Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.

// Source-aware forward-alias fixpoint (R5 §4, E1.5). A forward identifier alias
|
|
// `A :: B` must resolve its target `B` AS SEEN FROM ITS OWN SOURCE, not via the
|
|
// global `type_alias_map` (which is last-wins across every module).
|
|
//
|
|
// `main` authors a forward alias `A :: B` and its own `B :: u64`. The namespaced
|
|
// import `ns :: #import ".../dep.sx"` ALSO authors a top-level `B :: u8`; being
|
|
// scanned after main's `B`, dep's alias is what the GLOBAL `type_alias_map["B"]`
|
|
// ends up holding (last-wins). A global forward-alias fixpoint therefore bound
|
|
// `A` to dep's `u8` — re-opening 0105 one layer down. The source-aware fixpoint
|
|
// resolves `A`'s target against MAIN's source, binding the local `B :: u64`.
|
|
//
|
|
// Observable: a runtime 300 coerced into an `A`-typed slot round-trips as 300
|
|
// when `A` is `u64` (correct) and truncates to 44 when `A` is wrongly `u8`.
|
|
// The direct reference `b : B` already resolves source-aware via E1's nominal
|
|
// leaf, so it pins the same `u64` for contrast. Regression (stdlib E1.5).
