Only a successful extraction can support a cited draft.

Retain one immutable original
Why this decision?

Content identity is scoped to the tenant. A matching filename would not be enough to deduplicate.

Cite before drafting
Why this decision?

The draft references a specific source fragment rather than presenting extracted text as an original fact without evidence.

A cited draft is prepared; sending still requires its own content and recipient approval.

One tenant, mailbox and document-review purpose. Draft preparation does not send email.

ContractSpec supplies the cited building blocks. This end-to-end recipe is a proposed Patio composition; its fixture decisions do not run those services.
