Known Limits

Stated in advance so that the volume cannot quietly grow to cover them.

• Nothing here is a claim about mathematics. Bicategories, coherence and quasi-categories are settled subjects, independent of this series. The volume's only possible contribution is a correct identification of which of them the operator chain instantiates.
• Chapter 2 may end the volume. If the four operators do not compose in a single category, chapters 3 through 6 are vacuous. That outcome is to be published, not routed around.
• A negative result is the likeliest outcome. Composition may be strict, in which case rung 30 is not needed and the volume is one chapter long. This is stated here so that a short volume reads as a finding rather than as a failure.
• The rung ordering is a choice. The ladder this volume is placed against omits its own rungs 29–32 and drops a numeral at 9. Rung 30's position in Part II was assigned in WP-81, not recovered from a source. ASSUME
• The corpus measurements are single-pattern greps. Chapter 6's counts were taken across ten spellings, which is better than one, and still not a proof of absence. Two claims of absence made during the drafting of Part II were later found wrong for exactly this reason.
