A narrow value-first ordinary-expression path now keeps simple numeric literals, locals, local assignment, and numeric binary ops as `f64`, and simple boolean literals/locals/assignment/comparison/`!` as `i1`, until return/runtime materialization. Broad ordinary expression lowering is still predominantly generic `double` unless a local proof applies. Evidence: `representation_first_numeric_locals_stay_f64_until_abi` and `representation_first_boolean_locals_stay_i1_until_abi`. | +| `[~]` | Keep `JSValue` as ABI/fallback, not optimizer default | Public ABI remains `double`/NaN-box. First ordinary-function, own-instance-method, and local-closure typed-f64/typed-i1 candidates now keep raw `double`/`i1` clones behind public JSValue wrappers that guard arguments, call the typed clone on success, box/materialize at the ABI edge, and fall back to an internal generic body. Own-instance methods now also have a narrow `Int32... -> Int32` bitwise-safe clone: the public method symbol stays a JSValue wrapper/vtable target, exact direct calls guard receiver/method identity and Int32 args, call the internal `i32(...) -> i32` clone, and box only at the method ABI boundary. Ordinary functions also have a first string passthrough clone shape: the internal clone passes raw `StringHeader*` handles as `i64`, the public wrapper guards/unboxes JS strings, boxes the raw result with `js_nanbox_string`, and falls back to the generic body; same-module direct `FuncRef` calls with proven string args can call that raw clone directly after guards. Own-instance string passthrough methods now use the same raw `i64` string clone shape behind the public JSValue method wrapper, and exact direct method calls guard receiver/method identity plus string args before boxing only at the call boundary. Local typed string closures now use the same closure-aware raw string ABI (`i64 %this_closure, i64 string args... -> i64 string`) behind a public JSValue wrapper and guarded direct local call path, including immutable string captures guarded at wrapper/direct-call boundaries. Local typed closure clones now use a closure-aware internal ABI (`i64 %this_closure, typed args...`) and accept immutable typed captures for the conservative numeric/i32/boolean/string slices. Ordinary functions now also cover mixed native predicate shapes: `number... -> boolean` emits an internal `i1(double, ...)` clone after `f64` guards, `Int32... -> boolean` emits an internal `i1(i32, ...)` clone after finite/in-range integer guards, and straight-line `Int32... -> Int32` bitwise bodies emit an internal `i32(...) -> i32` clone that boxes only at public/direct-call ABI edges. Same-module direct `FuncRef` calls carry typed parameter reps and can call those clones directly after the matching guards. Async, built-in string methods/operators, dynamic string calls, escaping/unknown closures, mutable/boxed/`this`/`new.target` captures, inherited/dynamic method bodies beyond public wrapper dispatch, unsupported typed-string/i32 closure shapes, and most functions/methods still use generic ABI. | +| `[~]` | Use `i64 JSValueBits` internally for boxed values | `JsValueBits` records and selected production consumers exist, including write-barrier child selection, boxed local/parameter/PreallocateBoxes storage as raw `i64` box pointers, compiler-emitted closure capture slots for boxed/generic JSValue traffic as raw `i64` bits, `array.push` slot/runtime-helper value selection, and dynamic property/index-set RHS selection before boxing at the store/helper edge, including array runtime-key index setters. `ExpectedNativeRep::JsValueBits` now tries value-first lowering for ordinary native expressions and direct `f64`/proven-`i1`/integer/native-handle/promise-boundary materialization to boxed bits before falling back through `JSValue`. Public boolean parameters in generic bodies still enter as JSValue ABI locals unless a typed clone owns the call path. Hand-written runtime closure users keep the compatibility `f64` helper API, dynamic property/index helper edges beyond the covered store paths, and many generic expression paths still materialize through `double`. Evidence: `accepts_js_value_bits_materialization_transitions`, `artifact_records_direct_f64_to_js_value_bits_for_write_barrier`, `artifact_records_direct_i1_to_js_value_bits_for_write_barrier`, `artifact_records_write_barrier_child_js_value_bits`, `boxed_local_slot_uses_i64_js_value_bits_until_helper_edges`, `boxed_param_slot_uses_i64_js_value_bits_until_helper_edges`, `boxed_jsvalue_storage_uses_bits_helpers_for_strings_objects_and_tags`, `artifact_records_boxed_local_slot_as_js_value_bits`, `box_bits_roundtrips_non_number_tags_exactly`, `test_closure_capture_bits_roundtrip_tagged_values`, `artifact_records_array_push_value_bits_before_slot_store`, `artifact_records_dynamic_property_set_value_bits_before_helper`, `artifact_records_dynamic_index_set_value_bits_before_helper`, and `artifact_records_array_runtime_key_index_set_value_bits_before_helper`. | +| `[~]` | Rich TypeFacts/effect/range/escape lattice | Array-kind, array-stability, noalias, effect, unknown-call, alias, aggregate identity exposure, materialization-hazard facts, and a first async/microtask escape fact now feed packed-f64 and cached-length proofs. Loop array-length consumers now emit accepted/rejected effect-fact artifacts, including explicit async/microtask rejection records when an `await` would make cached length or bounded-index lowering unsafe. Object facts, field-sensitive escape/range facts, broader async/microtask summaries, and wider consumer coverage remain incomplete. Evidence: `async_microtask_escape_is_tracked_as_effect_fact`, `loop_length_effect_artifact_records_consumed_preservation_fact`, `async_microtask_effect_blocks_length_and_bounds_proofs_with_artifact_reason`, `aggregate_array_identity_exposure_marks_materialization_hazard`, `indirect_array_alias_from_container_blocks_length_and_bounds_proofs`, `loop_local_array_alias_push_blocks_packed_f64_loop_and_artifacts`, `hir_facts` unit tests, and invalidation regressions in `crates/perry-codegen/tests/native_proof_regressions/invalidation.rs`. | +| `[~]` | Late boxing only at true dynamic boundaries | Native fast paths reduce boxing in verified regions; straight-line numeric and boolean ordinary-expression slices now materialize `f64`/`i1` only at return/runtime compatibility boundaries. Ordinary bodies still frequently lower to JSValue/`double` early outside those proven slices. | +| `[~]` | Treat async/generator lowering as allocation lowering | Compiler-private async/generator control locals now avoid generic JSValue boxes for the narrow closure-shared control state: `__gen_state` / `__gen_pending_type` use typed `i32` heap cells, and `__gen_done` / `__gen_executing` use typed boolean heap cells. This preserves closure lifetime/sharing semantics while keeping control reads, writes, and `__gen_state === const` dispatch comparisons in native `i32`/`i1`. The compiler-private iter-result scratch slot now has raw-`f64`, raw-`i32`, and raw-`i1` handoffs for proven numeric, Int32, and boolean payloads: proven numeric payloads store raw, annotation-only numeric payloads coerce through `js_number_coerce` before raw storage, proven Int32 payloads store raw `i32` while annotation-only Int32 values stay off the raw-i32 slot, proven boolean payloads store raw `i1`, annotation-only boolean payloads stay generic, numeric consumers read through `js_iter_result_get_value_f64`, Int32 consumers read through `js_iter_result_get_value_i32`, boolean consumers read through `js_iter_result_get_value_i1`, and runtime side flags prevent GC from scanning raw primitive bits as roots. Public await/PROMISE resolution values, `__gen_sent`, pending values, async captures, and externally visible async boundaries remain JSValue/generic.

Eligible ordinary functions expose the original public symbol as a JSValue trampoline and move the generic implementation to an internal `__generic` body; same-module direct calls can target f64/i32/i1/string clones when their arguments are proven and guarded. Exact own instance methods now use the same public-symbol wrapper shape for the narrower method-eligible boolean/numeric/string slices: runtime vtables register the public JSValue trampoline, typed clones stay internal, numeric-predicate method clones use `i1(double, ...)` or typed-param-rep internal signatures, straight-line `Int32... -> Int32` bitwise method clones use `i32(...) -> i32`, string passthrough method clones use `i64(string...) -> i64 string`, and guarded direct compiled calls jump to the internal generic method body on typed-argument guard failure. Eligible local closures expose the original closure function pointer as a JSValue trampoline, keep the generic closure body under `__generic`, and keep typed clones internal; numeric-predicate closure clones use `i1(i64 closure, typed args...)` internal signatures, and string passthrough closure clones use `i64(i64 closure, i64 string...)` internal signatures with `js_nanbox_string` only at wrapper/direct-call boundaries, and straight-line `Int32... -> Int32` bitwise closure clones use `i32(i64 closure, i32...)` internal signatures with JSValue boxing only at wrapper/direct-call boundaries. Typed closure clones now always receive `i64 %this_closure`; immutable f64/i32/i1/string capture slots are loaded through that handle and converted to native reps before body lowering, with string capture guards emitted before raw clone entry. Built-in string methods/operators, dynamic string call sites, unsupported string method bodies, mutable captures, boxed captures, `this`/`new.target` captures, dynamic closure values, unsupported typed-i32 closure shapes and escaping/async closure shapes remain generic.

