# Graft — local code-graph MCP tools every seat can call (token-saving retrieval; NanoNets, MIT).
# Installed here so connect (next) wires it into each CLI; the graph self-refreshes per query and is
# a no-op where a project has no index (built per project at crew launch). Non-fatal if it fails.
#
# We probe by BUILDING, not by `command -v graft`. A bin link proves nothing about whether graft can
# parse: it depends on ten tree-sitter native bindings, all wired as `"install": "node-gyp-build"`.
# npm v12 turns lifecycle scripts and implicit node-gyp builds OFF by default, and the prebuilds that
# save us do not cover every platform — tree-sitter core and tree-sitter-python ship no linux-arm64.
# There, the gyp fallback that used to compile them no longer runs, `graft` is still on PATH, and a
# presence check prints a green tick over a tool that throws on first use. So the probe indexes a
# one-file fixture (~0.2s) and requires the symbol back: exit 0 alone can mean "parsed nothing".
# Every failure path is explicitly `|| rc=1` rather than leaning on set -e being suspended inside an
# `if` condition: this must return a verdict, never abort setup.
