Capabilities<br>Built on verifiable mathematics.<br>Not approximations or fuzzy similarity search. Every claim is provable, every number is measured in production.
Merkle Proofs<br>Every atom is cryptographically committed.<br>RFC 6962-compliant SHA-256 Merkle tree. Tamper with one atom — the root hash changes. AI clients verify integrity without trusting the server.<br>37% token savings vs raw proofs
Markov Prediction<br>Your next memory is already warm.<br>Variable-order Markov chain predicts which atoms you'll access next. Pre-fetches context before the query arrives. Weights decay at 0.5^(days/7) — recency matters.<br>64% hit rate in production
Sub-ms Recall<br>0.045ms p50. Not a typo.<br>LevelDB with JumpHash sharding across 4 independent Merkle trees. Dedicated instance means zero contention. No shared cluster, no noisy neighbours.<br>0.045ms p50 · 1.2ms p99
MCP-Native<br>25+ tools. Plug in, don't integrate.<br>Streamable HTTP MCP transport. Works with Claude, Cowork, and any MCP-compatible client. OAuth2 + Bearer auth. The client your AI already speaks.<br>25 MCP tools · Streamable HTTP
Architecture<br>From atom to proof in four steps.<br>No black boxes. Every stage is deterministic, measurable, and verifiable.
01Atom arrives<br>API call or MCP tool deposits a memory atom. Immediately hashed and committed to the Merkle tree.
02JumpHash routes to shard<br>The atom key is deterministically routed to one of 4 LevelDB shards via JumpHash — O(1), no coordination.
03Markov arc fires<br>The transition is recorded. The Markov predictor updates its weight table and schedules predictive prefetch.
04Proof returned<br>On read, the atom comes with a Merkle audit path. Client verifies root hash. Tamper-evident, always.
