Explain the concept and rules of advocacy as the honest art of persuasion.

The concept: advocacy as the persuasion craft — the cause advanced by argument (the lawyer's public voice: the courtroom, the tribunal, the negotiation table). The art's principles (the masters' canon): persuasion honest (credibility the capital — once caught, never trusted; candour as strategy, ethics as the art's core); the story told (the narrative's power — facts arranged around a theme, the one-line theory); simplicity (the complex made clear — brilliance is clarity, not confusion); preparation total (the "ninety per cent preparation" lore — inspiration as perspiration's product; the overreach avoided). The rules' summary: know the case, know the court, know the self — the three knowledges; the rules of advocacy are the rules of Unit 1's ethics applied to performance (the zealous advocate within the law's bounds).
