# graphlemon A-1 spike driver.
# Tests whether Claude Code dynamic workflows can be invoked programmatically
# (headless, no human in the loop) with parseable structured output, per
# architecture.md §10.1 and SDD 00-SDD-生成记录.md assumption A-1.
#
# Usage: ./run-spike.sh /path/to/some/git/repo
# The target repo just needs to be *a* git repo -- it does not need to be
# graphlemon itself. Do not point this at a repo you care about disturbing;
# it only writes .claude/workflows/graphlemon-a1-spike.js into it.
