tardigrade-db

A KV-native persistent memory engine for LLM-driven systems, storing memory as quantized neural activations rather than text or embeddings.

Foundation-complete: persistent KV storage, latent-space retrieval, per-owner isolation, snapshot/restore, HTTP bridge, and CLI.

An LLM-native TypeScript library that makes Ink narratives two-sided: an LLM holds a persona and is forced to pick from author-defined choices — no freeform generation.

Puts the LLM in the player seat of a real Ink story, constraining output to a choice index and removing hallucinated branches from the failure surface.
