From 0db120ed586b1a5d308240bdaaac63ec67196eae Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Thu, 12 Feb 2026 01:45:54 +0100 Subject: [PATCH] feat(client): Sprint 2 proof E2E tests + dynamic test snapshot (#357) Three E2E proof tests verify all acceptance criteria through the real server pipeline: player movement, v2 snapshot with visible_tiles, wall hiding (NPC behind wall invisible), corner reveal (move around wall to see NPC). Dynamic test snapshot tracks player position from queued inputs with simple LOS and Manhattan-distance visibility for standalone demo mode. 88 client + 112 server tests passing.
