There are some messages that are received from CoreMessage but are not mentioned in ge_prepass.h
When are these messages triggered ? I have searched the whole framework and couldn't find any reference for them.
Thank you for your time.

Those messages could either be private or possibly a plugin, so there may be no way for you to know.

One way to know would be to remove all 'third-part' plugins and see if the messages persist. If they do, then they are almost assuredly private messages.

1018484 internally is MSG_PSLIDER_UPDATE, which is for internal use and is basically sent together with EVMSG_CHANGE (and a few other messages).
1970300003 (0x75706463, 'updc') : BFM_CORE_UPDATECOMMANDS (updates all command buttons), it's being send, when icons need to be updated.
1431323715 (0x55504443, 'UPDC') : internal message BFM_UPDATECONSOLE, and it's send, when the Console dialog needs to be updated.
I don't think, you should (or need to) care about these messages. All of them have pretty specific internal use and are not really meant for public use.

My next question was going to be why are you concerned about these messages. One suspects over-reaching control but I could be mistaken.

Thank you for your replies !
I need to do some calculations when any object of the hierarchy changes.
I will do it in document recalculated event.

What scope of changes? Most existing messages will notify of creation/deletion/transforms/modifications. Even plugin changes should invoke some message from C4D unless implemented poorly (no AddUndo() or something). I would use what is available and worry about outliers if they materialize.
