- memcard.c: stop auto-creating blank cards when .mcd files don't exist; missing file now correctly means "no card in slot" - gpu.c: fix setup_textured_draw raw texture flag (was ? 0 : 0, now ? 1 : 0 for identity-modulation bypass) - gpu.c: add shaded quad vertex capture mechanism for Phase 4.5 debug (capture_quads / get_quads debug commands) - gte.cpp: add gte_exec_count to track total GTE compute commands executed (exposed via gte_state debug command) - debug_server.c: wire up capture_quads, get_quads commands and gte_exec field in gte_state response Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
