# Third-party notices

Lingostack includes or compiles code and assets from third-party projects. The
release archive retains the license files shipped by Composer dependencies in
`vendor/`. JavaScript dependency metadata and license texts are available from
the human-readable source repository and its lockfile.

## Runtime PHP packages

- Action Scheduler by Automattic — GPL-3.0-or-later license. Lingostack is
  GPL-2.0-or-later, which permits the combination; the distributed whole is
  therefore effectively GPL-3.0-or-later. The package is bundled under
  `vendor/woocommerce/action-scheduler/` and loaded by
  `ActionSchedulerLoader`, which defers to a newer copy shipped by another
  plugin (WooCommerce most commonly) through Action Scheduler's own version
  negotiation.
- Masterminds HTML5 — MIT license.
- Gettext PHP Scanner, Gettext and Gettext Languages (php-gettext) — MIT license.
- Two files from Gettext WordPress Scanner by 10 Quality, carried in src/GettextDomains/Scanner/ with their attribution — MIT license.
- PHP Parser by Nikita Popov — BSD-3-Clause license.

## Admin application

- Shopify Polaris, Polaris Icons, and Polaris Tokens — Shopify's Polaris license.
  That license restricts use to interfaces that integrate with or interoperate
  with Shopify software or services. Lingostack intentionally retains Polaris;
  marketplace acceptance of this dependency is an acknowledged release risk.
- TanStack Query and TanStack Virtual — MIT license.
- Motion — MIT license.
- nuqs — MIT license.
- WordPress Scripts and its build dependencies — licenses declared by their packages.

## Flag assets

The bundled flags are derived from `flag-icons`.
