… baseline 990->983 enumeration.rs was at 14 bare get_raw_*_ptr reads against its ceiling of 5 after #8269 merged, turning `lint` (and so pr-gate) red on main for every rebased PR. The reads were handle-rooted and correct; the conversion to with_{mut,const}_ptr is behaviorally identical and audit-visible. Baseline locked down to 983 per the ratchet's own "debt fell" prompt.

…n identity — pi boot threw Cyclic __proto__
perry-compiled pi (13MB esbuild bundle) died at startup with
`TypeError: Cyclic __proto__ value` out of `js_object_set_prototype_of`,
with obj_bits == proto_bits exactly — the two ARGUMENTS were the same
pointer — while the chain behind the proto was healthy. None of the
bundle's 17 textual `Object.setPrototypeOf(` sites fired a JS logging
shim, because the self-set was manufactured upstream of the call: the
closure-literal singleton caches handed back ONE ClosureHeader for two
evaluations of the same function literal, so `setPrototypeOf(wrapped,
original)` (a graceful-fs-style wrap pattern) received one object twice
and correctly refused the "cycle".
Mechanism: `expr/closure.rs` routed closure literals through
`js_closure_alloc_singleton` (captureless arrows) and
`js_closure_alloc_with_captures_singleton` (arrows with captures, and
non-arrow literals whose captures are all boxes) keyed by
(func_ptr, capture bits). Two evaluations of the same literal with
bit-identical captures — e.g. an arrow capturing the same constant, or
any captureless arrow — came back `===`-equal. ECMA-262
OrdinaryFunctionCreate requires a fresh object per evaluation, and the
distinction is observable through `===`, expando properties, WeakMap
keys, addEventListener de-duplication, and `Object.setPrototypeOf`.
Minimal repros (byte-compared against node before/after):
function mk() { return () => K; } // captured arrow
const a = mk(), b = mk(); // perry: a === b (node: false)
Object.setPrototypeOf(a, b); // perry threw Cyclic __proto__
and the same with `() => 1` (captureless). Both now match node.
Fix: gate every closure.rs literal singleton path on
`is_plain_async_step_body` — the file's existing detector for the
compiler-synthesized plain-async step closures (their terminal
`Stmt::ReleaseBoxes` arms cannot appear in user code). Those are the
closures the caches were built for (PerryTS#8269's parallel async-await
pattern re-creates them per resume with the same per-activation box
captures, and their identity never escapes the promise machinery), and
they keep the fast path. Every user-authored arrow and function
expression now mints a fresh closure. Runtime-internal singleton users
(function-declaration references, property_get/i18n/arrays wrapper
thunks) are separate paths and unchanged. A genuine
`setPrototypeOf(x, x)` still throws — the cycle check is untouched.
Perf note: this deliberately gives back the user-arrow closure reuse
from the PerryTS#8269/PerryTS#8291 captured-singleton extension (e.g. ECS
`World.executeEntityCommands`' per-call inner arrow) and the captureless
user-arrow singleton at literal sites; a sound replacement needs
escape-aware caching rather than identity-violating sharing.
Validation: repros above and test-files/
test_gap_9090_closure_literal_identity.ts byte-identical to node;
`cargo test -p perry-runtime --lib -- --test-threads=1` green — 2813
passed, 0 failed with `--skip reserved_floor` (that module's at-scale
tests SIGABRT on this pre-PerryTS#9110 base; known PerryTS#9108/PerryTS#9110, unrelated);
`cargo test -p perry-codegen`: 283+75 passed after updating the four
native_proof_regressions pins from `js_closure_alloc_singleton` to
`js_closure_alloc` (their real subject — the alloc storing the public
wrapper pointer — is preserved); one pre-existing env-leak flake
(`packed_f64_loop_unary_math_store_versions_with_side_exit`) passes in
isolation.

…ity — pi boots (#9128) * fix(runtime): closure-literal singleton caches conflated user function identity — pi boot threw Cyclic __proto__ perry-compiled pi (13MB esbuild bundle) died at startup with `TypeError: Cyclic __proto__ value` out of `js_object_set_prototype_of`, with obj_bits == proto_bits exactly — the two ARGUMENTS were the same pointer — while the chain behind the proto was healthy.

Claude-Session: https://claude.ai/code/session_01Ay8VyLkKbm8Hkc1xmvTEsP * fix(runtime): name-keyed builtin-member reads must see user overrides — pi boot threw Cyclic __proto__ (part 2) With the closure-literal identity fix in place, pi still died at startup with `TypeError: Cyclic __proto__ value`, obj_bits == proto_bits exactly. The instrumented throw site showed both arguments were ONE closure with `func_ptr = 0xBADD_DEAD` (BOUND_METHOD_FUNC_PTR, capture_count 3) and a healthy 3-link chain behind it — the canonical bound-native callable that `bound_native_callable_export_value` mints once per (module, member). The failing code is graceful-fs's module init, bundled into pi (pi-bundle.mjs:6621/6686/6705): var chdir = process.chdir; process.chdir = function (d) { ... }; if (Object.setPrototypeOf) Object.setPrototypeOf(process.chdir, chdir); and the same wrap for fs.rename / fs.read. Under perry the patch write did not round-trip on the re-read, so setPrototypeOf received the SAME canonical closure for both arguments — a self-set — and the cycle check correctly refused it. The earlier probe of this exact shape passed because it patched a PLAIN object, where writes round-trip; the failure needs a builtin namespace receiver. The JS shim over `Object.setPrototypeOf(` never fired because the conflation happens in the native member-READ, upstream of the call. Root cause: user writes to builtin namespace members are stored in two different places depending on the lowering — computed stores (`process[k] = fn`) go through `nm_field_set_override` into `NATIVE_NAMESPACE_PROP_OVERRIDES`, while static stores (`process.chdir = fn`) reach the generic store path and land as an own dynamic field on the canonical namespace object. The NAME-KEYED read entries carry no object pointer and consulted only the override table: * `js_native_module_property_by_name` (codegen static reads of process.* members) missed own-field stores, so the graceful-fs static patch was invisible to the static re-read; * `js_native_module_esm_export_value` (codegen property reads off a builtin DEFAULT import — `import fs from "node:fs"; fs.rename`) consulted NOTHING (consult_overrides=false plus its own snapshot cache), so no fs patch was ever visible. In Node the default import of a core module is the live mutable CJS exports object, so the patched value must win; the tls DEFAULT_* cache-coherence hack was the ad-hoc version of this for three keys. Fix: `native_namespace_user_value(module, prop)` consults the override table and then the canonical namespace object's own field (never creating a namespace — if none exists, no user store can have landed on one). Both name-keyed read entries call it before any built-in resolution or snapshot cache. Named ESM import bindings of core modules snapshot at module init before user patches run, so their intended snapshot semantics are unaffected in the eager case. Validation: r11-r16 probe matrix (process/fs, static/computed reads and writes) and test-files/test_gap_9091_native_member_patch_roundtrip.ts byte-identical to node; a genuine `setPrototypeOf(x, x)` still throws.

native_module_enumis correctly rooted (RuntimeHandleScope, per-iteration scopes) but reads its handles through bareget_raw_*_ptr— 9 new sites, pushingobject/field_get_set/enumeration.rsto 14 against its per-module ceiling of 5 in the raw-handle debt ratchet.Fix: convert all nine to the #7341 blessed
