[Bug]: Solidity: library calls Lib.f() get no calls edge #5004

Pre-flight checks

• I have checked the Troubleshooting section in the README

What happened?

A Solidity library call Lib.f(...) gets no calls edge, not even when it is made inside the library itself. Base.f() on a contract has the same problem. On OpenZeppelin Contracts v5.4.0 the compiler (solc 0.8.28 AST, referencedDeclaration) resolves 208 library calls inside functions. graphify links 0 of them.

The cause: extract_solidity sends every dotted call to raw_calls with is_member_call: True and no receiver name. The shared cross-file pass in extract.py skips all member calls, and Solidity has no member pass of its own.

Steps to reproduce

Three files in one folder, then graphify update .:

MathLib.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
library MathLib {
    function max(uint256 a, uint256 b) internal pure returns (uint256) { return a > b ? a : b; }
    function clamp(uint256 x, uint256 hi) internal pure returns (uint256) { return MathLib.max(x, hi) == x ? hi : x; }
}

TimeLib.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
library TimeLib { function now48() internal view returns (uint48) { return uint48(block.timestamp); } }

Vault.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
import {MathLib} from "./MathLib.sol";
import "./TimeLib.sol";
contract Vault {
    uint256 public cap; uint48 public updatedAt;
    function setCap(uint256 newCap) external { cap = MathLib.max(newCap, 1); updatedAt = TimeLib.now48(); }
}

Error output or graph output

No calls edge at all. Expected:

setCap() -> max()      (named import)
setCap() -> now48()    (whole-file import)
clamp()  -> max()      (qualified call inside the same library)
