Blocking on exact head 1cd0636. I reproduced two public-contract failures independently of CI. (1) PodView.length only recognizes the original immutable local whose initializer is NativePodView. With const direct: PodView
= arena.podView(...); const alias = direct; alias.length, emitted IR calls js_native_pod_view_length for direct but routes alias.length through the generic object-property PIC/js_object_get_field_ic_miss. NativePodView is not an ordinary ObjectHeader, so an ordinary value alias loses the promised length behavior. Please propagate PodView metadata through safe LocalGet aliases or lower typed PodView.length through the validating helper, and add an alias regression. (2) perry/native type aliases are registered only when the main lowering pass reaches the import declaration. Static imports are hoisted: a valid module with type Header = pod<{ flags: u32 }>; followed by the perry/native import lowers Header as Generic(base="pod", field Named("u32")), and sizeof() fails because it is not PerryPod. Please pre-register these imports before any type extraction/pre-registration pass and add an import-after-use regression. Focused HIR tests (16/16), native_arena runtime tests (14/14), and the generated-stub test pass, but they cover only the direct/import-first path. No version bump needed.

- Around line 17-20: Update pod_layout_intrinsic_is_shadowed, used by
pod_layout_intrinsic_name, to use ctx.shadows_unqualified_global(name) or
otherwise include ctx.lookup_class(name) so class bindings shadow sizeof,
alignof, and offsetof consistently. Add a regression test covering a
source-level class named sizeof and verify sizeof<Packet>() does not lower to
Expr::PodLayoutSizeOf.

Re-evaluated exact head 021d79b. The two blockers from my prior review are fixed, but merge is still blocked on two independently reproduced source-level issues:
-
crates/perry-api-manifest/src/entries.rs adds perry/native to NATIVE_MODULES and RUNTIME_ONLY_MODULES without adding any API_MANIFEST entries. That violates the native-module strict-surface invariant and leaves namespace calls to undeclared exports permissive even under strict-unimplemented mode. The full local HIR sweep fails exactly on this semantic gap:
- every_supported_module_rejects_bogus_member: perry/native has no entries
- every_supported_module_rejects_bogus_call: a bogus namespace call does not error
Please enumerate the public value exports in the manifest, or add an equivalent explicit strict gate, and retain a perry/native regression.
-
crates/perry-hir/src/lower/expr_call/intrinsics/native_arena.rs:10-14 does not treat class bindings as shadowing the unqualified sizeof, alignof, and offsetof legacy globals. A direct fixture declaring class sizeof and then calling sizeof() lowers successfully to PodLayoutSizeOf. The printed HIR contains the user class plus args: [PodLayoutSizeOf { ... }], proving the user call was silently replaced. shadows_unqualified_global already includes lookup_class; please use that boundary and add a class-shadow regression (ideally covering all three helpers).
Positive evidence on this exact head: the hoisted perry/native alias regression passes; immutable PodView alias length uses js_native_pod_view_length; native_arena HIR integration is 17/17; codegen lib is 964/964; the POD-manifest subset is 10/10; and the public end-to-end fixture compiles, links, and runs with the expected result. No version bump is needed. I have not merged this head.

Re-audited exact head d85e1c7 independently of CI. The two blockers from my prior review are resolved: perry/native now enumerates every public value export in the manifest and passes the strict unknown-member/call sweeps; POD layout helpers now use the canonical shadows_unqualified_global predicate and the class-shadow regressions lower as ordinary calls. The earlier import-hoisting and immutable PodView alias fixes also remain intact. Independent exact-head validation passed: 38 api-manifest tests, 15 strict-surface tests, 18 native-arena HIR tests, 5 manifest-consistency tests, all 964 codegen unit tests, 9 POD/provenance regressions, 2 native PodView runtime tests, the generated native stub test, the executable native-value-profile fixture, test registration, formatting, generated API docs idempotence, diff checks, and a clean merge-tree against current main. Existing warnings only. No version bump needed. I found no remaining source-level blocker and consider this head mergeable.
