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.

// E6a — per-decl nominal identity for UNION decls. A bare UNION reference is
|
|
// non-transitive AND ambiguity-checked at every site, exactly like the enum
|
|
// (0795) and struct (0767) forms. `main` flat-imports two modules that each author
|
|
// a same-name `Pair` union and authors none itself, so EACH of the following bare
|
|
// UNION forms is a genuine collision the source cannot disambiguate — and each must
|
|
// emit the LOUD "type 'Pair' is ambiguous" diagnostic and poison the result, NEVER
|
|
// silently pick a global `findByName` last-wins author:
|
|
//
|
|
// - reflection / type-arg slot `size_of(Pair)`
|
|
// - typed annotation `u : Pair = ---`
|
|
// - type-as-value `t : Type = Pair`
|
|
// - type-category match arm `case Pair:`
|
|
//
|
|
// Fail-before (pre-E6a): the stateless `type_bridge.resolveInlineUnion`
|
|
// `findByName` short-circuit interned ONE global last-wins `Pair`, so every bare
|
|
// form silently resolved to it and the program exited 0.
