# TDD-02-1: Commits should happen per-TURN, not per-TOOL
#
# GOAL: Verify we're NOT doing per-tool commits
#
# Per-tool commits (BAD): 1 commit for each tool call
#   - 10 tools = 10 tool commits
#
# Turn-level commits (GOOD): 1 commit for each turn
#   - 10 tools in 1 turn = 1 turn commit
#
# EXPECTED COMMITS:
#   - "agent initialized" (git init)
#   - "[agent:start] session began" (session start)
#   - "[agent:turn-N]" for each turn
#
# NOT EXPECTED:
#   - "[agent:tool]" commits (removed in this refactor)
