 11. **Inherited `ir.ui.view` records cannot have `groups`/`group_ids` on the record itself.** Odoo 19 raises `ParseError: Inherited view cannot have 'groups' defined on the record. Use 'groups' attributes inside the view definition` at install time. Move the gate to the inner XML nodes — every `<button>`, `<page>`, `<field>`, `<xpath>`, `<group>` etc. supports a `groups="base.group_system"` attribute. For an inherited form with a smart button + admin tab, put `groups=` on the button and the page individually; leave the `<record model="ir.ui.view">` clean.
 12. **`mail.template` QWeb/inline_template `ctx` IS `self.env.context`** — not a nested dict you can pass. `MailRenderMixin._render_eval_context()` sets `ctx = self.env.context`, so `ctx.get('foo')` in subject/body resolves to `env.context.get('foo')`. To pass dynamic data to a template, spread keys directly into the context: `tmpl.with_context(**my_data).send_mail(res_id, ...)`. Calling `tmpl.with_context(ctx=my_data)` puts the dict at `env.context['ctx']`, and the template's `ctx.get('foo')` becomes `env.context.get('foo')` → `None` (looks like a silent rendering bug — subject ends up blank).
 13. **`ir.cron` dropped `numbercall`** in Odoo 19. Old recipes set `<field name="numbercall">-1</field>` for "run forever"; that now raises `ValueError: Invalid field 'numbercall' in 'ir.cron'` at install time. Just omit the field — recurring crons keep running as long as `active=True`. Source: `odoo/addons/base/models/ir_cron.py` field list.
+14. **`cr.commit()` / `cr.rollback()` raise AssertionError inside `TransactionCase`** — they are NOT silent no-ops in Odoo 19. The test cursor explicitly refuses both ("Cannot commit or rollback a cursor from inside a test, this will lead to a broken cursor when trying to rollback the test. Please rollback to a specific savepoint instead..."). For cron/worker code that needs per-row isolation so one bad row doesn't roll back the whole batch, use `with self.env.cr.savepoint(): ...` inside the loop instead of `cr.commit()`. Savepoints work in both prod (under the outer cron transaction) and tests (under the outer test transaction). The cron transaction commits the whole batch when the method returns; in tests everything rolls back cleanly. Source: `odoo/sql_db.py::TestCursor.commit` and `Cursor.savepoint()`.
 
 15. **There is NO `sale.subscription` model in Odoo 19** (Enterprise `sale_subscription`). A subscription is a **`sale.order`** with `is_subscription=True`, `plan_id` → **`sale.subscription.plan`** (the recurrence), plus `subscription_state` / `next_invoice_date` / `recurring_monthly`. Any Many2one or relation that targets "a subscription" must point at `sale.order` (filter `domain=[('is_subscription','=',True)]`) — **not** `sale.subscription`, which does not exist and fails at install. The surviving `sale.subscription.*` records are only the plan + wizards/reports (`sale.subscription.plan`, `sale.subscription.report`, `sale.subscription.change.customer.wizard`, `sale.subscription.close.reason.wizard`). Verified on live `nexamain` (odoo-nexa, 19.0): `SELECT model FROM ir_model WHERE model LIKE 'sale.subscription%'`.
