From 6c85f4779433d0293d9a0d95b4b592c729a51ed0 Mon Sep 17 00:00:00 2001 From: Marcel Date: Mon, 15 Jun 2026 11:00:16 +0200 Subject: [PATCH] test(timeline): gate the event layer identity and the {@html} ban MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the REQ-001 structural-identity check (the event pills/world-bands render identically across all three grouping modes — the no-VRT-harness equivalent of the pixel-diff) and the REQ-009 grep gate (no lib/timeline component reaches for the raw-HTML directive). Reword the BucketHeaderChip doc to describe the directive by name so the gate stays literal.
