A Pascal/Delphi procedure or function defined ONLY in the implementation section (no interface declaration, not a class method) had no node of its own, so extractPascalDefProc's caller lookup fell through to the nodeStack top — the file node. Every call in such a routine's body was lumped under the unit: callers returned the file, and impact couldn't attribute the call to the routine. (Methods were fine — they get a node from their class declaration.) Fix: when extractPascalDefProc finds no existing node for a FREE routine (a name with no `.`), create a function node for it and attribute the body's calls to it. Interface-declared free routines already have a node (found via the methodIndex), so there's no duplicate; methods keep their existing class-declaration node. PascalCoin A/B: +511 / -145 — the +511 are calls now correctly attributed to their actual routine (`allocate_new_datablock -> TDisposables::GetMem`), replacing -145 file-level aggregates; +248 new function nodes for the implementation-only routines. New synthetic test asserts a free routine's call attributes to it alongside a method caller. EXTRACTION_VERSION 17->18. Full suite green.
