Fold the adversarial-review corrections into the program plan + design-of-record:
- atomics is 100% net-new (no scaffolding; lower.zig 'ordering' is comparison-only)
- context is already an implicit *Context param (not TLS) — B1.1 rescoped
- abi(.pure) exists but is inert (no naked emission) — B1.0 rescoped
- B1.3 switch-stress harness is the first deliverable + mandatory stack guards
- Stream C gated on a named TSan/ASan + run-N stress harness, not a footnote
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.
