Approval | Agent Revision Markup

An approval is not a checkbox. It is a signed object bound to one specific change in one specific session - it cannot be replayed onto anything else.

Field	Type	What it is
`schemaVersion`	integer	Wire schema version.
`sessionId`	string	The session this approval belongs to.
`manifestHash`	string	The manifest context it was given under.
`approvalId`	string	Unique id for this approval.
`mandateId`	string	The mandate the agent was acting under.
`approved`	boolean	The decision.
`approvedBy`	string	Who approved, as stated in the manifest.
`approvedAt`	string	When.
`approvalSubjectHash`	string	Hash of what was being approved.
`approvedDraftHash`	string	Hash of the exact draft bytes the human saw.
`approvalSignature`	object	Signed by an approver key listed in the manifest.

The two hashes are the point: change one byte of the draft after approval, and the binding breaks. A runtime must verify the approval before signing the turn that carries it.
