The compiler concept is declare/define (comptime type construction); the
old "reify" framing is gone from the entire repo.
- Rename: PLAN-REIFY → PLAN-METATYPE, CHECKPOINT-REIFY → CHECKPOINT-METATYPE,
PLAN-POST-REIFY → PLAN-POST-METATYPE (both rewritten around declare/define);
examples 0614/0615/0617 → comptime-metatype-* (+ their expected/ triplets),
headers rewritten.
- Scrub reify from design/execution-evolution-roadmap.md (§7 step 3 contracts,
§8.1, §9 decisions, §10 gates) → declare/define / comptime type construction.
- core.sx prelude pointer + parser.test.zig surface lock updated to the
declare/define builtins (define(handle, info) -> Type; EnumInfo.name).
No behavior change; renamed examples match their renamed snapshots. Full
suite green (673), all unit tests pass. Zero `reify` tokens remain in
src/docs/sx/examples.
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.
