 # Options:
 #   --system         Install at system level (/usr/local/bin/orca, namespace /root/.orca). Requires root.

 #
 # Behavior:
 #   - Downloads the release tarball from the public Gitea release URL.
 #   - Extracts the orca binary to the install path.
+#   - If the resolved release (latest or pinned) has no matching binary
+#     asset, walks backward through recent releases to find one that does,
+#     and prints a warning. (REQ-098 — the v0.8.x releases shipped with
+#     zero binary assets, causing install to resolve to v0.4.5.)
 #   - If an existing orca binary is found, reads its version and prints
 #     "updated from X to Y" (in-place update; preserves config/db/certs).
 #   - Idempotent: re-running with the same version reinstalls the binary.
