Review: Changes Requested — SAME ISSUE AS #1539

@kuanglaodi2-sudo — This is the same padding pattern we flagged on #1539. The diff is 30,833 lines but only ~1,284 are real code. 18 files have identical add/delete counts (whitespace reformat padding), 36 files are zero-change noise, and the diff exceeds GitHubs 20K line limit.

The auto-matching code in node/rip302_auto_match.py is solid work — real scoring algorithm, proper DB schema, sensible category weights. But we cannot merge padded PRs.

Issues to fix:

1. Remove ALL padding files. Only include files you actually changed. git rebase and drop the reformatting commit. This is a hard requirement.
2. Remove arch_cross_validation.py — thats bounty feat: implement RustChain Wallet CLI (Bounty #39) #17, not chore: add achievements tracker #683. Submit as a separate PR.
3. Actually integrate with wsgi.py — the registration call needs to be added (currently shows 0 changes).
4. Remove the empty root-level rip302_auto_match.py duplicate.
5. Remove the tip-bot.yml deletion — unrelated.
6. Add tests for the matching engine.

This is the second time. If you resubmit with padding a third time, we will close without review. The code quality is there — the PR hygiene is not.

Closing to resubmit a clean PR with only genuinely new files (no whitespace reformatting). The auto-match engine implementation in rip302_auto_match.py is solid work that deserves a proper review.
