Transcript

Draft script (not verified video transcript)

[Fetch] The edge case only happens at the edge.

[Junior Developer] That sentence is trying to be funny, but it is also the ticket.

[Agent A] I found eleven locations where rare means daily.

[Tiny CTO] Edge behavior needs observability, ownership, and rollback paths.

[Fetch] The logs say maybe, but in six time zones.

[Junior Developer] The reproduction steps include geography.

[Tiny CTO] Distributed systems turn small assumptions into regional personalities.

[Agent A] So the edge case got a passport before the roadmap did!
