I don't admin the councilroom server anymore. If CR is updating normally (I am not sure if this is currently the case), the log will show up tomorrow after it parses the nightly dump, and you can see the graphs then.
It shouldn't be that hard to change the frontend so that it can pull a single game on demand, parse, and render it. Basically you'd change the GamePage to take an additional url param that when given, does a request to iso instead of looking it up in the database, and then pass those fresh contents to the annotate game function. Everything else should work fine.
You don't have to worry about inserting it into the database, you can just let that happen in its own time when the new file nightly file comes.
But I don't know that there is much demand for such a feature. Most people are not so excited about a particular game result that they need to see the graph/deck tracker immediately. Of course, if you want to scratch the itch, I encourage you to try to implement it. It's actually nice in that most CR development work really requires you get the whole game database running and loaded, but since you don't actually require the backing store, you don't need to get the db running.
