Cache numeric tab/list/node state and eight transition boundaries without navigation I/O. Emit one expanded first-failure snapshot with up to 16 live callers per allocator route. Patch 0079 adds 11 anchors (139 -> 150); enable frontend hooks only in diagnostic mode. Verification: PS5_MEMORY_DIAGNOSTICS=1 bash tools/verify.sh (all five gates, 69 tests); python3 tools/check-memory-diagnostics.py. Evidence: evidence/xmb-first-failure-diagnostic/. Injected 10006 failures produce one expanded snapshot and 9404 bytes. Uploaded with verified readback; no console launch or runtime fix claimed.
