# smoke-graph-builder.sh — end-to-end smoke for `agentteam-insight graph`.
#
# Builds agentteam-insight, runs `graph --mode full` against the bundled tiny
# fixture repo, asserts the graph artifacts plus deterministic review.json are
# produced, and pipes the generated knowledge-graph.json through the
# compatibility validator.
#
# Usage:
#   scripts/smoke-graph-builder.sh                  # uses bundled fixture
#   scripts/smoke-graph-builder.sh /path/to/repo    # smoke a real repo
#   UNDERSTAND_ANYTHING_ROOT=/ua scripts/smoke-graph-builder.sh
#
# Exits non-zero if any step fails. Requires Go toolchain; UA parity step
# additionally requires UNDERSTAND_ANYTHING_ROOT and a built UA packages/core
# (run `pnpm --filter @understand-anything/core build` in the UA plugin dir).
