Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// 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).
