Status:
accepted

Context:
Task E introduced quotation attachments as metadata only.
Task E.1 confirms that approval should not start on top of an unstable file-storage design.

Decision:
- Keep quotation attachments metadata-only for now.
- Store file identity, original name, path, type, size, uploader, and timestamps in CRM tables.
- Do not build upload transport, storage provider logic, signed download URLs, or binary retention policy in Task E or E.1.

Consequences:
- Task F can reference attachment metadata without being blocked by storage implementation details.
- A later storage task must define provider abstraction, permission checks, retention rules, and migration strategy for existing metadata rows.
