 # Decisions
 
+## 2026-06-10 – Rust/Go packages: -git → no-suffix tag-build (match what ships)
+
+- **Who**: Dominik, ClaudeCode
+- **Why**: `moonlock-git`/`moongreet-git`/`moonset-git`/`sshfsc-git` carried the `-git` suffix (Arch convention: VCS package, user builds HEAD locally) but the registry ships pre-built binaries — the user never builds. The suffix lied about what is distributed. corsairctl already did it right: no suffix, build from a versioned git tag (`#tag=v$pkgver`) — the official-Arch-repo model (versioned source, built centrally, distributed as binary).
+- **Tradeoffs**: A `-bin` style (project CI builds the binary, PKGBUILD installs only a release asset) was considered but rejected: it needs new build infra in each project repo, whereas tag-build is the smallest change to the existing two-stage CI and corsairctl already proves the pattern. The build stays in CI (no OOM-relevant change). Downside: per-package `update-pkgver` now reads the latest tag instead of `git describe`.
+- **How**: In moonarch-pkgbuilds, `git mv <name>-git <name>`; PKGBUILD drops `pkgver()`, sets fixed `pkgver` = latest tag, `source=...#tag=v$pkgver`, `pkgname` without suffix, `pkgrel=1`, plus `replaces=('<name>-git')` + `conflicts=('<name>-git')` for clean client migration on `pacman -Syu`. moongreet keeps `epoch=1` (2026-04-28 rollback) and its install hook. corsairctl added as-is (already tag-style). `moonarch-git` `depends` updated to the new names (pkgrel 12 → 13). Per-project `update-pkgver.yaml` switched to tag-trigger + `git describe --tags --abbrev=0`. Old `-git` registry versions deleted manually (the name change defeats the auto zombie-cleanup). Scope: `sshfsc` deferred (only tag v0.1.0, HEAD 11 commits ahead — needs a fresh tag first); `sweet-cursors` stays `-git` (no version tags upstream).