Store-bearing shapes such as `arr[i] = arr[i] + number` and `arr[i] = Math.abs(arr[i])` now side-exit to the slow clone on store-guard failure instead of rejoining after boxed fallback; the unary math shape lowers the fast RHS to native `llvm.fabs.f64` only when the operand is the proven packed element, while coercive operands stay generic. `Int32[]` loops now have a packed-i32 versioning slice: read loops use the i32-specific layout guard, label fast/slow clones and artifacts as `packed_i32`, and materialize `arr[i]` as native `i32` inside the fast clone from the guarded raw numeric slot; a first store-bearing shape, `arr[i] = (arr[i] + i32_const) | 0`, keeps the RHS in the i32 lane, stores the exact f64 raw numeric slot after the packed-i32 store guard, and side-exits to the slow clone on guard failure. Release symbol guard coverage now roots/asserts the generated typed-feedback array helpers (`packed_f64_array_loop_guard`, `packed_i32_array_loop_guard`, numeric get/set guards, boxed fallbacks, numeric push, and companion array feedback helpers) so stale LTO/static archives fail before link. Dynamic fractional index fallback evidence now covers preserving the original runtime key for get/set and not truncating typed-array fractional numeric keys. Local alias mutation, length writes, unknown calls, materialization hazards, unsafe f64 stores to Int32 arrays, and unsafe store-then-read shapes still invalidate or reject the relevant cached-length/bounds/packed numeric proofs. Broader effect summaries remain incomplete.

Numeric consumers now use a raw-f64 class-field get path that keeps the guarded fast load as native `f64` and coerces only the boxed runtime fallback before the numeric merge. Raw numeric class-field get/set artifacts now carry explicit exact-declared-receiver, guarded class-id/keys, raw-f64 slot-array, and pointer-free bitmap notes; raw numeric stores also emit `WriteBarrierElided` evidence because the slot is proven non-pointer. Unknown receivers and computed/dynamic-shape class bodies do not claim raw slot access in their source function. General fixed mixed layouts and runtime pointer bitmaps are not complete. Evidence: `typed_feedback_guards_direct_class_field_specialization`, `artifact_records_raw_numeric_class_field_f64_fast_paths_and_fallback_reasons`, and `raw_numeric_class_field_rejects_unknown_or_dynamic_shape_receiver`. | +| `[~]` | Method/effect summaries for scalar replacement across simple method calls | Exact-receiver summaries exist for scalar-replaced class instances whose own method is fixed-arity and synchronous with either a numeric `return` over public numeric `this.field` reads/numeric params/arithmetic, a boolean comparison predicate over that same numeric subset, or a signed Int32 bitwise return over public Int32 fields/params/in-range literals. This lets `new Point(...).sum()` / `isAbove(n)` and narrow `new Flags(...).mix(i32)`-style calls inline against scalar field slots without heap allocation or method dispatch when arguments are proven in the current expression. Public `number`/`Int32` local arguments, plus arithmetic expressions over guarded numeric locals and literals, now use guarded fast paths: f64 summaries check `js_typed_f64_arg_guard`, Int32 bitwise summaries check `js_typed_i32_arg_guard`, and fallbacks materialize the scalar receiver before generic by-ID method dispatch. Schema-v15 artifacts give `scalar_method_summary` facts a structured `detail` field, so inline records distinguish `exact_receiver_summary` versus `guarded_numeric_args_fast_path`, while materialized fallbacks distinguish `generic_argument` versus `guarded_numeric_args_fallback`. Unproven `any` arguments/expressions, unsigned shifts, non-Int32 fields for Int32 summaries, and broader method shapes stay generic. Mutation/effect summaries, inherited/dynamic methods, field writes, `this` escape, accessors, dynamic property reads, nested/unknown calls, and broader non-numeric methods remain open. Evidence: `scalar_replaced_simple_method_call_inlines_summary_without_dispatch`, `artifact_records_scalar_replaced_method_summary_inline`, `scalar_replaced_boolean_method_predicate_inlines_without_dispatch_or_allocation`, `artifact_records_scalar_replaced_boolean_method_predicate_inline`, `scalar_replaced_int32_bitwise_method_inlines_without_dispatch_or_allocation`, `scalar_method_int32_bitwise_guards_public_int32_argument_and_preserves_fallback`, `scalar_method_int32_bitwise_rejects_unproven_or_unsigned_shapes`, `scalar_method_boolean_predicate_rejects_mutation_call_accessor_and_dynamic_property`, `scalar_method_boolean_predicate_rejects_unproven_numeric_arguments`, `scalar_method_boolean_predicate_rejects_unproven_numeric_argument_expressions`, `scalar_method_boolean_predicate_guards_public_numeric_arguments`, and `scalar_method_boolean_predicate_guards_public_numeric_argument_expressions`. | +| `[~]` | Interned property/method ID dispatch for hot static names | A first compatibility ID layer routes selected generated static-name property get/set, method fallback/apply, typed-feedback method-call, and class-method bind callsites through `*_by_property_id` / `*_by_id` wrappers. The current ID representation is the interned heap `StringHeader` pointer emitted by the StringPool, preserving existing semantics while removing raw byte-pointer/length plumbing from those callsites. Full global numeric IDs, vtable/property maps keyed directly by IDs, dynamic/computed keys, JS bridge calls, and broad specialized paths remain open. Evidence: `static_property_access_on_computed_class_uses_property_id_wrappers`, `static_name_method_fallback_uses_method_id_wrapper`, `static_name_spread_method_fallback_uses_method_id_wrapper`, and `static_name_class_method_value_uses_method_id_bind_wrapper`. | +| `[~]` | Unified safe string-like lowering | A first `PerryStringRef` resolver normalizes raw interned `StringHeader*` IDs, boxed heap-string IDs, and boxed SSO short-string IDs for the by-ID property/method wrappers. The typed-string function, own-instance-method, and local-closure ABIs add a non-throwing string-only guard/unbox pair for JS string arguments and immutable string captures, and materialize SSO strings only after the guard. These still use raw `StringHeader*` handles for the internal clone, not a full end-to-end `PerryStringRef` value representation; built-in string methods/operators, mutable string captures, dynamic receivers, unsupported string method bodies, and dynamic/computed lowering sites remain generic. Evidence: `dispatch_id_resolver_accepts_raw_heap_and_sso_string_forms`, `typed_string_arg_guard_is_non_throwing_and_string_only`, `typed_string_function_clone_emits_internal_clone_and_guarded_wrapper`, `artifact_records_typed_string_direct_call_selection`, `typed_string_method_clone_emits_internal_clone_and_guarded_direct_call`, `artifact_records_typed_string_method_clone_selection`, `typed_string_closure_clone_emits_internal_clone_and_guarded_direct_call`, `typed_string_closure_clone_accepts_immutable_string_capture`, and `artifact_records_typed_string_closure_clone_selection`. | +| `[~]` | Key-specialized Map/Set lowering | Runtime Map/Set side tables index numeric and string-content keys. Codegen now lowers proven `Map.set/get/has/delete` and `Set.add/has/delete` through string-key helpers, with typed Map value helpers for proven `number`/`Int32`/`PerryU32`/`PerryF32`/`boolean`/`string` set values and typed Set value helpers for proven `Int32`/`PerryU32`/`PerryF32`/`boolean`. It also lowers proven `Map.set/get/has/delete` through guarded raw-f64 key helpers (`js_map_*_number_key`) and proven `Set.add/has/delete` through guarded raw-f64 value helpers (`js_set_*_number`); guard failure and unproven values branch to the generic JSValue helpers. Helpers are rooted for release/LTO and covered by the runtime symbol guard. Native-rep artifacts record selected collection lanes with consumed type facts (`string_ref`, `f64`, `i32`, `u32`, `f32`, or `i1`) and rejected/generic lanes with rejected collection facts. Annotation-only typed values remain generic. Unboxed stored values beyond helper boundaries, dynamic receivers, and broader `Record`/dictionary lowering remain incomplete.

