Summary

Add lifecycle regressions for the raw-byte submission contract adopted in #9593, related to #9551. This is a test-only follow-up; the transport and sorting fixes remain attributed to their upstream authors.

Changes

• Run real generated Python jobs through receipt, approval and execution with UTF-8/CRLF source and a binary payload. Check that the approval retains the received hash and the inbox bytes remain unchanged.
• Exercise newline-only and binary changes before receipt, before approval and after approval, with an execution marker that must remain absent.
• Check API request hashes and raw payloads when a local resolver converts a request into an approved job.
• Exercise filesystem-backed mock Drive transport, including a newline change after the sender declares the hash.

Testing

• Python 3.12.14 on macOS ARM64: the complete syft-job test directory, the existing sync-manager unit tests and the new transport tests pass: 195 passed, including the 13 new cases.
• The same 13 cases on pre-fix: send job files to the DO byte for byte #9593 commit e0915951 produce 5 failures and 8 passes. The current 8a39a62c source passes all 13. No production code is changed.
• All configured hooks on the two new Python files pass with a local Node 22.23.4 runtime. The repository configuration is unchanged. Black, isort, flake8, focused mypy and Bandit checks also pass.
• Dependencies were prepared before evaluation; the generated Python workers ran with uv offline. Drive is mocked. Native Windows, real OAuth/Drive, enclave execution and model evaluation are outside this test run.
