+  natively on a Tart Apple-Silicon runner via the dispatched
+  `release-macos.yaml`. All uploaded to the Gitea release with a
+  `.sha256` each. Decisions in `docs/ci/adr/` (ADR-ci-001/002/003).

+- [x] **D2** Single static binary, no runtime dependencies.
+  *(Done 2026-06-15, per platform: **Linux** is fully static (musl +
+  `crt-static`); **Windows** is a standalone `.exe` (Zig statically
+  links libc — no mingw runtime DLLs); **macOS** links only system
+  libraries (`libSystem` + the AppKit/Foundation frameworks —
+  inherent on every Mac, never user-installed; the build rewrites the
+  one nix-store `libiconv` path to `/usr/lib` and re-signs ad-hoc).
+  No target requires anything the user must install. ADR-ci-003.)*
 - [ ] **D3** Released via prebuilt binaries plus Homebrew, Scoop,
   `winget`, and `cargo binstall`.
+  *(Prebuilt binaries + checksums now published to Gitea releases
+  (D1); the package-manager manifests (Homebrew / Scoop / winget /
+  `cargo binstall`) remain to do. The asset naming
+  `rdbms-playground-<tag>-<target>` is already binstall-friendly.
