Score: 7.7/10 (Innovation: 8, Technical: 8, Documentation: 6, Utility: 7)

Citadeld captures a CI failure environment and all context into a single replayable .cit file, allowing developers to reproduce and debug CI issues locally with hermetic replay semantics. This addresses a painful gap in debugging ephemeral CI failures, combining portability across Linux, macOS, and Android with honest runtime validation.

Target audience: backend devs, devops
