# Implementer ↔ reviewer refinement loop.
#
# The reviewer emits a validated `review_report` artifact carrying a `verdict` field.
# The loop exits to `done` when verdict == "approved" and loops back to `implement`
# otherwise (verdict != "approved"). The runtime refinement guard caps the
# review→implement cycle at `implement.max_retries` iterations and then escalates.
#
# Requires a `review_report` artifact kind declared in config:
#   [[artifacts]]
#   id = "review_report"
#   schema_path = "schemas/review_report.json"
#   llm_emitted = true

id = "review_loop"
start = "implement"

# implement owns the work item across the loop: claim before starting, submit_for_review once
# the patch is ready, add notes (task_create one first if the work warrants tracking).

# review reads the task's own acceptance criteria (task_context) and completes it on an approved
# verdict (task_update action=complete); on changes_requested it leaves the task claimed.
