name: Closed-loop learning (weekly miss triage)

# Weekly reminder workflow for the closed-loop learning process documented
# in docs/closed-loop-learning.mdx. Runs at 09:00 UTC every Monday and
# also supports manual triggering.
#
# The workflow does not consume the per-user ``~/.opensre/misses.jsonl``
# store directly (that lives on engineer machines, not on the runner).
# Its purpose is to:
#   1) Open or refresh a tracking issue that nudges the on-call engineer
#      to run ``opensre misses stats --since 7d`` and then
#      ``opensre misses export --since 7d --top 10 --out tests/benchmarks/production_misses/``.
#   2) Verify the ``misses_command`` CLI surface is still wired and exits
#      cleanly, so the weekly process is not blocked by a CLI regression.
