The four FFI symbols and the surrounding ReadableStream / WritableStream / TransformStream / reader / writer / `pipeTo` / `pipeThrough` surface are all already implemented in `crates/perry-stdlib/src/streams.rs` (38 `#[no_mangle]` extern "C" entries, 1300+ lines; registered via `pub mod streams; pub use streams::*;` at `crates/perry-stdlib/src/lib.rs:80,82`) — landed in #237/#301 (PR #301 merged 2026-04-29 17:44 UTC, ~9h before #320 was filed and three on-main commits ahead of the v0.5.405 cut available at the time of writing; the issue reporter likely missed that #237 had just merged during the same #309/#310 sweep). The codegen side at `crates/perry-codegen/src/lower_call.rs:3469-3584` already wires all 14 dispatch sites for `js_readable_stream_*` (`get_reader`, `cancel`, `tee`, `pipe_to`, `pipe_through`, `locked`, `controller_enqueue`, `controller_close`, `controller_error`, `controller_desired_size`) and `crates/perry-codegen/src/runtime_decls.rs:966-993` declares all 12 LLVM externs. Verified the issue's literal minimal repro on `main` HEAD: `new ReadableStream({ start(controller) { controller.enqueue("hello"); controller.close(); } }); console.log(stream)` compiles cleanly, links cleanly, runs to exit 0 — no `Undefined symbols` error. The cosmetic `console.log(stream)` rendering still shows `1` (raw registry-id-as-f64 handle) instead of Node's `ReadableStream { locked: false, state: 'readable', supportsBYOB: false }` — but this is a generic console-formatter dispatch limitation across all handle-based registries (same `id as f64` pattern used by `BLOB_REGISTRY`, `FETCH_RESPONSES`, `READERS`, `WRITERS`, `TRANSFORM_STREAMS`), not a stream implementation gap. Stream handles cast to f64 are bit-indistinguishable from numeric values, so console.log can't dispatch on them without either NaN-boxing every handle as POINTER_TAG (breaks all existing `as usize` extraction sites in `lower_call.rs`) or threading static-type info through console.log lowering (multi-day codegen change). Out of scope for #320, which documents the link error specifically — the link error is gone. **All four "adjacent gaps" listed in #320's body are also already covered by #237/#301**: `WritableStream` + writer surface, `TransformStream`, `ReadableStreamDefaultReader` via `js_readable_stream_get_reader` + `js_reader_*` (read / cancel / release_lock / closed_promise), `ReadableStreamDefaultController` exposed implicitly as the stream handle itself per the inline comment at `streams.rs:411` ("the new stream's controller is the stream handle itself"), `pipeTo` at `streams.rs:812`, `pipeThrough` at `streams.rs:891`, `Response.body` wired via `alloc_readable_from_bytes` at `streams.rs:435` (called from the fetch path's response wrapper). New regression test `test-files/test_issue_320_readable_stream.ts` pins the issue's exact code shape (string-chunk `controller.enqueue("hello")` — distinct from the existing #237 tests which all use `Uint8Array` chunks: `_streams_blob` exercises `blob.stream()` over byte buffers, `_streams_pipe` exercises `pipeTo` / `pipeThrough` / `tee` chains, `_streams_user_source` exercises `controller.enqueue(new Uint8Array([...]))` not strings) — matches `node --experimental-strip-types` byte-for-byte for `r1/r2/r3.{done,value}`. **Verification**: cargo build --release -p perry-runtime -p perry-stdlib -p perry clean; gap tests 27/28 = baseline (lone fail is the pre-existing `console_methods` ci-env quirk); all 3 existing #237 stream regression tests still match Node byte-for-byte (no regression from the #320 pin); new `test_issue_320_readable_stream.ts` matches Node byte-for-byte on first run.

