Description

The required repository-health gate fails because the 452-line English OpenSandbox research archive has no Chinese counterpart. Add the complete Chinese archive covering all numbered sections, API and operation mappings, configuration/errors, historical setup/test design, EPP gaps and recorded 2026-10-13 results.

The original English archive is unchanged. Both the historical Python sketch and Node exec-plugin results remain explicitly distinct from the current in-engine adapter; the new page links the current Chinese mapping. The original disposable local API-key example is replaced with REPLACE_ME to satisfy the repository secret hook, with the substitution explained.

Fixes #39.

Type of Change

• Documentation

Changes

• Add the missing Chinese research page, preserving source provenance and historical boundaries.
• Add the repository-owned proposed process note and independent verification evidence.
• Update the Unreleased changelog.

Testing

• Repository health: 106 PASS, one existing optional release-guide warning, zero FAIL. The translation gap is resolved without changing the checker.
• Hygiene, whitespace, numbered-section/subsection correspondence, fenced-block balance, scoped relative links and unchanged English archive comparison pass.
• Configured-secret comparison and pre-commit secret hook pass; no hook bypass.
• Documentation-only change: no new Docker/cloud execution or product E2E result claimed. Required remote checks are inspected on the latest head before merge.

Checklist / Definition of Done

• Complete Chinese counterpart and current-adapter distinction
• Proposed engineering record and verification evidence
• Changelog, link, health and hygiene checks
• No configured secret values included
• Latest-head required CI/review complete

Independent review

The root reviewer compared all numbered headings and fenced blocks, the opening and closing sections and principal API tables against the English source. Review passed: the 2026-10-13 boundary, current in-engine adapter links and operation semantics are preserved. This review does not replace the latest-head remote CI gates.

Merged after all nine checks succeeded on reviewed head 5af662f. Remote merge confirmed at 2026-10-16T03:59:23Z, merge commit 991c36c. Issue #39 is closed.
