Perseus Computing LLC is a systems research laboratory building sovereign, mathematically verified cognitive architectures. Our flagship suite, Telarch Cognitive Infrastructure (TCI), delivers hard token budgeting, encrypted local memory, and cryptographic auditability for critical enterprise and defense applications. Deterministic performance. Sub-millisecond latency. Zero cloud dependencies.
Instead of an opaque, all-in-one framework, the Telarch Suite divides autonomous agent infrastructure into three focused, high-assurance engines that run entirely on your own hardware.
We evaluate speed, long-horizon memory recall, and concurrency using standard benchmark suites and multi-threaded stress tests—proving microsecond performance under load.
Evaluated across multi-session histories averaging 123,770 raw source tokens. Harpe compiles high-salience context down to 1,179 tokens (99.0% reduction) while preserving 98.20% Recall@10.

Test client-side encryption and contradiction defense. Encrypt sensitive agent memories, acquire exclusive write locks, and verify that revoked memories can never be resurrected by stale prompts.
Inspect a live cryptographic audit trail. Append real-time agent actions, simulate a single-bit corruption attack, and watch the verification engine catch the tampering in 46 microseconds.
From commercial enterprise deployments to classified defense software factories, the Telarch Suite is engineered to meet strict federal cybersecurity and auditability standards out of the box.

Key questions regarding Telarch pronunciation, etymology, sovereign air-gapped deployment, and our parent organization.
/ˈtɛl.ɑːrk/). The name derives from the Greek telos (purpose, completion, or end-state) and archē (first principle, sovereign leadership, or origin). It signifies deterministic infrastructure engineered from first principles toward purposeful autonomous task completion.
