Jun 8, 2015 at 4:17 comment added Mohammad Golshani To prove the forcing is c.c.c, we need our model be somehow $L$-like, for example by looking at section 28 of Jech's set theory book (third millennium), $\Diamond$ is used there. Or in Kanovei paper "A countable definable set of reals containing no definable elements" the use of $L$ (see Lemma 6.4 there), is somehow essential.
Jun 7, 2015 at 6:57 comment added Asaf Karagila Where do Jensen reals (unique solutions to a $\Pi^1_2$ predicate) come into the picture? Is it consistent that they are not minimal, or consistent that they are not c.c.c., or both?
