# Artifact command handler — `libreportal artifact <sub>`
# ---------------------------------------------------------------------------
# Dispatched automatically by cli_initialize.sh (category -> cliHandleArtifactCommands).
#
# The unified distribution primitive. The READ side (`index`/`applied`) fetches +
# verifies the team-signed artifact index (hotfixes today; apps/themes/components
# later — all one envelope) and lists what's available/applied; it changes nothing,
# so — like `updater check` — it runs directly. The state-changing `apply`/`revert`
# verbs route through the TASK system (snapshot → bounded declarative ops →
# auto-rollback → History), never a mutating API. See docs/roadmap/updates-and-
# distribution.md and cli_artifact_apply.sh.
