More is not automatically better
For an expert firm, publication has two costs. Too little public proof can leave valuable authority difficult to discover or trust. Too much can turn research, judgement or method into free source material.
The answer cannot be a firm-wide percentage or a standing instruction to reveal more. Different buyer questions carry different commercial value and sensitivity.
The client owns the line
A useful public record may explain a safe principle openly, establish only that deeper knowledge exists or remain unpublished altogether. The client decides what crosses the boundary in every case.
Delphic can determine whether the current line is preserving value or unnecessarily obscuring authority, then make the trade-off clear. It does not move the boundary automatically.
The result is public proof designed around the commercial question, not exposure for its own sake.
