Every enterprise using AI agents faces the same gap: agents now send emails, issue refunds, and touch production systems, but there's no record of who approved it before it happened. Ceadly adds one line of code, @guard, in front of any consequential agent action. Execution pauses. A named, accountable reviewer decides — Approve, Reject, Modify, or Request More Info. The decision is hashed and timestamped the instant it's made. Not a log. A signature.
