| """OpenViking memory plugin — full bidirectional MemoryProvider interface. |
| |
| OpenViking (Volcengine/ByteDance) organizes agent knowledge into a viking:// hierarchy |
| with tiered context (L0 abstract / L1 overview / L2 full), automatic memory extraction |
| on session commit, and semantic search. Config comes from env vars (OPENVIKING_ENDPOINT |
| / _API_KEY / _ACCOUNT / _USER / _AGENT) or a linked OpenViking CLI config (ovcli.conf). |
