Description

One Line Summary

Construct encoded objects with own data properties so an input proto key is not silently lost or treated as a prototype setter.

Compatibility and observable changes

No sentinel, native protocol, or public API changes. An own proto key now survives the encoding round trip; ordinary null/scalar/array behavior is preserved.

Details

Motivation

The source audit reproduced the failure paths described below. This PR contains only the associated fix; unrelated audit changes are in separate PRs.

Scope

  • src/helpers.ts

Testing

Actual-source JS reproduction fails before this change and passes after it; existing helper and full SDK tests pass. Complements the null-preservation work merged in #1946.

Each code/tooling fix was also applied independently to upstream commit a70312207cf094ac361eaa9196c317acb175c2cd and passed its targeted external actual-source diagnostics. Documentation snippets were checked separately. Native diagnostic harnesses use bridge/SDK doubles and are not an end-to-end push test.

On the combined audit branch:

  • Existing SDK suite: 5 files, 262 tests pass; unchanged 95% coverage thresholds pass.
  • vp check: formatting, lint and type checks pass; native Spotless check passes.
  • Both example apps: Android Debug and unsigned iOS Simulator builds pass.
  • Both example apps: iOS and Android production Metro bundles pass.

No checked-in test files were added or modified; regression evidence comes from external diagnostic harnesses and the existing suite. No physical-device, live notification delivery, Appium/BrowserStack, or release-workflow execution is claimed. The no-location example's stale native lock was updated locally to resolve the current SDK for verification; generated locks are not part of this PR.

Checklist

  • Required description sections completed.
  • Scope and observable/API behavior explained.
  • Diff reviewed and targeted regression checks run.
  • Automated checks and device-testing limitations documented.
