Subscription access should follow verified entitlement state rather than the success animation shown after a purchase. Purchases can be pending, refunded, renewed or restored on another device. A reliable product separates store transaction evidence, account ownership and the application capability unlocked by that evidence.
The contract to define first
Verify transactions through the supported store mechanisms and maintain a server-side entitlement projection where the architecture requires it. Reconcile notifications and restores instead of assuming events arrive once and in order. A customer-support override should be explicit, time-bound and auditable; it must not overwrite the transaction history used for later reconciliation.
A worked scenario
A synthetic user purchases on one device and signs in on another. The second device should resolve the account’s verified access without requiring a second purchase. If the store later reports a refund, the product should follow its documented entitlement and communication policy.
An implementation and review sequence
- Define entitlement states and their authoritative evidence
- Separate store identity from application account linking
- Reconcile purchase restore refund and notification paths
Failure cases worth testing
| Condition or input | Expected behavior |
|---|---|
| A store notification is duplicated | Access is not granted twice or extended incorrectly |
| Purchase is pending | The UI does not claim confirmed access |
| User restores on another device | The correct account receives verified entitlement |

Tradeoffs and limits
A single boolean premium flag is convenient but loses the state needed to explain pending purchases and recovery. A small explicit state model is easier to support as the product grows.
Use the result to make a decision
The practical output is straightforward: separate store transaction status from app access and support actions. Keep the assumptions with the artifact so a product owner, implementer or prospective partner can review the same decision. A useful handoff states the supported scope, the evidence collected and the remaining dependency instead of treating a successful demonstration as proof of every operating condition.

What should determine subscription access?
Subscription access should follow verified entitlement state rather than the success animation shown after a purchase. A single boolean premium flag is convenient but loses the state needed to explain pending purchases and recovery.
Which failure cases should be included in the review?
Include these explicit cases: A store notification is duplicated: access is not granted twice or extended incorrectly; Purchase is pending: the UI does not claim confirmed access; User restores on another device: the correct account receives verified entitlement.
