## Delivery ownership — finding to fix

Version-controlled definition surfaces are delivered by draft pull request and owned through exact-head review and merge.

Runtime-local definition surfaces are delivered in place: back up the current state, apply the change, validate it, and record the reversible before/after evidence.
