# Phase 9 closure (UX-M7 regression gate): fail CI when a new raw
# `<table>` ships in production tsx outside the canonical DataTable
# + Skeleton primitives.
#
# Pre-Phase-9 the codebase had 19 `<table>` sites across 16 files.
# Two of those are LEGITIMATE primitives — they ARE the chokepoint
# every list page should route through:
#   • web/src/components/DataTable.tsx — the canonical table component
#   • web/src/components/Skeleton.tsx  — the loading-shape table-shaped
#                                         skeleton
#
# The other 14 page-level raw tables stay in place during the Phase 9
# rollout (the audit prompt's "DO NOT migrate all 18 in one PR" rule).
# This guard baseline-locks the existing 14; every migration to
# DataTable drops the baseline by 1. `--strict` mode rejects any raw
# table once the backlog clears.
#
# Tests are excluded.
