`core proposal-queue {status,list,show,review}`: a read + review-state-only
CLI over the two proposal sinks that had a Python API but no operator
surface — teaching/proposals/comprehension_failures/ (N5 contemplation)
and teaching/proposals/derived_close_facts/ (idle_tick PR-2 bridge).
"review" appends to a sidecar log (teaching/proposals/review_log.jsonl)
recording that a human looked at an artifact; it never mutates the
artifact, never ratifies, never mounts, never flips a flag. The existing
ratification corridor (teaching/proposals.py, `core teaching
proposals`/`review`, a different sink) is untouched.
Found and fixed a real bug while building the second sink's reader:
generate/determine/derived_close_proposals.py's DEFAULT_SINK used
parents[3] instead of parents[2], resolving one directory ABOVE the repo
instead of inside it. Silent because the feature is default-off and no
test asserted the path — confirmed live via a stray artifact sitting
outside the repository since 2026-06-16. Pinned by
test_derived_close_default_sink_resolves_inside_the_repo.
