Engineering decision
Use per-PR preview environments to improve review confidence
Preview environments moved review feedback closer to implementation without adding infrastructure cost.
Context
Reviewing changes across multiple products and repositories required faster, more reliable feedback before merge.
Options
- Continue relying primarily on local review and post-merge validation
- Create per-PR preview environments with no added infrastructure cost
Decision
Propose and ship $0-cost per-PR preview environments.
Trade-off
The delivery system needed setup and maintenance, but the review loop became easier to trust.
Outcome
Review confidence improved while infrastructure cost stayed at $0 per PR.
