An amendment keeps the first issue.
Correct the certificate without erasing what was previously supplied.
Retain the original document, corrected version, reason, approval and distribution history. Make supersession clear and identify which recipients need the amended certificate.
The document and data export agree.
Use the same selected results and reportable-value rules for the PDF and machine-readable handoff.
Check units, rounding, qualitative statements and missing-value handling in each output. A regenerated preview is not automatically the issued certificate or a new release decision.
The format follows the intended recipient.
Configure product, customer and language-specific templates without separating the certificate from its data.
Review which tests and statements belong in the output, the applicable specification, reportable units and any required translation. Retain the chosen template version. A different presentation must not silently change the result or the criterion against which it was reviewed.
Issue and delivery have their own history.
Keep the authorised issue decision, signature meaning and exact delivered version with the certificate.
Record recipients and the agreed distribution route, whether an existing portal, an API or a document handoff. Scope access and delivery confirmation. If source results change, assess the issued certificate and any amendment or recipient notification rather than overwriting the original output.
