# Third-party notices ## Claude How-To learning-topic and design reference This community Codex learning website adapts the 60 learning topics, original module organization and learning-navigation principles of [Claude How-To](https://luongnv.com/claude-howto/) by [luongnv89](https://github.com/luongnv89/claude-howto). The learning-topic organization remains adapted under the original MIT notice. The current version 2.5 local design candidate uses an original interface maintained in assets/atelier/. The earlier directly reused stylesheet, derived templates and motion remain in assets/reference/ as historical, attributed source; its landing CSS and typewriter are no longer loaded. Source inspected: commit `188f468893231cbe4525f45e657d554746232072`, particularly `scripts/website_templates/landing.css`, `landing.js`, and `landing.html.j2`. Copyright (c) 2024 luongnv89. Licensed under the MIT License. The complete original notice is included in [assets/licenses/claude-howto-MIT.txt](assets/licenses/claude-howto-MIT.txt). The Codex curriculum is newly authored and is now presented in English following the user's revised direction. Names, commands, capabilities, and examples are checked against Codex sources rather than translated mechanically from the Claude lessons. The current interface uses Manrope, a cool-white canvas and restrained cobalt. Its original Task → Change → Check workbench is an illustration of bundled practice files, not a live Codex session. All source attribution and notices are retained. This site is not endorsed by or affiliated with the original author, OpenAI, or Anthropic. ## Self-hosted fonts - **Fraunces**: Copyright 2018 The Fraunces Project Authors.

[Official project](https://github.com/JetBrains/JetBrainsMono). SIL Open Font License 1.1; full notice in [assets/licenses/jetbrainsmono-OFL.txt](assets/licenses/jetbrainsmono-OFL.txt). Font files are unmodified full variable TTFs from the official [Google Fonts repository](https://github.com/google/fonts), served locally with the site. No runtime Google Fonts request is needed. Source ref, filenames, glyph checks, and hashes are documented in [docs/design-sources.md](docs/design-sources.md). The current presentation uses Manrope for display, interface and reading, and JetBrains Mono for code and technical labels. Retained Fraunces resources belong to historical designs and retain their complete notices. The font files and OFL notices were already present; the refinement does not introduce a new external font resource. Source and license check date: 21 October 2026 (Asia/Bangkok). No paid asset, subscription, or specialist service was purchased. ## Lucide SVG icons The interface can use local SVG icons from [Lucide](https://github.com/lucide-icons/lucide), obtained at commit `c29c276f16590cf017126671535ad8c792be64d8`. Copyright (c) 2026 Lucide Icons and Contributors, ISC License. Feather-derived icons additionally carry the MIT License, Copyright (c) 2013-present Cole Bemis. The complete original combined notice is included in [assets/licenses/lucide-LICENSE.txt](assets/licenses/lucide-LICENSE.txt). Local files: `book-open.svg`, `route.svg`, `arrow-right.svg`, `chevron-down.svg`, `check.svg`, `search.svg`, `terminal.svg`, `sparkles.svg`, `git-branch.svg`, `plug.svg`, `shield.svg`, and `code-2.svg` (the last is upstream `code-xml.svg`, unchanged apart from the filename). Files are standalone SVGs, not an installed package or hosted API. ## Redesign references [Linear Method](https://linear.app/method), [Framer Academy](https://www.framer.com/academy/) and [CodeCrafters](https://codecrafters.io/) were inspected on 22 October 2026 as editorial, course-navigation and practice references. Linear Docs and Boot.dev informed earlier iterations. Their code, logos, illustrations, textures and screenshots are not incorporated in this website. No license to those proprietary resources is implied by the reference links. The project-local design record identifies the mechanisms adapted and the earlier design decisions superseded. ## Mermaid — build-time semantic diagrams The 60 original course diagrams are compiled with [Mermaid](https://mermaid.js.org/), pinned browser bundle **12.2.0** from the [official npm release](https://registry.npmjs.org/mermaid/-/mermaid-12.2.0.tgz). Mermaid is MIT licensed, Copyright (c) 2014–2022 Knut Sveidqvist. Its complete original notice is retained in [assets/licenses/mermaid-MIT.txt](assets/licenses/mermaid-MIT.txt). Sources and source hashes are in content/diagrams.json and evidence/diagram-build-report.json. Mermaid is used only to build static SVGs. Its JavaScript bundle is not delivered as a runtime dependency or fetched by the learner. The SVGs carry original lesson-specific relationships and text, not proprietary reference artwork. Package/source terms were checked 21 October 2026; no cost, account, subscription or paid service is involved. ## Original compact diagrams and motion The 120 compact overview SVGs in `assets/diagram-overviews/` are original project artwork generated by `scripts/build-overviews.cjs`: 60 lesson summaries with separate desktop and mobile layouts. They are not Mermaid-rendered outputs, screenshots, traced reference artwork, or an imported icon/diagram pack. Their full semantic counterparts remain in `assets/diagrams/` under the build-time Mermaid notice above. The summary catalog records the corresponding full-source hashes for maintenance. `course-motion.mjs` and `course-motion.css` are original project code, with no third-party animation runtime or media asset. The reader retains course-motion.mjs; the old course-motion.css is not loaded. The current landing uses original assets/atelier/motion.mjs and workbench.mjs, with a short entrance and user-controlled tabs. There is no autoplay; reduced motion removes movement. The historical source-derived reference-motion.mjs is retained but not loaded. The workbench never executes Codex commands. Existing font/icon notices still apply wherever those resources appear in the illustration. ## Agent Plugins JSON schema snapshots The two software schemas `labs/workflow-plugin/schemas/plugin.schema.json` and `mcp.schema.json` come from [Agent Plugins](https://github.com/agentplugins/agent-plugins-spec) at commit `ff8ab5e392cc87bd88d87c060815a87490e51003`, under `schemas/1.0.0/`. The pinned [licensing declaration](https://github.com/agentplugins/agent-plugins-spec/blob/ff8ab5e392cc87bd88d87c060815a87490e51003/LICENSE.md) assigns software schemas to Apache License 2.0. The full unchanged license is retained in [assets/licenses/agent-plugins-Apache-2.0.txt](assets/licenses/agent-plugins-Apache-2.0.txt) and within the downloadable lab at [labs/workflow-plugin/schemas/Apache-2.0.txt](labs/workflow-plugin/schemas/Apache-2.0.txt). These schema files were previously reformatted with unchanged JSON values. The legal correction on October 21, 2026 restored their exact upstream bytes. Exact source URLs, local/upstream hashes and the modification/restoration history are in [SOURCE-NOTICE.md](labs/workflow-plugin/schemas/SOURCE-NOTICE.md), alongside the [schema README](labs/workflow-plugin/schemas/README.md). The complete pinned upstream tree contains no NOTICE-named file, and no separate per-file attribution header was removed. This scoped Apache notice applies to the two schema snapshots, not to the course's original lessons, validator or fictional fixtures, nor to differently licensed upstream documentation. ## Prism syntax highlighting (2.6 local edition) PrismJS 1.30.0, MIT license. The core and selected official language grammars are bundled in `assets/atelier/vendor/prism.js`; the complete notice is in `assets/licenses/prism-MIT.txt`. Source: https://github.com/PrismJS/prism/tree/v1.30.0 . Downloaded from the official npm registry; archive SHA-256 `ac16a9106a28c53b6a6313993c816a3a02525fdfefd7614fc1703df915a9fc11`. No CDN or external runtime request. Token colors are original course CSS.
