Chapter 4: The Five Periods and Eight Teachings¶

[PLANNED] This chapter has not yet been written; what follows is a skeleton. The skeleton is laid out at full-treatment scale: the brief version walks only the trunk of each item, and a later expansion thickens the same outline without restructuring.

• The full classification apparatus; the four modes and four doctrines.
• Three classification schemes side by side: three turnings, four tiers, eight teachings.
• Audited as pedagogical-parameter engineering per Part 19 chapter 6; the self-exemption question: who classifies the classifier.
