compatible alternate integer widths, wide constant references, manual BigInt i32::MIN, Float64 bit patterns, minimal or nonminimal BigInt payloads, atom or constant-pool string encodings, and synthesized seven-op unary chains for neg, plus, dec, inc, bitnot, lnot, and typeof; exact fresh-runtime tags, values, UTF-16 units, Float64 bits including negative zero and NaN payload/sign, Int and BigInt boundary promotion, the pinned 2026-06-04 heap BigInt decrement unsigned-opcode quirk, Number bitnot ToInt32, String arithmetic ToNumeric, execution-time BigInt unary-plus TypeError, scalar truthiness, identity or canonical rewrite evaluation, admitted double-neg and mixed chains, and non-address String and typeof-atom identity matrices; ordinary-leaf read and write byte identity, selected child metadata including sloppy js_mode, two-entry Float64 constant pool, 46-byte and 38-instruction code, and five conditional and loop branch targets with IR mappings; exact JS_TAG_INT equal and unequal JS_Call results, constructor and own length/name/prototype.constructor identity, JS_CallConstructor instance prototype and instanceof, sloppy caller/arguments undefined, strict child-js_mode read/write identity with caller/arguments TypeError, and evaluated-closure serialization rejection; explicit outside-frontier Private and Symbol atom cases, including unary Symbol truthiness and typeof boundaries; and malformed ULEB, atom, string, bytecode length, ArrayBuffer, and TypedArray read diagnostics; data-driven ordinary expansion evidence for the 57-row atom-free and five-row plain-call admission cohorts, with seven exact compile-only BC5 wires, hashes, parsed and field-verified child metadata and code offsets, opcode sets, fresh-runtime read/write identity and execution; compiler-natural evidence for 45 target rows including Drop raw 14 and Dup raw 17, authenticated manual-wire VM evidence for stack raws 15, 16, and 18 through 32 plus six multi-op lowering sequences and every output slot, explicit unique raw cohorts with an exact manual-missing set, return_undef max_stack zero, exact JS_TAG_BOOL HTMLDDA predicate semantics, undefined plain-call receiver with argc zero through four, the exact 22-result unary and binary sink sequence, and exact BigInt and physical and normalized Float64 tags and payloads; and Stage3A invocation evidence for compiler-natural call_constructor raw 33, call_method raw 36, and array_from raw 38 with exact whole wires and metadata, authenticated property-free manual constructor and method wires plus zero- and three-element array wires, distinct new.target prototype and argument order, strict receiver object identity and argc/order, fresh array identity, full natural admission for raws 33 and 38, and raw 36's blocked get_field2 producer split from its manual public evidence; and Stage3B raw39 apply evidence for compiler-natural magic 0 and 1 whole wires, a compiler-authenticated 53-byte strict three-argument base transformed into four 58-byte property-free manual u16 wires, exact fresh-runtime read/write identity, nullish ordinary-call shortcuts, dense call and construct behavior, raw primitive, ordinary, and callable new.target without prevalidation, callability, build-list, constructor, and construct-only Proxy trap ordering, mechanically executable noncanonical 2 and MAX operands with the Rust unadmitted boundary; and Stage3C tail invocation evidence for compiler-natural raw35 tail_call and raw37 tail_call_method exact wires, parsed metadata and terminal opcode layouts without trailing return, raw37's blocked get_field2 producer split from a compiler-authenticated property-free 62-byte manual wire, fresh-runtime read/write identity, strict undefined plain receiver, exact method receiver and argc/order, noncallable TypeError ordering, thrown callee and getter identity through catch, preserved callee-to-tail backtraces, and upstream InternalError stack overflow proving non-PTC recursion; and Stage3D raw48 throw evidence for the exact compiler-natural strict 45-byte wire and child cf30 code, fresh-runtime read/write identity, terminal no-return behavior, C uncaught exception and JavaScript catch identity for integer, object, and Error values, pending-exception clearing, backtrace attachment before catch, and iterator-close ordering that preserves the original exception; and Stage3E raw49 throw_error evidence for the exact 58-byte compiler-natural strict const-assignment origin, whose lexical local and raw94 remain outside the Rust ordinary cohort, and the exact 47-byte property-free mechanically derived wire with one used atom slot, parsed raw49-only terminal code, 0-to-0 empty-stack semantics, fresh-runtime read/write identity, Unicode TypeError spelling, defining-realm identity, own backtrace, pending-exception publication and clearing, caller-catch no-return behavior, mechanically executable subtype 1 SyntaxError and subtype 255 InternalError with the Rust subtype-0-only admission boundary, and Stage3F raw177 nop evidence for the compiler-natural exact 40-byte strict empty-function raw41-only baseline and its mechanically derived exact 41-byte raw177-plus-raw41 wire, parsed property-free zero-stack metadata with zero atoms and constants, fresh-runtime read/write identity, repeated defining- and caller-realm undefined results without pending exceptions, explicit non-compiler-natural provenance, and the raw177-only malformed wire reserved for the Rust verifier negative boundary and never read or executed by C
