iOS Subscriptions are Hard

" summary

Explains why StoreKit, receipt files, and servers make subscriptions messy and gives a practical rollout: start with on-device validation only for prototypes, move to server-side validation that persists raw receipts and unrolled transactions, refresh receipts roughly daily to keep active-subscriber counts accurate (scales past ~100k receipts), and add a signing server to support subscription offers; calls out missing price data in receipts and that App Store server notifications do not reliably signal renewals.
