Pick the right words for this button

When the options are "OK / Cancel" and nobody is sure what OK does.

Help me label the actions in this dialogue or form.

1. State in one sentence what happens when each action is taken, including anything irreversible.
2. Propose three label options per action.
3. Recommend one, and say why.

Rules I want applied:
- The label names the outcome, not the mechanism. "Delete project" beats "OK".
- A user should be able to read the button alone, with the surrounding text covered, and still predict what it does.
- Never pair a verb with a vague opposite. "Save" against "Cancel" is fine, "Yes" against "No" on a destructive action is not.
- The safe action is the one a distracted person should be able to hit by mistake.

Flag any place where the button wording is fine and the surrounding sentence is the real problem.

Dialogue or form:

Interface copy. Every word inside the product: button labels, error messages, empty states and what things are called.
