0.9.8 — durable messaging + thread groups + grant propagation Phase 65/65b: spec/secret-grant propagation across restarts; turns never wedge on agent-process death. Phase 66/66a-f: durable delivery queue (deliveries.db), confirmed message_agent + message_status, deliveries observability, persistent unread badges from hub-side user read mark, screen session auto-restore + self-healing share link. Phase 67: user thread groups (folders, not labels) — hub routes + grouped collapsible client list. Phase 67.1: spawn frames pushed on grant changes (vault-loss fix); droplet worker boot-enable docs. hive-android: per-sender voices, double-tap select, voice picker fixes.
