Evidence
Evidence is the concrete origin of a fact: a source location and the fragment it was read from.
Every evidence record carries:
| Field | Meaning |
|---|---|
location |
Where it came from — path, line span, or artifact |
fragment |
The literal text or structure that supports the fact |
confidence |
0.0–1.0; deterministic recovery is 1.0, inferred material is lower |
created_at |
When the evidence was recorded |
Objects and relationships reference their evidence by id. When the compiler builds the CKM it sorts an object's evidence by confidence and picks the best fragment as its primary description.
This is the invariant that makes EKOS different from a search index: a conclusion with no evidence does not exist in the ledger. If you ask ekos_state for an object, you get the object, its relationships, and the evidence behind each.
