Consent Backpropagation
Consent is not a checkbox.
Consent is how systems learn from the people they affect.
A consent breach is not only a moral event. It is an update signal.
Consent backpropagation traces a breach backward through the dependency chain until it reaches a node with both care and update-authority.
If the signal terminates in the affected party, the system is extracting the cost of its own correction.
If no upstream node can receive and act on the signal, the actor or structure is incompatible with the protocol — not as moral evil, but because it cannot participate in cooperative intelligence without corrupting the feedback field.
Not morality: compatibility
The system does not need to declare that someone is evil.
It can declare that a node is not currently compatible with this protocol.
In moral systems, the question is often: who is good, who is bad, who is blameworthy?
In this system, the question is more precise:
Can this node receive breach-signal, metabolize it, and alter future behavior?
If yes, compatibility can continue.
If no, containment, repair, or exclusion becomes rational — not as punishment, but as substrate protection.
Care is technical
Care does not mean sentimentality. It means update-readiness.
A node cares if it can receive the signal without punishing it, preserve it without distorting it, trace relevant dependencies, identify breached scope, alter future behavior, repair downstream damage, change incentives, constrain incompatible actors, improve context gathering, and prevent recurrence.
Care is the capacity to treat another’s consent-signal as system-relevant information.
Authority matters
Someone may care but lack authority.
Someone may have authority but refuse care.
Someone may be a witness but not an updater.
A system becomes non-coercive only when care and update-power can meet somewhere.
The operational test
Does this system have somewhere for consent-signal to go?
Does that somewhere have the power to change anything?
If the answer is no, the breached person is being made to carry the system’s learning cost.
Compatibility criterion
A compatible participant is not someone who never breaches consent.
A compatible participant is someone whose behavior remains updateable by consent feedback.
Humans will miss context. Institutions will make mistakes. AI systems will misread. Ambiguity will happen.
The question is not perfection.
The question is whether breach-signal can propagate.
The shortest version
Morality says care should happen.
Consent backpropagation shows where care must route for learning to occur.
