MacOS – Failed startup after 10.10. upgrade

After upgrading to 10.10.4 from 10.10.2, my Macbook Pro (late 2013) boots up to a blank screen with the mouse cursor displayed briefly every 10 seconds. Booting to safe mode and resetting the SMC or PRAM have not worked.

Booting into recovery mode and examining /var/log/system.log, sandbox permissions appear to prevent several services from starting, including sandboxd itself.

There's a longer log here.
