SDIAG_E_NOVERIFIER
SDIAG_E_NOVERIFIER identifies this condition: a troubleshooting pack declares a root cause/resolution flow that requires verification but provides no usable verifier.
Meaning in the subsystem
A troubleshooting pack has distinct initialization, detection, resolution, and verification phases. Keep the ordinary result report together with the debug report, and identify whether the pack script, PowerShell host, managed host, resource loader, trust check, or verifier produced the first failure.
A resolver reporting success is not equivalent to an independent verifier confirming the state change.
Minimum useful evidence
- Manifest root-cause and resolution definitions
- Verifier script/resource identifiers and files included in the signed pack
- Pack build output, catalog contents, and post-build modifications
- Which resolution path attempts verification
Isolate the responsible condition
- Inspect the packaged manifest and catalog rather than source directories.
- Add a minimal verifier that observes the corrected state without reapplying it.
- Run detect/resolve/verify on both present and absent root-cause cases.
Regression proof
The corrective action should be narrow: Include and sign the required verifier, reference it correctly in the manifest, and keep verification read-only where possible.
Close the incident only when the verifier distinguishes fixed, not fixed, and not found outcomes and survives pack extraction/deployment.
