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 — per-decl nominal identity for ERROR-SET decls. A bare ERROR-SET reference
|
|
// is non-transitive AND ambiguity-checked at every site, exactly like the struct
|
|
// leaf (0755) and the enum/union leaves (0795/0797). `main` flat-imports two
|
|
// modules that each author a same-name `IoErr` error set and authors none itself,
|
|
// so EACH of the following bare ERROR-SET forms is a genuine collision the source
|
|
// cannot disambiguate — and each must emit the LOUD "type 'IoErr' is ambiguous"
|
|
// diagnostic and poison the result, NEVER silently pick a global `findByName`
|
|
// last-wins author:
|
|
//
|
|
// - reflection / type-arg slot `size_of(IoErr)`
|
|
// - typed error-value annotation `e : IoErr = error.Disk`
|
|
// - type-as-value `t : Type = IoErr`
|
|
// - type-category match arm `case IoErr:`
|
|
// - `!Named` failable channel `-> !IoErr` (E6b audited use surface)
|
|
//
|
|
// Fail-before (pre-E6b): the stateless `type_bridge.resolveInlineErrorSet`
|
|
// `findByName` short-circuit interned ONE global last-wins `IoErr`, so every bare
|
|
// form silently resolved to it; the `!IoErr` channel resolved through
|
|
// `resolveErrorType -> resolveTypeName` straight to that global slot. The program
|
|
// exited 0.
