# Perseus Computing > Perseus is the system around the model: current context, governed memory, and reviewable evidence for consequential agent work. ## Platform components - [Perseus Context Engine](https://perseus.observer/context-engine/): resolves current workspace state into a bounded briefing. - [Perseus Vault](https://perseus.observer/vault/): preserves governed, time-valid memory in a local service. - [Perseus Ledger](https://perseus.observer/ledger/): records supplied events, evidence links, and authority references in a verifiable chain. ## Evaluate - [Security and deployment boundary](https://perseus.observer/security/) - [Methods and evidence](https://perseus.observer/benchmarks/) - [Current releases and setup paths](https://perseus.observer/docs/) - [Bounded product replay](https://perseus.observer/demo/) - [Defense and Government workshare](https://perseus.observer/government/) - [Vault API release entry](https://perseus.observer/vault/mcp-reference/) ## Source - [Source access status](https://perseus.observer/source/): repository browsing, release assets, and raw implementation reports are temporarily unavailable. ## Evidence policy Public figures keep their method, denominator, control, company-run or independent status, limitation, and source. Product behavior, benchmark evidence, security documentation, and procurement posture are separate claim classes.
