Stock Lot Is Archived

This module adds a simple checkbox called "Is Archived" on each lot (serial/lot number) in Odoo. It is separate from Odoo's standard active/inactive switch: a lot marked as archived stays visible and usable, it is just flagged as archived for your own reporting or filtering.

Where you see it: - On the lot form, the checkbox appears after the reference field. Only users in the Inventory Manager group can change it; for other users it is shown read-only. - In the lots list view, an "Is Archived" column is added. - In the lots search filters, a new "Is Archived" filter lets you show only archived lots.

Automatic behaviour: - A scheduled job named "Archive product lots (Is Archived)" is provided. It is created inactive, so you must enable it yourself. When active, it runs once a day and flags lots as archived when two conditions are met: there is another lot for the same product with an expiration date equal to or later than this lot's expiration date, and there is no remaining quantity of this lot in any internal warehouse location. Lots that are already flagged are skipped.

The module touches the stock.lot model and adds a small helper model used by the scheduled job. It depends on the lot expiration features.
