Finished, but currently not rideable as just as I was thinking how great tubeless was on the way home, the back tyre started to deflate pretty quickly. It holds air but is bubbling at the rim in multiple places. Gonna get some more sealant next week.
Only thing else left to do is internally routing the front hose, which is a PITA since I'll need to cut it and rebleed; and find some bottle mount bolts.
Very happy with it generally, even though it's half a kg more than I thought it'd be. Not that that really matters for a commuter bike.
