Neoism
======

Neoism is a terminal-first workspace for code, notes, agents, and multiplayer
editing. The great majority of Neoism — its editor, agent runtime, workspace
daemon, sync/CRDT layer, notebooks, drawing surfaces, extensions system, and UI
chrome — is original work by the Neoism contributors, licensed under the MIT
License (see LICENSE).

Neoism's terminal core and GPU renderer descend from Rio Terminal, which in turn
descends from Alacritty. Those and the other third-party components listed below
retain their original copyright and license notices. Where a source file carries
an upstream copyright header, that header is authoritative for that file.


Terminal core & renderer lineage
---------------------------------

Rio Terminal — MIT License, Copyright (c) 2022-present Raphael Amorim and
contributors. Neoism's `sugarloaf` (GPU renderer), `teletypewriter` (PTY),
`corcovado`, `copa`, `neoism-terminal-core`, `neoism-backend`, and parts of
`neoism-window` are derived from Rio. Neoism extends the sugarloaf renderer with
additional first-party subsystems (notably the virtual-surface editor/markdown/
agent rendering path and shader overlay); the Rio-derived code remains under
Rio's copyright and MIT license.

Alacritty — Apache-2.0 License, Copyright (c) The Alacritty Project. The terminal
grid model (`neoism-terminal-core/src/crosswords`) and VTE parser lineage
originate in Alacritty; affected source files retain their Alacritty attribution.
