The container's output directory is not storage
Claude Code and agents
Symptom
The session's artifact directory was completely empty (zero files). Build artifacts and a copy of the signing key disappeared together.
Two lessons
- Pull artifacts down locally the moment they are created. The container is a cache, not storage.
- ★ Going from "it's not in the container" to "there's probably no backup either" was a guess, and it was wrong. The local backup saved it. Don't conclude beyond what you've measured.
