# the in-process AG-UI adapter, so the AG-UI runtime (ag-ui-langgraph[fastapi],

# via core's [agui] extra) is a HARD dep. fastapi + uvicorn are already base

# deps above, so [agui] mainly adds ag-ui-langgraph itself.

# >=1.0.6 for the shared preflight primitive core.verify() used by `check --live`.

# >=1.0.9 for the relative-workspace idempotency fix (#66): _enter_workspace()

# chdirs into the workspace, and pre-1.0.9 workspace_root() doubled a relative root.

# Build the React/Vite SPA into langstage/static/ before the wheel is assembled, so a

# published wheel actually ships the web UI (gh #94). Without this, `artifacts` above only

# re-includes the git-ignored static/ tree *if it already exists* — a plain `uv build`

# never built it, so 0.13.20–0.13.23 shipped no frontend. See hatch_build.py. The hook is

# a no-op for editable installs (`pip install -e`) and skips when the SPA is already built,

# so Node is only needed to cut a real release wheel. `uv build` builds the wheel from the

# sdist, and both hatch_build.py and frontend/ (needed by the hook) are VCS-tracked and so

# ship in the default sdist.
