Third-Party Notices
===================

late.sh's own source is licensed under FSL-1.1-MIT (see LICENSE and
LICENSING.md). This file lists third-party programs that late.sh bundles,
installs, or runs, together with their licenses and where their source can be
obtained. It does not change the license of late.sh itself.


NetHack
-------

late.sh hosts NetHack as a door game (the "NetHack" screen). The game binary is
compiled from official upstream source inside the service container (see the
"nethack-build" stage in the Dockerfile) and is run as a local child process;
players reach it remotely over the late.sh SSH server.

  Program:    NetHack 5.0.0
  License:    NetHack General Public License (NGPL)
              https://www.nethack.org/common/license.html
  Copyright:  NetHack, Copyright 1985-2026
              by Stichting Mathematisch Centrum and M. Stephenson.
  Upstream:   https://www.nethack.org/
              https://github.com/NetHack/NetHack
  Installed:  Built from the official upstream source release in the Dockerfile
              ("nethack-build" stage). The source tarball's SHA-256 is verified
              against the checksum published on nethack.org before building.
  Source:     The complete, corresponding machine-readable source is the pinned
              upstream release tarball recorded in the Dockerfile
              (NETHACK_URL / NETHACK_VERSION / NETHACK_SHA256), also available
              from the upstream sites above. Our build recipe is the Dockerfile.
  Modified:   Yes, build configuration only. Before compiling, the
              "nethack-build" stage edits include/unixconf.h via the sed commands
              in the Dockerfile (these are part of our corresponding build
              recipe):
                - sets VAR_PLAYGROUND="/var/games/nethack-var" so writable game
                  state (saves, bones, locks, record) lives on a persistent
                  volume separate from the read-only data directory;
                - removes the SHELL and SUSPEND defines to disable NetHack's
                  in-game shell-escape ('!') and suspend ('^Z') commands, since
                  the game runs as the service user inside the late.sh container.
              No other source is patched and no game data files are altered.

NGPL compliance notes:

  - NetHack's own copyright, license, and warranty-disclaimer notices are part
    of the upstream source tree we build and are kept intact in the service
    image (e.g. the distributed dat/license and the source's copyright headers).
  - late.sh does not distribute copies of the NetHack program to players; it
    only lets them play it over the network. The NGPL is a GPLv2-style license
    with no network-service copyleft clause, so remote play does not trigger a
    source-distribution obligation.
  - Because we now build the binary ourselves, if you redistribute a build of
    late.sh that includes the NetHack binary (for example, by publishing the
    Docker image), the NGPL requires you to also make the corresponding source
    available. Keep the pinned "Source" pointer above (the exact upstream
    tarball we compile) and the Dockerfile build recipe with the distribution so
    recipients can obtain and rebuild that source, and keep NetHack's bundled
    license notices in place.

NetHack is a trademark in some jurisdictions; the name is used here only to
identify the game, not to imply endorsement by the NetHack DevTeam.
