User picked the declaration-vs-definition split over reserve/complete.
declare() returns a forward nominal Type handle (named from the :: LHS);
define(handle, info) fills its body. reify(info) stays the one-shot
sugar. Updated PLAN-REIFY Phase 4 + Contract 5 + CHECKPOINT-REIFY.
User-directed API decision: replace the reify_rec((self)=>...) closure
with an explicit reserve() -> Type handle + complete(handle, info) pair.
reserve() returns a forward nominal Type usable freely in any later
TypeInfo (*List, []List, and across types for mutual recursion the
one-self closure couldn't express); reify(info) stays as the one-shot
sugar. Maps onto existing reserve->complete machinery. Captured in
PLAN-REIFY Phase 4 + Contract 5 + CHECKPOINT-REIFY.
REIFY Phase 0.2 (Phase 0 complete). Lowering.reifyType (lower/nominal.zig)
reads the flat-enum TypeInfo literal off the AST, synthesizes an
ast.EnumDecl, and feeds it through the SAME type_bridge.buildEnumInfo
path source enums use — so the minted type is byte-identical to a
hand-written `enum { value: i64; closed; }` and flows through enum
codegen (layout / construct / match) UNMODIFIED (Contract 2).
Wired at the `E :: reify(...)` const-decl hook in lower/decl.zig
(replacing the Phase-0.0 loud bail). Unsupported argument shapes bail
loudly via reifyBail — never a silent default. The generic.zig inline
reify path now reports it's only supported in a `::` binding (Phase 0).
examples/0614 green: reify a {value: i64, closed} enum, construct
.value(3) and .closed, match both -> "value 3" / "closed". Full suite
green (670 examples, 447 unit).
Add the async-first execution-model roadmap (comptime JIT spine, colorblind
fibers/Io, atomics, hot-reload) with all seven decisions resolved and
three-way reviewed, and carve the first stream: comptime type_info/reify
(PLAN-REIFY + checkpoint) — the codebase-validated foundation for channel
result types and race's synthesized tagged union.
