THIRD-PARTY NOTICES — Past the Magic (pastthemagic.com) ========================================================= This file is the authoritative software bill of materials (SBOM) for the PRODUCTION (runtime) dependencies of Past the Magic, a web-based LC-3 simulator and C-to-LC-3 explorer. Past the Magic itself is proprietary — see LICENSE at the repository root. Scope: this covers only dependencies that ship in the built web application (apps/web) and are bundled into the code served to users. Development-only tooling (TypeScript, ESLint, Vite, Vitest, Playwright, Prettier, etc.) is NOT included here because it is not distributed with the product. The first-party workspace packages @lc3/core, @lc3/cc, and @ptm/valuation are part of this project (same proprietary license as the rest of the repository) and are not third-party dependencies; they are listed for completeness only. License data below was read directly from each installed package's "license" field in its package.json and, where present, its LICENSE file under node_modules — not inferred or guessed. It was cross-checked against `pnpm licenses list --prod` (see the "licenses" script in package.json to regenerate this listing). COPYLEFT SCAN — RESULT: CLEAN ------------------------------ All 23 third-party production packages below were scanned. None declares a GPL, LGPL, or other copyleft license. Twenty-one are MIT (permissive) and two (the IBM Plex font packages) are OFL-1.1 (permissive, font-specific, no network-source or copyleft obligation). There is no license conflict with using these third-party components in Past the Magic, which is proprietary. ============================================================================= PART 1 — DIRECT PRODUCTION DEPENDENCIES (apps/web/package.json) ============================================================================= Package Version License First-party? ---------------------------- --------- -------- ------------ @codemirror/commands 6.10.4 MIT no @codemirror/lang-cpp 6.0.3 MIT no @codemirror/language 6.12.4 MIT no @codemirror/lint 6.9.7 MIT no @codemirror/state 6.7.1 MIT no @codemirror/view 6.43.6 MIT no @fontsource/ibm-plex-mono 5.2.7 OFL-1.1 no @fontsource/ibm-plex-sans 5.2.8 OFL-1.1 no @lc3/cc 0.1.0 Proprietary YES (this project) @lc3/core 0.1.0 Proprietary YES (this project) @lezer/highlight 1.2.3 MIT no @ptm/valuation 0.1.0 Proprietary YES (this project) @vercel/analytics 2.0.1 MIT no codemirror 6.0.2 MIT no react 19.2.7 MIT no react-dom 19.2.7 MIT no ============================================================================= PART 2 — TRANSITIVE PRODUCTION DEPENDENCIES ============================================================================= These are not declared directly in apps/web/package.json but are pulled in by the direct dependencies above and are also bundled into the shipped application.

This license is copied below, and is also available with a FAQ at: http://scripts.sil.org/OFL ----------------------------------------------------------- SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 ----------------------------------------------------------- PREAMBLE The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others. The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives. DEFINITIONS "Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation. "Reserved Font Name" refers to any names specified as such after the copyright statement(s). "Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s). "Modified Version" refers to any derivative made by adding to, deleting, or substituting -- in part or in whole -- any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment. "Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.

These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user. 3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users. 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission. 5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license.
