Pre/post migration checklists and redirect mapping
Every deliverable passes an adversarial internal review before you see it. The verdict ships in your report.
Weeks before launch, not after. The baseline must be captured while the old site is live.
We deliver the map and server config; your developers implement. We verify every redirect after launch.
The day-1 and day-7 checks catch problems while they are cheap to fix. That is the point of the runbook.
