🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Enumerates directory contents AND makes external network calls

Automates travel reimbursement by reading email invoices, downloading PDFs, and submitting to an internal FOL system; all network calls are to expected corporate services with no exfiltration pattern.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class D). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.
