# opencode turn-boundary/completion poller — same rationale as
# orchestra-codex-poll.sh: opencode has no native Stop hook, so this runs as
# a background loop in the pane, polling /v1/harness/turn and watching for
# the .orchestra-report.md completion marker.
#
# opencode's own SSE session-status stream (OpenCodeStatus in
# internal/herdr/occupancy.go) is a fast path this script does not use — it
# would need the pane's session id, which isn't reliably known outside the
# opencode process. Instead this falls back to the same
# most-recently-written message file under opencode's storage dir that
# OpenCodeUsage already reads as its backstop (per AUDIT.md's "Real harness
# quota sources": "the SSE stream is not rock-solid").
#
# Requires: ORCHESTRA_TASK_ID, ORCHESTRA_URL, ORCHESTRA_WORKTREE set in the
# pane's env. Optional: ORCHESTRA_HARNESS_TOKEN,
# ORCHESTRA_POLL_INTERVAL (seconds, default 60).
# Needs: jq, find, curl.
