 3. **Backend OWL**: Use standalone `rpc()` from `@web/core/network/rpc`. NOT `useService("rpc")`. `static props = []` not `{}`.
 4. **HTTP routes**: `type="jsonrpc"` — NOT `type="json"` (deprecated).
 5. **res.config.settings**: Only boolean/integer/float/char/selection/many2one/datetime. NO Date fields.
+   **`config_parameter=` Boolean fields don't round-trip `False` as a string.** Odoo's `set_values()` calls `IrConfigParameter.set_param(key, value)`, and `set_param` deletes the row when `value` is falsy (False / None / empty). So writing `False` to a Boolean config field means the param no longer exists in `ir_config_parameter`; a subsequent `get_param(key)` returns the *default* (Python `False`), not `'False'`. Test like `self.assertFalse(ICP.get_param('...'))` — never `assertEqual(..., 'False')`. (Integer/Float/Char go through `repr(value)` / strip, so they DO persist as strings — `'90'`, `'0'`, etc.) Source: `odoo/addons/base/models/res_config.py::set_values` and `ir_config_parameter.py::set_param`.
 6. **res.groups**: NO `users` field, NO `category_id` field.
    **res.users**: field was renamed `groups_id` → `group_ids` (also `all_group_ids` for implied). The plural form is gone; using `groups_id` raises `ValueError: Invalid field 'groups_id' in 'res.users'`.
    **`ir.ui.view`**: same rename — view-level visibility gating uses `group_ids`, not `groups_id`. A record like `<field name="groups_id" eval="[(4, ref('base.group_system'))]"/>` on an `ir.ui.view` raises `ValueError: Invalid field 'groups_id' in 'ir.ui.view'` at module install. (The XML *attribute* `groups="base.group_system"` on form elements like `<page>`, `<button>`, `<field>` is unrelated and still works.)
