Work used: The Law of Success in Sixteen Lessons (1928), Ralston University
Press. PD basis: US term expiration — a 1928 work, so PD in the US since
1 Jan 2024 (95-year term; US Copyright Office Circular 15A). This is a clean
term-expiration basis, not a contested non-renewal argument.

Not used: Think and Grow Rich (1937). Its PD status depends only on a
(contested) copyright-non-renewal claim, and it is protected under life+70 abroad
until 2041. We deliberately took the safe path. See SOURCE_MANIFEST.md for the
full reasoning and ../CORPUS_BOUNDARY.md / ../QUOTE_AUTHENTICITY.md.
