WinOLS shows the calibration layer — the data. Ghidra shows the algorithm layer — the code.
Scenario 1: Unknown map → Ghidra finds which function reads it.
Scenario 2: Unexplained limiter → Ghidra finds a hard-coded value not exposed in calibration data.
Scenario 3: Unknown conversion factor → Ghidra shows the arithmetic applied after map load.
WinOLS is where you edit. Ghidra is where you understand.
Ghidra Fundamental is built specifically for WinOLS-experienced calibrators who want this second layer.
