Packages whose declarations name WebAssembly types (quickjs-wasi,
photon-node, and therefore pi) failed scriptc's type check with SC0001
"Cannot find namespace 'WebAssembly'", because scriptc's ES-only type
world never loads lib.dom, so `scriptc coverage` could not analyze them.
- scriptc.d.ts declares lib.dom's WebAssembly namespace and BufferSource
(admitting every ArrayBufferView, so Node's Buffer types fit).
- The type mapper gives every type declared in the namespace, and unions
over one, the checked-dynamic representation, so declarations that only
mention them compile.
- Every reached use of the API value refuses at its site with a named
SC2020 diagnostic: `WebAssembly.<member>` reads and calls,
`new WebAssembly.<Class>`, `instanceof WebAssembly.<Class>`, the bare
namespace, `globalThis.WebAssembly`, and the global object viewed
through a cast to a type with a WebAssembly member (pi codemode's
spelling). TypeScript sources fail the build; JavaScript sources get a
located runtime fence.
- `typeof WebAssembly` and `typeof WebAssembly.<member>` need no value and
fold to Node's answers ("object", "function"), including inside
`typeof x === "..."` tests, so feature probes in JavaScript glue behave
as in Node. Before, a JavaScript probe answered "string" (the identity
token) and silently took the non-wasm branch.
- The surface manifest projects the refusal (stdlib.webassembly), and the
compatibility ledger's `WebAssembly` global row moves from
not-implemented to refused; no other row changes.

Represent ordinary JavaScript arrays with hole, value, and explicit-undefined states; add sparse side storage and carry missing values through the frontend, native backends, runtime, and Node-facing consumers.
- The ratified rename rider (world-unification §7 lane 5): "DOM" collided with the browser DOM and, post-lane-1, the structure is no longer a document tree. Comments and doc prose now say "the checked-dynamic tree" for the noun and "dyn" adjectivally; runtime symbol names (scr_dyn_*), the error.domClone libCall, and the real web DOMException family are unchanged.
- The few user-facing strings carrying the nickname move with it (the structuredClone cyclic message, the dc subscriber/publish fences, two emitter ICE texts); diagnostics snapshots regenerated (96 pass). One private compiler constant (DOM_PROTO_METHOD_NAMES -> DYN_PROTO_METHOD_NAMES) rides along.
- Mechanical sweep, 142 files, comments/prose only — no behavior change.
