The trio the author decided on 2026-09-20 is now all built: def is CL's defparameter — its initialiser runs on every daemon re-run, unguarded, so an edited initialiser repaints the same storage on C-c C-c plus re-run — defonce (Clojure's name for CL's defvar, per the author) initialises once behind the .init~once. flag, and defconst stays the image. One parse arm reads both forms; the difference is Ast.reinit, carried to Tast.global's grerun. Emit.startup_plan gives a def no guard flag, and Check.check_global lifts every def initialiser — zero and literal included — into global/<n>, so the host's startup reaches it through the function cell and a re-evaluated def swaps it (Session's def_inits; Emit.redefinition declares the cell for a non-sibling target). The old defvar spelling is refused with the rename and both compiling spellings, and every program, test, doc and editor list is swept — except sand.flan, the author's live WIP, whose seven defvar lines are flagged in FIX.org and keep its three dependent tests red on this branch.

;;;; nth was an alias of at, and an asymmetric one: the checker accepted it as

;;;; a read, but parse.ml and place_of_expr both match only [at], so
|
|
;;;; (set (nth a i) x) and (addr (nth a i)) were refused while the [at] forms

|
;;;; worked. Two names documented as identical that disagree about writing are
|
|
;;;; worse than one name, so nth is gone and this pins the removal: it must

;;;; fail as an unknown name, not quietly resolve to at again.