Effect declares same-named classes across modules — e.g. `class Base extends Class` inside Data.ts's `TaggedClass` IIFE, plus `class Class extends Base` in Effectable.ts. When the cross-module-import resolver pulls every exported class into Data.ts's `imported_class_stubs` (the v0.5.362 #240 augmentation fires whenever a module references an unresolved type name — the kind Effect generates by the dozen via `arguments`-based `dual()` helpers and bare `A`/`B`/`E1`/`R1` generics), the stub for `Class` carries `parent_name = "Base"` from Effectable's source. In Data.ts's importing namespace, that `"Base"` resolves to Data.ts's OWN local `Base` (different class, same name), whose `extends_name = "Class"` resolves to the imported stub: ⟶ `Base → Class → Base → Class → …` cycle. Every chain-walking site in codegen (and there are ~30 of them: `apply_field_initializers_recursive`, `class_field_global_index`, `static_type_of`'s `PropertyGet` arm, the `class_keys_init_data` parent walk, `receiver_class_name`, etc.) assumed acyclic inheritance. Specifically `apply_field_initializers_recursive` accumulated visited names into `chain: Vec` without bound — that's where the 34 GB RSS came from: a `String` for every cycle iteration on every field-init application call, in a tight `while let Some(c) = cur` loop. Other chain walkers that count rather than accumulate would CPU-hang at constant memory but make zero progress. **Fix is one centralized cycle break in `compile_module`** at `crates/perry-codegen/src/codegen.rs:435+` — runs ONCE after `imported_class_stubs` are built but BEFORE they're added to `class_table`. For each stub, walk the (local ∪ stub) parent chain via DFS in the union name space (preferring local hir.classes over stubs, matching the downstream `class_table.entry().or_insert()` semantics), tracking visited names in a HashSet and capping depth at 64. If the walk revisits a name OR exceeds the cap, the stub is part of a cycle: drop its `extends_name` to `None`, breaking the cycle at the imported side (the local class is left untouched since we can't mutate `hir.classes`). Subsequent chain walks in `apply_field_initializers_recursive`, `class_field_global_index`, `static_type_of`, etc. now operate on a guaranteed-acyclic graph. The fundamental name-collision issue (Data.ts's local `Base` and Effectable.ts's `Base` are different classes despite sharing a name) is left unfixed — a proper resolution requires module-prefixing class names in HIR (e.g. `Base$node_modules_effect_src_Data_ts$TaggedClass` instead of bare `Base`), which is a multi-day refactor with breaking implications for the entire dispatch / `instanceof` / class-id machinery; the cycle break here is purely defensive and lets compilation proceed even when name collisions occur. **Verified end-to-end** on the issue's exact Effect 3.21.2 repro: `cd ~/projects/effect-oom-test && /usr/bin/time -l perry compile test_direct.ts -o /tmp/effect-out` — pre-fix 430s wall / 34 GB RSS / SIGKILL exit 137; post-fix **2.72s wall / 133 MB max RSS / 123 MB peak memory footprint** — a **256× memory reduction and 158× faster wall time**.

Loop then read `.length` on a raw Map handle (returns 0) and produced no iterations. Same root cause as #302, two more missing arms. **Fix** in both for-of lowering sites (`crates/perry-hir/src/lower.rs:5417` and `crates/perry-hir/src/lower_decl.rs:3676`): widen the `Member` arm so when `m.obj` is anything other than `This`, infer the receiver's type via `crate::lower_types::infer_type_from_expr` and dispatch on the result — `Type::Object(ot)` looks the property up via `ot.properties.get(prop).map(|pi| pi.ty.clone())` (covers `const obj = { m }; for-of obj.m`); `Type::Named(cls)` consults the same `class_field_types` registry the `this.` arm uses (covers `const ex = new Example(); for-of ex.m` where `Example`'s `m: Map` is a declared class field — already populated by the v0.5.388 early-pass `register_class_field_types`). New regression test `test-files/test_issue_311_object_property_for_of.ts` (9 cases — Map / Set / Array shorthand `{ m }`, KeyValue `{ items: m2 }`, nested wrapper with renamed property, #302 local-Map regression guard, plus class-instance Map / Set / Array fields) matches `node --experimental-strip-types` byte-for-byte.

Pre-fix `await response.blob()` returned a metadata-only stub `{size, type}` and silently dropped `resp.body`. Three-part fix mirroring #232 / #227: (1) `crates/perry-stdlib/src/fetch.rs` adds `BlobData` + `BLOB_REGISTRY` + `alloc_blob` (mirrors `HEADERS_REGISTRY` / `alloc_headers`); `js_response_blob` rewritten to clone body bytes + content-type into a fresh `BlobData` and resolve with the numeric handle. 6 new FFIs: `js_blob_size`, `js_blob_type` (returns `*StringHeader`), `js_blob_array_buffer` (real `BufferHeader` via `buffer_alloc` — same shape as `js_response_array_buffer`), `js_blob_bytes` (alias), `js_blob_text` (UTF-8 lossy decode = WHATWG replacement-character semantics), `js_blob_slice` with `f64::NAN` sentinels for missing numeric args, null `type_ptr` to inherit, negative-index normalisation per spec. (2) `crates/perry-hir/src/destructuring.rs` two new `lower_var_decl` arms next to the Response.clone() propagation: `const blob = await .blob()` (Response→Blob) and `const b2 = .slice(...)` (Blob→Blob for chained slicing). (3) `crates/perry-codegen/src/lower_call.rs` + `runtime_decls.rs` new `if module == "blob"` arm with size/type/arrayBuffer/bytes/text/slice dispatch. New regression `test-files/test_issue_234_blob_methods.ts` (11 cases — size, text, arrayBuffer + Uint8Array roundtrip, bytes alias, multi-byte UTF-8 + Buffer.from roundtrip, slice with various arg shapes, empty body, negative indices) — all byte-for-byte against `node --experimental-strip-types`. Added to `SKIP_TESTS` in `.github/workflows/test.yml` (compile-smoke step) and `test-parity/known_failures.json` as `ci-env` — same documented macOS-14 SDK/linker pattern as `test_gap_buffer_ops` / `test_buffer_small_alloc` / `test_issue_227_array_buffer_bytes` / `test_gap_fetch_response`. **Maintainer fold-in (v0.5.359 vs PR's 0.5.356 base)**: bumped version above origin's parallel-track v0.5.357 (#233) + v0.5.358 (#235); plus two correctness/cleanup fixes on top of TheHypnoo's PR commits — (a) `js_blob_slice`'s `type_ptr.is_null()` branch now defaults to `String::new()` instead of inheriting the original blob's content-type. Per WHATWG Blob spec / MDN: when `contentType` is absent, the new blob's type is the empty string. Caught by edge-case audit (`new Blob([...], {type: "image/png"}).slice(0, 1).type` is `""` in Node, was `"image/png"` in the original PR); same fix to the inner `string_from_header(...).unwrap_or(...)` decode-failure fallback. (b) Collapsed the duplicate comment block in `lower_call.rs::"slice"` arm (lines 3188-3194 of the original PR restated the same NaN-sentinel rationale twice). `blob.stream()` deferred to #237 (Web Streams API needed project-wide before scoping a Blob-only stub).

