From 01a10de5d8222c8530de9e2d517cd34c1988f161 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Sat, 9 May 2026 21:43:27 +0200 Subject: [PATCH] test(i18n): non-empty + non-placeholder parity assertion MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase C4 audit found EN/DE locale files in perfect parity (1817 keys each, 0 drift, 0 empty values, 0 TODO/FIXME placeholders) — the five B-agents and the C2/C3 phases each shipped their own translations inline. This commit hardens the parity test to lock that state in: - empty-string assertion (per locale, fails on `"key": ""`) - key-equals-value assertion (fails when EN==DE==key.lastSegment, with an explicit allow-list for 5 legitimate cases: `settings.ntfy`, `classifications.{bp.Optimal,bp.Normal,pulse.Normal,bodyFat.Fitness}`) - TODO/FIXME/XXX/TBD assertion (per locale) EN-only key=value cases (e.g. `"of": "of"` where DE = `"von"`) are deliberately NOT flagged — those are natural, since key names derive from the EN word. The dual-locale check catches the real placeholder pattern (`"bugReport": "bugReport"` in both locales) without false positives.
