# gstack-review-read — read review log and config for dashboard
# Usage: gstack-review-read
#
# Emits, in order: reviews JSONL with computed review_freshness, ---CONFIG--- (skip_eng_review),
# ---HEAD--- (short sha), ---WTREE--- (current working-tree fingerprint from
# bin/gstack-wtree, or "unknown"), ---TREE--- (HEAD tree, informational) and
# ---DIRTY--- (tracked-file dirty flag). Consumers grade diff-scoped review
# rows using review_freshness; legacy or uncaptured diff evidence cannot fall
# back to HEAD equality. Plan rows are unchanged.
