Safety: Review signals: 1 connection review. 3 static matches retained as context.
Review signals: 1 connection review. 3 static matches retained as context.
Reviewed as expected for a test run: attempted writes that failed, so nothing was written.
Repository processes attempted these non-loopback connections; proxies can hide the final hostname. 9 distinct locations. 17 attributed processes.
2 hardcoded secret matches retained as context; full list in the evidence.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
