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.

// E6b — own-wins-over-flat for ERROR-SET per-decl nominal identity. `main`
|
|
// flat-imports `dep.sx` (which authors `IoErr { Net }`) AND authors its OWN
|
|
// `IoErr { Disk }`. A bare `IoErr` reference in `main` resolves to `main`'s OWN
|
|
// author, not the flat-imported one (the querying source's author wins outright —
|
|
// no ambiguity), so `e : IoErr = error.Disk` binds `main`'s set (whose `Disk` tag
|
|
// dep's `IoErr` lacks) while `dep_err()` returns dep's DISTINCT `IoErr`.
|
|
//
|
|
// Fail-before (pre-E6b): the stateless `type_bridge.resolveInlineErrorSet`
|
|
// `findByName` short-circuit interned ONE global last-wins `IoErr`, so `main`'s
|
|
// `IoErr` and dep's `IoErr` collapsed to a single nominal. Whichever author won
|
|
// the global slot, the OTHER module's tag is not in it — so exactly one of
|
|
// `error.Disk` (main) / `error.Net` (dep, in `dep_err`'s body) fails its
|
|
// membership check and the program exits 1.
|
|
//
|
|
// Pass-after: distinct nominal TypeIds — `error.Disk` validates against main's
|
|
// `{ Disk }` and `error.Net` against dep's `{ Net }`, both pass, exit 0.
