name: Release desktop

# Build the signed Tauri desktop installers on a version tag and publish them as
# a Gitea Release — TWICE: once on this (private, source) repo for our own
# records/history, and once mirrored to mca/public_releases, which is what the
# Tauri auto-updater (apps/web/src/lib/desktop-updater.ts) actually points at.
#
# WHY a separate public repo: the updater runs on offline-first field appliances
# with no Gitea credentials, so its endpoint + installer downloads must be
# reachable unauthenticated. Mirroring compiled installers to a public
# releases-only repo avoids embedding any read token in the shipped app (which
# would leak the moment a booth PC is compromised — this box's threat model
# names the operator/booth as the primary adversary, see CLAUDE.md). Source
# stays private; only signed installers become public, same as most desktop
# software. mca/public_releases is shared across apps in the org, not
# parking-specific — namespace release tags/asset names accordingly if another
# app starts publishing there too.
#
# Trigger: push a tag like v0.1.0. The job builds .deb/.rpm/.AppImage, signs them
# with the updater key (Gitea secrets), assembles latest.json pointing at the
# MIRROR repo's asset URLs, uploads to both repos, and mirrors the same assets.
