The Iteration-discipline milestone was scoped from fieldtest finding
F1 (a [friction] item whose own minimal recommendation was "tighten
DESIGN.md") and escalated into "retire tail-app, recursion total-by-
construction, add Diverge". it.3 BLOCKED on the most LLM-natural
tree-builder shape (build(d:Int)=Node(1,build(d-1),build(d-1))),
which the thesis makes inexpressible; the only escape (A1/it.2b)
concedes the language's first documented-unenforced totality
precondition (no Nat/refinement enforcement — Decision 4). it.2's
NonStructuralRecursion checker is not a stable additive stopping
point — it half-enforces a dichotomy only the destructive it.3
completes.
User decision (2026-05-16): full revert to the pre-milestone state.
Both it.1 and it.2 come out via one forward iteration (main
sacrosanct). tail-app/structural recursion remain the iteration
mechanism exactly as before 9973546. Feature-acceptance clause 3 is
kept (it is the tool that diagnosed the over-escalation); F1/F4 get
the honest DESIGN.md documentation note the fieldtester actually
recommended. The genuine total-Int-recursion ambition is re-
sequenced behind a future Nat/refinement milestone, not diluted to
fit today. Stateful-islands (P2, the real ~/sma_factory.myc
descendant) is untouched.
Grounding-check (brainstorm Step 7.5): PASS after one factual
correction (the ctx()-arm removal split). Spec is the contract for
the revert planner+implement.
