From b2ede3f0680edc894a54e28374cb87ab2690afa2 Mon Sep 17 00:00:00 2001 From: skal Date: Mon, 16 Feb 2026 14:32:59 +0100 Subject: refactor: remove v2 versioning artifacts, establish Sequence as canonical system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete v1→v2 migration cleanup: rename 29 files (sequence_v2→sequence, effect_v2→effect, 14 effect files, 8 shaders, compiler, docs), update all class names and references across 54 files. Archive v1 timeline. System now uses standard naming with all versioning removed. 30/34 tests passing.