The report now includes explicit reason maps and evidence rows for typed-path selected/fallback/rejected decisions, typed-clone selected/rejected/not-recorded decisions, generic fallbacks, dynamic boundaries, boxes, unboxes/coercions, runtime property gets, direct field loads, scalar replacement selected/fallback/rejected decisions, bounds kept/eliminated, barriers emitted/eliminated, and selected/rejected collection helper lanes, including string-key Map/Set helpers, numeric Map/Set helpers, and typed-value Map/Set helpers. Evidence rows now carry consumed/rejected fact labels so selected and rejected typed paths are artifact-backed instead of note-only. Native-rep artifact summaries include consumed/rejected fact-kind counts and typed-path decision counts, and the verifier rejects malformed fact-use rows. Explain-lowering mode requests comprehensive typed-clone rejection records from codegen, including broad clone-family mismatches that default native-rep artifact runs suppress for noise control. A bounded non-clone completeness slice now derives concrete categories for scalar-replaced raw-f64 direct field loads, structured scalar-method summary details, generic write-barrier child-bit emissions, checked-native bounds records that lack an explicit `bounds_state`, collection helper selected/rejected decisions from artifact notes such as `selected_helper`, `generic_helper`, and `typed_collection_rejected`, and collection typed-value selected/rejected decisions from consumed/rejected `map.*_value_helper` and `set.*_value_helper` facts. Material evidence now reports/gates boxed-number allocations, buffer slow-path helpers, array slow-path helpers, traced allocations, write barriers, and wall-time speedups in the native ABI packet.

It is not yet a general typed function, method, or +closure ABI. Public user function, method, and closure entry points still use +the generic `double`/NaN-box ABI for parameters and returns. Eligible ordinary +typed-f64/typed-i1 functions now expose that public ABI through a wrapper under +the original symbol, with an internal typed clone plus an internal generic body +fallback. The typed-i1 ordinary-function path includes first mixed native +signatures for numeric predicates: an internal `i1(double, ...)` clone is called +from the public JSValue wrapper after numeric guards, and an internal +`i1(i32, ...)` clone is called for `Int32` predicates after non-throwing +finite/in-range integer guards. Same-module direct `FuncRef` calls now carry +typed parameter reps so they can guard/unbox `f64` or `i32` arguments and call +those clones directly while keeping a generic body fallback. +The ordinary-function path also has a first typed-i32 return slice for +fixed-arity `Int32` parameters and straight-line bitwise-preserving `Int32` +bodies. Its internal clone uses raw `i32` parameters and an `i32` return, while +the public wrapper and same-module direct call path guard/unbox arguments and +box the raw result only at the JSValue ABI boundary. +A first typed-string ordinary-function path accepts fixed-arity string +parameters and a string passthrough return; its internal clone takes and returns +raw `StringHeader*` handles as `i64`, while the public wrapper guards/unboxes +JS string arguments, boxes the raw result with `js_nanbox_string`, and falls +back to the internal generic body on guard failure. Same-module direct +`FuncRef` calls with proven string arguments can guard/unbox and call the raw +string clone directly, boxing only at the call boundary. +Eligible own-instance methods use the same shape: the original method +symbol is a JSValue wrapper registered in runtime vtables, and the generic +method body moves to an internal `__generic` symbol. A narrow set of direct +compiled calls may still branch to the same internal typed-f64 or typed-i1 +function/method clones after guards pass, and those direct-call guard failures +target the generic body instead of re-entering the public wrapper. Eligible +local closures use the same wrapper/body split: the stored closure function +pointer remains the original public symbol, the generic closure body moves to +`__generic`, and internal raw-`double`/`i1` clones are called from the public +wrapper or guarded direct local closure call sites. Those typed closure clones +now take `i64 %this_closure` as their first internal parameter and can load +immutable typed capture slots as native f64/i1 values. The new native facts are +collected for module init, function, method, static-method, and closure bodies, +then consumed inside those bodies where a specific proof exists. + +Compiler evidence for this branch covers: + +- region-local integer facts (`i32`/`u32`), boolean facts (`i1`), and selected + JS-number native reps; +- Buffer/Uint8Array `BufferView`/`U8` fast paths with explicit bounds and alias + proof records; +- packed-`f64` array loop versioning guarded by typed-feedback/runtime layout + checks, including the first safe store-update path whose store-guard failure + side-exits/restarts in the slow clone instead of rejoining the raw fast clone. + A narrow unary-math store RHS, `Math.abs(arr[i])`, also stays native in the + fast clone as `llvm.fabs.f64` when the operand is the proven packed element, + while coercive unary math operands remain on the generic ToNumber-preserving + slow path. `Int32[]` loop slices now distinguish `packed_i32` array facts, + emit `for.packed_i32_fast`/slow clones, materialize `arr[i]` as native `i32` + inside read fast clones, and cover the first i32-preserving store update + shape with slow-clone side exits on store-guard failure while preserving + generic fallback and alias invalidation evidence; +- a narrow representation-first ordinary-expression path for simple numeric + literals, locals, local assignment, and numeric binary ops, plus simple + boolean literals, locals, local assignment, numeric/boolean comparisons, and + unary `!`.
