# Claude Code Stop hook — fires on every turn boundary, not just completion.
# Convention: the agent signals "this task is done" by writing a report file
# named .orchestra-report.md at the worktree root before stopping. If that
# marker is absent, this is an ordinary turn boundary and the hook is a
# no-op — do not treat every stop as completion (AUDIT.md B3).
#
# Requires: ORCHESTRA_TASK_ID and ORCHESTRA_URL set in the pane's env.
# Optional: ORCHESTRA_HARNESS_TOKEN if the server requires one.
#
# Reads the Stop hook's JSON payload from stdin (has "transcript_path" and
# "cwd"); needs jq.
