MC #101646 — Memory/vector store decommission sweep

MC #101646 — Memory/vector store decommission sweep 
 Verdict: PARTIAL/BLOCKED. Safe cleanup completed; audit-retained archives and active canonical HiveMind were not deleted. 
 Actions completed 
 
 Archived zero-byte ghost ~/system/databases/bookstack.db to ~/system/_archive/orphan-dbs-2026-05/bookstack_db_20260521T114709Z.db . 
 Verified Mem0 runtime absent: no port 9000 listener and no active LaunchAgent/container evidence. 
 Verified Qdrant runtime absent: no containers, no volumes, no 6333/6334 listeners; compose is a commented rollback stub. 
 Verified orphan HiveMind paths from the audit are absent: ~/system/db/hivemind.db , ~/system/data/hivemind.db , ~/system/agents/hivemind/memory.db . 
 
 Retained intentionally 
 
 ~/system/databases/hivemind.db is canonical active HiveMind memory; integrity check passes and it must not be decommissioned by this cleanup task. 
 ~/system/backups/qdrant-mem0-archive-2026-05-09/ is retained per ADR-036 audit policy, including the Mem0/Qdrant snapshots. 
 ~/system/_archive/mem0-deprecated-2026-05-09/ is retained as historical source archive.

 Decision 
 This task should not delete canonical HiveMind or ADR-retained binary snapshots without a new explicit CEO/ops decision. The safe decommission surface is complete; the remaining storage is retained by design.
