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.

// Variadic heterogeneous type packs — step 3: `$args[$i]` in

|
// fn-pointer type literals.
|
|
//
|
|
// `(*void, $args[0]) -> $args[1]` is the shape step 5's generic
|
|
// `Into(Block) for Closure(..$args) -> $R` body needs for its
|
|
// trampoline:

// typed_fn : (*void, $args[0], $args[1], ...) -> $R =
|
|
// xx block_self.sx_fn;
|
|
// — the trampoline's invoke slot is typed against the pack
|
|
// positions to bridge the Block ABI to the sx closure.

//
|
|
// This test exercises the same plumbing on a smaller scale: a
|
|
// local var with a fn-pointer type whose param + return types
|

// both interpolate through `$args[$i]`.
