Unpacked comprehension
Many of the initial cases were actually triggering shortcomings in Ostrich' handling of regexes. Notably, support for capture groups and non-greedy matching are missing or incomplete. I manually rewrote some of those regexes, which is straightforward when we only care about Boolean yes/no matching. The transformation probably should be done in Ostrich itself, but isn't yet there. That's research software for you! After my rewriting 2 065 regexes (out of 62 294) accepted one or fewer strings. Far more (16 833) returned errors.
Revocable credentials. Another approach is to build credentials that can be revoked in the event of bad behavior.

I remember flying up and then dropping down hard, hitting the side of one of the carts and then being thrown backwards, hitting hard flat onto the galley floor. My head and back slammed onto the floor and so did the little boy right beside me. His screams of fright and agony when he landed hard on his back still haunt me.”
