## Graphs
-The dependency graph covers the six milestones and every edge runs from a dependency to the result that uses it while the node colour encodes the status proved or stated or planned or blocked:
+The dependency graphs are drawn in greyscale and split by milestone. Every edge runs from a dependency to the result that uses it. A box is a result named after a paper statement, an ellipse is a supporting result, and a dashed box labelled with a milestone is a result defined in another diagram. The overview gives the shape of the whole development:
-
+
+
+The details are then one diagram per milestone:
+
+### M1, binding and reduction
+
+
+
+### M2, metatheory and checks
+
+
+
+### M3, subsystem
+
+
+
+### M4, parallel reduction
+
+
+
+### M5, metaterms and the named calculus
+
+
The rule sketch gives the transition system generated by the rules B and Gc and R:
-
+
The reduction graph gives the bounded reduct set of the term that applies the duplicating identity to a variable with every edge labelled by its rule and with the normal form marked:

+(* The missing invariants.
+
+ The measure proof needs the reduction rules to preserve freeness, in the
+ sense that a variable that is not free in a term contributes nothing
+ to the measure. Concretely the paper uses
+
+ x notin fv(t) implies Mx(x,t) = 0
+
+ for the Gc case and, through Lemma A.2, for the R and RX cases. That
+ property is not true on the raw named syntax: a metavariable may carry
+ an annotation variable that an enclosing substitution binds. The
+ metaterm X_[x][x/y] below is the smallest witness. Its free variables
+ are {y}, it therefore has no free occurrence of x, yet Mx(x, .) = 1. *)

+(* Lemma A.1, invariance of Mx and s under the C equation, also needs the
+ invariant. The two terms below are related by C with x = 0, y = 1, y not
+ free in u and x not free in v, yet their sizes and Mx values differ: the
+ occurrences of 1 and 0 that sit inside the metavariable annotation but
