"""Static validation for the activeblue_familylaw Odoo 18 module.

Not a substitute for running the Odoo test suite — it catches the classes of error
that are cheap to find without a running Odoo/DB:

  * Python files compile
  * XML files are well-formed
  * no Odoo-18-forbidden constructs in views (attrs=, states=, <tree>)
  * every type="object" button name maps to a real method in the model layer
  * every file listed in __manifest__["data"] exists
  * ir.model.access.csv references models that are defined

Run: python3 scripts/validate_module.py
