Summary

reuse the already authenticated Machine while deserializing a recovered Submission
avoid creating a second SSHContext for one-time authentication methods such as TOTP
add a regression test proving recovery does not call Machine.deserialize

Closes #631

Summary by CodeRabbit

Bug Fixes
- Improved submission recovery from saved data by preserving the existing authenticated machine context.
- Prevented unnecessary machine reconstruction during recovery, helping maintain consistent connection state.
Tests
- Added coverage verifying that recovery reuses the current machine context and avoids creating a replacement.

Reuse the already authenticated machine while deserializing a recovered submission so one-time authentication methods do not create a second connection. Add a regression test that rejects machine reconstruction during recovery.\n\nCloses deepmodeling#631\n\nCoding-Agent: Codex\nCodex-Version: codex-cli 0.149.0\nModel: gpt-5.6-sol\nReasoning-Effort: xhigh

📝 Walkthrough

Walkthrough

Submission recovery now passes the existing authenticated machine to Submission.deserialize. The recovery test verifies that Machine.deserialize is not called and that the current machine remains in use.

Changes

Submission recovery

Layer / File(s)	Summary
Reuse authenticated machine during recovery `dpdispatcher/submission.py`, `tests/test_class_submission.py`	`try_recover_from_json` passes `self.machine` to `Submission.deserialize` and removes the separate machine rebinding flow. The test mocks remote file access and verifies that machine deserialization is skipped and the existing machine remains unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5097a

When recovered submission data does not match, the shared machine context can remain attached to the discarded recovery object, causing a retry to operate on the wrong submission. This bounded recovery-path correctness issue should be fixed before merging.

Title check	✅ Passed	The title clearly and concisely describes the main change: reusing the existing machine during submission recovery.
Linked Issues check	✅ Passed	The implementation passes the existing machine to Submission.deserialize and removes redundant machine reconstruction, satisfying issue `#631`.
Out of Scope Changes check	✅ Passed	The code and regression test directly support machine reuse during submission recovery and contain no unrelated changes.

the shared context remains bound to self when recovered data fails the self ==
submission validation; avoid passing the shared machine during deserialization
until validation completes, or explicitly rebind machine.context.submission to
self before raising. Add a regression test covering the mismatch path and
confirming subsequent retries use the original submission.
