It means she did something that is respectful of your wishes or otherwise wouldn't disrespect you.

The phrase “She did right by you” means: She treated you fairly, kindly, or honorably. She acted in your best interest or did something good for you. Examples: "Even though she had to leave, she did right by you in the end." She made a good or respectful decision regarding you. "He always tries to do right by his friends." He treats his friends well and fairly. It's a common expression in conversational English, often meaning someone fulfilled their moral or emotional responsibility toward someone else.

Whatever she did, she honoured you plenty. She didn't disrespect or mistreat you. This has a very broad meaning. She could be your wife, looking after you well, and staying loyal. She could be a custodian of your legacy, preserving your work authentically and giving credit where it's due.
