🛡️ Sentinel: Security Audit Complete

[ManupaKDU]

Conducted a thorough security audit of the testping1.py network scanner and the test suite (test_testping1.py). No new critical or high-severity vulnerabilities were found.

The codebase is already highly defensive, featuring robust SSRF filters (including unwrapping IPv4-mapped and tunneling addresses), strict input validation, length bounds checking, type confusion prevention, resource exhaustion limits, timeout configurations, and comprehensive test coverage.

Verified that standard utilities like ping do not require explicit environment clearing (e.g., env={}), as doing so introduces regressions without tangible security benefits.

As per the Sentinel persona constraints and memory instructions, no "security theater" fixes were introduced, and no unimpactful codebase modifications were made. The review is concluded.
