030: why "it should auto-connect" did not. The LCXL was dark because the loaded
track was a 0-byte file (the surface was right); the orbits were a real
regression, tidal-ardour-autoroute disabled, with 1-4 and 10-12 surviving as
leftovers so it read as "half works". Root cause: both reconcilers lived only in
$HOME, unversioned. Now one authored inventory, three consumers.

031: the #94 remap finished corpus-wide, 169 files all shift +1. Two systemic
bugs that only a corpus-wide run could surface — a depth-blind chain-step
boundary, and commenting out a $-step that was a partial application operand
(an arity bug no paren checker can see). Verified by diffing before/after SETS,
not counts.
