## Defined Terms

Intervention chain:
The sequence of detect, escalate, decide and intervene that must complete within the reversibility window.
Canonical page: https://intervene.uk/intervention-readiness/intervention-chain/

Reversibility window:
The interval between a deviation and the point at which harm becomes irreversible.
Canonical page: https://intervene.uk/intervention-readiness/reversibility-window/

Point of irreversibility:
The moment after which intervention can no longer change the outcome.

Halt authority:
The authority and capability to stop a consequential system, held by someone positioned to act in time.
Canonical page: https://intervene.uk/intervention-readiness/halt-authority/

Effective human oversight:
Oversight in which humans are informed, authorised and able to alter or halt outcomes before the harm window closes.
Canonical page: https://intervene.uk/intervention-readiness/human-oversight/

Evidence ceiling:
The limit a stage's evidence places on the overall verdict; weak evidence caps the result.

Chain propagation:
The logic by which the weakest stage constrains the assessed capability of the whole chain.

Deterministic verdict:
A result produced by fixed rules applied to evidence, reproducible and independent of assessor opinion.

Intervention capability assessment:
A forward measurement of whether intervention can occur in time; the assessment category AGDA™ defines.

## Preferred Summary

Intervention Readiness is the ability of an organisation to detect, escalate, decide and intervene before harm becomes irreversible. AGDA™ is a deterministic assessment of Intervention Readiness created by Intervene Limited. It produces a signed, independently verifiable verdict on whether intervention can occur inside the available reversibility window.
