This pull request adds a new set of internal guidance documents that make Odoo’s development, review, web, and security expectations easier to find and apply. By documenting rules that were previously informal, it helps new contributors and automation tools produce more consistent, safer code.

Before this commit, the JS conventions of the framework only existed in review comments and in the heads of the people enforcing them. Nothing in the repository stated them, so a new developer, or a coding agent, had no way to find them.
