Source provenance

mathjax-go is a source-shaped Go translation of the TeX-to-SVG subset in MathJax 3.2.2 that D2 executes.

Source	Version / commit	License	Relevant surface
MathJax source	3.2.2 / ad8f5c21cb810236551da8c6512ba733e67357ee	Apache-2.0	ts/core, ts/input/tex, ts/output/common, ts/output/svg, and TeX SVG fonts
MathJax components	3.2.2 / 600692ad9d3552cc25f85510d5797bc942ecc9f7	Apache-2.0	component build used to identify the frozen module surface
mhchemParser	4.1.1 npm package, SHA-1 a2142fdab37a02ec8d1b48a445059287790becd5	Apache-2.0	src/mhchemParser.ts for \ce and \pu
Luo-Studio/go-tex	commit 60635a3613c51e710fd5cb57e1d7eeb7b3163a1f	MIT	initial Go translation structure for internal/mhchem; behavior was then corrected against mhchemParser 4.1.1
D2 custom-component assets	D2 commit 541941e895fcdc69ad3109770296dcac670c5be7	mathjax.js: Apache-2.0; polyfills.js: MIT; D2-authored setup.js: MPL-2.0	asset-origin commit used to extract the semantic manifests and exact package/configuration surface
D2 formula/integration snapshot	D2 commit 5666d9337c77a4803b9cd60cb1c5a24439d0f949	MPL-2.0	D2 formula corpus and CI fetch commit; the three oracle assets are byte-identical to the asset-origin commit above and retain their per-file licenses listed in the preceding row

The semantic manifests were extracted from the three assets at D2 commit 541941e895fcdc69ad3109770296dcac670c5be7. The formula corpus and CI fetch the same byte-for-byte assets at D2 commit 5666d9337c77a4803b9cd60cb1c5a24439d0f949; the hashes above are the authoritative identity check for either commit.

The bundle reports MathJax version 3.2.2. Its configured TeX packages are base, mathtools, ams, amscd, braket, cancel, cases, color, gensymb, mhchem, and physics. Its SVG output uses fontCache: 'none'. The call boundary is html.convert(tex, {em: 16, ex: 8}), whose default is display mode, followed by serialization of the container's inner HTML.

polyfills.js is used only by the external oracle. It contains code from XMLDOM and Wicked Good XPath under their respective MIT licenses; none of that code is translated into, embedded in, or distributed as part of the production Go library.
