A unit holds credentials for its members, by tool and setting - needed once,
not once per agent, and other units never get them.
- UnitConfig.credentials, protected by ConfigSecrets like every secret.
- OrgChart.ToolSettingsFor: an agent's own settings, completed by the nearest
unit up that holds the value; own non-empty values win; no tool is granted.
Used for runs, tool jobs and preflight probes.
- OrgAdministration.SetUnitCredential, PUT /organisation/units/{id}/credentials;
the view lists held settings, never values.
- Templates never carry unit credentials; they are named instead.
