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 — ambiguity guard for an ERROR-SET name in a CLOSURE-LITERAL return
|
|
// annotation (`closure(() -> !IoErr { … })`). `main` flat-imports two modules
|
|
// that each author a same-name `IoErr` and authors none itself, so the closure
|
|
// literal's `-> !IoErr` channel is a genuine collision the source cannot
|
|
// disambiguate. It must emit the LOUD "type 'IoErr' is ambiguous" diagnostic and
|
|
// poison the channel — NEVER silently pick a global `findByName` last-wins author.
|
|
//
|
|
// NOTE on fail-before/pass-after: unlike the OWN-WINS sibling (0813), this
|
|
// AMBIGUITY case does NOT fail-before on attempt-1's binary. The pre-lowering
|
|
// closure-shape pass (`convergeClosureShapeSets` → `recordClosureShape`) resolves
|
|
// every closure literal's return annotation through the source-aware
|
|
// `resolveType` (`resolveTypeWithBindings`), which attempt-1 already routed
|
|
// error-set authors through — so the ambiguity is detected there and reported
|
|
// regardless of `lowerLambda`. (For a `-> !Named` set that pass bails early after
|
|
// resolving, so the OWN-WINS membership in 0813 still flowed through the stateless
|
|
// `lowerLambda` path that attempt-2 fixes.) This example is the standing GUARD
|
|
// that the lambda `-> !Named` ambiguity stays reported across both source-aware
|
|
// sites; 0813 is the one that exercises attempt-2's `lowerLambda` channel fix.
