Hey Abiola — thanks for putting this together. A few things need attention before this can be merged:

1. CI Lint is failing

The Lint check failed in 10 seconds, which means there are obvious lint/format errors. Please run ruff check and ruff format locally and fix all issues before pushing again.

2. PR description is missing

This PR touches 17 files with +399 / -212 lines of changes across the firewall control plane, policy engine, Circle client, and more — but there's no description explaining:

• What was changed and why
• How to test it
• What problem this solves

Please add a proper PR description so reviewers can understand the scope and intent.

3. Title typo

"update firewalle control plane" → should be "firewall" (extra 'e').

4. Explain the changes

From what I can see, the key files modified are:

• policy.py (+96/-79) — policy engine changes
• circle_client.py (+92/-58) — Circle integration updates
• client.py (+61/-13) — client interface changes
• routes.py (+32/-16) — API route updates
• onboarding.py (+23/-14) — onboarding flow changes
• models.py (+19/-0) — new model additions

Please document what each major change does so we can review effectively.
