Definition
A separate authorization decision taken when an existing delegation is widened in scope, population, autonomy, or consequence. It carries its own evidence, its own correction capacity check, and its own dependence review, and it is recorded as a transition on the grant.
It matters because expansion is normally treated as the reward for success rather than as a new delegation. Requiring the decision is the direct block on the automation ratchet, and it keeps an authority grant readable against what the system now does.

Tests that show it is in place
- Widening a delegation cannot be shipped without an expansion record naming its evidence.
- The record includes a correction capacity check and a dependence review, not only a risk note.
- Expansion transitions are visible in the grant's state history.
Evidence to keep
- Artifact: An expansion record with evidence, correction capacity check, and dependence review.
- Behavior: An expansion deferred because correction capacity had not grown with the proposed scope.
- Metric: Share of scope increases accompanied by an expansion record.
- Threshold: Target 100%; gaps are reconciled as authority drift.
