Public signed-runtime checkpoint for multimodal conversation-state isolation, progressive reasoning/content streaming, structured tool continuation, and architecture-aware prefix/paged/block-disk/TurboQuant KV cache behavior. Exact source: e1776a4. Full Python: 6203 passed, 96 skipped, 92 deselected. Full panel: 2346 passed, 3 skipped. Both Sequoia and Tahoe artifacts were Developer ID signed, notarized, stapled, Gatekeeper-accepted, installed, and live-tested through Electron on erics-m5-max.local. Broader family/stress/media rows remain tracked as PARTIAL and are not promoted by this checkpoint.
