These notes are for vertical AI builders, agent platforms, and Cursor-like products that need context to be fresh, permission-aware, replayable, token-budgeted, and easy to query. TemporalStore handles most prompt-time context serving; MatrixDB and MatrixKV complement it only when hot database KV or strong consistency is needed.
Our flagship wedge: keep the intuitive hierarchy of filesystem-style context, then serve it through TemporalStore metadata, Milvus candidates, object refs, time windows, and replayable context packs.
A focused guide on time validity, stale-memory blocking, prompt replay, VikingMem-style event/entity memory, and why TemporalStore should be the serving core.
Why vector search and RAG are only the starting point. Production agents also need time validity, stale-memory blocking, replay, permissions, and trusted state.
MatrixArk helps vertical AI teams ship reliable copilots with trusted context packs, durable memory, replay, freshness, runtime reuse signals, and storage boundaries.
Start with one open-source Rust store for time-aware context serving: timelines, temporal KV, latest KV, freshness windows, replay, and prompt-ready memory.
Use the full stack when context becomes platform state: TemporalStore for serving, Milvus/S3 for semantic artifacts, MatrixDB for hot state and LMCache metadata, and MatrixKV for committed truth.
