strange behavior under 3.6.1 multisite

I must be missing something, perhaps it is late-night tired eyes.

Working 1.3.2 supercache install under wp 3.6.1 multisite, cached files created and served just fine for logged out users.

Except I noticed that the post transition status functionality has not been working – an individual post on its own page will update, but not the front page index for example.

So I tried to turn on debug. No debug output, not to error log, not if it I give it an error log file, nothing.

So just for the heck of it, I tried making sure the wpsc_post_transition hook was added at init, exactly like how supercache does it, just doubled it at init action.

Remember, at init, all plugins should be loaded.

Except the result is php isn’t aware of wpsc_post_transition when I try to call it at init. It is NOT loaded.

And yet supercache works.

So it is running for logged out users to create cached pages, and I can see the control panel just fine and it is network activated for all users.

But no debug, no transition status functionality.

What am I missing?

I guess this is a critical question: when a user is logged in, does advanced-cache – > phase1 -> phase2 load? Or is that skipped? If it is skipped for logged in, it would explain why wpsc_post_transition is not found.
