# Phase 6 closure (I18N-H2 regression gate): fail CI when a new
# `new Date(x).toLocaleString()` or `.toLocaleDateString()` ships in
# production tsx outside the canonical web/src/api/utils.ts impls.
#
# Pre-Phase-6 the codebase had 8 raw sites across 6 pages, each making
# its own locale + timezone choice. Phase 6 routed them through the
# formatDateTime / formatDate / <Timestamp> helpers in utils.ts +
# components/Timestamp.tsx. This guard prevents new raw sites from
# landing.
#
# Allowlist: web/src/api/utils.ts itself — those raw calls ARE the
# canonical implementation everyone else routes through.
#
# Tests are excluded (web/src/**/*.test.*) so test fixtures + assertions
# describing the pre-Phase-6 raw pattern don't trip the guard.
