Confirm the package
Start with the product, version, pack name, delivery context and evidence set supplied with the handover.
Verify
Evidence should be checkable after the handover.
Attessia evidence is designed so a buyer can identify the material, compare records, check the stated evidence and retain the result with the delivery file.
Check records
Compare manifests, hashes, filenames and supplied notes against the artifact being reviewed.
Review signatures where supplied
For witness or PQC Core evidence, check the supplied signature records and public verification material.
Keep the evidence trail
Store verification notes, receipts and records alongside the customer handover material for later re-checks.
Verification depth
Each product has a different evidence depth.
Grammar C focuses on structured packaging and consistency checks. PQC Witness adds Attessia-operated witness output. PQC Core lets approved customers operate a post-quantum verification runtime. White-Glove adds post-Core deployment evidence and handover notes.
| Product | What the buyer can check |
|---|---|
| Grammar C Core | Project structure, file-content context, manifests, hashes, notes and rebuildable handover material. |
| PQC Witness Uplift | Attessia witness output, SHA-512 manifest evidence, signature records where included, verification notes and delivery records. |
| PQC Core Self-Install | Customer-operated signature evidence, public verification material, manifests, verifier transcripts and retained evidence records. |
| White-Glove Deployment | Post-Core deployment checks, acceptance notes and operational handover evidence from the agreed support scope. |
Boundary
Verification proves the supplied evidence, not every possible claim.
Verification instructions support package integrity and evidence consistency. They do not replace legal advice, regulated certification, sanctions screening, licence terms or product-specific suitability review.
Package evidence, not secrets
Grammar C and related handover material should exclude credentials, tokens, live production secrets and sensitive signing material before packaging.
