I like to call a tank cycled when these two conditions are met: a full water change wont undo or reset things, and #2 system is able to keep initial bioloading alive. an uncycled reef cannot keep things alive.
you're cycled but only as mature as that rock has been underwater, and if its not liferock (painted dry rock needs a couple weeks to activate) you might have been cycled a hundred years ago, thats considered rather mature active substrate. you arent mid-cycle, you're done cycle but awaiting maturity: lots of fanworms, pods, sponges, things that add to surface area over time
nothing you added did your cycle; your coralline live rock showed up cycled and didnt undo.
