+# opencode-antigravity-auth ships only `dist/` in its npm tarball and relies on
+# runtime `dependencies` (@opencode-ai/plugin, @openauthjs/openauth, zod, ...).
+# opencode loads it via a file:// path and does NOT install those deps, so the

+# bun.lock and bun.nix are generated on the fly rather than committed.
+#
+# The tarball ships no lockfile, so we synthesize one with `bun install
+# --lockfile-only`. Resolving npm version ranges (e.g. "^4.1.4") into exact
+# versions requires registry access, and Nix only permits network inside a
+# fixed-output derivation — hence `lockfileHash` below. This is the single
+# unavoidable hash for the dep graph: it pins the resolved lockfile, which in
+# turn (via bun2nix -> fetchBunDeps) pins every transitive dependency, each
+# fetched as its own hash-checked FOD. bun.nix itself stays uncommitted and
+# is derived deterministically from the pinned lockfile.
+#
+# Bump `version`, `hash`, and `lockfileHash` together. To refresh lockfileHash,
