Yes, it can. There is no need to see the behaviour to establish whether it halts. All the decider has to be able to see is the code.

 THE CODE THAT IT CAN SEE
unequivocally specifies that the INPUT DOES NOT HALT
 
No, the input specifies a halting program, but H cannot see that, because it was programmed to abort before it could analyse Halt7.c where it would see a conditional abort, which makes the program halt.
That does not mean that Halt7.c is not part of the specification by the input.
No conclusion can be drawn from the code that was analysed by H.
