It exposes memory, resources and skills as one virtual filesystem under a viking:// protocol, so an agent navigates its context with ls, tree and find rather than opaque similarity queries, with content tiered into L0 abstract, L1 overview and L2 detail loaded on demand. v0.4.15 landed August 18 fixing an xxhash bug where vectors silently failed to persist; v0.4.14 the day before added MCP tree browsing and deleted the Qdrant and openGauss vector backends outright. (GitHub) Dropping two vector backends while adding filesystem navigation is a real architectural bet, not positioning. Agents are good at directory traversal because they've read a billion shell sessions. They're not good at reasoning about cosine distance.
