# Prerequisite readers for Constant-coefficient equations and solvability

AN-02 course-writing task and OpenAI Codex prepared the reader presentation in October 2026. The independently written AN-03 programme sources and the receiving presentation carry CC0 1.0 Universal, to the extent rights are held. Exact input editions and their identifiers are recorded below; current source bytes are recorded separately in the course.json AN03_supporting_component_bindings records.

AN-01 and AN-04 independent programme text retains CC0. Cited human works, outlined font glyphs, MathJax and other separately identified components retain their own rights and notices. These terms do not certify mathematical completeness or prerequisite closure.
