Package-manager channels

Doc type: How-to  ·  Applies to: POSE ≥ 0.9.0

Every channel below installs the exact same signed release artifact used by the verified install contract — no channel ever builds from source or repackages independently. Manifests are generated deterministically from checksums.txt and the release tag by pose release-package-manifests, run in CI only after the compatibility gate, the security gate and artifact-identity verification have all passed (spec pose-package-manager-distribution, R2).

Channels and support tiers

Channel	Format	Publication mechanism	Publication lag	Support tier
Homebrew	pose.rb formula	Attached to the GitHub release; brew install --formula <url> reads it directly — no upstream tap review	None — available the moment the release publishes	Maintained: exercised on every tagged release by the clean-host matrix
WinGet	3-file manifest set (version/installer/locale.en-US)	Generated in CI as a release artifact (pose-package-manifests); a maintainer submits it as a PR to microsoft/winget-pkgs	Days, gated by upstream Microsoft review — tracked per release in the closing spec's follow-ups until publication is automated	Maintained: manifest generation exercised on every tagged release; upstream publication is a manual, tracked step

Install commands:

# Homebrew (macOS, Linux)
brew install --formula https://github.com/oseiaspereira88/pose/releases/download/vX.Y.Z/pose.rb

# WinGet (Windows), once published to winget-pkgs
winget install Harne8.Pose

Verification

The Package channels CI workflow (.github/workflows/package-channels.yml) installs, runs pose doctor --json and uninstalls through each channel on an unmodified macOS and Windows runner for every published release (spec pose-package-manager-distribution, R3). A channel that fails this matrix blocks that release's support-tier claim, not the release itself — package channels are additive to the verified download-and-checksum contract, never a replacement for it.

Rollback

Every channel installs a specific pinned version. To roll back:

• Homebrew: re-run brew install --formula against the prior tag's pose.rb URL (release archives and formulas for all supported prior versions remain attached to their GitHub releases).
• WinGet: winget install Harne8.Pose --version <prior-version>, or uninstall and reinstall from the prior release's manifest artifact.

pose upgrade handles the repository contract/schema side of moving between versions once the new binary is on PATH; channel rollback only changes which binary is installed.
