+Status:

+
+Context:
+Quotation revision was introduced in Task E, but the rules before approval workflow were still ambiguous.
+Task E.1 needs a stable rule so Task F can build approval on top without changing quotation lineage again.
+
+Decision:
+- Revision is allowed only when the current quotation status is `approved`, `sent`, `accepted`, or `rejected`.
+- Revision is not allowed for `draft` or `cancelled`.
+- A new revision keeps the same quotation family using `parentQuotationId`.
+- A new revision copies header, items, customers, and topics only.
+- A new revision is created with the `revised` status when that master option exists.
+
+Consequences:
+- Sales can revise commercially meaningful documents without reopening early drafts.
+- Approval work can later key off a stable quotation family and revision chain.
+- Follow-ups and attachments are still out of the revision snapshot and remain technical debt until explicitly designed.
