Summary boundary: A copy transfers data across a boundary whose destination constraints must be checked by the caller.
The pack does not provide a callable signature for this record; the watched access path is shown directly.

No CWE mapping in this fact
The model classifies the behavior as copy; no CWE relationship is attached to this record.
Attacker's-eye view · copy
A crafted value exceeds the destination's capacity or crosses an unintended ownership boundary.
// modeled boundary: Argument[0] -> ReturnValue
strdup(attacker_influenced_value);
1Confirm destination capacity.
2Check length and encoding assumptions.
3Review ownership and lifetime rules.
These checks require the surrounding codebase. The model names the boundary; it does not decide reachability or prove that a guard dominates every path.
Is this a bug in your code?Atropos stops here — by design
Atropos identifies Argument[0] -> ReturnValue as a copy summary. It cannot see whether untrusted data reaches this call in your repository.
Lachesis is the codebase-level step: it traces reachability and guards for this symbol.
