**Security note**: this issue is public. If any flagged finding is a real, exploitable vulnerability, please redirect to your `SECURITY.md` policy or open a [private security advisory](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability) instead. We're happy to close this and re-submit privately.

Megaproject â high spam risk
Could not determine 'encode/starlette' star count (GitHub API rate-limited or unreachable). When in doubt about repo size, prefer opening a focused PR or a discussion rather than an issue.
Already filed
27/84 findings (32%) on this scan are already flagged as test-file, won't-fix, or suppressed. The scan is too noisy to file as a single issue. Curate down to specific actionable findings, or address the FP source first.
