Review signals: 1 connection review, 1 encoded blob, 1 known vulnerability. 1 static matches retained as context.

Reviewed as expected for a test run: attempted writes that failed, so nothing was written; package managers (cargo) downloaded dependencies over HTTPS; package managers (rustup-init) downloaded dependencies over HTTPS; resolver address lookups that send no data; wrote only to its own open file handles.

Repository processes attempted these non-loopback connections; proxies can hide the final hostname. 8 distinct locations. 2 attributed processes.

Source contains encoded blob; review its purpose. src/mandacaru/integrals/libmandacaru_integrals.dylib

OSV reports a known vulnerability in this dependency version. paste

1 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.

• Molecular DFT calculation returns an energy and convergence result: Real input produced the expected result: "converged": true

  Source: result.optimal_energy

  Input: H2 geometry; method=dft; xc=pbe; grid_spacing=.35

  Expected: converged true and energy -26.494814943554836 eV

  Command: <guest-path> /tmp/molecule.json --xc pbe --grid-spacing 0.35 --threads 2

  Observed: …"converged": true, "method": "dft" }

Examples

• README molecular DFT calculation prints an energy and forces: command completed successfully

  Source: README.md#Install-and-run

  Input: H2 geometry; method=dft; xc=pbe; grid_spacing=.35

  Expected: converged true

  Command: <guest-path> /tmp/molecule.json --xc pbe --grid-spacing 0.35 --threads 2

  Observed: { "energy_ev": -26.494814943554836, "converged": true, "method": "dft" }
