Prior-valid-state rule

Offline grace requires a previous successful activation or validation. A fresh install, unknown customer, deactivated device, confirmed invalid key, revoked entitlement, refunded access, or expired subscription should not unlock just because the customer is offline.

Grace inputs

Offline grace is a continuity mechanism, not a substitute for ownership.

Prior validation

A recent valid online decision is required before grace can apply.

Grace window

The configured window determines how long continuity can last.

Known-denied state

Confirmed invalid, revoked, refunded, expired, or deactivated states override grace.

Release QA

Test airplane-mode, cache deletion, clock changes, deactivation, refund, and subscription transitions for each product release.
