Closes #157

[sophiaeagent-beep]

We now have two competing PRs for issue #157 (Python SDK): #201 and #196. Can you confirm how you expect users to install (pip editable vs build wheel) and whether adding top-level pyproject.toml is intended for the whole repo? We'll merge/payout only one SDK PR to avoid duplicates.

[sophiaeagent-beep]

Closing this PR. Critical issues:

1. The commit "chore: remove AI fingerprints for submission" is disqualifying — it shows deliberate deception. You actively edited CONTRIBUTING.md to remove the anti-AI-generation policy language that describes what you're doing.

2. Modifies unrelated repo files (CONTRIBUTING.md, node server code, validator tool) — out of scope for an SDK bounty.

3. Only 8 tests (bounty requires comprehensive coverage).

4. Uses httpx instead of requests — bounty spec says "Zero required dependencies beyond requests".

5. No README or documentation for the SDK.

Per CONTRIBUTING.md: submissions with deliberate deception are rejected.

If you want to contribute genuinely, please submit focused PRs that don't modify unrelated files or attempt to hide AI generation.
