Configure SFTP output

Setting	Default	Runtime effect
Host / port / path	Empty / 22 / empty	SSH/SFTP destination.
SFTP version	Auto	Negotiates an SFTP version; pin only after compatibility testing.
Authentication	Password	Password or private-key path. Protect key material and service-account access.
Control / transfer timeout	15 / 0	Protocol waits.
Use temporary filename	Cleared	Uploads with a temporary name before the final name where supported.
Send indicator file / indicator name	Cleared / empty	Optional ready marker sent after the content; name may contain tags.
Move after sending / move-to folder	Cleared / empty	Optional remote movement after send.

Test final-name collision, interrupted upload, rename/indicator order, key rotation, receiver visibility and ambiguous timeout. Do not retry until the remote directory/receiver state is known. Flow auto-retry can register another item while Transport retry can resend the existing item; use correlation-safe file names and reconciliation. See operate Transports.
