✅ Final review complete — no blockers (commit e4c31ad)

[thepastaclaw]

Final validation — Codex + Sonnet

The PR is an exact file-for-file revert of #4277 and consistently removes the encrypted txMetadata implementation across Rust, FFI/JNI, Kotlin APIs, dependencies, exports, and tests. No functional or blocking issue remains, but the revert reintroduces two unused Kotlin imports that should be removed as a small cleanup.

💬 Nitpick: Unused coroutine imports reintroduced by the revert

This revert re-adds Dispatchers and withContext, but neither symbol is referenced anywhere in the file. They were also unused before #4277—the removed encrypted-document methods did not reference them—so restoring them only creates dead-import IDE and linter noise. Delete both imports.
