Yes , we are secretive ... Learn to deal with it ... Research more about how Pakistani defense procurements/projects are done/revealed ! For starters , try Norinco A-100 which was purchased years before but revealed only after Azm-Nau III exercise ... The same is true for Babur , Ra'ad , H-4 and Nasr which were completed in total radio silence ...
There are pics of JFT carrying SD - 10 ... Now you can make a thousand excuses to remain in denial mode that it was just a dummy , the missile never got inducted , the test was unsuccessful
...
What is so shameful about an aircraft firing a missile ?
A couple of other missiles are validated and integrated on the JFT but do you really think they would show a video everytime just to please/convince you ?
Chose what you want to believe , it will not change the reality on ground ...
