Common Connection properties

DB and File Connections inherit the common module properties: module name, FID, Folder, revision, active/archive state and notes.

Concern	Contract for every Connection
Environment	Confirm test/production context before save and test. Endpoint labels are not isolation controls.
Identity	Relations use FID, not only module name. Rename does not make an independent copy.
Credentials	Use the type-specific encrypted password control where available; protect configuration/export access and never document plaintext.
Service access	Test under the runtime account, not only the Designer user's identity.
Save/reload	Save persistence is not proof that a running service cache has refreshed. Follow the concrete page's restart/resynchronisation guidance.
Dependencies	Use Check Usage before changing shared paths, credentials, pooling, transactions or endpoint values.
Verification	Test connectivity, then run a controlled Definition/Flow and inspect output plus logs.

DB Connections add engine/authentication/pool/transaction fields. File Connections add paths, masks, names and file-lifecycle fields. Do not apply a setting from one family to the other.
