Hanzo OS
Memory
What the company knows, and when it knew it.
The graph records assertions — an entity, a relation, a value, who said it and when it was so — and never overwrites one. A read takes two instants: as_of for when the world was so, as_known for how much had been heard. So a past answer can be reproduced exactly, and a correction does not erase what was believed before it. Each org’s own data lives in its Base, a SQLite store of its own.

| Method | Path | What it does |

POST | /v1/graph | Asserts what is true of an entity. |
GET | /v1/graph | Reads the assertions the org has recorded, bounded by as_of and as_known. |
POST | /v1/graph/resolve | What is in force about an entity as of an instant, and what disagreed. |
POST | /v1/graph/diff | What came into force, was superseded and was retracted between two instants. |
POST | /v1/graph/answer | Answers a question from the whole graph, citing the assertions it rests on. |
GET | /v1/base/bases | Lists every Base the caller can reach, one per org. |
