Sorry, may be being slow but if I understand you both right this means:

+ one Irmin log ("repo"?)
+ each component has its own branch within that log

then either

+ within each component branch, there is a linear sequence of messages
at different levels

or

+ within each component branch, there is a hierarchy of subordinate
branches, branching each time a message appears at a lower (finer
grained) debug level

?
