0004 – Licensing
================

:Status: Accepted
:Date: 2026-10-04

Decision
--------

* ``ishtaria-server`` – **AGPL-3.0-only**: anyone may run a world, but
  modified servers offered over the network must publish their source.
  This keeps the federation open and prevents closed forks.
* ``ishtaria-core``, ``ishtaria-client``, ``ishtaria-worldgen``,
  ``ishtaria-protocol`` – **MIT**: easy adoption, alternative clients and
  implementations of the protocol are welcome.
* ``ishtaria-docs``, ``ishtaria-content`` – **CC BY-SA 4.0**.

Consequences
------------

* An official hosted world and managed hosting of worlds remain viable
  business models alongside a fully open ecosystem.
