Hister — license notice for AutoRAG's `hister` datasource
==========================================================

Program:      Hister ("Your own search engine")
Source:       https://github.com/asciimoo/hister
Copyright:    asciimoo and Hister contributors (see the repository history)
License:      GNU Affero General Public License, version 3 or (at your option)
              any later version (AGPL-3.0-or-later)
License text: https://www.gnu.org/licenses/agpl-3.0.txt
              (also the LICENSE file in the Hister repository)

How AutoRAG relates to Hister
-----------------------------
* AutoRAG does NOT contain, bundle, link, vendor, or redistribute any Hister
  source code or binary. Nothing from the Hister repository is copied into
  this package.
* Users install Hister themselves, unmodified, from its own releases
  (https://github.com/asciimoo/hister/releases, `brew install hister`, Docker,
  or Nix), and run it as a separate process (`hister listen`).
* AutoRAG talks to that process only over HTTP, using Hister's public JSON API
  (`GET /search`, `GET /api/config`), the same API Hister's own `hister search`
  command uses. Hister owns its index, its browser extension, its credentials,
  and its optional embedding calls.
* AutoRAG does not modify Hister, and it never hides that Hister is the backend:
  the datasource manifest shown to the agent names Hister, its license, and its
  source URL.
* The `hister` datasource only reads web-page documents (`type:web`). It never
  enables or uses Hister's local-directory indexing.

Combining separate programs that communicate over a network is "mere
aggregation" in the sense of the GNU licenses FAQ
(https://www.gnu.org/licenses/gpl-faq.html#MereAggregation); AutoRAG therefore
stays under its own license (Apache-2.0).

If you run Hister as a network service for other people, AGPL-3.0 section 13
applies to YOU as the operator of that Hister instance: you must offer those
users the Corresponding Source of the Hister version you run (and of any
modifications you made). Running an unmodified upstream release satisfies this
by pointing users at https://github.com/asciimoo/hister.

Obtaining the Hister source for a release you run
-------------------------------------------------
    git clone https://github.com/asciimoo/hister
    git checkout <the version printed by `hister --version`>

This file is a notice, not the license. The authoritative license terms are in
the Hister repository and at the AGPL URL above.
