Why

GET /v1/memories//why. The evidence chain of one block as of a point in time, in the order it was said.

Walks causal, argumentative, and temporal edges out of one block and names each neighbour’s role. Only edges and nodes known at as_of are used, so the chain grows as as_of moves forward.

Parameters

id · string · required

as_of · timestamp or date · required

valid_at · timestamp

depth · integer · default: "3"

Response

chain · Link[]

Ordered by asserted_at. Each link: node (NodeRow), depth, path, via (edge type), role. Roles follow the edge type and direction: subject; cause / effect; contributing_cause / contributed_effect; trigger / triggered; preventer / prevented; support / supported; contradiction / contradicted; qualification / qualified; successor / predecessor; restatement / restated; concurrent.

reason · string

Only when chain is empty: not_yet or absent.
