This repository contained LUCI project config files for a “tricium” LUCI project, which since been removed.
The reason for originally having a separate project was for security and organizational purposes, so that Tricium builders can be kept separate from other LUCI projects like “infra”, since Tricium analysis jobs don't need access to things like logs in other projects.
This became unnecessary with transition to recipe-based analyzers where all Tricium builders builders live in their respective projects, e.g. “fuchsia” and “chromium”.
