What does HRESULT 0x80280051 (TPM_E_DAA_INPUT_DATA0) mean?

TPM_E_DAA_INPUT_DATA0

TPM_E_DAA_INPUT_DATA0: diagnose the owning boundary

TPM_E_DAA_INPUT_DATA0 (0x80280051) is documented as The consistency check on DAA parameter inputData0 has failed. Treat that wording as the specific TPM 1.2 DAA inputData0 validation boundary; it is more useful than a generic “component failed” label.

Evidence that matters

Preserve the exact inputData0 bytes/length, DAA stage and issuer/TPM transcript identity. Regenerate the input from the same protocol attempt and compare encoding byte-for-byte.

Interpretation and verification

Keep the affected object and caller identity stable while changing only the rejected prerequisite. The correction is proven when the original operation crosses this boundary with the intended state or output. If a different HRESULT appears afterward, preserve it as a separate later-stage result rather than folding it back into TPM_E_DAA_INPUT_DATA0.
