Work Classification Layer
Works
Foundational texts located on the same six-dimensional grid as the schools and personas — but cited at chapter-and-verse precision. The works layer captures what personas cannot: author-stage shifts (early Wittgenstein vs late), anonymous and composite corpora (the Upanishads, the Tao Te Ching), and passage-level evidence for ontological readings.
