Storage stays UTC (DB TIMESTAMPTZ, API ISO-UTC) — only the display layer is localized, and now deterministically: every timestamp renders pinned to Asia/Jerusalem via a single Intl-based formatter, so SSR (UTC container) and the browser agree on any runtime. No layout/visible-format change — only the tz. - New single date formatter web-ui/src/lib/format-date.ts (G2): formatDate / formatDateShort / formatDateLong / formatDateTime / formatDateTimeFull / formatTime / formatIsoDate + Israel helpers getIsraelYear / israelDayKey / israelMidnightMs / israelParts + formatRelative (long/short/tight wording). - Routed all ad-hoc toLocaleDateString/toLocaleTimeString/toLocaleString + hand-rolled new Date(...).get*() / toISOString().slice(0,10) timestamp call sites (30 files) through it. Number toLocaleString left untouched. - Spec: added INV-UI9 to docs/spec/X6 (UTC storage, Asia/Jerusalem display). Display-only; no layout/design/IA change → Claude Design gate N/A. Invariants: G2 (single date formatter, no parallel ad-hoc formatting), INV-UI9. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
