-M2.7 ⬜ edge closure (active task), M2.8 gate pending. All M3.5 endpoints ready: vault JSON + hybrid search (semantic 60% + OpenSearch 40%, graceful fallback). JWT auth live with Authentik. Awaiting: (1) Docker image rollout, (2) M2.7 verify implementation, (3) M8 dual-write + RRF fusion.

-Early work M3.7: `mem-core/src/lesson.rs` (871 LOC) signature extraction + tier lookup. 51/73 tasks complete (70%).
+**Current work:**
-**Tests: 247 passing, 2 ignored** (M2.1 +8 tests). Ready to tackle M2.2-8 (projections), M4.3 gate (skills composition), M5 (post-training), M7 (source connectors).
+- M8.1: OpenSearch StatefulSet (pod security baseline, fsGroup perms) — 2 commits pending (9a07659, 611f4d8)
+- Obsidian service: ✅ Deployed (ppatlabs/obsidian:latest, REST API on 27124)
+- All M3.5 endpoints ready: vault JSON + hybrid search (60% pgvector + 40% OpenSearch), JWT auth live with Authentik

 `M2.2` (CNPG manifest), `M5.4` (vLLM+LoRA), `M3.5.9` (git refs), and
 `M6.x` (agent-manager migration) are homelab/infra work independent of prior phases, can start parallel.
