What does HRESULT 0x80280047 (TPM_E_CONTEXT_GAP) mean?

TPM_E_CONTEXT_GAP

The saved context fell outside the accepted context-counter window

TPM_E_CONTEXT_GAP (0x80280047) means TPM context sequencing has advanced far enough that the saved context blob can no longer be restored safely. The blob need not be corrupt; its age/order is the problem.

Evidence to capture

Capture context blob identity, saved context counter/sequence, intervening context save/load activity, TPM reset/lifecycle events, and the resource that the application expects to restore.

Focused correction

Recreate or reload the resource and obtain a fresh context under the current TPM state. Avoid long-lived caching patterns that allow too many intervening context operations before restore.
