I think its a best-judgment kind of thing. If I didn't have any deburring stuff, just use a pocket knife VERY lightly around the edge

Probably stating the obvious, but don't want to chamfer the edges too much or you end up with bell-bottom bullets!
You fixed it but being a GC mould, I wouldn't worry. You're going to 'replace' the base with a GC anyway. Worst you could get is some flash on the shank.
Just use a small section of abrasive paper to soften the edge / remove any burrs ... a flat base , sharp edge is preferred . The gas check will go over the base .
I wouldn't use a chamfering tool or even a pocket knife .
Run a cotten Q-Tip around the edge ...it will snag any tiny burr's .
If the Q-Tip doesn't show any burrs ... leave it alone or very lightly smoot the edge with wet-r-dry abrasive paper .

What does the bottom of the sprue plate look like? It could probably use a bit of attention too.
On my RCBS molds, if the bottom of the sprue plate's worn I'd lap it flat again. But on a Lyman the "mold repair kit" is so inexpensive that I just replace the plate. The repair kit is available from many sources. Here's just one of many examples: https://www.midwayusa.com/product/1010248998
