Sprint 14 closed: Memory Temperature Map

Sprint 14 is closed. Knowledge Vitality is now visible in Meronq Desktop as a force-directed CEM graph — hot, warm, cold, and archived — with session-local Expand / Pack dials that never mutate shared SQLite (ADR-0013).

What shipped

• MemoryStore.getGraphSnapshot — ranked subgraph with containment layers, plus derived semantic edges (part_of, evidenced_with) so the map is not only a sun of contains through the project node.
• Sidecar GET /api/memory-graph — Desktop loads the temperature graph after Connect.
• Temperature Map — vis-network layout with a continuous heat-relief background, multi-select, edge labels only for the selection, and a persistent mount so clicks do not remount physics.
• Expand / Pack — session focus budget + estimated focus bytes; selection pulls 1-hop neighbors into focus without rewriting team memory.

Principle

Sprint 12: real work leaves a signal.

Sprint 13: measure memory health — and understanding with control values.

Sprint 14: see the temperature of that memory, and steer attention locally.

MCP wrappers named memory_expand / memory_pack remain follow-up; the Desktop dials are the product vocabulary for the same viewport model.