The caller's `samples` stayed pointing at the OLD 16-cap ArrayHeader while every subsequent push operated on a separate orphaned new array. **Fix**: install a forwarding pointer at the OLD location on every grow, reusing the GC's existing `GC_FLAG_FORWARDED` mechanism (originally for the copying evacuation pass). `crates/perry-runtime/src/array.rs::js_array_grow` now calls `set_forwarding_address(old_header, new_ptr)` after the copy — the OLD payload's first 8 bytes (length+capacity) become the forwarding pointer, and the gc_flags byte gets the FORWARDED bit (0x80). Every array-pointer reader follows the chain: (1) `clean_arr_ptr` walks the FORWARDED chain (cap depth 64 against cycles) before the LAZY_ARRAY check and the length/capacity sanity check — without this the corrupt header bytes would either get sanity-rejected or read as ArrayHeader fields. (2) `js_value_length_f64` (in value.rs) detects FORWARDED at the GC header and routes through the array-cleaner to follow the chain. (3) Three inline IndexGet codegen fast paths (bounded-loop + general + Object-with-numeric-keys) now read GcHeader byte 1 (gc_flags), AND with 0x80, and route to the `js_array_get_f64` slow path when FORWARDED — same pattern as the existing LAZY_ARRAY guard. (4) `lower_index_set_fast` adds a FORWARDED branch routing through `js_array_set_f64_extend` so writes via stale pointers update the live new array. (5) `trace_array` in gc.rs detects FORWARDED arrays and pushes the forwarding target on the worklist so the live new array stays marked. (6) `rewrite_array_fields` skips FORWARDED arrays since their first 8 bytes hold a pointer not length+capacity. New regression test `test-files/test_issue_233_async_array_param_push.ts` covers number/string/object array element types, nested async wrappers, post-push slice/indexOf/iteration, and IndexSet via stale pointers — all byte-for-byte against `node --experimental-strip-types`. Gap tests 25/28 = baseline (the 3 failing — `array_methods` / `console_methods` / `typed_arrays` — pre-existing TypedArray-related categorical gaps unrelated to this change).

Zod v4 (and any user code) does `const F = Function` to keep + the global `Function` constructor reachable. `perry-hir` did + not recognise that as a `Function` alias, so `new F(...)` + degraded to a user-class `new` and lost the dyn-eval route. +3. `globalThis.Function = ` style aliases (also a real + pattern, e.g. `globalThis.Function = Function`) were not + tracked into the prototype-alias map, so the + `is_global_this_value` branch in `alias_tracking.rs` would + mis-classify the access. + +Each is a small, isolated change. None alters the bucket-3 +(`Deferred`) path that already works. + +#### What changes + +- **`crates/perry-hir/src/eval_classifier.rs`** — add + `KNOWN_CODEGEN_SITE_COUNT` (an `AtomicUsize` sibling of the + deferred-style sink) and a `has_known_codegen_sites()` accessor. + `check_site` increments the counter on every + `EvalBucket::KnownLibraryCodegen` site, mirroring the + `record_deferred_aot_site` pattern. +- **`crates/perry-hir/src/lower/expr_new.rs`** — before the + shadowed-by-user-binding check, ask + `ctx.resolve_class_alias(&class_name)` whether the callee + resolves to `"Function"`. If so, route through the + `Function`-intrinsic path.

No new Perry patches were required to extend from 2 +tools to 11 — the five above are sufficient. + +The series is deliberately scoped so it can be reverted without +leaving dead code: every change is additive, every new symbol +is re-exported from the same `pub use` block, and the +`cross_features` gate in `freshness.rs` is a pure superset of +the prior `has_deferred_dynamic_code_sites()` check. + +#### Known limitation, not addressed + +A separate `RangeError: toString() radix argument must be +between 2 and 36` GC crash on the *full* `context-mode/server.ts` +(4948 lines) is **not** fixed by this PR.
