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.
