v0.9.0

v0.9.0: the first stable release of Janus. Install it with Homebrew (brew install risadams/tap/janus), Scoop (scoop bucket add risadams https://github.com/risadams/scoop-bucket, then scoop install risadams/janus), or winget (winget install RisAdams.Janus, once Microsoft has reviewed the package); janus update leaves copies from all three to their own tools. The macOS binaries are signed and notarized, every archive's checksums are signed and its build attested, and a release rebuilds byte for byte from its tag. Since rc.17: the three package channels, and a baseline report on where a week of Claude Code's cost actually went.
