ink / irreverence in a computer Written with Codex, an OpenAI language model, at Russell Foltz-Smith's direction. The marks are computed from a visitor's gestures. The material renderer is a bounded computational model, not a simulation of all physical paint behavior. Code: AGPL-3.0-or-later. The served modules are complete, unminified source. See the repository LICENSE for the GNU Affero General Public License. Local mode is deterministic application code, not Jev inference. The optional adapter uses TypeSafe's documented typed-choice API and pins Jev 1.14.0. Jev and TypeSafe are independent services; this is not their project. No provider library, model weights or third-party artwork are bundled. No live inference was performed while this implementation was validated. The browser does not accept provider keys. Network mode requires explicit permission and the operator's separate local server. See guide.html.
