macOS is no longer deferred — built natively on a Tart (Apple-Silicon)
runner (real hardware → licensed SDK, no grey area). Amendment documents
release-macos.yaml (dispatch-only, needs main), the libiconv de-nix +
ad-hoc re-sign, the runner-label `:host` backend nuance, generation-based
cache pruning, and D2-on-macOS (system libs only). All six D1 targets now
produce artifacts. Updates the deferred list + index entry.
Record the multi-platform build strategy as its own decision: cargo-zigbuild
for the four non-macOS targets, the static/standalone posture per platform,
the Windows synchronization stub, the test->build matrix workflow, and the
macOS deferral with its licensing rationale (the public CI image can't carry
the SDK). Shrinks the ci-001 amendment to a pointer; updates the index.
Runtime-verified by the user: Linux x86_64 + Windows aarch64 run correctly.
release.yaml becomes test (once, host) -> build (matrix) over the four
cargo-zigbuild targets; each matrix job uploads its binary + .sha256 to
the shared release (idempotent create-or-get). Records the expansion in
ADR-ci-001 (2026-06-13 amendment); macOS stays deferred.
Records the CI/release pipeline as ADR-ci-001 and relocates the nix-flake
ADR from main's ADR-0049 to ADR-ci-002 (content unchanged, history note
added). Both live in docs/ci/adr/ with a README index — a dated,
ci-segmented namespace disjoint from main's integer ADR sequence, the
same split the website subproject uses to avoid cross-branch number
collisions. Drops the ADR-0049 entry from docs/adr/README.
ci-001 covers the runner model, the baked nix CI image, the clippy+test
gate, the static-musl release on tag, trigger hygiene, auth, and scope.
