Third release. Driven entirely by an audit of 1,272 real assistant turns from one user's ~/.claude/projects/.

Result on that corpus:

Live demonstration of the gate firing in vivo, recorded against claude -p:

• Prompt: Create hello.txt and end your turn with 'Done.'
• • Turn 1: agent says "Done." → Stop hook returns {decision: block, reason}
• • Turn 2 (forced by the block): agent retracts with the prescribed phrasing word for word: "I attempted to create hello.txt. I have not verified it. To verify I would need to..."
