Carry a reviewed handoff into a new native session, or return the current worked session to its original harness under a new identity. CLI and TUI let users select event ranges, edit the complete handoff, inspect destination metadata and explicitly confirm publication. Return-new binds the selected completed parent and rechecks the current source rather than copying its previous import.

The handoff is recorded as derived user-provided context, with provenance and durable recovery evidence. It does not claim full-history continuity or enable in-place updates. Full return is verified for the pinned Claude/Codex schemas. OpenCode 2.0.22/2.0.23 accepts the user handoff with PARTIAL target coverage because its importer adds a model variant; full return to OpenCode fails before a new READY record.

Validation:

• Current integrated suite: 3,497 passed, 82 external-client prerequisites skipped; separate native gates cover the specified clients.
• Isolated actual Claude 2.1.209 / Codex 0.144.4: eight full/summary and worked-source resume cases passed.
• Isolated OpenCode 2.0.22/2.0.23: eleven scoped handoff/return, rejection and cold-resume cases passed.
• Independent reviews cover core, emitters, CLI/TUI, the OpenCode scoped proof and the final integrated diff.
• Installed-wheel gates: 93 passed with no skips (CLI, handoff/return runtime and headless TUI).
• Wheel/sdist built; all 69 packaged Python/TCSS files match the reviewed source. No core runtime dependency added; optional TUI remains Textual 8.2.8.

In-place update remains unavailable pending native concurrency and recovery proofs. The optional web dashboard is a separate change.
