When the Deploy Was Green but Users Still Saw the Old Build: Field Notes on a Gate That Verifies Your Shipped Commit Reached the Edge
When a deploy reports success but production keeps serving the old build, a post-deploy gate that verifies your shipped commit actually reached the edge via a build stamp closes the gap. Field notes with real operational numbers.
When CI Passes but App Review Rejects Your Screenshots — Field Notes on Measuring the Freshness of Your Validation Rules
Store asset validation can pass in CI and still get rejected in review, because the rules themselves go stale. Move store specs into a freshness-dated contract file, then add locale overflow checks and perceptual diffs.
When a Local iOS Build Passes but CI's TestFlight Upload Rejects the Signature — Field Notes on match Code-Signing Drift
Running fastlane match on CI can produce builds that succeed while only the TestFlight upload fails on signing. These field notes show how to diagnose the certificate/profile drift reproducibly, lock CI to readonly, and add a pre-upload gate that stops bad signatures before they reach Apple.
