Sinking Atlantis – How Breaking up Our Infrastructure Monorepos Saved Us from Pull Request Purgatory

summary
Recursion breaks a single infra monorepo that funnels Terraform changes through Atlantis and an engineering gate into per-team bounded context repos, replacing Atlantis with Spacelift for provisioning and using Argo for app delivery and Terraform for infra. The team faces hundreds of PRs per month that stall releases, so ownership shifts: core infra (networks, org roles, standard stack) stays centralized while teams get projects, namespaces and a repo layout that lets them self-provision. Result is faster autonomous changes, fewer approval bottlenecks and an easier-to-reason codebase — Atlantis effectively sunk.
