it.1/it.2 shipped; it.2's D1 resolved the original two open spec
questions (same-family mutual rule; foldl=structural). it.3 BLOCKED
on a fundamental design-thesis gap: the totality story recognised
only ADT-structural recursion; the corpus sweep proved a second
canonical total scheme (Int-bounded well-founded recursion, incl.
branching build(d-1),build(d-1)) is overlooked and the milestone
as-specified makes it inexpressible — failing its own
feature-acceptance gate. Records the full option analysis with a
recommendation (A1: trichotomy + a documented non-negative-entry
obligation), flagged as a USER decision because it trades against
the purity pillar the user co-designed. Next: user decision →
it.2b → it.3 re-dispatch from c992eb9.
