Deck — third-party attributions
====================================

This project is 0BSD licensed (see LICENSE) — you may use it with no attribution required. It bundles or depends on the
following third-party work, each under its own permissive license.

Lucide icons
------------
The icon set exposed via gpui-component's `IconName` (and bundled as SVGs by
`gpui-component-assets`) is Lucide. Lucide is licensed under the ISC License.

    Copyright (c) for portions of Lucide are held by Cole Bemis 2013-2022 as
    part of Feather (MIT). All other copyright (c) for Lucide are held by the

    Permission to use, copy, modify, and/or distribute this software for any
    purpose with or without fee is hereby granted, provided that the above
    copyright notice and this permission notice appear in all copies.

ISC is a permissive, MIT-equivalent license — free for personal and commercial
use. Keep this notice if you redistribute the bundled icons. https://lucide.dev

GPUI and gpui-component
-----------------------
The framework crates are pulled from git (pinned in Cargo.lock), not crates.io,
and are all Apache-2.0:

- gpui, gpui_platform, sum_tree — from Zed (https://github.com/zed-industries/zed,
  pinned at commit 86effffd). Apache-2.0, © Zed Industries.
- gpui-component, gpui-component-assets — from
  https://github.com/longbridge/gpui-component (pinned at commit dadfca97).
  Apache-2.0, © Longbridge.

GPL-3.0-or-later components (matters mainly for closed-source binaries)
.......................................................................
Zed's logging/tracing crates — zlog, ztracing, ztracing_macro — are
GPL-3.0-or-later, and the git gpui stack links them into the binary via the
chain `gpui -> sum_tree -> ztracing -> zlog`. sum_tree itself is Apache-2.0; it
is simply the carrier whose unconditional `ztracing` dependency drags the three
GPL crates in. Deck did not add them — Zed wired ztracing into sum_tree in Dec
2025 (PR #44147), so they are present on Deck's pinned git commit and on current
gpui main, but NOT in the Oct-2025 crates.io 0.2.2 snapshot. At Deck's default
build they are compile-time no-ops (dormant Tracy instrumentation, active only
behind an env-var-gated `--cfg ztracing`).

GPL obligations attach to DISTRIBUTION, not to building or running:

  - Local / internal-only use: no obligation, on any channel.
  - Open-source fork (source already public): GPL-3.0's source-availability
    requirement is satisfied trivially; nothing further to do.
  - Closed-source / proprietary binary: you cannot statically link GPL-3.0 code
    and keep the combined work proprietary. Build on the permissive crates.io
    pair (`gpui = "0.2"`, `gpui-component = "0.5"`), whose `gpui_sum_tree`
    carries none of Zed's git tracing crates, so the binary is free of the
    GPL-3.0 chain.

Deck's own source is 0BSD regardless. See deny.toml for the scoped license
exceptions covering exactly these three crates, and zed-industries/zed#55470 for
the upstream tracking issue. This is a summary, not legal advice.
