https://imposm.org/docs/imposm3/latest/mapping.html#id - it says that:

The ID of the OSM node, way or relation. Relation IDs are negated (-1234 for ID 1234) to prevent collisions with way IDs.

As said in #239 the logic is more like

node = positive,
way negative
and relation negative < - 1e17.

This only applies to use_single_id_space which itself is an undocumented feature.
