# Upstream pins `requires-python = ">=3.11,<3.14"`, so this must NOT be built
# with the default `python3Packages` (which is 3.14.x on nixos-unstable and
# would be rejected by the build backend's requires-python check). Pin the
# 3.13 package set explicitly.
#
# `fastmcp[tasks]` is a HARD runtime dependency: `src/ssh_mcp/tools/exec_tools.py`
# does `from fastmcp.server.tasks import TaskConfig` at import time, and the
# decorator validates at import. nixpkgs' `fastmcp` installs only the
# client+server extras (optional-dependencies are passthru-only in nix and
# install nothing), so the `tasks` extra's backend -- pydocket -- has to be
# listed explicitly or the server crashes at startup.

# Internal dependency: upstream pins `unidiff>=0.7.5,<0.8.0`, but nixpkgs only
# carries 1.0.0. The 0.7.x API surface used by the ssh_edit tool
# (`PatchSet.from_string` and hunk iteration) is unchanged in 1.0.0, but
# buildPythonApplication's runtime-dep check enforces the specifier, so the
# pinned version still has to be provided. 0.7.5 is sdist-only on PyPI
# (no wheel), so this is a source build.
