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.

// A genuinely-undeclared type name used as a field type inside a MAIN-file
|
|
// GENERIC struct must emit a clean "unknown type" diagnostic, not silently
|
|
// compile.
|
|
//
|
|
// The `UnknownTypeChecker` used to SKIP generic structs entirely ("their field
|
|
// types reference the struct's own `$T`, resolved at instantiation"). That skip
|
|
// was too broad: a field type like `bad: MissingType` — which is NOT a type
|
|
// param and names no declared type — fell through the type leaf's empty-struct
|
|
// stub and the struct silently compiled, mis-sizing every downstream load.
|
|
//
|
|
// The checker now walks generic-struct fields with the struct's own type params
|
|
// (`$T`) in scope: `good: T` resolves (it IS a param) while `bad: MissingType`
|
|
// is reported. A value-param position (a `Vector` lane count, a `$N: u32` arg)
|
|
// is still skipped, so a valid generic struct keeps compiling unchanged.
|
|
//
|
|
// Expected: `error: unknown type 'MissingType'` pointing at the field; exit 1.
|
|
// Regression (stdlib E3).
