we run desktop standalone tests with different configurations which allows to mostly cover for different platforms, scripting backends and editor versions.
 # This job will FIRST run "run_quick_checks" jobs (defined in _run-all.yml) since it's the dependency of project pack jobs which is on the lowest dependency tier. This runs the fastest checks (like PVP or code standards) and ONLY IF those pass it will run the rest of the tests.
 # This optimization allows to speed up feedback look for any "obvious" errors and save resources.
 # Since standards job is a part of initial checks it's not present as direct dependency here!!!!!!!!!!!!!!!!!!!!
