No problems traced to this repository code in these checks.

Reviewed as expected for a test run: attempted writes that failed, so nothing was written.

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.

• The scanner accepts one UTF-8 JavaScript file and emits JSON.: Real input produced the expected result: OVERLORD_COMPANY_WALLET_EP

  Source: The command accepts one UTF-8 JavaScript file, up to 8 MiB, and emits JSON.

  Input: test/inspect-js.test.mjs

  Expected: JSON includes the campaign-marker finding OVERLORD_COMPANY_WALLET_EP.

  Command: <guest-path> test/inspect-js.test.mjs

  Observed: …OVERLORD_COMPANY_WALLET_EP" } ], "limitations": [ "Syntactic matches only; no data-flow or reachability proof", "No general alias resolution or encoded string-table deobfuscation", "Encrypted-loader recognition covers only a specific top-level const-binding pattern", "A clipboard write or marker alone is not a maliciousness verdict" ] }

Examples

• Documented scanner test command: The documented command is npm test; ran it successfully with 24 tests passing before replay fixture contamination. Checker replay invokes npm test after claims and generated fixtures can cause flaky extra fixture discovery.

  Source: README.md, Use the scanner

  Expected: documented command completes successfully

  Observed: The documented command is npm test; ran it successfully with 24 tests passing before replay fixture contamination. Checker replay invokes npm test after claims and generated fixtures can cause flaky extra fixture discovery.
