## Problem `wrapScopedCompositionScript` wraps composition scripts with scoped `document`, `window`, and `gsap` proxies. The current published `latest` and `alpha` packages still pass the proxy as the `Reflect.get` receiver, so browser host accessors like `document.body` can throw `TypeError: Illegal invocation`. When that happens, the wrapper catches the error and aborts the rest of the composition script. For components that start hidden and reveal themselves through GSAP/timeline setup, that means the timeline is never registered and the render can stay visually empty. Closes #606. ## What this fixes - Reads scoped proxy properties with the original target as the `Reflect.get` receiver. - Applies the same target-receiver pattern to scoped proxy setters, including remapped timeline registry writes. - Preserves the existing behavior of binding returned methods back to the real target. - Covers document, window, remapped timeline registry, GSAP, and GSAP utils accessors/setters in regression tests that throw unless the receiver is the original target. ## Root cause The previous proxy traps called `Reflect.get(target, prop, receiver)`. For accessors, that invokes the getter with `this === receiver`, and in this wrapper the receiver is the proxy. Browser host getters such as `Document.prototype.body` validate their receiver and reject the proxy, which makes ordinary composition code like `document.body` fail before timeline registration can run. ## Verification ### Local checks - Confirmed current npm state with `npm view @hyperframes/core version dist-tags versions --json` and `npm view @hyperframes/producer version dist-tags versions --json`: `latest` is `0.4.42`, `alpha` is `0.5.0-alpha.14`. - Packed `@hyperframes/core` and `@hyperframes/producer` at both `latest` and `alpha`; all four packed artifacts still contained the bad `Reflect.get(target, prop, receiver)` / `utilsReceiver` wrapper patterns before this fix. - `bun run --cwd packages/core test -- src/compiler/compositionScoping.test.ts` - `bunx oxlint packages/core/src/compiler/compositionScoping.ts packages/core/src/compiler/compositionScoping.test.ts` - `bunx oxfmt --check packages/core/src/compiler/compositionScoping.ts packages/core/src/compiler/compositionScoping.test.ts` - `bun run --cwd packages/core build` - `bun run --cwd packages/core typecheck` - `bun run --cwd packages/producer typecheck` - `bun run --cwd packages/producer build` - `bun test packages/producer/src/services/htmlCompiler.test.ts` - Confirmed the rebuilt core runtime and producer bundles no longer contain the old `Reflect.get(..., receiver)` / `Reflect.set(..., receiver)` scoped-wrapper patterns. - `git diff --check` - Pre-commit also reran lint, format, and typecheck successfully. ### Browser verification Used `agent-browser` against generated local repro pages: - `core latest 0.4.42`: `bodyRead: false`, `titleOpacity: "0"`, `timelineRegistered: false`, `errorCount: 1` - `core alpha 0.5.0-alpha.14`: `bodyRead: false`, `titleOpacity: "0"`, `timelineRegistered: false`, `errorCount: 1` - Patched local wrapper: `bodyRead: true`, `titleOpacity: "1"`, `timelineRegistered: true`, `errorCount: 0` ## Notes - Browser screenshots and the `agent-browser` recordings are local-only under `tmp/issue-606/browser/`, including `issue-606-browser-proof.webm` and `issue-606-after-comment.webm`. - No generated `dist/` artifacts are committed.
