      # drift from rc6 — if the wallet_ffi ABI mismatches the module build, fall
      # back to cherry-picking #629's one line onto e37876a and pin that commit.

  # NOTE: this flake is no longer built standalone; the repo-root flake.nix

  # its own — the AMM logic lives in the amm_ffi crate, which the amm_module
  # core module links; the UI reaches it via modules().amm_module (declared in
  # metadata.json `dependencies`). The repo-root flake exposes the UI as a named
  # attribute (there is no bare `default`): run it with `nix run .#amm-ui`, and
  # build the AMM logic crate with `nix build .#amm_ffi`.
