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.

// issue 0134 — a same-name `error` set collapses into a namespaced import's
|
|
// set (error sets lack per-decl nominal identity).
|
|
//
|
|
// `EventErr` is declared locally as `error { Boom }`, but
|
|
// `#import "modules/std.sx"` also carries `event.EventErr` (an error set with
|
|
// tags Init/Register/Wait). Because error-set DECLARATIONS are not given
|
|
// per-decl nominal identity (unlike struct/enum/union under E6a) —
|
|
// `registerErrorSetDecl` registers via the flat `findByName`-dedup path — the
|
|
// local `EventErr` collapses into the imported one, losing its own `Boom` tag.
|
|
//
|
|
// So `raise error.Boom` / `r == error.Boom` are checked against the IMPORTED
|
|
// set, which has no `Boom`.
|
|
//
|
|
// EXPECT (today): build FAILS —
|
|
// error: error tag 'error.Boom' is not in error set 'EventErr'
|
|
// EXPECT (after fix): prints `own EventErr.Boom`, exit 0.
|
|
//
|
|
// Proof it's the collision: rename `EventErr` -> `MyErr` and it compiles and
|
|
// prints. The reference side (`!EventErr` → resolveNominalLeaf) is already
|
|
// visibility-aware from issue 0132's broader fix, but it is dormant until the
|
|
// local declaration gets its own TypeId. See the .md.
