Pick the edge by (link_type, direction) or by role — the registry resolves a role name (e.g. managed_by, direct_reports) to the underlying link side. link_type wins when both are present.
How much of one material one store holds — one row per material × store, linked stock_level_for_material and stock_level_in_store (the ids ride on the row too, so a store’s board filters without a walk). on_hand is a cache with one writer: every movement verb records its stock_movement and moves this figure in the same transaction, under the level’s lock; the movements are the truth and recount_stock_level folds them to check it. Never below zero unless the store allows it. Carries the reorder_point (OPERA’s par) and when it was last counted. Minted by the first movement (or reorder point) for the pair.

Section titled “Parameters”Path Parameters
Section titled “Path Parameters”Object id (UUID v7, server-generated at create time).
Request Bodyrequired
Section titled “Request Bodyrequired”Body for POST .../traverse. At least one of link_type or role MUST be supplied — the server returns 422 missing_traversal_target when both are absent. link_type wins when both are set.
object
RFC3339 temporal window: return neighbours whose edge was in effect at this instant ([effective_from, effective_to)) instead of now.
Traverse through an open branch’s overlay view instead of the canonical (main) plane. Does not compose with as_of (422).
Edge direction. Optional when the binding is asymmetric.
API name of the link type to traverse. Narrowed to link types that bind the source. Wins over role.
Link-side role name (e.g. managed_by, direct_reports). Mutually substitutable with link_type — the registry resolves the role to its underlying link and direction.
Responses
Section titled “Responses”Neighbours along the resolved link.

{ "data": [ { "scope": { "level": "tenant" } } ], "direction": "out"}No object with that id, or link type unknown.
Validation error — must supply link_type or role.
